HIGH-SPEED 2.5V

PRELIMINARY

IDT70T651/9S

256/128K x 36

ASYNCHRONOUS DUAL-PORT

STATIC RAM

WITH 3.3V 0R 2.5V INTERFACE

◆

Busy and Interrupt Flags

On-chip port arbitration logic

Features

◆

True Dual-Port memory cells which allow simultaneous

◆

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

Separate byte controls for multiplexed bus and bus

matching compatibility

access of the same memory location

High-speed access

◆

– Commercial:8/10/12/15ns(max.)

– Industrial: 10/12ns(max.)

◆

RapidWrite Mode simplifies high-speed consecutive write

◆

Sleep Mode Inputs on both ports

cycles

◆

Supports JTAG features compliant to IEEE 1149.1

Single 2.5V (±100mV) power supply for core

LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV)

power supply for I/Os and control signals on each port

Available in a 256-ball Ball Grid Array, 208-pin Plastic Quad

Flatpack and 208-ball fine pitch Ball Grid Array.

Industrial temperature range (–40°C to +85°C) is available

for selected speeds

Dual chip enables allow for depth expansion without

external logic

◆

IDT70T651/9 easily expands data bus width to 72 bits or

more using the Master/Slave select when cascading more

than one device

◆

M/S = VIH for BUSY output flag on Master,

M/S = VIL for BUSY input on Slave

NOTES:

1. Address A17x is a NC for IDT70T659.

2. BUSY is an input as a Slave (M/S=VIL) and an output when it is a Master (M/S=VIH).

3. BUSY and INT are non-tri-state totem-pole outputs (push-pull).

4869 drw 01

4. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. OPTx, INTx, M/S and the sleep

mode pins themselves (ZZx) are not affected during sleep mode.
