Infineon Technologies S29GL01GS11TFIV20

Overview

S29GL01GS11TFIV20 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC with 16-bit data bus, fabricated on 65 nm MIRRORBIT™ Eclipse process. It operates from a single 2.7–3.6 V supply, delivers 90 ns random access and 15 ns page access, and integrates hardware ECC for single-bit error correction-used in boot code storage and firmware update storage for industrial microcontroller systems.

For engineers reviewing the S29GL01GS11TFIV20 datasheet, S29GL01GS11TFIV20 pinout, S29GL01GS11TFIV20 application, or S29GL01GS11TFIV20 equivalent, key selection criteria include its 128-kbyte uniform sector erase granularity, 512-byte write buffer, Versatile I/O (1.65–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and CFI-compliant interface for host BIOS/ROM loader compatibility.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A25), supporting both standard read and 32-byte page-mode reads. Its embedded algorithm controller (EAC) manages all program/erase operations-including suspend/resume-and enforces automatic ECC on every write/erase cycle.

The flash array is organized into uniform 128-kbyte sectors, each independently erasable and protected via Advanced Sector Protection (ASP) with volatile/non-volatile lock options. The integrated 1024-byte OTP array includes two lockable regions for secure configuration or calibration data storage.

FAQ

Is S29GL01GS11TFIV20 pin-compatible with earlier S29GLxxxS generations?

Yes, it shares identical 64-ball LAE BGA pinout and command set with other GL-S family members (e.g., S29GL512S, S29GL256S), enabling drop-in density upgrades without PCB revision-provided address bus width (A25) and timing margins are verified for the target system.

Does this device support execute-in-place (XIP) operation?

Yes, its fast 90 ns random access and asynchronous parallel interface enable true XIP execution directly from flash memory, eliminating the need to copy code to RAM-commonly used in automotive bootloaders and real-time OS kernels where deterministic startup timing is required.

What is the function of the Versatile I/O (VIO) feature?

Versatile I/O allows independent VIO supply (1.65 V to VCC) for the DQ[15:0] bus, decoupling I/O voltage from core VCC. This enables seamless interfacing with mixed-voltage SoCs (e.g., 1.8 V I/O with 3.3 V core) without external level shifters-reducing BOM cost and board space.

How does the hardware ECC operate during normal read/write cycles?

Hardware ECC runs transparently on every read and write: during reads, single-bit errors are corrected in real time before data reaches the bus; during writes, ECC bits are automatically calculated and stored alongside data. No firmware intervention or additional latency is required-ensuring data integrity across 100,000 program/erase cycles.
