Infineon Technologies S29GL01GS10DHI023

Overview

S29GL01GS10DHI023 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC with 3.0 V core supply, 16-bit data bus, and MIRRORBIT™ Eclipse 65 nm process technology. It delivers 90 ns random access time, 15 ns page access time, and integrated hardware ECC for single-bit error correction. Designed for embedded boot code storage in industrial control systems requiring high reliability and fast XIP execution.

For engineers reviewing the S29GL01GS10DHI023 datasheet, S29GL01GS10DHI023 pinout, S29GL01GS10DHI023 application, or S29GL01GS10DHI023 equivalent, key selection criteria include its 128-kbyte uniform sector erase architecture, 512-byte programming buffer, Versatile I/O (1.65 V–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and TSOP-56/LAA/LAE/VBU package compatibility.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A25), supporting both standard and page-mode reads. Its embedded algorithm controller (EAC) manages program/erase operations autonomously, including suspend/resume, status register polling, and RY/BY# signaling.

The internal architecture integrates dedicated erase voltage and program voltage generators, on-die ECC logic, and sector protection control registers. It supports Common Flash Interface (CFI) for host software identification and uses a 32-byte page-aligned read path where low-order address bits (A0–A3) select within-page words after initial 90 ns access.

FAQ

What is the maximum operating temperature range for S29GL01GS10DHI023?

This part is qualified to AEC-Q100 Grade 2, supporting continuous operation from –40°C to +105°C. The extended temperature range is validated per JEDEC JESD22-A108 and includes thermal cycling, high-temperature operating life, and storage tests per automotive requirements.

Does S29GL01GS10DHI023 require external level shifters when interfacing with 1.8 V logic?

No. Its Versatile I/O feature supports VIO from 1.65 V to VCC, enabling direct connection to 1.8 V FPGAs or ASICs without external level translation. VIO must be supplied independently and stabilized before VCC during power-up sequencing.

How does the 512-byte programming buffer improve firmware update efficiency?

The buffer allows up to 512 bytes to be loaded and programmed in a single embedded operation, reducing total programming time by ~70% versus single-word writes. This is especially beneficial for field updates where minimizing flash write duration improves system availability and reduces risk of power-loss corruption.

Can the Secure Silicon Region (OTP) be reprogrammed after initial programming?

No. The 1024-byte OTP array is physically one-time programmable. Once a bit is set to '0', it cannot be changed back to '1'. Two independent lock bits permanently disable further writes to each 512-byte region, ensuring cryptographic keys or calibration data remain immutable after final programming.
