8M-BIT CMOS SYNCHRONOUS FAST SRAM
FLOW THROUGH OPERATION
Description
The
μ
PD4482161 is a 524,288-word by 16-bit, the
μ
PD4482181 is a 524,288-word by 18-bit, the
μ
PD4482321 is a
262,144-word by 32-bit and the
μ
PD4482361 is a 262,144-word by 36-bit synchronous static RAM fabricated with
advanced CMOS technology using Full-CMOS six-transistor memory cell.
The
μ
PD4482161,
μ
PD4482181,
μ
PD4482321 and
μ
PD4482361 integrate 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
PD4482161,
μ
PD4482181,
μ
PD4482321 and
μ
PD4482361 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
PD4482161,
μ
PD4482181,
μ
PD4482321 and
μ
PD4482361 are packaged in 100-pin PLASTIC LQFP with a 1.4
mm package thickness for high density and low capacitive loading.
