S29GL128N11FFA023

The S29GL128N11FFA023 is a 128-Mbit NOR flash memory device from Spansion (now Cypress). It is a parallel NOR flash with a data bus width indicated by the “N11” variant (typically x8) and operates from a 2.7–3.6 V supply. It supports standard flash operations: Read, Program, Sector/Block Erase, and Chip Erase, with a sector/block architecture suitable for firmware storage and code execution in embedded systems. It is used as non-volatile storage for embedded firmware, boot memories, and similar applications, offering random read access and deterministic erase/program cycles. The “FFA023” suffix denotes the specific package, temperature grade, and packaging variant. For exact timing, voltage ranges, sector sizes, endurance, and pinout, refer to the datasheet for S29GL128N11FFA023 and the S29GL128N11 family.

- Function: 128-Mbit parallel NOR flash memory (8-bit data bus) with address inputs A0–A23, data I/O DQ0–DQ7, and standard NOR-flash control signals (CE#, OE#, WE#, LB#, UB#, R/B#), for non-volatile storage of code/data.

Manufacturer: Spansion. Spansion is a semiconductor company that specializes in flash memory products (NOR flash). It was originally a joint venture of AMD and Fujitsu and was later acquired by Cypress Semiconductor (now part of Infineon).

Key applications include high-density, non-volatile storage for embedded systems that require execute-in-place and firmware storage: boot memory for MCUs/SoCs, firmware upgrades for consumer electronics, automotive ECUs, industrial controllers, and networking equipment; non-volatile data storage for calibration data, parameters, logs and LUTs; and general code/data storage in set-top boxes, digital cameras, printers and medical devices.
