Infineon Technologies S29GL128S90DHA023

Overview

S29GL128S90DHA023 from Infineon is a 128 Mb (16 MB) parallel NOR flash memory IC with 3.0 V core supply, 16-bit data bus, and 65 nm MIRRORBIT™ Eclipse process technology. It delivers 90 ns random access time, 15 ns page access time, and integrated hardware ECC for single-bit error correction - deployed in automotive instrument clusters requiring fast XIP boot code execution and robust firmware storage.

For engineers reviewing the S29GL128S90DHA023 datasheet, S29GL128S90DHA023 pinout, S29GL128S90DHA023 application, or S29GL128S90DHA023 equivalent, key selection criteria include industrial-plus temperature grade (–40°C to +105°C), uniform 128 kB sector erase, 512-byte programming buffer, Versatile I/O support (1.65 V to VCC), and AEC-Q100 Grade 2 qualification.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A22), supporting both standard read and 32-byte page-mode reads. Its embedded algorithm controller (EAC) manages program/erase operations autonomously, including suspend/resume capability and status reporting via status register, data polling, or RY/BY# pin.

The architecture integrates dedicated erase voltage and program voltage generators, on-die ECC logic, and advanced sector protection (ASP) with volatile/non-volatile lock options. The OTP array (1024 bytes, two lockable regions) enables secure boot configuration and device-specific calibration storage.

FAQ

What is the purpose of the Versatile I/O (VIO) pin on S29GL128S90DHA023?

The VIO pin supplies independent voltage to the device's I/O buffers, allowing operation with 1.65 V to VCC (up to 3.6 V). This enables direct interfacing with 1.8 V or 3.3 V host processors without external level shifters - critical for mixed-voltage automotive ECUs where core logic runs at 1.8 V while memory interface must remain robust.

Does S29GL128S90DHA023 support true random-access reads or only page-mode operation?

S29GL128S90DHA023 supports both true random-access reads (90 ns tACC) and faster page-mode reads (15 ns tPACC within 32-byte pages). Random access initiates a new page load; subsequent reads to addresses within the same page use the cached page, delivering consistent 15 ns latency - essential for efficient XIP execution of tightly packed code.

How does the on-die ECC function, and what error scenarios does it cover?

The hardware ECC corrects single-bit errors per 512-byte sector during read operations and detects double-bit errors. It operates transparently without CPU intervention and requires no external syndrome calculation. ECC coverage applies to all array reads, including CFI and status register accesses, but does not extend to OTP region reads unless explicitly enabled per datasheet configuration.

Can S29GL128S90DHA023 be used in systems requiring AEC-Q100 Grade 1 (–40°C to +125°C)?

No - S29GL128S90DHA023 is qualified for AEC-Q100 Grade 2 (–40°C to +105°C), not Grade 1. Its thermal specifications, including data retention and endurance, are validated only up to +105°C. For Grade 1 applications, Infineon offers other GL-S variants with extended characterization, but this specific TSOP-part is not rated beyond +105°C.
