Infineon Technologies S29GL128P11FFIV23

Overview

S29GL128P11FFIV23 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. It supports VersatileI/O™ with VIO range 1.65–VCC, write buffer programming (64 bytes), and secured silicon sector with electronic serial number for embedded boot code storage in industrial controllers.

For engineers reviewing the S29GL128P11FFIV23 datasheet, S29GL128P11FFIV23 pinout, S29GL128P11FFIV23 application, or S29GL128P11FFIV23 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function pin for factory acceleration and sector protection.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, enabling standard read, page read, and buffered program operations. Its architecture includes an internal state machine managing embedded erase and program algorithms, with RY/BY# output signaling completion and suspend/resume capability for real-time system responsiveness.

The VersatileI/O™ design decouples I/O voltage (VIO) from core supply (VCC), allowing interface compatibility with 1.8 V, 2.5 V, or 3.3 V logic while maintaining 2.7–3.6 V VCC operation. Sector protection employs both persistent lock bits and password-based methods, with WP#/ACC providing hardware-level first/last sector write protection independent of software settings.

FAQ

What is the function of the WP#/ACC pin on S29GL128P11FFIV23?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.65 V), it protects the highest or lowest sector from program/erase; at VHH (≈9 V), it accelerates programming by enabling unlock bypass mode, reducing write time per word to 13.5 µs. Internal pull-up ensures default VIH state when unconnected.

Does S29GL128P11FFIV23 support byte-wide data access?

Yes, via the BYTE# input: when pulled low, the device operates in byte mode with DQ0–DQ7 active and DQ15/A-1 repurposed as address bit A-1. This enables 8-bit microcontroller interfacing without external data bus multiplexing, preserving full 128 Mbit capacity in either configuration.

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

The Secured Silicon Sector is a dedicated 256-byte region pre-programmed with a unique 16-byte electronic serial number. Once locked (factory or user), it becomes permanently read-only and immune to bulk erase commands-providing tamper-resistant device identification essential for licensing and anti-cloning in medical and industrial systems.

Can S29GL128P11FFIV23 be used in systems with 1.8 V I/O logic?

Yes, through VersatileI/O™: set VIO = 1.8 V while maintaining VCC = 3.0–3.6 V. All address, control, and data signals conform to 1.8 V logic levels, eliminating need for external level shifters. This is confirmed in the datasheet's "VersatileIO VIO" operating mode specifications on page 2.
