CY7C1041CV33 4-Mbit (256K x 16) Static RAM Features Functional Description ■ The CY7C1041CV33 is a high performance CMOS static RAM organized as 262,144 words by 16 bits. Temperature ranges ❐ Commercial: 0°C to 70°C ❐ Industrial: –40°C to 85°C ❐ Automotive-A: –40°C to 85°C ❐ Automotive-E: –40°C to 125°C ■ Pin and function compatible with CY7C1041BV33 ■ High speed ❐ tAA = 10 ns (Commercial, Industrial and Automotive-A) ❐ tAA = 12 ns (Automotive-E) 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 IO pins (IO0 through IO7), 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 (IO8 through IO15) is written into the location specified on the address pins (A0 through A17). 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 IO0 to IO7. If Byte High Enable (BHE) is LOW, then data from memory appears on IO8 to IO15. For more information, see the Truth Table on page 9 for a complete description of Read and Write modes. ■ Low active power ❐ 324 mW (max) ■ 2.0V data retention ■ Automatic power down when deselected ■ TTL-compatible inputs and outputs ■ Easy memory expansion with CE and OE features ■ Available in Pb-free and non Pb-free 44-pin 400 Mil SOJ, 44-pin TSOP II and 48-Ball FBGA packages The input and output pins (IO0 through IO15) 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). For best practice recommendations, refer to the Cypress application note AN1064, SRAM System Guidelines.

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, and input pulse levels of 0 to 3.0V. 5. tPOWER gives the minimum amount of time that the power supply is at typical VCC values until the first memory access is performed. 6. 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. 7. tHZOE, tHZCE, tHZBE, and tHZWE are specified with a load capacitance of 5 pF as in part (d) of AC Test Loads and Waveforms on page 5. Transition is measured ±500 mV from steady state voltage. 8. 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. 9. The minimum Write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
