Product details

Overview

S29GL064S80DHV040 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 serves as boot code storage in industrial microcontroller systems requiring AEC-Q100 Grade 2 compliance (–40°C to +105°C).

For engineers reviewing the S29GL064S80DHV040 datasheet, S29GL064S80DHV040 pinout, S29GL064S80DHV040 application, or S29GL064S80DHV040 equivalent, key selection criteria include uniform 64-KB sector architecture, VIO-referenced I/O (1.65 V to VCC), JEDEC-compliant command set, and hardware reset (RESET#) with RY/BY# status signaling.

Technical Context

This device implements MIRRORBIT™ flash technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming across uniform 64-KB sectors. Its logical organization is 4,194,304 × 16-bit words, supporting byte-mode operation via BYTE# input when configured for 8-bit data bus use.

The architecture integrates dedicated hardware features including automatic ECC, Erase/Program Suspend & Resume, persistent and password-based sector protection, and a secure silicon region accessible only through defined command sequences - all operating under single 3.0 V supply without auxiliary voltages.

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 - enables direct execution (XIP) from flash in real-time MCU boot paths
Write Buffer Size	128-word (256-byte) - 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 safety-critical firmware storage
VIO Range	1.65 V to VCC - allows flexible I/O voltage scaling independent of core VCC for mixed-voltage system interfacing
Endurance	100,000 erase cycles per sector - supports field firmware updates over 10+ year product lifecycle
Data Retention	20 years typical - ensures boot image integrity across automotive and industrial temperature ranges

Pinout & Package

Package: 48-ball fine-pitch BGA (VBK048, 8.15 mm × 6.15 mm × 1.0 mm), industrial-plus temperature grade (–40°C to +105°C), lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address Inputs	23-bit address bus supporting full 64-Mb addressing; A0 selects LSB in word mode or byte in byte mode
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; operates as 8-bit when BYTE# = low
CE#	Chip Enable	Active-low chip select; device enters standby when CE# high and RESET# high
OE#	Output Enable	Controls output drivers during read; does not affect internal operations
WE#	Write Enable	Initiates command latching or data loading; required for all program/erase sequences
RESET#	Hardware Reset	Aborts ongoing operation and returns device to reading state; tied to system reset for boot recovery
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active program/erase; used for polling-free timing control
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high voltage = enables accelerated programming during production
BYTE#	Bus Width Select	Low = 8-bit data mode (DQ0–DQ7 active); high = 16-bit word mode
VIO	I/O Voltage Reference	Sets input threshold and output drive level; decouples I/O voltage from VCC for mixed-signal interfacing

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-locked area with electronic serial number - provides immutable device identity for secure boot and anti-cloning
Program/Erase Suspend	Allows host to interrupt ongoing program/erase to service higher-priority reads - essential for real-time OS firmware updates
Unlock Bypass Mode	Reduces multi-word programming to two write cycles instead of four - cuts firmware patch time by ~50% in host-controlled updates
JEDEC CFI Compliance	Enables automatic detection and configuration by bootloader - eliminates hard-coded flash parameters in embedded startup code
Persistent Sector Protection	Non-volatile lock bits prevent accidental erase/write even after power cycle - replaces legacy 12 V protection schemes

FAQ

Does S29GL064S80DHV040 support byte-wide data access?

Yes. When BYTE# is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, while A0 functions as the least-significant address bit. This enables compatibility with 8-bit microcontrollers and reduces PCB routing complexity without requiring external data bus multiplexing.

What is the function of the WP#/ACC pin in normal operation?

In normal operation, WP#/ACC acts as a write-protect input: when pulled low, it permanently locks the first or last 64-KB sector against program and erase commands, regardless of software protection settings. This hardware-level lock remains active even during accelerated programming cycles.

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 customer command. Once locked, no further writes or erases are possible - unlike standard sectors, it cannot be unlocked or reconfigured, providing immutable storage for serial numbers or cryptographic keys.

Is the 70 ns access time guaranteed across the full industrial-plus temperature range?

Yes. The 70 ns access time is specified and tested over the full –40°C to +105°C range at VCC = 2.7–3.6 V and VIO = 1.65–VCC. This guarantee is documented in the "DC and AC Characteristics" table (page 68) of the official Infineon datasheet 001-98286 Rev. *K.
