Infineon Technologies S29GL01GT10FAI020

Overview

S29GL01GT10FAI020 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC using 45-nm MIRRORBIT™ technology, operating from 2.7 V to 3.6 V with 100 ns random access time and 15 ns page access time. It features a 512-byte write buffer, internal hardware ECC for single-bit error correction, and uniform 128-KB sector erase - deployed in industrial embedded systems requiring reliable code storage and XIP execution.

For engineers reviewing the S29GL01GT10FAI020 datasheet, S29GL01GT10FAI020 pinout, S29GL01GT10FAI020 application, or S29GL01GT10FAI020 equivalent, key selection criteria include its 128-KB uniform sector architecture, Versatile I/O support (1.65 V–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and CFI-compliant interface for bootloader and firmware image storage.

Technical Context

This device implements an asynchronous parallel interface with ×8/×16 data bus configuration, supporting byte- and word-aligned addressing. Its embedded algorithm controller (EAC) manages program, erase, suspend/resume, and status monitoring without external intervention.

The internal ECC engine operates transparently during read cycles, correcting single-bit errors in real time while reporting uncorrectable multi-bit errors via status register bits. Sector protection uses both volatile (lock bits) and non-volatile (ASP) methods, with four OTP lockable regions including factory-locked SSR0 and password-protected SSR3.

FAQ

Does S29GL01GT10FAI020 support both ×8 and ×16 data bus modes?

Yes, it supports both configurations via the BYTE# pin: asserted low for ×16 mode (DQ0–DQ15 active), high for ×8 mode (DQ0–DQ7 active). Address lines remain unchanged; A0 is LSB in both modes. This flexibility allows reuse across 8-bit and 16-bit microcontroller designs without hardware modification.

What is the function of the SSR0–SSR3 OTP regions?

SSR0–SSR3 are four 2048-byte one-time-programmable arrays. SSR0 is factory-locked and used for permanent device ID or calibration data. SSR3 supports password-based read protection. SSR1 and SSR2 are user-lockable for secure boot keys or cryptographic seeds, enabling tamper-resistant firmware authentication.

How does the suspend/resume feature work during sector erase?

The device accepts a Suspend Erase command at any point during sector erase, halting the operation and returning status within 20 µs. Resume Erase restores the exact erase state. This prevents data corruption during unexpected power loss or host interrupts - critical for field-upgrade reliability in unattended systems.

Is the CFI table accessible without issuing commands?

Yes, the Common Flash Interface parameter table is mapped to fixed address offsets (0x0055, 0x0056, etc.) and readable using standard read cycles after entering CFI query mode with the 0x98 command. No special timing or voltage is required - it enables automatic driver initialization in Linux MTD and U-Boot environments.
