Infineon Technologies S29GL01GP11TFIR10

Overview

S29GL01GP11TFIR10 from Cypress Semiconductor is a 1 Gbit (128 Mbyte), 3.0 V-only, uniform-sector Page Flash memory fabricated on 90 nm MirrorBit process technology. It delivers 110 ns random access time and 25 ns page access time, features a 32-word/64-byte write buffer, supports CFI, and operates across –40°C to +85°C in industrial-grade 56-pin TSOP package. It is used in boot code storage for network routers and industrial HMIs requiring fast, reliable nonvolatile program execution.

For engineers reviewing the S29GL01GP11TFIR10 datasheet, S29GL01GP11TFIR10 pinout, S29GL01GP11TFIR10 application, or S29GL01GP11TFIR10 equivalent, key selection criteria include sector erase endurance (100,000 cycles), secured silicon sector with factory-programmable ESN, VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), and hardware reset (RESET#) with ready/busy status (RY/BY#).

Technical Context

This device implements a uniform 64 Kword (128 Kbyte) sector architecture with 1024 sectors, enabling precise firmware partitioning and field-upgrade capability. Its command-set-based operation supports autoselect, suspend/resume, unlock bypass programming, and dual protection methods-persistent bits and password-based Advanced Sector Protection.

The VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V, 2.5 V, or 3.3 V logic while maintaining full 3.0–3.6 V VCC operation. The RY/BY# output provides real-time embedded algorithm status, and WP#/ACC serves dual roles: sector write protection at VIL and VHH-accelerated programming.

FAQ

What is the function of the WP#/ACC pin on S29GL01GP11TFIR10?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.8 V), it protects the highest or lowest address sector from accidental program/erase; at VHH (11.5–12.5 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 S29GL01GP11TFIR10 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 the LSB address input (A-1). This allows 8-bit microcontroller interfacing without external data bus multiplexing, preserving full 16-bit addressing capability.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with permanent lock capability: once locked, its contents-including an 8-word factory-assigned electronic serial number-cannot be erased or rewritten. Unlike standard sectors, it supports one-time programmable identity binding for anti-counterfeiting and secure boot chain validation.

Can S29GL01GP11TFIR10 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 connection to 1.8 V logic families (e.g., ARM Cortex-M4 GPIO) without level shifters, while maintaining full 3.3 V core performance and timing specifications.
