UPD44325362 Datasheet 36m-bit Qdrii Sram

Manufacturer: NEC (now Renesas Electronics)

Overview: .. PRELIMINARY DATA SHEET MOS INTEGRATED CIRCUIT µPD44325082, 44325092, 44325182, 44325362 36M-BIT QDRTMII SRAM 2-WORD BURST.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The µPD44325082 is a 4,194,304-word by 8-bit, the µPD44325092 is a 4,194,304-word by 9-bit, the µPD44325182 is a 2,097,152-word by 18-bit and the µPD44325362 is a 1,048,576-word by 36-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.

The µPD44325082, µPD44325092, µPD44325182 and µPD44325362 integrate 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.

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.
  • Two-tick burst for low DDR transaction size.
  • 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.
