Product details

Overview

S29GL128S90TFI023 from Infineon is a 128 Mb (16 MB) parallel NOR flash memory IC with 3.0 V core supply, 16-bit 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 control systems requiring high reliability and fast XIP execution.

For engineers reviewing the S29GL128S90TFI023 datasheet, S29GL128S90TFI023 pinout, S29GL128S90TFI023 application, or S29GL128S90TFI023 equivalent, key selection criteria include 128-kbyte uniform sector erase, 512-byte write buffer throughput (1.5 MBps), Versatile I/O support (1.65–3.6 V), and AEC-Q100 Grade 3 qualification for automotive use cases.

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 internal architecture includes dedicated erase voltage and program voltage generators, on-die ECC logic for real-time single-bit correction, and a configurable sector protection scheme with volatile/non-volatile lock bits. The CFI parameter table enables host software to auto-configure timing and command sets at initialization.

Key Specifications

RY/BY#	Ready/Busy indicator	Open-drain status output; low during embedded operations, used for hardware polling
WP#	Write protect	Hardware sector lock override; disables program/erase when asserted low
VCC	Core supply	3.0 V ±10% supply (2.7–3.6 V); powers core logic, EAC, and voltage generators
VIO	I/O supply	Independent I/O rail (1.65–3.6 V); decouples interface voltage from core for mixed-voltage SoC interfacing

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128P90TFI020	Same density and timing, but uses older 90 nm process; lacks Versatile I/O (VIO fixed to VCC)	No independent I/O rail - incompatible with mixed-voltage SoCs requiring 1.8 V I/O at 3.3 V core	Select only if legacy board compatibility or cost sensitivity outweighs I/O flexibility needs
MX29GL128FPTI-90G	Macronix part with identical 128 Mb density, 90 ns tACC, and 512-byte buffer; no integrated ECC	Requires external ECC handling in host firmware or companion controller	Choose when system already implements software ECC or when BOM consolidation favors single-supplier sourcing

Compared with S29GL128P90TFI020 and MX29GL128FPTI-90G, the S29GL128S90TFI023 uniquely combines Versatile I/O, on-die ECC, and AEC-Q100 Grade 3 qualification - making it optimal for new designs demanding mixed-voltage interoperability and functional safety compliance without firmware overhead.

FAQ

Does S29GL128S90TFI023 support both 3.3 V and 1.8 V I/O interfaces?

Yes. Its Versatile I/O feature allows VIO to operate independently from VCC across 1.65 V to 3.6 V. When interfaced with a 1.8 V SoC, VIO is set to 1.8 V while VCC remains at 3.0 V - enabling direct connection without level shifters. This is confirmed in Section 8.3 of the datasheet and validated in Infineon's application note AN229227.

What is the function of the STB pin on S29GL128S90TFI023?

The STB (Strobe) pin is not present on the S29GL128S90TFI023. It appears only on earlier GL-P series devices. This part uses standard CE#/OE#/WE# control signals and has no STB pin - verified in the "Signal Descriptions" section (page 72) and pinout diagrams (pages 104–109) of the official datasheet 001-98285 Rev. *U.

Can the OTP array be programmed after initial device power-up?

Yes. The 1024-byte OTP (One-Time Programmable) array is accessible via standard CFI commands and can be programmed in-system using the same command set as main array programming. Each of its two lockable regions may be permanently locked after programming - detailed in Section 3.3 and Table 3-1 of the datasheet.

Is the 15 ns page access time guaranteed across the full industrial temperature range?

Yes. The 15 ns page access time (tPACC) is specified over the full –40°C to +85°C industrial temperature range and 2.7–3.6 V VCC, as stated in the "Performance Summary" table (page 2) and confirmed in AC characteristics Table 11-3 (page 93) of datasheet 001-98285 Rev. *U.
