The first Reset command is interpreted as program data. How ever, FFH data is considered null data during programming operations (memory cells are only programmed from logica "1" to "0". The second Reset command safely aborts the programming operation and resets the device to the Read mode. When the MX26C2000B is delivered, or it is erased, the chip has all 2000K bits in the "ONE", or HIGH state. "ZEROs" are loaded into the MX26C2000B through the procedure of programming. ERASE ALGORITHM This detailed information is for your reference. It may prove esier to always issue the Reset command two consecutive times. This eliminates the need to determine if you are in the set-up Program state or not. The MX26C2000B do not required preprogramming before an erase operation. The erase algorithm is a close loop flow to simultaneously erase all bits in the entire array. Erase operation starts with the initial erase operation. Erase verification begins at address 0000H by reading data FFH from each byte. If any byte fails to erase. the entire chip is reerased. to a maximum for 30 pulse counts of 100ms duration for each pulse. The maximum cumulative erase time is 3s. However. the device is usually erased in no more than 3 pulses. Erase verification time can be reduced by storing the address of the last byte that failed. Following the next erase operation verification may start at the stored address location. JEDEC standard erase algorithm can also be used. But erase time will increase by performing the unnecessary preprogramming. SET-UP PROGRAM/PROGRAM A three-step sequence of commands is required to perform a complete program operation: Set Up ProgramProgram-Program Verify. The device is bulk erased and byte by byte programming. The command 40H is written to the command register to initiate Set Up Program operation. Address and data to be programmed into the byte are provided on the second WE pulse. Addresses are latched on the falling edge of the WE pulse, data are latched on the rising edge of the WE pulse. Program operation begins on the rising edge of the second WE pulse, and terminate of the next rising edge of the WE pulse. Refer to AC Characteristics and Waveforms for specific timing parameters. PROGRAM ALGORITHM The device is programmed byte by byte. A maximum of 25 pulses. each of 10us duration is allowed for each byte being programmed. The byte may be programmed sequentially or by random. After each program pulse, a program verify is done to determine if the byte has been successfully programmed. COMMAND REGISTER When high voltage is applied to VPP the command register is enabled. Read, write, standby, output disable modes are available. The read, erase, erase verify, program, program verify and Device ID are accessed via the command register. Standard microprocessor write timings are used to input a command to the register. This register serves as the input to an internal state machine which controls the operation mode of the device. An internal latch is used for write cycles, addresses and data for programming and erase operations. Programming then proceeds to the next desired byte location. JEDEC standard program algorithms can be used. RESET The Reset command initializes the MTP EPROMTM device to the Read mode. In addition, it also provides the user with a safe method to abort any device operation (including program or erase). The Reset command must be written two consecutive times after the set-up Program command (40H). This will safely abort any previous operation and initialize the device to the Read mode. P/N: PM0765 NO INTEGRATED STOP TIMER FOR ERASE Leading industry flash technology requires a stop timer built into the flash chip to prevent the memory cells from going into depletion due to over erase. The 2 Mbit MTP 3 REV. 0.7, OCT. 04, 2001 MX26C2000B EPROMTM is built on an innovative cell concept in which over erasing the memory cell is impossible. force 12.0 0.5 V on address line A9 of the device. Two identifier bytes may then be sequenced from the device outputs by toggling address line A0 from VIL to VIH. All other address lines must be held at VIL during auto identify mode. DATA WRITE PROTECTION Byte 0 ( A0 = VIL) represents the manufacturer code, and byte 1 (A0 = VIH), the device identifier code. For the MX26C2000B, these two identifier bytes are given in the Mode Select Table. All identifiers for manufacturer and device codes will possess odd parity, with the MSB (DQ7) defined as the parity bit. The design of the device protects against accidental erasure or programming. The internal state machine is automatically reset to the read mode on power-up. Using control register architecture, alteration of memory can only occur after completion of proper command sequences. The command register is only active when V is at high voltage. when V PP = V PPL , the device defaults PP to the Read Mode. Robust design features prevent inadvertent write cycles resulting from VCC power-up and power-down transitions or system noise. To avoid initiation of write cycle during VCC power-up, a write cycle is locked out for VCC less than 4V. The two- command program and erase write sequence to the command register provide additional software protection against spurious data changes. READ MODE The MX26C2000B has two control functions, both of which must be logically satisfied in order to obtain data at the outputs. Chip Enable (CE) is the power control and should be used for device selection. Output Enable (OE) is the output control and should be used to gate data to the output pins, independent of device selection. Assuming that addresses are stable, address access time (tACC) is equal to the delay from CE to output (tCE). Data is available at the outputs tOE after the falling edge of OE, assuming that CE has been LOW and addresses have been stable for at least tACC - tOE. PROGRAM VERIFY MODE Verification should be performed on the programmed bits to determine that they were correctly programmed. Verification should be performed with OE and CE, at VIL, WE at VIH, and VPP at its programming voltage. STANDBY MODE The MX26C2000B has a CMOS standby mode which reduces the maximum VCC current to 100 uA. It is placed in CMOS standby when CE is at VCC 0.3 V. The MX26C2000B also has a TTL-standby mode which reduces the maximum VCC current to 1.5 mA. It is placed in TTL-standby when CE is at VIH. When in standby mode, the outputs are in a high-impedance state, independent of the OE input. ERASE VERIFY MODE Verification should be performed on the erased chip to determine that the whole chip(all bits) was correctly erased. Verification should be performed with OE and CE at VIL, WE at VIH, and VCC = 5V, VPP = 12.5V AUTO IDENTIFY MODE SYSTEM CONSIDERATIONS The auto identify mode allows the reading out of a binary code from MTP EPROM that will identify its manufacturer and device type. This mode is intended for use by programming equipment for the purpose of automatically matching the device to be programmed with its corresponding programming algorithm. This mode is functional in the 25C 5C ambient temperature range that is required when programming the MX26C2000B. During the switch between active and standby conditions, transient current peaks are produced on the rising and falling edges of Chip Enable. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device. At a minimum, a 0.1 uF ceramic capacitor (high frequency, low inherent inductance) should be used on each device between VCC and GND to minimize transient effects. In addition, to overcome the voltage drop caused by the inductive To activate this mode, the programming equipment must P/N: PM0765 4 REV. 0.7, OCT. 04, 2001 MX26C2000B effects of the printed circuit board traces on EPROM arrays, a 4.7 uF bulk electrolytic capacitor should be used between VCC and GND for each of the eight devices. The location of the capacitor should be close to where the power supply is connected to the array. OUTPUT DISABLE Output is disabled when OE is at logre high. When in output disabled all circuitry is enabled. Except the output pins are in a high impedance state(TRI-ATATE).

The two-step command prevents accidental alteration to memory array. Erase operation starts with the rising edge of the WE pulse and terminates with the rising edge of the next WE pulse, which in this case is the erase verify command. COMMAND MODE The 2 Mbit MTP EPROMTM is in Command mode when high voltage VPPH is applied to the VPP pin. In this state the available functions are Read, Program, Program Verify, Eraseand Erase Verify. Reset are selected by writing commands to the input register. Data from the register are input to the state machine. The output from the state machine determines the function of the device. The command register serves as a latch to store data for executing commands. It does not occupy address- able memory location. Standard microprocessor write timing is used. Table 2 defines the register commands. The command register is written by bringing WE to a logic-low Level (V IL), while CE is low. Addresses are latched on the falling edge of WE, while data is latched on the rising edge of the WE pulse. ERASE VERIFY Each erase operation is followed by an erase verify. The command A0H is written into the command register. The address of the bytes to be verified is supplied with the command. The address is latched on the falling edge of the WE pulse. A reading FFH is returned to confirm all bits in the byte are erased. This sequence of Set Up Erase- Erase continues for each address until FFH is returned. This indicates the entire memory array is erased and completes the operation. Erase verify operation starts at address 0000H and ends at the last address. Maximum erase pulse duration for the 2Mbit MTP EPROMTM is 100ms with a maximum 30 pulses. Refer to AC Characteristics and Waveforms for specific timing parameters. Standby and Output disable functions are the same as in Read Mode, controlled by CE and OE. If the device is deselected during erasure, programming, or erase/program verification, the device draws active current until the operations terminate. READ COMMAND To read memory content, write 00H into the command register while high voltage is applied to V PP pin (VPP = VPPH ). Microprocessor read cycle retrieves the data . The device remains enable for read until the data in the command register are altered. The device is default in read mode when power up. This is to ensure no accidental alteration of the memory occurs during power transition. Refer to AC Read Characteristics and Waveforms for specific timing parameters. SET UP ERASE/ERASE Preprogram operation is not required prior to the erase operation. A sequence of commands is required to perform a complete erase operation: set up erase, erase, and erase verify. High voltage is applied to the V PP pin (VPP=VPPH). The command 20H is written to the command register to initiate the set-up erase mode. ERASE OPERATION The same command, 20H, is again written to the command register.
