STATIC RAM

IDT70V27S/L

LEAD FINISH (SnPb) ARE IN EOL PROCESS - LAST TIME BUY EXPIRES JUNE 15, 2018

◆

Features:

Dual chip enables allow for depth expansion without

externallogic

IDT70V27 easily expands data bus width to 32 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

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

LVTTL-compatible, single 3.3V ( 0.3V) power supply

Available in 100-pin Thin Quad Flatpack (TQFP)

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

for selected speeds

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

NOTES:

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

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