HIGH-SPEED 3.3V 256K x 18

ASYNCHRONOUS DUAL-PORT

STATIC RAM

◆

IDT70V631S

Features

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed access

– Commercial: 10/12/15ns (max.)

– Industrial: 12ns (max.)

Dual chip enables allow for depth expansion without

external logic

IDT70V631 easily expands data bus width to 36 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

– Due to limited pin count, JTAG is not supported on the

128-pin TQFP package.

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 128-pin Thin 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:

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).
