Infineon Technologies S29GL128P11FFIV22

Overview

S29GL128P11FFIV22 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 110 ns random access time under regulated VCC conditions. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector with factory- or customer-programmable 128-word electronic serial number - deployed in industrial embedded boot code storage and firmware update modules.

For engineers reviewing the S29GL128P11FFIV22 datasheet, S29GL128P11FFIV22 pinout, S29GL128P11FFIV22 application, or S29GL128P11FFIV22 equivalent, key selection criteria include sector architecture uniformity, VIO voltage flexibility, WP#/ACC dual-function pin behavior, CFI compliance, and industrial temperature support (–40°C to +85°C) in 64-ball Fortified BGA packaging.

Technical Context

This device implements a synchronous/asynchronous hybrid command interface with dedicated state control logic, internal erase/program voltage generators, and hardware reset (RESET#) for deterministic recovery. Its block diagram includes X/Y decoders, sector switches, and data gating aligned to a 23-bit address bus (A22–A0), supporting both word (DQ0–DQ15) and byte (DQ0–DQ7 + DQ15/A−1) configurations via BYTE# input.

Embedded algorithms manage program/erase suspend/resume, status reporting via RY/BY#, and advanced sector protection using persistent bits or password methods. The Secured Silicon Sector resides at fixed physical location and supports one-time locking of 128-word identification space, independent of main array protection settings.

FAQ

What is the function of the WP#/ACC pin on S29GL128P11FFIV22?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.4 V), it protects the highest or lowest sector from program/erase operations; at VHH (11.5–12.5 V), it enables Unlock Bypass mode and accelerates programming throughput. It has an internal pull-up, so leaving it unconnected defaults to VIH and normal operation. This dual functionality supports both production-line programming speed and field runtime protection.

Does S29GL128P11FFIV22 support byte-wide data access?

Yes - when BYTE# is driven low (VIL), the device operates in byte mode: DQ0–DQ7 become active data lines, and DQ15/A−1 functions as the LSB address input (A−1). This allows 8-bit microcontroller or FPGA interfaces to access the full 128 Mbit array without external data-width conversion logic, maintaining full addressability and sector erase capability.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a physically separate, factory-laser-trimmed 128-word region with dedicated command sequences (0x00–0x07) for entry, programming, and locking. Unlike main array sectors, it cannot be erased via standard commands, supports one-time locking, and retains its contents even after full chip erase - making it suitable for immutable device identity, cryptographic keys, or calibration constants.

Can S29GL128P11FFIV22 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - the VersatileI/O™ architecture explicitly supports VIO = 1.65–VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, configuring all address, control, and data pins to recognize 1.8 V logic thresholds and drive 1.8 V-compatible outputs. This eliminates need for external level shifters when interfacing with 1.8 V FPGAs or ASICs, preserving signal integrity and reducing BOM count.
