256 Mbit parallel NOR flash for code and data storage
The Infineon (formerly Cypress) S29GL256P10FFI022 is a 256 Mbit parallel NOR flash memory from the GL-P series, organized as 32M x 8 bits. Typical applications include industrial controllers, networking equipment, and telecom infrastructure where the parallel bus simplifies integration with legacy MCUs or FPGAs that lack a serial-flash controller.
100 ns access — timing margin for the parallel bus
The 100 ns access time sets the window for the MCU or FPGA to latch valid data after asserting the address and chip-enable. The page-program write cycle also runs at 100 ns per word.
The GL-P series has been a workhorse in the Infineon NOR flash portfolio, and active status suggests continued manufacturing support for the foreseeable future.
64-ball FBGA — footprint and rework considerations
Packaged in a 64-ball FBGA (Fine-pitch Ball Grid Array), this part uses a surface-mount footprint that requires standard BGA reflow profiling. The Tape & Reel (TR) packaging suits automated pick-and-place assembly. For rework or replacement in the field, the BGA package calls for a hot-air station with a nozzle sized to the 64-ball array and a pre-bake step per MSL requirements — the FBGA construction is moisture-sensitive, so the floor-life window after opening the sealed bag must be respected to avoid popcorning during reflow.
