This document is the IS25C01 specification, which introduces the features and characteristics of IS25C01, including low voltage operation, low power consumption, electrically erasable, SPI compatible, etc.
The IS25C01 is a 1 K‑bit (128 × 8) electrically erasable PROM that communicates via a Serial Peripheral Interface (SPI). It operates from 1.8 V to 5.5 V, supports SPI modes 0 and 3, and offers low‑power operation with standby current under 1 µA.
The device is available in 8‑pin PDIP, SOIC, and TSSOP packages, provides block write protection, an 8‑byte page write mode, and a maximum clock rate of 10 MHz. Detailed electrical characteristics, absolute maximum ratings, and ordering information are provided for both industrial and automotive temperature ranges.
| Maximum SPI clock frequency | 10 MHz |
|---|---|
| Write cycle time | ≤ 5 ms (automotive), ≤ 10 ms (industrial) |
| Endurance | 1 million cycles per byte |
| Data retention | 100 years |
| Package options | 8‑pin PDIP, 8‑pin SOIC, 8‑pin TSSOP |
The device supports a clock frequency up to 10 MHz when powered at 5 V.
The EEPROM is rated for 1 million write cycles per byte and can retain data for 100 years.
