Infineon Technologies S29GL128P10FFI020

Overview

S29GL128P10FFI020 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 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and secured silicon sector with factory-programmable 128-word serial number - deployed in industrial embedded controllers requiring nonvolatile program storage and firmware updates.

For engineers reviewing the S29GL128P10FFI020 datasheet, S29GL128P10FFI020 pinout, S29GL128P10FFI020 application, or S29GL128P10FFI020 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 both sector protection and VHH-accelerated programming.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with embedded algorithms for program and erase operations, supported by status bits (RY/BY# output) and suspend/resume capability. Its VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V/2.5 V/3.3 V logic while maintaining full 3.0 V-only operation across read/program/erase.

The memory array uses uniform 64 Kword sectors with persistent and password-based advanced sector protection, plus a dedicated 128-word secured silicon sector for immutable device identification. Command execution follows Common Flash Interface (CFI) protocol, and write buffer programming achieves 13.5 µs/word effective time when VHH is applied to WP#/ACC.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FFI020?

The WP#/ACC pin serves two distinct roles: at VIL, it protects the highest or lowest address sector from accidental program/erase; at VHH (12 V), it enables Unlock Bypass Program mode, accelerating single-word programming to 13.5 µs and eliminating command overhead. It has an internal pull-up, so it defaults to VIH (normal operation) when unconnected.

Does S29GL128P10FFI020 support true 1.8 V I/O interfacing?

Yes - with VIO set to 1.65–1.95 V and VCC at 2.7–3.6 V, the device accepts 1.8 V logic levels on all address, control, and data pins and drives compatible 1.8 V outputs. This is enabled by VersatileI/O™ architecture, verified in the datasheet's "VersatileIO VIO" operating condition tables.

How many address lines does S29GL128P10FFI020 require?

S29GL128P10FFI020 requires 23 address lines (A22–A0) to access its full 128 Mbit capacity. A22 is the most significant bit; A0 is the least significant. In byte mode, DQ15/A-1 functions as A-1 (LSB), extending addressing granularity without adding pins.

Can the secured silicon sector be reprogrammed after locking?

No - once the secured silicon sector is permanently locked (via Program Lock command), its 128-word content - including the 8-word electronic serial number - becomes read-only and cannot be altered, erased, or unlocked. Factory locking occurs during wafer test; customer locking is performed in-system using documented CFI commands.
