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
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.
- 4 Kbit to 16 Kbit
- Industry Standard I2C
- Available in SOIC-8, TSSOP-8, TDFN-8
Serial Flash
Our Serial Quad I/O™ (SQI™) and SPI Flash devices are manufactured with our 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
Our multi-purpose parallel Flash memories are manufactured with our 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+
