DATA SHEET

MOS INTEGRATED CIRCUIT

PD464318AL, 464336AL

4M-BIT Bi-CMOS SYNCHRONOUS FAST STATIC RAM

256K-WORD BY 18-BIT / 128K-WORD BY 36-BIT

HSTL INTERFACE / REGISTER-REGISTER / LATE WRITE

Description

The µPD464318AL is a 262,144 words by 18 bits, and the µPD464336AL is a 131,072 words by 36 bits

synchronous static RAM fabricated with advanced Bi-CMOS technology using N-channel memory cell.

This technology and unique peripheral circuits make the µPD464318AL and µPD464336AL a high-speed device.

The µPD464318AL and µPD464336AL are suitable for applications which require high-speed, low voltage, high-

density memory and wide bit configuration, such as cache and buffer memory.

These are packaged in a 119-pin plastic BGA (Ball Grid Array).

Features

• Fully synchronous operation

• HSTL Input / Output levels

• Fast clock access time : 2.0 ns / 250 MHz, 2.3 ns / 225 MHz, 2.5 ns / 200 MHz

• Asynchronous output enable control : /G

• Byte write control : /SBa (DQa1-9), /SBb (DQb1-9), /SBc (DQc1-9), /SBd (DQd1-9)

• Common I/O using three-state outputs

• Internally self-timed write cycle

• Late write with 1 dead cycle between Read-Write

• User-configurable outputs :

Controlled impedance outputs or push-pull outputs

• Boundary scan (JTAG) IEEE 1149.1 compatible

• 3.3 V (Chip) / 1.5V (I/O) supply

• 119 bump BGA package, 1.27 mm pitch, 14 mm x 22 mm

• Sleep mode : ZZ(Enables sleep mode, active high)
