IS25WP128F-JBLE-TR

IS25WP128F-JBLE-TR is a 128-Mbit serial flash memory from ISSI (Integrated Silicon Solution Inc.). It provides non-volatile storage for firmware and data in embedded systems and is SPI-interface based.
Key points:
- Capacity: 128 Mbit (16 MB) of programmable flash.
- Interface: SPI-compatible (read, fast read, write/erase operations).
- Operations: Page programming; sector/block erases (and chip erase in some modes); write-protect (WP) and hold features; low-power/deep power-down modes.
- Power/Temp: typically powered from a 2.7–3.6 V supply; suitable for standard temp ranges (consult datasheet for exact options).
- Packaging: -TR indicates Tape & Reel packaging for automated assembly; JBLE is the package code variant.
Use cases: firmware storage, boot code, and data storage in microcontroller/SoC-based designs.
For exact timings, endurance, voltage/temperature ranges, and memory organization, refer to the IS25WP128F-JBLE-TR datasheet.
