PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT

PD4442163, 4442183, 4442323, 4442363
4M-BIT CMOS SYNCHRONOUS FAST SRAM
PIPELINED OPERATION
DOUBLE CYCLE DESELECT
Description
The
µ
PD4442163 is a 262,144-word by 16-bit, the
µ
PD4442183 is a 262,144-word by 18-bit,
µ
PD4442323 is a
131,072-word by 32-bit and the
µ
PD4442363 is a 131,072-word by 36-bit synchronous static RAM fabricated with
advanced CMOS technology using Full-CMOS six-transistor memory cell.
The
µ
PD4442163,
µ
PD4442183,
µ
PD4442323 and
µ
PD4442363 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
µ
PD4442163,
µ
PD4442183,
µ
PD4442323 and
µ
PD4442363 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
µ
PD4442163,
µ
PD4442183,
µ
PD4442323 and
µ
PD4442363 are packaged in 100-pin PLASTIC LQFP with a
1.4 mm package thickness for high density and low capacitive loading.
