The X25080 is a CMOS 8192-bit serial E2PROM, internally organized as 1K x 8. The X25080 features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple three-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus. The X25080 also features two additional inputs that provide the end user with added flexibility.
The X25080 is a CMOS 1 K × 8‑bit serial E2PROM that communicates via a three‑wire SPI bus. It offers a 2 MHz clock rate, low standby current (<1 µA) and active current (<5 mA), and supports block‑lock protection for ¼, ½ or the entire memory array. The device includes HOLD and WP pins for pause and write‑protect functions, and uses Xicor’s Direct Write™ cell for high reliability.
The part is supplied in 8‑lead PDIP, 8‑lead SOIC and 14‑lead TSSOP packages. It operates from 2.7 V to 5.5 V with recommended commercial temperature range of 0 °C to +70 °C (absolute maximum –65 °C to +135 °C). Endurance is rated at 100 000 write cycles with 100‑year data retention, and it provides 2000 V ESD protection on all pins.
