概述
Description
IS25LP128F-RMLA3 is a high-density serial NOR flash memory from ISSI (128 Mbit) intended for embedded systems. It stores firmware and data and is accessed via a serial peripheral interface (SPI), with support for standard SPI as well as high-speed dual/quad I/O modes to boost throughput. Key features include 2.7–3.6 V operation, 256-byte page programming, sector (and block) erase, fast read commands, and typical protection/write-enable mechanisms plus deep power‑down for low current when idle. It supports JEDEC ID reads and security features for device protection. Typical uses are boot code storage and application firmware, plus data logging in microcontroller-based designs. The -RMLA3 suffix denotes the specific packaging/variant (lead-free/RoHS-compliant and a particular package code and temperature range); for exact package pins, timing, and command set, consult the ISSI datasheet.
