Microchip

World’s Most Reliable Memory


Microchip has been a leading supplier of memory products for over 20 years. Microchip’s broad portfolio of memory devices includes Serial EEPROM, Serial Flash, Parallel Flash, Serial SRAM and NVSRAM. Innovative low-power designs and extensive testing have ensured industry leading robustness and endurance along with best-in-class quality.


Serial EERAM

EERAM is a nonvolatile SRAM with a shadow EEPROM backup. The data is backed up on to the EEPROM automatically on power down in the presence of a small external capacitor. Unlike NVSRAM, no external battery is needed. This device combines the reliability of an EEPROM with the performance of an SRAM. EERAM offers unlimited Erase and Write cycles to the memory

  • 4Kb – 16Kb I2C
  • Available in SOIC-8 and TSSOP-8


Serial Flash

Microchip’s Serial Quad Interface (SQI™) and SPI Flash memories are manufactured with our proprietary, high-performance CMOS SuperFlash® Technology, significantly improving performance (erase any block in less than 25 ms) and reliability (100 years data retention) while lowering power consumption.

  • 512 Kb - 64 Mb in 3V and multiple densities in 1.8V
  • SQI™ Flash – Up to 104 MHz and includes advanced security features


Parallel Flash

Microchip’s multi-purpose Parallel Flash memories are manufactured with our proprietary, high-performance CMOS SuperFlash® Technology, significantly improving performance (erase any block in less than 25 ms) and reliability (100 years data retention) while lowering power consumption.

  • 1 Mb - 64 Mb in 3V and multiple densities in 5V and 1.8V
  • Superior read performance and security features available in Advanced MPF+


Serial SRAM

Serial SRAM is a standalone volatile memory that offers designers an easy and inexpensive way to add more RAM to their application. These 8-pin devices have unlimited endurance and zero write times.

  • 64 Kbit - 1 Mbit
  • SPI, SDI and SQI Bus Modes


Serial NVSRAM

Serial NVSRAM offers low cost, non-volatile RAM storage via an external battery and is ideal for applications that need to write very often to the memory.

  • 512 Kb - 1 Mb

  • Battery backed


Parallel EEPROM

Parallel EEPROMs provide robust, non-volatile memory with faster read times than Serial EEPROM for direct code execution and high-reliability data storage applications such as telecommunications, avionics, military, etc.

  • 64 Kb - 1Mb with 2.7V and 5V options
  • Parallel data access, similar to static RAM for read and write cycles.


OTP EPROM

One-Time Programmable EPROM technology with fast parallel access times provide secure, unalterable memory for excellent firmware and data protection. 
  • 256 Kb – 8Mb with 5V, 3V, and Battery-Voltage™ 2.7V options
  • Rapid Programming Algorithm - 100μs/byte


CryptoMemory

Secure EEPROMs for applications requiring comprehensive data protection, including mutual authentication between device and host. CryptoMemory provides a truly secure means of preventing product counterfeiting and piracy. 
  • 1 Kb – 256 Kb with 2.7V to 3.6V and 2.7V to 5.5V options
  • 64-bit embedded hardware encryption engine, four sets of nonreadable, 64-bit authentication keys, and four sets of nonreadable, 64-bit session encryption keys
