UPD44164184 Product details

Description

The µPD44164084 is a 2,097,152-word by 8-bit, the µPD44164184 is a 1,048,576-word by 18-bit and the µPD44164364 is a 524,288-word by 36-bit synchronous double data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.The µPD44164084, µPD44164184 and µPD44164364 integrates unique synchronous peripheral circuitry and a burst counter.All input registers controlled by an input clock pair (K and /K) are latched on the positive edge of K and /K.These

Features

1.8 ± 0.1 V power supply and HSTL I/O.
DLL circuitry for wide output data valid window and future frequency scaling.
Pipelined double data rate operation.
Common data input/output bus.
Four-tick burst for reduced address frequency.
Two input clocks (K and /K) for precise DDR timing at clock rising edges only.
Two output clocks (C and /C) for precise flight time and clock skew matching-clock and data delivered together to receiving d.
