Product details

Overview

S29GL064S70BHI040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, internal hardware ECC for single-bit correction, and secure silicon region with factory-programmed 128-word electronic serial number. It is used in industrial embedded boot code storage where deterministic timing, sector-level erase control, and persistent firmware protection are required.

For engineers reviewing the S29GL064S70BHI040 datasheet, S29GL064S70BHI040 pinout, S29GL064S70BHI040 application, or S29GL064S70BHI040 equivalent, this device supports JEDEC-compliant command sets, byte/word configuration via BYTE# input, Erase/Program Suspend & Resume, and hardware reset-driven boot recovery in automotive and industrial control systems.

Technical Context

This device implements a 65-nm MIRRORBIT™ floating-gate architecture with hot-electron programming and hot-hole assisted erase. It features dual-mode data bus (16-bit default, configurable to 8-bit via BYTE#), separate CE#/WE#/OE# controls, and VIO-referenced I/O (1.65 V to VCC) enabling mixed-voltage system interfacing.

Hardware-level protections include low-VCC write inhibition, WP#/ACC-based first/last sector lock, RESET#-driven operation abort, and RY/BY# status signaling. The Secure Silicon Region is permanently locked post-configuration and provides tamper-resistant storage for cryptographic keys or calibration data.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 words × 16 bits), organized as uniform 32-Kword sectors
Access Time	70 ns - guarantees deterministic read latency for real-time boot code fetch
Write Buffer Size	128 words (256 bytes) - reduces multi-word programming overhead by >60% vs. single-word writes
ECC Capability	Internal hardware single-bit error correction - eliminates need for external ECC logic in host controller
Endurance	100,000 erase cycles per sector - supports field firmware updates over 10+ years of operation
Data Retention	20 years typical at 85°C - validated for industrial temperature cycling without refresh
VIO Range	1.65 V to VCC - enables direct interface with 1.8 V, 2.5 V, or 3.3 V logic without level shifters

Pinout & Package

Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm), RoHS-compliant, industrial temperature grade (–40°C to +85°C).

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in word mode
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# determines 8-bit (DQ0–DQ7) or 16-bit operation
CE#	Chip Enable	Active-low chip select; device enters standby when high, enabling power gating per access cycle
OE#	Output Enable	Active-low read strobe; controls output drivers only - does not affect internal state or timing
WE#	Write Enable	Active-low write strobe; latches command sequences and initiates internal program/erase state machines
RESET#	Hardware Reset	Asynchronous active-low reset; terminates ongoing operations and restores command interface to initial state
RY/BY#	Ready/Busy Output	Open-drain status flag; low = operation in progress, high = ready for next command
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high + elevated voltage = enables accelerated programming mode
BYTE#	Bus Width Select	Low = 16-bit mode; high = 8-bit mode (DQ0–DQ7 only active); configures data path at power-up

Key Features

Feature	Design Value
Erase Suspend / Resume	Allows host to pause sector erase to read/program other sectors - critical for real-time OS firmware updates
Program Suspend / Resume	Enables background programming while servicing interrupts - maintains deterministic response in safety-critical systems
Secure Silicon Region	128-word (256-byte) factory-lockable area with electronic serial number - meets ISO 15408 EAL4+ secure storage requirements

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90BHI040	90 ns access time, same density/package, identical command set and pinout	Lower performance tier; suitable where 70 ns timing margin is not required	Select for cost-sensitive designs with relaxed timing budgets and identical footprint compatibility
MX29GL640EHTI-90G	Macronix part; 90 ns access, 64 Mb, JEDEC-compatible but lacks Secure Silicon Region and ECC	No hardware ECC or factory-locked serial number - requires external error handling and identity management	Choose only if Secure Silicon Region and internal ECC are not mandated by system safety or certification requirements

Compared with S29GL064S90BHI040, the -70 variant delivers tighter timing for real-time boot paths; versus MX29GL640EHTI-90G, it adds certified secure storage and autonomous error correction-critical for medical, automotive, and industrial certifications.

FAQ

Does S29GL064S70BHI040 support both 8-bit and 16-bit data bus configurations?

Yes. The BYTE# input selects bus width: logic low enables full 16-bit operation (DQ0–DQ15), while logic high restricts data transfer to DQ0–DQ7 only. This configuration is sampled at power-up and remains fixed until reset, allowing seamless integration with 8-bit microcontrollers or 16-bit processors without external multiplexing.

What is the function of the WP#/ACC pin beyond write protection?

The WP#/ACC pin serves dual roles: when held low, it permanently protects the first or last sector regardless of software protection settings; when driven high with elevated voltage (typically 5.5 V), it activates accelerated programming mode, reducing pulse width and improving throughput during high-volume manufacturing programming.

How does the internal ECC operate during read cycles?

The hardware ECC engine automatically checks every 16-bit word read from the array. If a single-bit error is detected, it is corrected transparently before data is presented on DQ lines; no host intervention or additional timing overhead is required. Uncorrectable multi-bit errors trigger DQ7 toggle behavior to signal failure to the host controller.

Is the Secure Silicon Region accessible after factory locking?

No. Once the Secure Silicon Region is locked via the PPB lock bit, all read, program, and erase operations to that 128-word sector are permanently disabled. The factory-programmed 8-word electronic serial number remains readable, but no further modifications-including erasure or reprogramming-are possible, satisfying tamper-evident storage requirements for regulatory compliance.
