AEC-Q100 Compliant SPI FeRAM Family

RAMXEED AEC-Q100 Compliant SPI Ferroelectric Random Access Memory (FeRAM) Family is a high‑reliability lineup of nonvolatile ferroelectric memories designed for demanding automotive and industrial environments. These devices operate across a wide temperature range of -40°C to +125°C, making the devices suitable for harsh conditions commonly found in vehicles and high‑temperature equipment. Built on FeRAM technology, these RAMXEED components combine the nonvolatility of traditional EEPROM or Flash with the speed and endurance of SRAM‑like memory cells, offering exceptionally high read/write endurance (up to 10¹⁴ cycles in many automotive‑grade SPI variants), and instant, delay‑free writes that support frequent data updates without performance degradation.
