HIGH-SPEED

IDT707288S/L

64K x 16 BANK-SWITCHABLE

DUAL-PORTED SRAM WITH

EXTERNAL BANK SELECTS

Features

64K x 16 Bank-Switchable Dual-Ported SRAM Architecture

◆

processor communications; interrupt option

◆

– Four independent 16K 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

TTL-compatible, single 5V (±10%) power supply

Available in a 100-pin Thin Quad Flatpack (14mm x 14mm)

– 1 Megabit 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-

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.
