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

– Four independent 8K x 16 banks

– 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

◆

Interrupt flags with programmable masking

Dual Chip Enables allow for depth expansion without

external logic

and

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)

NOTES:

1. The first six address pins for each port serve dual functions. When

MBSEL

= V

, the pins serve as memory address inputs. When

MBSEL

= V

, 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.
