S29GL128N10TFI010A

S29GL128N10TFI010A is a high-density parallel NOR flash memory device from Spansion (now Cypress). It provides non-volatile storage for firmware or data, with a capacity of 128 Mbit (16 MB) on an 8-bit data bus. It belongs to the 1.8‑V family, typically operating around 1.65–1.95 V, and offers asynchronous read plus erase/program operations with sector/block granularity. The device uses the standard unlock/command protocol common to NOR flash for programming and erasure, and includes typical NOR features such as write protection and data integrity options. The suffix “TFI010A” encodes packaging, temperature grade, and speed variant. For exact timings, block sizes, endurance, and the full command set, consult the official S29GL128N10TFI010A datasheet from Cypress/Spansion. Common uses include boot code storage and firmware updates in embedded systems. If you want, I can point you to the datasheet and summarize the key electrical specs.
