DATA SHEET

MOS INTEGRATED CIRCUIT

PD4482162, 4482182, 4482322, 4482362

8M-BIT CMOS SYNCHRONOUS FAST SRAM

PIPELINED OPERATION

SINGLE CYCLE DESELECT

Description

The µPD4482162 is a 524,288-word by 16-bit, the µPD4482182 is a 524,288-word by 18-bit, µPD4482322 is a 262,144-

word by 32-bit and the µPD4482362 is a 262,144-word by 36-bit synchronous static RAM fabricated with advanced CMOS

technology using Full-CMOS six-transistor memory cell.

The µPD4482162, µPD4482182, µPD4482322 and µPD4482362 integrates unique synchronous peripheral circuitry, 2-

bit burst counter and output buffer as well as SRAM core. All input registers are controlled by a positive edge of the single

clock input (CLK).

The µPD4482162, µPD4482182, µPD4482322 and µPD4482362 are suitable for applications which require synchronous

operation, high speed, low voltage, high density and wide bit configuration, such as cache and buffer memory.

ZZ has to be set LOW at the normal operation. When ZZ is set HIGH, the SRAM enters Power Down State (“Sleep”). In

the “Sleep” state, the SRAM internal state is preserved. When ZZ is set LOW again, the SRAM resumes normal operation.

The µPD4482162, µPD4482182, µPD4482322 and µPD4482362 are packaged in 100-pin PLASTIC LQFP with a 1.4

mm package thickness for high density and low capacitive loading.

/BW1, /BW2, /BWE (µPD4482162, µPD4482182)

Global write enable : /GW

• Three chip enables for easy depth expansion

• Common I/O using three state outputs
