HIGH-SPEED 3.3V

32K x 16 DUAL-PORT

STATIC RAM

IDT70V27S/L

Features:

◆

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

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed access

◆

– Commercial:15/20/25/35/55ns(max.)

– Industrial:20/35ns (max.)

Low-power operation

◆

Busy and Interrupt Flags

On-chip port arbitration logic

– IDT70V27S

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), and 144-

pin Fine Pitch BGA (fpBGA)

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

for selected speeds

Green parts available, see ordering information

Active:500mW(typ.)

Standby: 3.3mW (typ.)

– IDT70V27L

◆

Active:500mW(typ.)

Standby:660µW(typ.)

Separate upper-byte and lower-byte control for bus

◆

matching capability

Dual chip enables allow for depth expansion without

◆

external logic

NOTES:

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

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