Product details

Overview

S29GL128S90FAI010 from Infineon is a 128 Mb (16 MB) parallel NOR flash memory IC with 3.0 V core supply, ×16 data bus, and MIRRORBIT™ Eclipse 65 nm 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 controllers requiring reliable non-volatile program execution.

For engineers reviewing the S29GL128S90FAI010 datasheet, S29GL128S90FAI010 pinout, S29GL128S90FAI010 application, or S29GL128S90FAI010 equivalent, key selection criteria include 128-kbyte uniform sector erase, 512-byte programming buffer throughput (1.5 MBps), Versatile I/O support (1.65 V to VCC), and AEC-Q100 Grade 3 qualification for automotive control modules.

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 autonomous program/erase operations, status monitoring via RY/BY# pin or status register, and suspend/resume capability during active programming or erasing.

The flash integrates dedicated hardware ECC logic that automatically detects and corrects single-bit errors during read cycles without CPU intervention. Sector protection uses configurable volatile/non-volatile lock bits per 128-kbyte sector, and includes a separate 1024-byte OTP array with two independently lockable regions for secure configuration storage.

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128P90TFI010	Same density and timing, but uses 64-ball LAE FBGA (9 mm × 9 mm); no TSOP option	Preferred for space-constrained router PCBs where board area is prioritized over socket replacement	Select when footprint miniaturization outweighs legacy TSOP socket compatibility
MX29GL128FPTI-90G	Macronix part with identical 90 ns access, but lacks hardware ECC and OTP array	Suitable for cost-sensitive consumer gateways where ECC is handled in software	Choose only if external ECC implementation and absence of secure OTP are acceptable

Compared with S29GL128P90TFI010, this TSOP variant enables easier prototyping and field upgrades; versus MX29GL128FPTI-90G, it adds hardware ECC and OTP security-critical for medical and automotive deployments where data integrity is non-negotiable.

FAQ

What is the maximum operating voltage for VIO on S29GL128S90FAI010?

The VIO supply range is 1.65 V to VCC, with VCC rated at 2.7 V to 3.6 V. Therefore, VIO may operate up to 3.6 V when VCC is at its maximum. This Versatile I/O feature allows direct interfacing with 1.8 V or 3.3 V host processors without level shifters, simplifying board design and reducing BOM count.

Does S29GL128S90FAI010 support command-set compatibility with older CFI-compliant flashes?

Yes-it implements the Common Flash Interface (CFI) parameter table and adheres to the Intel Command Set v1.3, ensuring interoperability with existing flash-aware bootloaders and programming tools. The CFI query mode returns accurate geometry, timing, and protection information, enabling automatic detection and configuration in U-Boot and similar firmware stacks.

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

It allows up to 256 words (512 bytes) to be loaded into an internal latch before initiating a single embedded program operation, achieving 1.5 MBps effective write speed. This reduces host CPU overhead and total update time by ~7× compared to single-word programming, especially beneficial during remote OTA firmware patches in networked devices.

Can sector protection be configured dynamically during runtime?

Yes-Advanced Sector Protection (ASP) supports both volatile (cleared on power cycle) and non-volatile (persistent) lock bits per 128-kbyte sector. Configuration is performed via standard command sequences issued over the parallel bus, enabling runtime lockdown of critical boot sectors while leaving application partitions reprogrammable for field updates.
