CY7C1006BN

CY7C106BN CY7C1006BN 256K x 4 Static RAM Features • High speed — tAA = 15 ns • CMOS for optimum speed/power • Low active power — 495 mW • Low standby power — 275 mW • 2.0V data retention (optional) • Automatic power-down when deselected • TTL-compatible inputs and outputs Functional Description The CY7C106BN and CY7C1006BN 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 three-state drivers. These devices have an automatic power-down feature that reduces power consumption by more than 65% when the devices are deselected. Writing to the devices is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. Data on the four I/O pins (I/O0 through I/O3) is then written into the location specified on the address pins (A0 through A17). Reading from the devices is accomplished 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 will appear on the four I/O pins. The four input/output pins (I/O0 through I/O3) are placed in a high-impedance state when the devices are deselected (CE HIGH), the outputs are disabled (OE HIGH), or during a write operation (CE and WE LOW). The CY7C106BN is available in a standard 400-mil-wide SOJ; the CY7C1006BN is available in a standard 300-mil-wide SOJ.

Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified IOL/IOH and 30–pF load capacitance. 6. tHZOE, tHZCE, and tHZWE are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ±500 mV from steady-state voltage. 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. 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. 9. The minimum write cycle time for Write Cycle No. 3 (WE controlled, OE LOW) is the sum of tHZWE and tSD.
