M × 4) Static RAM

Features

Functional Description

■ Pin- and function-compatible with CY7C1046B

The CY7C1046D^[1]is a high-performance CMOS static RAM

organized as 1M 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. Writing to the device

is accomplished by taking Chip Enable (CE) and Write Enable

(WE) inputs LOW. Data on the four I/O pins (I/O₀through I/O₃)

is then written into the location specified on the address pins

(A₀through A₁₉).

■ High speed

❐ t_AA= 10 ns

■ CMOS for optimum speed/power

■ Low active power

❐ I_CC= 90 mA @ 10 ns

Reading from the device 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 I/O pins.

■ Low CMOS Standby Power

❐ I_SB2= 10 mA

■ Data Retention at 2.0 V

■ Automatic power-down when deselected

■ TTL-compatible inputs and outputs

The four input/output pins (I/O₀through I/O₃) are placed in a

high-impedance state when the device is deselected (CE

HIGH), the outputs are disabled (OE HIGH), or during a write

operation (CE LOW, and WE LOW).

■ Easy memory expansion with CE and OE features

■ Available in lead-free 400-mil-wide 32-pin SOJ package

The CY7C1046D is available in a standard 400-mil-wide

32-pin SOJ package with center power and ground

(revolutionary) pinout.
