Infineon Technologies S29GL01GS11FHB020

Overview

S29GL01GS11FHB020 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 time and 15 ns page access time, and integrates hardware ECC for single-bit error correction. It is used in boot code storage for industrial microcontrollers requiring fast XIP execution and reliable non-volatile program retention.

For engineers reviewing the S29GL01GS11FHB020 datasheet, S29GL01GS11FHB020 pinout, S29GL01GS11FHB020 application, or S29GL01GS11FHB020 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 command set for firmware update compatibility.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A25), supports both standard and page-mode reads, and uses embedded algorithms for sector erase and buffered programming. Its internal state machine handles command execution, status reporting via RY/BY# pin or status register, and automatic ECC generation/correction during read.

The GL-S architecture separates address decoding (X/Y decoders), voltage generation (for erase/program), and sector protection logic, enabling independent suspend/resume of program and erase operations. Sector-level ASP allows volatile/non-volatile locking per 128-kbyte block, while the 1024-byte OTP array provides secure boot configuration storage.

FAQ

Does S29GL01GS11FHB020 support both 1.8 V and 3.3 V I/O interfaces?

Yes. Its Versatile I/O feature supports VIO from 1.65 V to VCC, allowing direct connection to 1.8 V or 3.3 V host processors without level shifters. When VCC is 3.0 V, VIO may be independently set to 1.8 V or 3.0 V, and all input thresholds and output drive strengths adapt accordingly per datasheet Section 8.3.

What is the function of the RY/BY# pin during programming?

RY/BY# is an open-drain ready/busy indicator that goes low during embedded program or erase operations and returns high when the operation completes or is suspended. It provides hardware handshaking for timing-critical hosts and can be polled alongside the status register for precise operation status without continuous command polling.

Can the 1024-byte OTP array be reprogrammed after initial programming?

No. The OTP array is physically one-time programmable: each bit can be written from '1' to '0' only once. Two independent lock bits permanently disable further writes to each 512-byte region. Once locked, no command or voltage sequence can unlock or rewrite the region - ensuring cryptographic key or calibration data immutability.

How does hardware ECC interact with the status register during read operations?

During every read, internal ECC logic checks the retrieved 16-bit word plus associated parity bits. If a single-bit error is detected, it is corrected on-the-fly and the corrected data is output; the status register's ECC bit (bit 6) is set to '1' to indicate correction occurred. No interrupt is generated - correction is transparent and does not stall the read cycle.
