IS25LP512M-RMLE-TY

IS25LP512M-RMLE-TY is a 512‑Mbit Serial NOR Flash memory from ISSI (IS25LP family). It uses a SPI-compatible interface with support for single, dual, and quad I/O modes to boost throughput. The device stores firmware and data up to 64 MB and provides standard NOR flash operations: page program, sector erase, and block erase, plus protection and security features. It supports fast read and low-power modes, including deep power-down. Typical supply voltage is 2.7–3.6 V. The TY suffix indicates Tape-and-Reel packaging; RMLE denotes a specific package/temperature variant in ISSI’s naming. It’s an 8‑pin device, suitable for boot memory, firmware storage, and other embedded‑system applications. For exact timing, endurance, block sizes, addressing, and command set details (READ, FAST READ, PP, ERASE, WRR, RESET, etc.), consult the latest ISSI datasheet and packaging documentation.
