N25Q128A13E1240E

N25Q128A13E1240E is a 128‑Mbit Serial NOR Flash memory with SPI-compatible interfaces (including Quad IO modes) for embedded storage. It stores firmware or data and supports fast reads, low‑power modes, and security/protection features. Organization: 128 Mbit arranged in 16,384 pages of 256 bytes. Interfaces: SPI with standard and Quad IO modes; supports typical NOR flash voltage ranges per variant and deep power‑down. Features: page program (256 bytes), sector/block erase, write‑enable latch and write protections, status/configuration registers, and security features. Package: compact serial 8‑pin package (Vcc, GND, CS, CLK, IO0/IO1, plus WP/HOLD pins on variants). Endurance and data retention are typical of NOR flash; supports JEDEC command set and vendor‑specific opcodes (consult datasheet for exact commands). Uses: firmware storage and updates, boot code, and data logging where random access is needed. Access basics: initialize SPI, read IDs, enable writes, perform program/erase with proper addressing and timing, poll status via WIP, and manage WP/HOLD and power modes. For precise timings, voltage ranges, and opcodes, refer to the official N25Q128A13E1240E datasheet.
