Infineon Technologies S29GL01GS11FHIV10

Overview

S29GL01GS11FHIV10 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC with 16-bit data bus, 3.0 V core supply (2.7–3.6 V), and industrial temperature grade (–40°C to +85°C). It features 65 nm MIRRORBIT™ Eclipse technology, 15 ns page access time, 90 ns random access time, and integrated hardware ECC for single-bit error correction - deployed in boot code storage for industrial HMIs requiring fast XIP execution and long-term data retention.

For engineers reviewing the S29GL01GS11FHIV10 datasheet, S29GL01GS11FHIV10 pinout, S29GL01GS11FHIV10 application, or S29GL01GS11FHIV10 equivalent, this device supports asynchronous read, sector erase, suspend/resume operations, OTP array programming, and CFI-compliant interface - critical for firmware update reliability and deterministic boot timing in safety-aware embedded systems.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A25), 32-byte page read capability, and hardware-managed ECC that corrects single-bit errors on-the-fly during read. Its embedded algorithm controller handles full-sector erase (128 kB), buffer programming (up to 512 bytes), and status monitoring via RY/BY# pin or status register polling.

The Versatile I/O feature enables independent VIO supply (1.65 V to VCC), allowing direct interfacing with 1.8 V or 3.3 V controllers without level shifters. Sector protection includes volatile/non-volatile lock bits per 128 kB sector and a dedicated 1024-byte OTP array with two lockable regions for secure configuration storage.

FAQ

Does S29GL01GS11FHIV10 support hardware reset recovery after power loss during programming?

Yes. The device integrates power-loss detection circuitry that automatically aborts incomplete program/erase operations and restores valid sector states upon power-up. This is enforced by the embedded algorithm controller and requires no host intervention, ensuring data consistency even after unexpected brownouts in industrial settings.

Can the OTP array be reprogrammed after initial lock?

No. Once either of the two OTP lock bits is set (via specific command sequence), that 512-byte region becomes permanently read-only. The lock is irreversible and enforced by on-die fuses; no unlock command exists in the command set, making it suitable for immutable security keys and calibration constants.

What is the minimum VIO voltage supported during read operations?

The minimum VIO voltage is 1.65 V, verified across the full industrial temperature range. At this level, all 16-bit DQ lines meet setup/hold timing and drive strength specs per datasheet Table 10.5, enabling direct interface with 1.8 V FPGAs and microcontrollers without level translation.

How does the Versatile I/O feature affect timing specifications?

When VIO ≠ VCC (e.g., VIO = 1.8 V, VCC = 3.0 V), AC timing degrades slightly: random access increases to 100 ns and page access to 25 ns. These values are fully characterized and guaranteed - no derating or additional timing margins are needed beyond those specified in the "VersatileIO" column of the Performance Summary table.
