CY7C1021D 1-Mbit (64 K × 16) Static RAM 1-Mbit (64 K × 16) Static RAM Features ■ Functional Description The CY7C1021D is a high performance CMOS static RAM organized as 65,536 words by 16 bits. This device has an automatic power down feature that significantly reduces power consumption when deselected. The input and output pins (IO0 through IO15) are placed in a high impedance state when the device is deselected (CE HIGH), outputs are disabled (OE HIGH), BHE and BLE are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). Write to the device by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (IO0 through IO7), is written into the location specified on the address pins (A0 through A15). If Byte High Enable (BHE) is LOW, then data from I/O pins (IO8 through IO15) is written into the location specified on the address pins (A0 through A15). Read from the device by taking 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 appears on IO0 to IO7. If Byte High Enable (BHE) is LOW, then data from memory appears on IO8 to IO15. See the Truth Table on page 10 for a complete description of read and write modes.

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5 V, input pulse levels of 0 to 3.0 V, and output loading of the specified IOL/IOH and 30-pF load capacitance. 6. tPOWER gives the minimum amount of time that the power supply should be at typical VCC values until the first memory access can be performed. 7. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 8. tHZOE, tHZBE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in (c) of Figure 2 on page 5. Transition is measured when the outputs enter a high impedance state. 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, and the transition of these signals can terminate the write. The input data setup and hold timing should be referenced to the leading edge of the signal that terminates the write.
