HIGH-SPEED 3.3V

IDT70V659/58/57S

128/64/32K x 36

ASYNCHRONOUS DUAL-PORT

STATIC RAM

Features

◆

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed access

– Commercial: 10/12/15ns (max.)

– Industrial: 12/15ns (max.)

Dual chip enables allow for depth expansion without

external logic

IDT70V659/58/57 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

Supports JTAG features compliant to IEEE 1149.1

LVTTL-compatible, single 3.3V (±150mV) 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 208-pin Plastic Quad Flatpack, 208-ball fine

pitch Ball Grid Array, and 256-ball Ball Grid Array

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

for selected speeds

NOTES:

1. A

is a NC for IDT70V658. Also, Addresses A

and A

are NC's for IDT70V657.

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).
