Automotive Memory Products

High-Quality Automotive Memory Devices

As a leading supplier of memory products for many years, we provide reliable and high-quality memory devices for all your automotive memory needs. Our portfolio of devices includes serial EEPROMs, serial SRAMs, serial and parallel Flash memories and our innovative serial EERAMs. These memory products, developed through years of research and extensive and robust testing, offer industry-leading reliability and endurance to withstand the harsh environments found in automotive applications.

Serial EEPROMs

These low-power, nonvolatile memory devices can be written more than one million times.

With their robust operating ranges, small sizes and byte alterability, serial EEPROMs are excellent for data and program storage.

  • I2C, SPI, Microwire, single-wire and UNI/O® bus interfaces
  • Densities range from 128 bit to 1 Mbit
  • AEC-Q100 Grade 0 (150°C) operation for select densities

Serial and Parallel Flash

These memory devices feature our proprietary split-gate cell architecture.

Our NOR Flash memories are manufactured with our proprietary, high-performance CMOS SuperFlash® technology, which significantly improves performance and reliability while lowering power consumption.

  • Serial SPI, Serial Dual I/O and Serial Quad I/O™ bus interfaces
  • Multi-purpose parallel Flash
  • Densities range from 4 Mbit to 64 Mbit
  • AEC-Q100 Grade 1, 2, 3 operation for select densities

Serial SRAM

These 8-pin devices have unlimited endurance and zero write times.

Serial SRAM is a standalone volatile memory that offers an easy and inexpensive way to add more RAM to your automotive application. 

  • SPI, Serial Dual I/O and Serial Quad I/O bus interfaces
  • Densities range from 64 Kbit to 1 Mbit
  • AEC-Q100 Grade 1 (125°C) operation

Serial EERAM

EERAM offers unlimited Erase and Write cycles to the memory.

EERAM is a nonvolatile SRAM with a shadow EEPROM backup. The EEPROM uses a small external capacitor to automatically back up the data when system power is lost. Unlike NVSRAM, an external battery is not needed. 

  • I2C bus interface
  • Densities range from 4 Kbit to 16 Kbit
  • AEC-Q100 Grade 1 (125°C) operation
