Product details

Overview

S29GL128S90DHI023 from Infineon is a 128 Mb (16 MB) parallel NOR flash memory with 3.0 V core supply, 16-bit data bus, and 65 nm MIRRORBIT™ Eclipse process technology. It delivers 90 ns random access time and 15 ns page access time, supports 512-byte buffer programming, internal single-bit ECC, and uniform 128 kB sector erase - deployed in automotive instrument clusters for firmware storage and boot code execution.

For engineers reviewing the S29GL128S90DHI023 datasheet, S29GL128S90DHI023 pinout, S29GL128S90DHI023 application, or S29GL128S90DHI023 equivalent, key selection criteria include industrial-plus temperature grade (–40°C to +105°C), Versatile I/O (1.65 V to VCC), OTP array support, AEC-Q100 Grade 2 qualification, and TSOP-56 package compatibility.

Technical Context

This device implements an asynchronous parallel interface with word-aligned addressing (A0–A22), requiring CE#, OE#, and WE# control signals for read/write/erase operations. Its embedded algorithm controller (EAC) manages autonomous program and sector erase sequences, while hardware ECC corrects single-bit errors on-the-fly during read cycles.

The flash array is organized into sixty-four 128 kB uniform sectors, each individually lockable via Advanced Sector Protection (ASP) using volatile or non-volatile methods. The integrated 1024-byte OTP array contains two separately lockable regions for secure configuration or calibration data storage.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	128 Mb (16 MB), organized as 2²² × 16-bit words - supports full firmware image storage for mid-tier microcontrollers.
Random access time	90 ns at VCC = VIO - enables direct XIP execution without wait states in 5 MHz bus systems.
Page access time	15 ns - allows burst reads of up to 32 bytes within same page for accelerated code fetch.
Programming buffer	512 bytes - reduces effective programming time by 4× vs. single-word writes in firmware update routines.
Erase endurance	100,000 cycles per sector - qualifies for field-updatable ECUs with 10+ years service life.
Data retention	20 years at +85°C - meets automotive long-term reliability requirements for safety-critical storage.
Operating temperature	–40°C to +105°C (Industrial Plus) - certified for under-hood and dashboard ECU deployment.
Supply voltage	VCC = 2.7 V to 3.6 V, VIO = 1.65 V to VCC - supports mixed-voltage SoC interfacing without level shifters.

Pinout & Package

Package: 56-pin Thin Small Outline Package (TSOP-I, Type I), 14 mm × 20 mm, 0.5 mm pitch, JEDEC MO-141AC compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address inputs	23-bit address bus supporting 16 MB linear space; A22 is MSB for 128 Mb density.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; operates at VIO voltage, compatible with 1.8 V/2.5 V/3.3 V host interfaces.
CE#	Chip enable	Active-low chip select; controls device power state and command latching timing window.
OE#	Output enable	Active-low read strobe; gates output drivers during asynchronous read cycles.
WE#	Write enable	Active-low write strobe; initiates program/erase command sequences when CE# and OE# are high.
RY/BY#	Ready/Busy indicator	Open-drain output signaling active embedded operation (low) or completion (high).
RESET#	Hardware reset	Active-low asynchronous reset that halts ongoing operations and returns device to read mode.
WP#	Write protect	Active-low hardware sector protection override; disables program/erase when asserted.

Key Features

Feature	Design Value
Hardware ECC	On-die single-bit error correction with automatic detection and correction during read - eliminates need for external ECC logic in safety-critical boot paths.
Versatile I/O	VIO range 1.65 V to VCC enables direct connection to 1.8 V, 2.5 V, or 3.3 V controllers without voltage translation circuitry.
OTP array	1024-byte one-time-programmable region with two independently lockable sections - stores immutable calibration data or cryptographic keys.
CFI compliance	Common Flash Interface parameter table accessible via standard command sequence - enables OS-agnostic flash driver auto-configuration.
Suspend/resume	Program and erase operations can be suspended to service high-priority reads, then resumed - improves real-time system responsiveness.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128S90TFI020	LAA Fortified BGA (13 mm × 11 mm), no TSOP option; identical electrical specs and timing.	Preferred for space-constrained PCBs where fine-pitch BGA routing is feasible.	Select when board layout prioritizes footprint over reworkability and thermal management.
MX29GL128FTHI-90G	Macronix part; 90 ns access, same density and OTP, but lacks AEC-Q100 Grade 2 certification and CFI v1.4 support.	Acceptable for industrial use only; not qualified for automotive safety-critical functions.	Choose only if AEC-Q100 compliance is not required and cost sensitivity outweighs long-term validation burden.

Compared with S29GL128S90DHI023, the TSOP-packaged Infineon variant offers superior manufacturability and thermal performance for automotive ECU designs, while the BGA alternative trades serviceability for density, and the Macronix part omits formal automotive qualification needed for Tier 1 supply chains.

FAQ

What is the maximum operating frequency supported by S29GL128S90DHI023?

The device does not operate at a clock frequency - it is an asynchronous parallel flash. Its performance is defined by access times: 90 ns random access and 15 ns page access. Bus timing is governed by CE#, OE#, and WE# setup/hold requirements, not a system clock. Maximum effective throughput is ~1.5 MBps during buffer programming.

Does S29GL128S90DHI023 support dual-plane or interleaved read operations?

No. The S29GL128S90DHI023 implements a single-plane architecture with unified address decoding. It supports only sequential page-mode reads within a 32-byte aligned page and does not provide dual-bank or interleaved access modes found in newer octal SPI or HyperBus devices.

Can the OTP array 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'. Each of the two lockable regions can be permanently locked via dedicated commands, preventing further writes to that section - irreversible at silicon level.

Is hardware reset (RESET#) required before power-up initialization?

No. Power-on reset (POR) is handled internally. Asserting RESET# is optional and used only to abort ongoing operations or force recovery from unknown states. The device enters read mode automatically after VCC stabilizes above 2.7 V, per the 86 µs POR delay specified in Section 11.3.
