Do you need a simple, inexpensive way to add RAM to

your application? Microchip offers external RAM where

you need it.

Microchip’s new serial SRAM family provides a way to easily and

inexpensively add external RAM to almost any application. These serial

SRAM. And, they allow designers to use a smaller microcontroller rather than

moving to a larger microcontroller just to get more on-board RAM.
