Product details

Overview

S29GL064S70FHI040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, and 65-nm MIRRORBIT™ process technology. It features 128 uniform 64-KB sectors, on-chip ECC for single-bit error correction, and secure silicon region with factory-programmed 16-byte electronic serial number. Used in industrial embedded boot storage where deterministic timing and data integrity are critical.

For engineers reviewing the S29GL064S70FHI040 datasheet, S29GL064S70FHI040 pinout, S29GL064S70FHI040 application, or S29GL064S70FHI040 equivalent, this device supports JEDEC-compliant command sets, hardware reset (RESET#), ready/busy signaling (RY/BY#), and flexible sector protection including password-locked and persistent modes - all essential for reliable firmware storage in safety-aware systems.

Technical Context

The S29GL064S70FHI040 implements a parallel 16-bit wide interface with BYTE# input enabling optional 8-bit mode. Its architecture includes dedicated command latching logic, internal address/data registers for erase/program operations, and automatic hardware ECC that corrects single-bit errors during read without host intervention.

It supports full chip erase, sector erase (64-KB uniform), and advanced suspend/resume functionality for both program and erase cycles - allowing concurrent read access to unprotected sectors while background operations execute. The device uses hot-electron injection for programming and hot-hole assisted erase, with VIO-controlled I/O levels (1.65 V to VCC) ensuring compatibility across mixed-voltage system designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (8 MB), organized as 4,194,304 × 16-bit words - sufficient for full bootloader + configuration + firmware image in space-constrained industrial controllers.
Access Time	70 ns at VCC = 2.7–3.6 V - enables direct execution from flash (XIP) in real-time microcontroller applications without wait states.
Erase Endurance	100,000 cycles per sector - supports field firmware updates over 10+ years in deployed equipment with infrequent but critical reprogramming.
Data Retention	20 years typical at 85°C - guarantees long-term integrity of boot code and calibration data in unattended industrial gateways.
ECC Capability	Internal hardware single-bit error correction - eliminates need for external error-handling logic or software overhead in safety-critical boot paths.
Secure Silicon Region	128-word (256-byte) factory-locked area with 8-word serial number - provides immutable device identity for secure boot key binding and anti-cloning.
Operating Temperature	–40°C to +105°C (Industrial Plus grade) - qualified for under-hood automotive ECUs and high-temperature factory automation modules.

Pinout & Package

Package: 48-lead TSOP (Thin Small Outline Package), 12 mm × 20 mm × 1.2 mm body, standard JEDEC MO-142AC footprint. Pin-compatible with legacy S29GL064N and S29GL064P devices in same package variant.

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 or byte lane in 8-bit mode when BYTE# = LOW.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; direction controlled by WE# and OE#; VIO-referenced I/O levels (1.65–VCC) enable mixed-voltage interfacing.
CE#	Chip Enable	Active-low chip select; device enters low-power standby when CE# HIGH and RESET# HIGH - critical for power-gated subsystems.
OE#	Output Enable	Active-low output control; allows shared data bus arbitration without tristate conflicts in multi-device memory maps.
WE#	Write Enable	Active-low write strobe; latches command sequences and initiates internal program/erase state machines upon valid address/data setup.
RESET#	Hardware Reset	Asynchronous active-low reset; terminates ongoing operations and returns device to read mode - synchronizes boot sequence with system power-on reset.
RY/BY#	Ready/Busy Output	Open-drain status indicator; LOW during program/erase, HIGH when idle - enables polling-free interrupt-driven firmware update handling.
WP#/ACC	Write Protect / Accelerated Program	Input with dual function: LOW enables hardware sector protection; HIGH + elevated voltage enables accelerated programming for production line throughput.

Key Features

Feature	Design Value
Unlock Bypass Programming	Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts firmware update time by ~50% in host-based field upgrades.
Program/Erase Suspend & Resume	Allows reading or programming other sectors mid-operation - enables responsive UI or real-time logging during background flash maintenance.
Secure Silicon Region	Factory-programmed 16-byte serial number in permanently locked 256-byte sector - provides cryptographically verifiable device identity for secure boot chain binding.
Advanced Sector Protection	Combines persistent lock bits and password-protected sectors - prevents unauthorized firmware modification while permitting authorized field updates via authenticated command sequences.
Common Flash Interface (CFI)	JEDEC-standard parameter table accessible via command sequence - enables automatic flash detection and configuration in generic bootloader frameworks (e.g., U-Boot, Coreboot).

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
S29GL064S90FHI040	90 ns access time vs. 70 ns; identical density, package, and feature set.	Lower performance margin for XIP; suitable where timing slack exists in memory bus design.	Select when system clock budget permits longer access latency and cost optimization is prioritized.
MX29GL640EHTI-90G	Macronix part with 90 ns access, no Secure Silicon Region, different CFI implementation, and no password sector protection.	Lacks factory-locked serial number and advanced protection - insufficient for secure boot or anti-counterfeiting use cases.	Choose only for legacy drop-in replacement where security features are unused and JEDEC command compatibility is verified.

Compared with S29GL064S90FHI040 and MX29GL640EHTI-90G, the S29GL064S70FHI040 delivers tighter timing for real-time execution, built-in device identity for secure provisioning, and robust protection mechanisms required in regulated industrial and automotive deployments - making it the only option meeting full functional and security requirements out-of-box.

FAQ

Does S29GL064S70FHI040 support 8-bit data bus operation?

Yes, it supports 8-bit mode via the BYTE# input pin. When BYTE# is driven LOW, the device operates with DQ0–DQ7 as the data bus and treats each access as a byte-wide operation. This mode is fully compatible with the same command set used in 16-bit mode and maintains identical timing specifications except for reduced bandwidth.

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

The WP#/ACC pin serves dual functions: as WP#, it enables hardware-level protection of the first or last sector regardless of software protection settings; as ACC, it accepts elevated voltage (typically 5.5 V) to activate accelerated programming mode - reducing individual word programming time by up to 4× during high-volume manufacturing programming.

How does the Secure Silicon Region differ from standard sector protection?

The Secure Silicon Region is a dedicated 256-byte sector pre-programmed with an 8-word (16-byte) electronic serial number and permanently locked at factory. Unlike standard sector protection, it cannot be unlocked or reprogrammed even with password access - providing immutable device identity for secure boot key derivation and anti-cloning measures.

Is the S29GL064S70FHI040 pinout compatible with earlier S29GL064N devices?

Yes, in the 48-lead TSOP package variant, S29GL064S70FHI040 maintains identical pinout, electrical characteristics, and command set compatibility with S29GL064N devices. However, it adds enhanced features including internal ECC, improved erase suspend behavior, and updated CFI parameter tables - requiring no PCB redesign for migration.
