Description
IS25LP512M-RHLE is a 512-Mbit serial NOR flash memory from ISSI used for code and data storage. It provides high-density nonvolatile storage with an SPI interface and supports high-speed modes (single, dual I/O, quad I/O, and QPI where available) for faster reads.
Key points:
- Capacity and interface: 512 Mbit, SPI with multi‑I/O options
- Voltage and performance: 2.7–3.6 V supply; fast reads (up to high-speed clocks in supported modes)
- Memory organization: 4 KB sectors, 64 KB blocks; 256-byte page program; whole-chip erase
- Endurance and retention: typical 100k–1M erase cycles; 20-year data retention
- Power and security: power-down modes; write protection, status register, and security features
- Packaging note: RHLE suffix denotes a specific package/temperature grade; check the datasheet for exact package and timing
Typical applications: firmware/code storage and boot memory for microcontrollers and embedded systems.
