CY7C1041CV33 4-Mbit (256 K × 16) Static RAM 4-Mbit (256 K × 16) Static RAM Features Functional Description ■ Temperature ranges ❐ Industrial: –40 °C to 85 °C The CY7C1041CV33 is a high performance CMOS static RAM organized as 262,144 words by 16 bits. ■ Pin and function compatible with CY7C1041BV33 ■ High speed ❐ tAA = 8 ns ■ Low active power ❐ 360 mW (max) To write to the device, take Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (/IO0 through I/O7), is written into the location specified on the address pins (A0 through A17). If Byte High Enable (BHE) is LOW, then data from IO pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A17). ■ 2.0 V data retention ■ Automatic power down when deselected ■ TTL-compatible inputs and outputs ■ Easy memory expansion with CE and OE features ■ Available in Pb-free 44-pin TSOP II package To read from the device, take Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory appears on I/O8 to I/O15. For more information, see the Truth Table on page 10 for a complete description of Read and Write modes. The input and output pins (I/O0 through I/O15) are placed in a high impedance state when the device is deselected (CE HIGH), the outputs are disabled (OE HIGH), the BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW).

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, and input pulse levels of 0 to 3.0 V. 6. tPOWER gives the minimum amount of time that the power supply is at typical VCC values until the first memory access is performed. 7. At any temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any device. 8. tHZOE, tHZCE, tHZBE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of Figure 2 on page 6. Transition is measured 500 mV from steady state voltage. 9. The internal write time of the memory is defined by the overlap of CE LOW, WE LOW, and BHE/BLE LOW. CE, WE, and BHE/BLE must be LOW to initiate a write. The transition of these signals terminate the write. The input data setup and hold timing is referenced to the leading edge of the signal that terminates the write. 10. The minimum Write cycle time for Write Cycle No. 3 (WE Controlled, OE LOW) is the sum of tSD and tHZWE. Document Number: 38-05134 Rev. *R Page 7 of 17 CY7C1041CV33 Switching Waveforms Figure 3.
