IS25LP128-JMLE

IS25LP128-JMLE is a 128‑Mbit serial Flash memory from ISSI (IS25LP family). It stores firmware/data for microcontrollers and embedded systems.
Key points:
- Capacity and organization: 128 Mbit (16 MB); 256-byte pages; 4 KB sectors and 64 KB blocks; 3-byte addressing (up to 16 MB).
- Interface: SPI-compatible with standard SPI and high-speed Dual/Quad I/O modes (and QPI in some variants) for higher throughput.
- Voltage and packaging: Typically 2.7–3.6 V supply; JMLE suffix denotes specific package/temperature grade (check datasheet for exact details).
- Performance: Read up to ~104 MHz in SPI mode; faster in dual/quad modes; supports fast/continuous read.
- Programmable: Page program up to 256 bytes; sector/block/Chip erase.
- Features: Write protection, status/config registers, typical low-power modes and deep power-down; endurance ~100k P/E cycles; data retention ~20 years.
- Applications: Boot firmware, code storage, and general data storage in embedded systems.
Note: Exact temperature range and package details are specified by the JMLE variant—consult the datasheet for precise specs.
