IS25LP256D-JMLE

IS25LP256D-JMLE is a 256-Mbit serial flash memory from ISSI (the IS25LP256D family). It provides non-volatile storage with a small 8-pin package and SPI-compatible interface. Key points:
- Interface and addressing: Serial SPI with 24-bit addressing; supports standard SPI and enhanced modes (dual/quad I/O and QPI) for higher throughput.
- Capacity and organization: 256 Mbit (32 MB); page size typically 256 bytes; memory organized for easy code/firmware storage and data logging.
- Erase/program: Supports sector/block erase (e.g., 4 KB sectors, plus larger blocks) and page program; typical WIP/status register flow with write protection.
- Performance: Fast reads up to high MHz (commonly around 104 MHz in many ISSI parts); low-latency access via enabling Quad/IO modes.
- Power and sleep: Operates from a nominal 2.7–3.6 V supply with low-power and deep power-down modes for energy efficiency.
- Features: Status register with WIP bit, QE for Quad modes, hardware write protection options, and erase/program suspend-resume in some configurations.
- Packaging/ordering: JMLE is the specific ordering code; verify exact package (pinout) and temperature grade in the datasheet.
Use case: firmware storage, boot code, and firmware updates requiring a dense, fast, low-pin SPI flash. Always consult the datasheet for exact electrical specs and package details.
