Infineon Technologies S29GL512T11FHIV30

Overview

S29GL512T11FHIV30 from Infineon is a 512 Mb (64 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, hardware ECC for single-bit correction, uniform 128-KB sector erase, and supports industrial temperature range (–40°C to +85°C). It is used in boot code storage for industrial controllers requiring fast XIP execution and reliable non-volatile firmware retention.

For engineers reviewing the S29GL512T11FHIV30 datasheet, S29GL512T11FHIV30 pinout, S29GL512T11FHIV30 application, or S29GL512T11FHIV30 equivalent, key selection criteria include verified 100,000 program/erase cycles, 20-year data retention, OTP array with four lockable SSR regions, and support for both ×8 and ×16 bus configurations in TSOP and BGA packages.

Technical Context

This device implements an asynchronous parallel interface with byte/word boundary addressing and supports execute-in-place (XIP) operation, enabling direct CPU instruction fetch from flash without RAM loading. Its embedded algorithm controller (EAC) manages program, erase, and suspend/resume operations autonomously, reducing host processor overhead.

The internal hardware ECC engine performs real-time single-bit error correction during read operations, while the status register and RY/BY# pin provide concurrent status monitoring. Sector protection includes volatile and non-volatile methods per sector, plus a dedicated 2048-byte OTP array with factory-locked SSR0 and password-protected SSR3.

FAQ

What is the maximum operating temperature range supported by S29GL512T11FHIV30?

The S29GL512T11FHIV30 is rated for industrial temperature range (–40°C to +85°C) as indicated by the "I" suffix in the part number. It also supports extended (–40°C to +125°C) and automotive AEC-Q100 Grade 2 (–40°C to +105°C) variants, but this specific orderable part is qualified only for the industrial grade.

Does S29GL512T11FHIV30 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). The device automatically adapts address decoding and command interpretation based on bus width, enabling flexible integration with 8-bit or 16-bit microcontrollers.

How does the hardware ECC function during normal read operations?

The internal ECC engine operates transparently during every read access: it calculates syndrome bits on-the-fly, detects single-bit errors, corrects them in real time, and asserts no interrupt or flag unless a multi-bit error occurs. Corrected data appears on DQ lines without CPU intervention, preserving deterministic timing for XIP execution.

Can the OTP array be reprogrammed after initial programming?

No-the 2048-byte OTP array is permanently programmable only once per sector. SSR0 is factory-locked and cannot be modified; SSR1–SSR3 can be individually locked via command sequence, after which further writes to those regions are blocked. Unlocking requires hardware reset and is not supported.
