IDT70T651/9S

HIGH-SPEED 2.5V

256/128K x 36

ASYNCHRONOUS DUAL-PORT

STATIC RAM

WITH 3.3V 0R 2.5V INTERFACE

◆

Features

◆

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed access

– Commercial: 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

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 = V

for

BUSY

output flag on Master,

M/S = V

for

BUSY

input on Slave

Busy and Interrupt Flags

◆

On-chip port arbitration logic

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

Sleep Mode Inputs on both ports

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

Green parts available, see ordering information

NOTES:

LOGIC

1. Address A

17x

is a NC for IDT70T659.

BUSY

is an input as a Slave (M/S=V

) and an output when it is a Master (M/S=V

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.
