HIGH-SPEED 2.5V

512/256K x 18

PRELIMINARY

IDT70T633/1S

ASYNCHRONOUS DUAL-PORT

STATIC RAM

WITH 3.3V 0R 2.5V INTERFACE

◆

Features

Full hardware support of semaphore signaling between

ports on-chip

On-chip port arbitration logic

Fully asynchronous operation from either port

Separate byte controls for multiplexed bus and bus

matching compatibility

Sleep Mode Inputs on both ports

Supports JTAG features compliant to IEEE 1149.1 in

BGA-208 and BGA-256 packages

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, 144-pin Thin Quad

Flatpack and 208-ball fine pitch Ball Grid Array

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

for selected speeds

◆

True Dual-Port memory cells which allow simultaneous

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

◆

cycles

◆

Dual chip enables allow for depth expansion without

external logic

◆

IDT70T633/1 easily expands data bus width to 36 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

Busy and Interrupt Flags

◆

NOTES:

1. Address A18x is a NC for IDT70T631.

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

5670 drw 01

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

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.
