UPD44165184 Overview
Description
The µPD44165084 is a 2,097,152-word by 8-bit, the µPD44165184 is a 1,048,576-word by 18-bit and the µPD44165364 is a 524,288-word by 36-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell. The µPD44165084, µPD44165184 and µPD44165364 integrates unique synchronous peripheral circuitry and a burst counter.
Key Features
- 1.8 ± 0.1 V power supply and HSTL I/O
- DLL circuitry for wide output data valid window and future frequency scaling
- Separate independent read and write data ports with concurrent transactions
- 100% bus utilization DDR READ and WRITE operation
- 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 device
- Internally self-timed write control
- Clock-stop capability with µs restart
- User programmable impedance output
