Description
The
PD4382162 is a 524,288-word by 16-bit, the
PD4382182 is a 524,288-word by 18-bit,
PD4382322 is a 262,144-
word by 32-bit and the
PD4382362 is a 262,144-word by 36-bit synchronous static RAM fabricated with advanced CMOS
technology using N-channel four-transistor memory cell.
The
PD4382162,
PD4382182,
PD4382322 and
PD4382362 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
PD4382162,
PD4382182,
PD4382322 and
PD4382362 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
PD4382162,
PD4382182,
PD4382322 and
PD4382362 are packaged in 100-pin plastic LQFP with a 1.4 mm
package thickness for high density and low capacitive loading.
Features
3.3 V (Chip) / 3.3 V or 2.5 V (I/O) Supply
Synchronous operation
Internally self-timed write control
Burst read / write : Interleaved burst and linear burst sequence
Fully registered inputs and outputs for pipelined operation

PD4382322,
PD4382362), 4.0 ns (133 MHz) (
PD4382162,
PD4382182)
Asynchronous output enable : /G
Burst sequence selectable : MODE
Sleep mode : ZZ (ZZ = Open or Low : Normal operation)
Separate byte write enable :
/BW1 - /BW4 (
PD4382322,
PD4382362), /BW1 - /BW2 (
PD4382162,
PD4382182), /BWE
Global write enable : /GW
Three chip enables for easy depth expansion
Common I/O using three state outputs
