Table 2. Signal Descriptions (Sheet 1 of 2) Symbol Type Descriptions ADDRESS INPUTS for memory addresses of a SCSP device with: A[Max:0] D[15:0] CE#1 CE#2 Input Input/ Output Input * * * 32-Mbit density: A[Max]=A20 64-Mbit density: A[Max]=A21 128-Mbit density: A[Max]=A22 DATA INPUTS/OUTPUTS: Inputs data and commands during writing cycles, outputs data during memory, status register, protection register and configuration code reads. These signals float when the die or outputs are deselected. Data is internally latched during writes. FLASH CHIP ENABLE: CE#-low selects the flash component. When asserted, the flash internal control logic, input buffers, decoders, and sense amplifiers are activated. When deasserted, the flash die is deselected, power reduces to standby levels, and data and WAIT outputs are placed in high-Z state. CE#1 connects to flash die#1 Chip Enable while CE#2 connects to flash die#2 Chip Enable. CE#2 is only connected for stacked combinations with 2 flash dies. RST# OE#1 OE#2 WE# ADV# CLK Input Input Input FLASH RESET: RST#-low resets flash internal circuitry and inhibits write operations. This function may be employed to provide data protection during power transitions. After exiting the reset state (RST# returned to logic-high), the selected flash die resumes operation in asynchronous read-array mode. FLASH OUTPUT ENABLE: OE#-low activates device output through the flash data buffers during a flash read cycle. When deasserted, the flash outputs tri-state to high-Z. OE#1 connects to flash die#1 Output Enable while OE#2 connects to flash die#2 Output Enable. OE#2 is only connected for stacked combinations with 2 flash dies. FLASH WRITE ENABLE: WE# controls writes to the selected flash die. WE#-low allows input to the flash CUI, array, PR/PLR, RCR, or block lock bits. Addresses and data are latched on this signal's rising edge. Input FLASH ADDRESS VALID: ADV# indicates valid address presence on address inputs of the selected flash die. During synchronous read operations, all addresses are latched on ADV#'s rising edge or CLK's rising (or falling) edge, whichever occurs first. Input FLASH CLOCK: CLK synchronizes the selected flash die to the system bus frequency in synchronous-read configuration and increments an internal burst address generator. During synchronous read operations, addresses are latched on ADV#'s rising edge or CLK's rising (or falling) edge, whichever occurs first. CLK is only used for synchronous mode. Refer to flash product discrete datasheet for information how to use this signal in asynchronous mode. FLASH WAIT: Wait is driven when CE# is asserted. Flash RCR[10][WP] determines the WAIT asserted logic level. * WAIT Output In synchronous array read modes, WAIT indicates invalid data when asserted and valid data when de-asserted. * In synchronous non-array read modes, asynchronous page mode, and all write modes, WAIT is asserted. Refer to flash product discrete datasheet for more information. Datasheet 11 Table 2.

Datasheet 25 12.0 PSRAM Operations 12.1 Power-up Sequence and Initialization The PSRAM functionality and reliability are independent of the power-up slew rate of the core PVCC. Any power-up slew rate is possible under use conditions. The following power up sequence and operation should be used before starting normal operation. The PSRAM power-up sequence is represented in Figure 8. Following power application, make PMode high level after fixing P-Mode to low level for the period of tVHMH. Make P-CS# high level before making P-Mode high level. Then, P-CS# and P-Mode are fixed to high level for the period of tMHCL. Normal Operation is possible once the power up sequence is complete. Figure 8. Timing Waveform for Power up sequence Initialization Normal Operation P-CS# tMHCL tCHMH P-Mode tVHMH P-Vcc Vcc (MIN) NOTES: 1. Make P-Mode low level when starting the power supply. 2. tVHMH is specified from when the power supply voltage reaches the prescribed minimum value (P-Vcc (MIN)) Table 14. Initialization timing Parameter 12.2 Symbol MIN MAX Unit Power application to P-Mode low level hold tVHMH 50 us P-CS# high level to P-Mode high level tCHMH 0 ns Following power application, P-Mode high level hold to P-CS# low level tMHCL 200 us Mode Register The PSRAM die has an internal register that helps control the Low Power mode of the PSRAM. This register is called the Mode register. The densities that can be selected for performing refresh are 16 Mbits, 8 Mbits, 4 Mbits and 0 Mbit. The density for performing refresh can be set with the Mode register. Once the refresh density has been set in the Mode register, these settings are retained until they are set again, while applying the power supply. However, the Mode register setting will become undefined if the power is turned off, so set the Mode register again after power application. 26 Datasheet 12.2.1 Mode Register Setting Since the initial value of the Mode register at power application is undefined, be sure to set the Mode register after initialization at power application. When setting the density of partial refresh, data before entering the Low Power Mode is not guaranteed.(This is the same for resetup) However, since Low Power Mode is not entered unless P-Mode=L, when partial refresh is not used, it is not necessary to set the Mode register. Moreover, when using page read without using partial refresh, it is not necessary to set the Mode register. The Mode register setting mode can be entered by successively writing two specific data after two continuous reads of the highest address. The Mode register setting is a continuous four-cycle operation - two read cycles and two writes cycles. See Table 15 for setting Mode register command sequence. Table 15.

If incorrect addresses or data are written, or if addresses or data are written in the incorrect order, the setting of the Mode register is not performed correctly. When the highest address is read consecutively three or more times, the Mode register setting entries are not performed correctly. (Immediately after the highest address is read, the setting of the Mode register is not performed correctly.) Perform the setting of the Mode register after power application or after accessing other than the highest address. Once the refresh density has been set in the Mode register, these settings are retained until they are set again, while applying the power supply. However, the Mode register setting will become undefined if the power is turned off, so set the Mode register again after power application. 28 Datasheet 12.3 Low Power mode In addition to the regular Standby mode with a full density data hold, Low Power mode performs partial density data refresh or zero density data refresh. The Low Power mode allows customers to turn off sections of the PSRAM die to save refresh current. The PSRAM die is divided into four sections allowing certain sections to be refreshed with P-Mode tied Low. In regular Standby mode, both P-CS# and P-Mode are high level. But in Low Power mode, PMode is low level. In Low Power mode, if 0M bit is set as the density, it is necessary to perform initialization the same way as after applying power, in order to return to normal operation from Low Power mode. Refer to Figure 8, "Timing Waveform for Power up sequence" on page 26 for timing charts. When the density has been to set to 16 Mbits, 8 Mbits, or 4 Mbits in Low Power mode, it is not necessary to perform initialization to return to normal operation from Low Power mode. For timing charts, refer to Figure 11, "Low Power mode -Entry/Exit (16/ 8/ 4/ 0 Mbits)" Figure 11.
