Microchip – Serial SRAM Memory Family
Microchip’s serial SRAM family provides a way to easily and inexpensively add external RAM to almost any application. These serial
devices use less power and fewer I/O connections than traditional parallel SRAM. And, they allow designers to use a smaller microcontroller rather than moving to a larger microcontroller just to get more on-board RAM.
Quickly and easily add external SRAM
- 8 and 128 Kbyte options
- Great for scratchpad, buffering and math-intensive applications
- Add functionality to your current design
Add features to your current MCUs and get to market faster
- Familiar 4-pin SPI interface
- Serial bus requires only 4 microcontroller I/O pins
- No need to buy a large microcontroller just for the RAM
- Cost-reduce your current design
Get high-speed SRAM
- 20 MHz clock speed
- Unlimited writes to the array (with no wear out)
- Low standby and operating currents
- Fast writes with zero latency
- Write entire 32 Kbyte chip in 13 ms with one command
