概要
Description
IS25LP256D-JMLE is ISSI’s 256‑Mbit serial NOR flash memory in the IS25LP256D family. It provides non-volatile storage controlled over a SPI-compatible interface and is used to store firmware, data, or code that can be executed in place or shadowed.
Key points:
- Capacity: 256 Mbit (32 MB).
- Interface: SPI with options for fast/read modes; supports dual- and quad‑I/O reads for higher throughput (device/layout dependent).
- Operations: standard read, fast read, page program (typically 256 bytes), sector/block erases (e.g., 4 KB, 32 KB, 64 KB) and chip erase.
- Power: low-power modes (power-down/standby) for energy efficiency.
- Volatility/variety: operates over a defined voltage range; available in packages and temperature grades (including industrial variants) per the -MLE suffix.
- Use cases: firmware storage, bootloaders, code shadowing, data logging in embedded systems.
Note: For exact specs (voltage range, max read/write speeds, package options, temperature range) consult the official ISSI IS25LP256D-JMLE datasheet.
