The Byte High Enable (BHE) and Byte Low Enable (BLE) inputs control write operations to the upper and lower bytes of the specified memory location. BHE controls I/O8 through I/O15 and BLE controls I/O0 through I/O7. High speed tAA = 10 ns / 15 ns Low active and standby currents Active current: ICC = 38-mA typical Standby current: ISB2 = 6-mA typical Operating voltage range: 1.65 V to 2.2 V, 2.2 V to 3.6 V, and 4.5 V to 5.5 V 1.0-V data retention TTL-compatible inputs and outputs Pb-free 44-pin SOJ, 44-pin TSOP II, and 48-ball VFBGA packages Functional Description CY7C1041GN is high-performance CMOS fast static RAM Organized as 256K words by 16-bits. Data reads are performed by asserting the Chip Enable (CE) and Output Enable (OE) inputs LOW and providing the required address on the address lines. Read data is accessible on the I/O lines (I/O0 through I/O15). Byte accesses can be performed by asserting the required byte enable signal (BHE or BLE) to read either the upper byte or the lower byte of data from the specified address location. All I/Os (I/O0 through I/O15) are placed in a high-impedance state during the following events: The device is deselected (CE HIGH) The control signals (OE, BLE, BHE) are de-asserted The logic block diagram is on page 2.

Test conditions assume a signal transition time (rise/fall) of 3 ns or less, timing reference levels of 1.5 V (for VCC > 3 V) and VCC/2 (for VCC < 3 V), and input pulse levels of 0 to 3 V (for VCC > 3 V) and 0 to VCC (for VCC < 3 V). Test conditions for the read cycle use output loading, as shown in part (a) of Figure 4 on page 6, unless specified otherwise. 12. For all dual chip enable devices, CE is the logical combination of CE1 and CE2. When CE1 is LOW and CE2 is HIGH, CE is LOW; when CE1 is HIGH or CE2 is LOW, CE is HIGH. 13. tHZOE, tHZCE, tHZWE, tHZBE, tLZOE, tLZCE, tLZWE, and tLZBE are specified with a load capacitance of 5 pF, as shown in part (b) of Figure 4 on page 6. Transition is measured 200 mV from steady state voltage. 14. These parameters are guaranteed by design and are not tested. 15. The internal write time of the memory is defined by the overlap of WE = VIL, CE = VIL, and BHE or BLE = VIL. These signals must be LOW to initiate a write, and the HIGH transition of any of these signals can terminate the operation. The input data setup and hold timing should be referenced to the edge of the signal that terminates the write. 16. The minimum write cycle pulse width in Write Cycle No. 2 (WE Controlled, OE LOW) should be equal to sum of tSD and tHZWE.
