Infineon Technologies S29GL128P10TFI010

Overview

S29GL128P10TFI010 from Cypress Semiconductor is a 128 Mbit (16 MB) 3 V page-mode NOR Flash memory 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, 32-word write buffer, and Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial embedded controllers requiring nonvolatile program storage and firmware update capability.

For engineers reviewing the S29GL128P10TFI010 datasheet, S29GL128P10TFI010 pinout, S29GL128P10TFI010 application, or S29GL128P10TFI010 equivalent, key selection criteria include sector architecture uniformity, VIO voltage flexibility, WP#/ACC acceleration support, CFI compliance, and industrial temperature operation (–40°C to +85°C) in TSOP-56 package.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# control lines, enabling standard read, page read, and buffered program operations. Its internal state machine handles erase suspend/resume, unlock bypass programming, and advanced sector protection via persistent bits or password methods.

The memory array uses a split-gate MirrorBit cell structure enabling single-bit-per-cell storage with high endurance (100,000 erase cycles/sector) and 20-year data retention. Address decoding supports A22–A0 (23-bit addressing), and BYTE# input selects between x16 word mode (DQ0–DQ15 active) and x8 byte mode (DQ0–DQ7 active, DQ15/A-1 repurposed as LSB address).

FAQ

What is the maximum operating frequency supported for page read operations?

The S29GL128P10TFI010 does not use a clock signal; its page read performance is defined by timing parameters, not frequency. Page access time is 25 ns, enabling up to ~40 MHz effective burst throughput when reading 8-word pages continuously. The 8-word page read buffer operates asynchronously and requires no external clock source.

Does this device support both x8 and x16 data bus configurations?

Yes, the BYTE# input controls bus width: when pulled low (VIL), the device operates in x8 mode with DQ0–DQ7 active and DQ15/A-1 repurposed as address bit A-1; when high (VIH), it operates in x16 mode with full DQ0–DQ15 data path. This dual-mode capability allows seamless integration with 8-bit and 16-bit microcontrollers without external glue logic.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is programmed using standard command sequences (e.g., unlock, program, confirm) via the DQ bus, then permanently locked either at the factory or by the end user using the "Lock Secured Silicon Sector" command. Once locked, the 128-word region becomes read-only and immune to erase or program commands - verified by status bit polling and CFI query.

Can WP#/ACC be used simultaneously for sector protection and programming acceleration?

No - WP#/ACC serves two mutually exclusive functions: at VIL, it protects the top or bottom sector; at VHH (12 V), it enables accelerated programming and auto-unlock bypass. These modes cannot operate concurrently. The pin must be driven to VIH (3.0–3.6 V) during normal read operations and VIL or VHH only during protection or programming phases, respectively.
