Infineon Technologies S29GL128P11FFI010

Overview

S29GL128P11FFI010 from Cypress Semiconductor is a 128 Mbit (16 MB) single-supply 3.0 V 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, includes a 32-word write buffer, secured silicon sector with electronic serial number, and CFI compliance - deployed in industrial embedded controllers requiring nonvolatile program storage and field firmware updates.

For engineers reviewing the S29GL128P11FFI010 datasheet, S29GL128P11FFI010 pinout, S29GL128P11FFI010 application, or S29GL128P11FFI010 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), WP#/ACC acceleration support, suspend/resume capability for real-time systems, and dual-package availability (64-ball Fortified BGA, 56-pin TSOP).

Technical Context

This device implements a synchronous command-set architecture with CFI-compliant interface, enabling host system compatibility across boot code, firmware, and configuration storage applications. Its internal state machine handles embedded program/erase algorithms, while RY/BY# output and status bits provide deterministic cycle completion signaling without polling overhead.

The VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing operation with 1.65–VCC I/O levels - critical for mixed-voltage SoC interfacing. Sector protection employs both persistent lock bits and password-based methods, supporting secure factory programming and field-level reconfiguration of protected regions.

FAQ

What is the function of the WP#/ACC pin on S29GL128P11FFI010?

The WP#/ACC pin serves two distinct roles: at VIL, it hardware-protects the top or bottom sector from program/erase operations; at VHH (12 V), it accelerates programming throughput by automatically enabling unlock bypass mode and reducing per-word programming time to 13.5 µs. This dual functionality supports both safety-critical write protection and high-volume manufacturing programming.

Does S29GL128P11FFI010 support byte-wide data access?

Yes, the device supports byte-wide operation via the BYTE# input: when BYTE# = VIL, only DQ0–DQ7 are active and DQ15/A-1 functions as address bit A-1 for LSB alignment. This enables compatibility with 8-bit microcontrollers and legacy bus architectures without external data-width translation logic.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region physically isolated from main array sectors. It contains an 8-word electronic serial number and supports permanent locking via factory or customer programming. Unlike standard sectors, it cannot be erased by standard commands and requires specific entry/exit command sequences, making it suitable for immutable device identity storage.

Can S29GL128P11FFI010 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, establishing 1.8 V logic thresholds for address/control inputs and 1.8 V-compatible output drive levels. This allows seamless interfacing with 1.8 V FPGAs or ASICs while maintaining 3.3 V core performance and reliability.
