CY7C106D CY7C1006D 1-Mbit (256 K × 4) Static RAM 1-Mbit (256 K × 4) Static RAM Features Functional Description ■ Pin- and function-compatible with CY7C106B/CY7C1006B ■ High speed ❐ tAA = 10 ns ■ Low active power ❐ ICC = 80 mA @ 10 ns ■ Low CMOS standby power ❐ ISB2 = 3.0 mA ■ 2.0 V Data Retention ■ Automatic power-down when deselected ■ CMOS for optimum speed/power ■ TTL-compatible inputs and outputs ■ CY7C106D available in Pb-free 28-pin 400-Mil wide Molded SOJ package. CY7C1006D available in Pb-free 28-pin 300-Mil wide Molded SOJ package The CY7C106D [1] and CY7C1006D [1] are high-performance CMOS static RAMs organized as 262,144 words by 4 bits. Easy memory expansion is provided by an active LOW Chip Enable (CE), an active LOW Output Enable (OE), and tri-state drivers. These devices have an automatic power-down feature that reduces power consumption by more than 65% when the devices are deselected. The four input and output pins (IO0 through IO3) are placed in a high-impedance state when: ■ Deselected (CE HIGH) ■ Outputs are disabled (OE HIGH) ■ When the write operation is active (CE and WE LOW) Write to the device by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the four IO pins (IO0 through IO3) is then written into the location specified on the address pins (A0 through A17). Read from the device by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing Write Enable (WE) HIGH. Under these conditions, the contents of the memory location specified by the address pins appears on the four IO pins. Both CY7C106D and CY7C1006D devices are suitable for interfacing with processors that have TTL I/P levels. They are not suitable for processors that require CMOS I/P levels.

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. 11. 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. 12. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (c) of Figure 2 on page 5. Transition is measured when the outputs enter a high impedance state. 13. 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. 14. This parameter is guaranteed by design and is not tested. 15. The internal write time of the memory is defined by the overlap of CE and WE LOW. CE and WE must be LOW to initiate a write, and the transition of either of these signals can terminate the write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the write. 16. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD. Document Number: 38-05459 Rev. *K Page 7 of 16 CY7C106D CY7C1006D Switching Waveforms Figure 4.
