PRELIMINARY DATA SHEET
Description
The
PD4442163-Y is a 262,144-word by 16-bit, the
PD4442183-Y is a 262,144-word by 18-bit,
PD4442323-Y is
a 131,072-word by 32-bit and the
PD4442363-Y is a 131,072-word by 36-bit synchronous static RAM fabricated with
advanced CMOS technology using Full-CMOS six-transistor memory cell.
The
PD4442163-Y,
PD4442183-Y,
PD4442323-Y and
PD4442363-Y 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
PD4442163-Y,
PD4442183-Y,
PD4442323-Y and
PD4442363-Y 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
PD4442163-Y,
PD4442183-Y,
PD4442323-Y and
PD4442363-Y are packaged in 100-pin PLASTIC LQFP
with a 1.4 mm package thickness for high density and low capacitive loading.
