HIGH-SPEED 3.3V

8/4K x 18 DUAL-PORT

8/4K x 16 DUAL-PORT

STATIC RAM

IDT70V35/34S/L

IDT70V25/24S/L

Features

◆

Separate upper-byte and lower-byte control for multiplexed

bus compatibility

◆

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

◆

IDT70V35/34 (IDT70V25/24) easily expands data bus width

to 36 bits (32 bits) or more using the Master/Slave select

when cascading more than one device

◆

High-speed access

IDT70V35/34

– Commercial:15/20/25ns(max.)

– Industrial:20ns

M/S = VIH for BUSY output flag on Master

M/S = VIL for BUSY input on Slave

IDT70V25

◆

BUSY and Interrupt Flag

– Commercial:15/20/25/35/55ns(max.)

– Industrial:20/25ns

IDT70V24

between ports

– Commercial:15/20/25/35/55ns(max.)

– Industrial:20ns

◆

Fully asynchronous operation from either port

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

Available in a 100-pin TQFP (IDT70V35/24) & (IDT70V25/24),

86-pin PGA (IDT70V25/24) and 84-pin PLCC (IDT70V25/24)

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

for selected speeds

1. A12 is a NC for IDT70V34 and for IDT70V24.

2. (MASTER): BUSY is output; (SLAVE): BUSY is input.

3. BUSY outputs and INT outputs are non-tri-stated push-pull.

4. I/O0x - I/O7x for IDT70V25/24.

5. I/O8x - I/O15x for IDT70V25/24.
