Infineon Technologies S29GL128P10FFI012

Overview

S29GL128P10FFI012 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword 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, includes a 32-word write buffer for accelerated multi-word programming, and integrates Secured Silicon Sector with factory- or customer-programmable 128-word serial number - deployed in industrial embedded controllers requiring reliable nonvolatile storage with sector-level protection.

For engineers reviewing the S29GL128P10FFI012 datasheet, S29GL128P10FFI012 pinout, S29GL128P10FFI012 application, or S29GL128P10FFI012 equivalent, key selection criteria include its 64-ball Fortified BGA (LAA064) package, industrial temperature range (–40°C to +85°C), WP#/ACC acceleration input, CFI compliance, and dual-sector protection modes (Persistent/Password).

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# control lines, enabling standard NOR Flash command-set execution including autoselect, program suspend/resume, and advanced sector protection. Its architecture separates address decoding (A22–A0), data I/O (DQ15/A-1 through DQ0), and power domains (VCC, VIO, VSS) to support mixed-voltage system integration.

The internal state machine manages embedded erase and program algorithms with real-time status reporting via RY/BY# output and status bits. The Secured Silicon Sector resides at fixed physical address space and operates independently of main array protection settings, supporting permanent device identification and secure boot initialization.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FFI012?

The WP#/ACC pin serves dual roles: at VIL, it protects the highest or lowest sector from program/erase; at VHH (12 V), it enables Unlock Bypass Program mode, reducing single-word programming time from 60 µs to 13.5 µs and accelerating production-line flashing. Internal pull-up ensures default VIH state when unconnected.

Does S29GL128P10FFI012 support byte-wide data access?

Yes - when BYTE# is driven low, the device enters byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as address bit A-1 (LSB). This enables compatibility with 8-bit microcontrollers and legacy bus architectures without external data-width translation.

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 independent lock control. Unlike main array sectors, it cannot be erased by standard commands and retains data even after full chip erase. Its 8-word electronic serial number is permanently programmable and lockable either at factory or by end-user.

Can S29GL128P10FFI012 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, allowing direct interfacing with 1.8 V FPGAs or ASICs while maintaining full 3.3 V core performance, including 90 ns random access and 25 ns page access times.
