HIGH-SPEED 3.3V

IDT70V7278S/L

32K x 16 BANK-SWITCHABLE

DUAL-PORTED SRAM WITH

EXTERNAL BANK SELECTS

Features

◆

32K x 16 Bank-Switchable Dual-Ported SRAM Architecture

– Four independent 8K x 16 banks

Interrupt flags with programmable masking

Dual Chip Enables allow for depth expansion without

external logic

UB and LB are available for x8 or x16 bus matching

LVTTL-compatible, single 3.3V (±5%) power supply

Available in a 100-pin Thin Quad Flatpack

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

for selected speeds

◆

– 512 kilobit of memory on chip

◆

Fast asynchronous address-to-data access time: 15ns

User-controlled input pins included for bank selects

Independent port controls with asynchronous address &

data busses

◆

Four 16-bit mailboxes available to each port for inter-

processor communications; interrupt option

NOTES:

1. The first six address pins for each port serve dual functions. When MBSEL = VIH, the pins serve as memory address inputs. When MBSEL = VIL, the pins serve as mailbox

address inputs.

2. Each bank has an input pin assigned that allows the user to toggle the assignment of that bank between the two ports. Refer to Truth Table I for more details.
