Memory Products Microchip’s Memory Products Memory products are at the heart of electronic devices and systems we use every day. Virtually all consumer electronics, communication, computing, automotive and medical devices require certain types of memory to store software code, data and parametric data.
Serial EEPROM Microchip offers the broadest range of Serial EEPROM devices. Our Serial EEPROMs are low-power, non-volatile memory devices with wide operating ranges, small-size and byte-alterability, making them ideal for data and program storage. Serial EEPROMs can be written more than 1 million times and retain data for over 200 years. Innovative low-power designs and extensive testing have ensured industry-leading endurance and best-in-class quality.

Serial EEPROM Packages More Memory in Less Space! Serial EEPROM devices from Microchip are available in a wide variety of tiny, innovative packages to help minimize your design, save board space and reduce cost. • WLCSP: die-sized packages, smallest form factor EEPROM package in the world • SC-70: among the smallest 5-lead EEPROM package • 5-pin SOT-23 available up to 64 Kb, 8-pin TDFN up to 1 Mb, 8-pin SOIC up to 2 Mb (I2C) Density Max.
Serial SRAM Key Benefits 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 you to use a smaller microcontroller with additional on-board RAM. Microchip’s SPI-compatible Serial SRAM devices are available in 64 Kbits, 256 Kbits, 512 Kbits and 1 Mbit options and up to 20 MHz.
NOR Flash What is SuperFlash Technology? Microchip’s SuperFlash technology is an innovative, highly reliable and versatile type of NOR Flash memory. SuperFlash technology memory is much more flexible and reliable than competing non-volatile memories. This technology utilizes a split-gate cell architecture which uses a robust thick-oxide process that requires fewer mask steps resulting in a lowercost nonvolatile memory solution with extremely fast erase time, excellent data retention and higher reliability.
