Product details

Overview

S29GL064S70DHI040 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, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, secure silicon region with factory-programmed 16-byte serial number, and operates across –40°C to +85°C industrial temperature range in 48-lead TSOP package.

For engineers reviewing the S29GL064S70DHI040 datasheet, S29GL064S70DHI040 pinout, S29GL064S70DHI040 application, or S29GL064S70DHI040 equivalent, this device supports boot code storage, firmware updates, and secure configuration data retention in embedded control systems requiring JEDEC-compliant parallel flash with persistent sector protection and erase suspend/resume capability.

Technical Context

The S29GL064S70DHI040 implements a 16-bit parallel interface with BYTE# input enabling optional 8-bit mode, and uses Infineon's 65-nm MIRRORBIT™ process for high reliability. Its command-set compatibility with JEDEC JESD21-C ensures drop-in interoperability with legacy single-power flash designs.

Hardware-level data integrity is enforced via automatic on-the-fly ECC, low-VCC write inhibition, and dual protection mechanisms: persistent sector lock bits and password-protected sectors. The Secure Silicon Region provides a dedicated 256-byte area permanently locked after factory or customer programming.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 words × 16-bit), organized as 128 uniform 64-KB sectors
Access Time	70 ns - enables direct execution of boot code from flash in microcontroller-based systems without wait states at 14 MHz bus clock
Write Buffer Size	128 words (256 bytes) - reduces multi-word programming time by batching writes and minimizing command overhead
ECC Capability	On-die hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage
Endurance	100,000 erase/program cycles per sector - supports field firmware updates over 10+ years in industrial controllers
Data Retention	20 years typical - ensures long-term validity of calibration data and security keys in unpowered devices
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–VCC - allows flexible I/O voltage scaling independent of core supply

Pinout & Package

Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm, standard JEDEC MO-142AC footprint).

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in 16-bit mode
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# controls 8-bit vs. 16-bit operation
CE#	Chip Enable	Active-low enable for device selection; must be asserted before read/write cycles
OE#	Output Enable	Controls output drivers during read; independent of CE# and WE# timing
WE#	Write Enable	Initiates command latching or data programming; low pulse width ≥ 40 ns required
RESET#	Hardware Reset	Aborts active program/erase and returns device to reading state; tied to system reset for boot recovery
RY/BY#	Ready/Busy Output	Open-drain status signal indicating internal operation completion; used for polling-free timing control
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high-voltage = enables accelerated programming in production

Key Features

Feature	Design Value
Erase Suspend/Resume	Allows host to interrupt sector erase to read or program other sectors - critical for real-time firmware update without halting system operation
Program Suspend/Resume	Enables background programming while servicing interrupts - maintains deterministic response in automotive ECUs
Secure Silicon Region	256-byte factory- or customer-lockable area with permanent protection - stores cryptographic keys or device-specific identifiers immune to field reprogramming
Unlock Bypass Mode	Reduces multi-word programming from 4 to 2 write cycles - cuts flash update time by ~50% in bootloader implementations
Common Flash Interface (CFI)	JEDEC-compliant query table at fixed address - enables automatic flash detection and parameter negotiation in generic boot ROMs

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90DHI040	90 ns access time; otherwise identical architecture, pinout, and feature set	Lower performance margin suitable for cost-sensitive consumer gateways where 70 ns timing is not required	Select when system bus speed ≤ 11 MHz and BOM cost reduction is prioritized over worst-case timing headroom
MX29GL640EHTI-90G	Macronix part with 90 ns access, same 48-TSOP package, but lacks Secure Silicon Region and password protection	Acceptable for non-security-critical applications like basic industrial HMI where serial number and key storage are unnecessary	Choose only if ECC and persistent sector lock features are unused; verify CFI descriptor compatibility before integration

Compared with S29GL064S70DHI040, the 90 ns Infineon variant trades speed for cost, while the Macronix alternative omits security features entirely - making the original optimal for safety- or security-aware embedded systems requiring guaranteed data integrity and tamper resistance.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70DHI040?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector against accidental erase or program; when driven to 5.5 V during manufacturing, it enables accelerated programming for faster production line flashing. This dual functionality eliminates need for separate protection and programming control signals.

Does S29GL064S70DHI040 support 8-bit data bus operation?

Yes - the device supports 8-bit mode when the BYTE# input is asserted low, configuring DQ0–DQ7 as the data bus while DQ8–DQ15 become unused. This mode is fully compatible with 8-bit microcontrollers and reduces PCB routing complexity without sacrificing density or command compatibility.

How does the Secure Silicon Region differ from standard sectors?

The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked via command sequence or factory programming. Once locked, no further writes or erases are possible - unlike standard sectors, which remain reprogrammable even under persistent protection. It is accessed via specific unlock sequences and contains a factory-assigned electronic serial number.

Can S29GL064S70DHI040 be used in automotive applications?

Yes - this specific variant (DHI040 suffix) is qualified to AEC-Q100 Grade 3 (–40°C to +85°C) and supports automotive use cases including body control modules and infotainment boot storage. Its hardware reset, ECC, and sector protection features meet functional safety requirements for ASIL-B systems when integrated with appropriate system-level diagnostics.
