Product details

Overview

S29GL064S80TFB040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC using 65-nm MIRRORBIT™ technology, operating from a single 3.0 V supply with 70 ns access time and integrated hardware ECC for single-bit error correction. It features 128 uniform 64-KB sectors, 100,000 erase cycles per sector, and 20-year data retention, deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL064S80TFB040 datasheet, S29GL064S80TFB040 pinout, S29GL064S80TFB040 application, or S29GL064S80TFB040 equivalent, key selection criteria include JEDEC-compliant command set, VIO-controlled I/O (1.65–VCC), Secure Silicon Region (256-byte factory-lockable area), and support for Program/Erase Suspend/Resume in real-time firmware update scenarios.

Technical Context

This device implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, supporting both 16-bit word and (via BYTE# input) 8-bit byte configuration. Its architecture includes a 128-word write buffer and 8-word read buffer to accelerate multi-word programming and page reads.

The internal ECC engine operates transparently during read cycles, correcting single-bit errors without host intervention. Sector protection combines persistent lock bits and password-protected regions, while hardware RESET# and WP#/ACC inputs enable system-level production programming and first/last sector write protection independent of software settings.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (8 MB), organized as 4,194,304 × 16-bit words
Access Time	70 ns - defines maximum read latency under specified VCC and load conditions
Erase Endurance	100,000 cycles per sector - supports frequent field firmware updates in industrial controllers
Data Retention	20 years typical - ensures long-term reliability in unpowered storage applications
Supply Voltage	VCC = 2.7–3.6 V; VIO = 1.65–VCC - enables flexible I/O voltage scaling with host logic
Operating Temp	–40°C to +105°C (Industrial Plus grade) - qualified for extended-temperature embedded deployments
ECC Capability	Internal hardware single-bit error correction - eliminates need for external error-handling logic

Pinout & Package

Package: 48-ball fine-pitch BGA (VBK048, 8.15 mm × 6.15 mm × 1.0 mm), RoHS-compliant, lead-free.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing space
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# selects 8-bit mode
CE#	Chip Enable	Active-low chip select; disables device when high to reduce standby current
OE#	Output Enable	Active-low control for output drivers; enables read data only when asserted
WE#	Write Enable	Active-low control for write/program/erase command latching
RESET#	Hardware Reset	Active-low asynchronous reset that terminates ongoing operations and restores ready state
RY/BY#	Ready/Busy Output	Open-drain status indicator: low = operation in progress, high = ready
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high-voltage pulse enables accelerated programming
VIO	I/O Supply Input	Sets logic threshold for all address, control, and data pins (1.65–VCC)

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-programmable and permanently lockable area for serial numbers or security keys
Program/Erase Suspend	Allows host to interrupt active program/erase to read/write other sectors - essential for real-time multitasking firmware
Unlock Bypass Mode	Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts total update time by ~50%
Common Flash Interface (CFI)	Enables automatic device identification and parameter retrieval at boot - simplifies host driver development
Hardware VCC Monitor	Internally inhibits writes during power ramp-up/down - prevents corruption during brown-out or cold-start

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
S29GL064S90TFB040	90 ns access time vs. 70 ns; otherwise identical architecture, package, and feature set	Lower performance margin acceptable in non-real-time boot paths or cost-sensitive designs	Select when 70 ns timing is not required and unit cost is prioritized
S29GL064S80TFI040	Same 70 ns speed but in 48-lead TSOP package (vs. VBK048 BGA); identical electrical specs	Preferred for legacy PCB layouts or prototyping where BGA rework is impractical	Select when board assembly constraints favor through-hole or gull-wing packaging

Compared with S29GL064S90TFB040 and S29GL064S80TFI040, the S29GL064S80TFB040 uniquely balances highest-speed BGA packaging with industrial-plus temperature range and Secure Silicon Region - making it optimal for space-constrained, high-reliability embedded boot applications demanding both performance and physical security.

FAQ

What is the function of the VIO pin on the S29GL064S80TFB040?

The VIO pin sets the input voltage threshold and output drive level for all address, control, and data signals. It must be supplied within 1.65 V to VCC (2.7–3.6 V) to ensure correct logic interpretation and signal integrity with host processors operating at different I/O voltages - enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic families without level shifters.

Does the S29GL064S80TFB040 support byte-wide data access?

Yes, the device supports 8-bit data access when the BYTE# input is asserted low. In this mode, DQ0–DQ7 operate as the data bus while DQ8–DQ15 are disabled. This configuration is commonly used in microcontrollers with 8-bit external memory buses and reduces PCB routing complexity compared to full 16-bit interfaces.

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 at factory or by the customer using a command sequence. Once locked, no further programming or erasure is possible - unlike standard sectors protected by software locks or passwords, which remain modifiable if credentials are known or bypassed.

Can the S29GL064S80TFB040 be used in automotive applications?

Yes, the S29GL064S80TFB040 is qualified to AEC-Q100 Grade 2 (–40°C to +105°C) and supports automotive instrument clusters, ADAS control modules, and infotainment boot memory. Its hardware RESET# pin, WP#/ACC protection, and 20-year data retention meet functional safety requirements for ASIL-B–capable systems when integrated with appropriate host-level error handling.
