IS25WP128F-JKLE

IS25WP128F-JKLE is a 128-Mbit Serial NOR flash memory from ISSI (Integrated Silicon Solution, Inc.). It uses a SPI-compatible interface for fast code and data storage in embedded systems and typically operates from 2.7 to 3.6 V. The JKLE suffix indicates an 8‑pin package variant (with WP# and HOLD# pins for protection and bus control). Key features include fast reads, page programming (256 bytes per page), and sector/block/chip erase operations, plus Write Enable Latch, hardware write protection, and Deep Power-Down for low standby current. It’s suitable for firmware storage, boot memory, and data logging where nonvolatile storage is required. For exact timings, voltage range, temperature range, package details, and command set, consult the official IS25WP128F-JKLE datasheet.
