Serial EEPROM

Serial EEPROMs are low-power, nonvolatile memory devices with robust operating ranges, small size and byte alterability, making them ideal for data and program storage. Serial EEPROMs can be written more than one million times.

128 bit to 4 Mbit

Available in I2C, SPI, Microwire, single-wire and UNI/O® bus modes

Serial EERAM memory product

EERAM is a nonvolatile SRAM with a shadow EEPROM backup. Data is automatically backed up onto the EEPROM at power down using 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.

SPI: 64 Kbit to 1 Mbit

I2C: 4 Kbit to 64 Kbit

Available in SOIC-8, TSSOP-8, TDFN-8

Serial Flash Memory Product

Microchip's Serial Quad I/O™ (SQI™) and SPI Flash devices are manufactured with Microchip's proprietary, high-performance CMOS SuperFlash® technology, which significantly improves performance (erase any block in less than 25 ms) and reliability (100 years data retention) while lowering power consumption.

512 Kbit to 64 Mbit in 3V and multiple densities in 1.8V

SQI Flash devices: up to 104 MHz and includes advanced security features

Parallel Flash Memory Product

Microchip's multi-purpose parallel Flash memories are manufactured with Microchip's proprietary, high-performance CMOS SuperFlash technology which significantly improves performance (erase any block in less than 25 ms) and reliability (100 years data retention) while lowering power consumption.

1 Mbit to 64 Mbit in 3V and multiple densities in 5V and 1.8V

Superior read performance and security features available in Advanced MPF+

Serial SRAM memory product

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

64 Kbit to 1 Mbit

SPI, SDI and SQI bus modes

Serial NVSRAM memory product

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

512 Kbit to 1 Mbit

Battery backed

Parallel EEPROM Memory Product

Parallel EEPROM provides robust nonvolatile memory with faster read times than serial EEPROM for direct code execution and high-reliability data storage in telecommunications, avionics, military and other applications.

64 Kbit to 1 Mbit with 2.7V and 5V options

Parallel data access, similar to static RAM for read and write cycles.

OTP EPROM Memory Product

One-Time Programmable (OTP) EPROM technology with fast parallel access times provides secure, unalterable memory for excellent firmware and data protection.

256 Kbit to 8 Mbit with 5V, 3V, and battery-voltage 2.7V options

Rapid programming algorithm: 100 μs/byte

Secure Key Storage Device

CryptoAuthentication™ ICs

These secure key storage devices provide a true secure boundary to protect cryptographic keys. They help prevent counterfeiting of accessories and disposable applications and also secure your IoT device's mutual authentication.

Smart Memory Controller

The industry’s first commercially available serial memory controller, the SMC 1000 8x25G, enables CPUs and other compute-centric SoCs to utilize four times the memory channels of parallel attached DDR4 DRAM, delivering higher memory bandwidth and media independence for compute-intensive platforms with ultra-low latency.

Increased memory bandwidth

Media independent

Lower solution costs
