Product details

Overview

S29GL128S11FHIV20 from Infineon is a 128 Mb (16 MB), 3.0 V core, parallel-interface MIRRORBIT™ Eclipse flash memory with ×16 data bus, 90 ns random access time, 15 ns page access time, and industrial temperature grade (–40°C to +85°C), used for firmware storage and XIP execution in embedded controllers and network boot loaders.

For engineers reviewing the S29GL128S11FHIV20 datasheet, S29GL128S11FHIV20 pinout, S29GL128S11FHIV20 application, or S29GL128S11FHIV20 equivalent, key selection factors include its 512-byte write buffer, hardware ECC (single-bit correction), uniform 128-kbyte sector erase, versatile I/O (1.65 V to VCC), and AEC-Q100 grade 3 automotive qualification.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A22), supporting both random and page-mode reads. Its embedded algorithm controller (EAC) manages program/erase operations autonomously, including suspend/resume, status register reporting, and data polling via DQ7/DQ6.

The internal architecture integrates a 65-nm MIRRORBIT™ cell array with dedicated voltage generators for programming (VPP) and erasing, plus on-die ECC logic that corrects single-bit errors during read and detects multi-bit errors - all without host CPU intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	128 Mb (16 MB), organized as 1,048,576 × 16-bit words - supports full firmware image storage for mid-tier microcontrollers.
Random access time	90 ns at VCC = VIO - enables direct XIP execution from flash with minimal CPU stall cycles.
Page access time	15 ns - accelerates sequential instruction fetch within 32-byte aligned pages.
Write buffer size	512 bytes (256 words) - reduces effective programming time by batching writes instead of single-word operations.
ECC capability	Hardware-based single-bit error correction and multi-bit error detection - ensures data integrity without software overhead.
Sector size	Uniform 128 kbyte sectors (128 sectors total) - simplifies firmware partitioning and field update management.
Endurance & retention	100,000 program/erase cycles and 20-year data retention - suitable for long-lifecycle industrial and automotive deployments.

Pinout & Package

Package: 56-pin TSOP (Type I, 400 mil width), RoHS-compliant, surface-mountable with standard reflow profile.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address inputs	23-bit word address bus (A22 = MSB); supports full 16 MB address space with no byte-select lines.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; operates at VIO (1.65 V to VCC) - enables mixed-voltage system interfacing.
CE#	Chip enable	Active-low chip select; controls device power state and enables low-standby-current mode (100 µA).
OE#	Output enable	Active-low read strobe; gates output drivers independently of CE# for multiplexed bus sharing.
WE#	Write enable	Active-low control for write operations; initiates command sequences when combined with address/data patterns.
RY/BY#	Ready/Busy indicator	Open-drain output; low during embedded program/erase, high when operation complete or ready for next command.
WP#	Write protect	Hardware sector protection enable; active-low input that locks/unlocks advanced sector protection (ASP) configuration.
RESET#	Hardware reset	Active-low asynchronous reset; forces device into reading state and clears internal status registers.

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
S29GL128S10TFI020	Same density and core voltage, but 100 ns random access (vs. 90 ns) and TSOP package only - no BGA variants.	Lacks AEC-Q100 qualification; limited to industrial-grade systems without automotive thermal or reliability requirements.	Select when cost sensitivity outweighs speed or automotive compliance needs.
MX29GL128FPTI-90G	Micron equivalent with identical 128 Mb ×16, 90 ns access, and CFI support - but no integrated ECC or OTP region.	Requires external ECC handling in host firmware; unsuitable for safety-critical or secure key storage use cases.	Choose only if host processor has robust software ECC and no secure silicon requirements.

Compared with S29GL128S10TFI020, this variant adds automotive qualification and tighter timing; versus MX29GL128FPTI-90G, it delivers on-die ECC and OTP security - making it uniquely suited for safety- and security-sensitive embedded firmware storage.

FAQ

What is the purpose of the RY/BY# pin?

The RY/BY# pin is an open-drain ready/busy indicator that signals device status during embedded operations. It asserts low during program or erase cycles and returns high when the operation completes or the device is ready for the next command. This pin enables hardware flow control without polling, reducing CPU overhead and improving system responsiveness in real-time applications.

Does S29GL128S11FHIV20 support byte-level writes?

No. S29GL128S11FHIV20 operates exclusively on a 16-bit (word) basis due to its ×16 data bus architecture and word-aligned addressing. All write operations - including single-word and buffer programming - require 16-bit data alignment and address boundaries. Byte-level access is not supported, and attempts to write misaligned data will result in undefined behavior or command failure.

How does the Versatile I/O (VIO) feature benefit system design?

The Versatile I/O feature allows the device's I/O pins to operate across a wide voltage range (1.65 V to VCC), independent of the 3.0 V core supply. This eliminates the need for external level shifters when interfacing with 1.8 V or 2.5 V host processors, simplifying PCB layout, reducing BOM count, and improving signal integrity in mixed-voltage embedded systems such as industrial gateways and automotive domain controllers.

Can the OTP region be reprogrammed after locking?

No. The 1024-byte OTP (One-Time Programmable) array consists of two lockable regions that, once locked via specific command sequences, become permanently read-only. Programming is irreversible, and lock bits cannot be cleared. This design ensures cryptographic keys, calibration constants, or regulatory identifiers remain tamper-proof throughout the device's lifetime - a requirement for medical, automotive, and industrial certification standards.
