The X24164 is a CMOS 16,384 bit serial E2PROM, internally organized 2048 x 8. The X24164 features a serial interface and software protocol allowing operation on a simple two wire bus. Three device select inputs (S0–S2) allow up to eight devices to share a common two wire bus. Xicor E2PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
The X24164 is a 16,384‑bit (2048 × 8) CMOS serial EEPROM that operates from a 2.7 V to 5.5 V supply. It features low active read current (<1 mA), low active write current (<3 mA), and ultra‑low standby current (<50 pA). The device supports a two‑wire serial interface with up to eight devices sharing the bus, and provides 100 000 write cycles with data retention of 100 years.
The datasheet details the pin functions, bus protocol, write‑cycle timing, page‑write capability, and read modes (current‑address, random, sequential). Packaging options include 8‑lead DIP and 8‑lead SOIC, and ordering information specifies voltage and temperature ranges for each part variant.
