Description
The
碌
PD4482163 is a 524,288-word by 16-bit, the
碌
PD4482183 is a 524,288-word by 18-bit,
碌
PD4482323 is a 262,144-
word by 32-bit and the
碌
PD4482363 is a 262,144-word by 36-bit synchronous static RAM fabricated with advanced CMOS
technology using Full-CMOS six-transistor memory cell.
The
碌
PD4482163,
碌
PD4482183,
碌
PD4482323 and
碌
PD4482363 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
碌
PD4482163,
碌
PD4482183,
碌
PD4482323 and
碌
PD4482363 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 (鈥淪leep鈥?. In
the 鈥淪leep鈥?state, the SRAM internal state is preserved. When ZZ is set LOW again, the SRAM resumes normal operation.
The
碌
PD4482163,
碌
PD4482183,
碌
PD4482323 and
碌
PD4482363 are packaged in 100-pin PLASTIC LQFP with a 1.4
mm package thickness for high density and low capacitive loading.
