Product details

Overview

S29GL064S80BHV040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC 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 industrial temperature range (–40°C to +85°C) in 48-ball fine-pitch BGA (VBK048) package.

For engineers reviewing the S29GL064S80BHV040 datasheet, S29GL064S80BHV040 pinout, S29GL064S80BHV040 application, or S29GL064S80BHV040 equivalent, this device serves as boot code storage in automotive ECUs, firmware storage in industrial HMIs, and configuration memory in telecom baseband processors where deterministic read latency and sector-level erase control are required.

Technical Context

This device implements a parallel asynchronous interface with separate CE#, OE#, and WE# controls, supporting both 16-bit word and 8-bit byte configurations via BYTE# input. Its MIRRORBIT™ 65-nm process enables hot-hole assisted sector erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention.

Hardware features include RESET#-driven hard reset, RY/BY# status output, WP#/ACC-enabled accelerated programming and first/last sector write protection, and low-VCC detection that inhibits writes during power transitions. The Secure Silicon Region is 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 bits), organized as 128 uniform 64-KB sectors
Access Time	70 ns typical - ensures deterministic boot code fetch timing in real-time embedded systems
Write Buffer Size	128-word (256-byte) - reduces multi-word programming overhead by batching writes
ECC Capability	Internal hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage
Endurance	100,000 erase cycles per sector - supports field firmware updates over full product lifecycle
Data Retention	20 years typical at 85°C - validated for automotive and industrial deployments without refresh
Operating Voltage	VCC = 2.7–3.6 V; VIO = 1.65–VCC - decouples I/O voltage from core supply for mixed-voltage system interfacing

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–A22	Address Inputs	23-bit address bus supporting full 4-Mword addressing space; A0 selects LSB in word mode or bit 0 in byte mode
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; functions as 8-bit when BYTE# = LOW, enabling flexible host interface design
CE#	Chip Enable	Active-low chip select; device enters standby when CE# HIGH, enabling multi-device memory mapping
OE#	Output Enable	Active-low output control; allows shared data bus operation without tristate conflicts
WE#	Write Enable	Active-low write strobe; latches command sequences and data during programming/erase operations
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing operations and restores device to known state for boot recovery
RY/BY#	Ready/Busy Output	Open-drain status indicator; LOW during active program/erase, enabling polling-free interrupt-driven firmware flow
WP#/ACC	Write Protect / Accelerated Program	Multi-function pin: LOW enables sector write protection; high-voltage pulse enables accelerated programming for production line throughput
BYTE#	Bus Width Select	Configures DQ bus as 16-bit (HIGH) or 8-bit (LOW); critical for legacy microcontroller compatibility
VCC	Core Supply	3.0 V ±10% supply powering core logic and memory array; supports single-rail system design
VIO	I/O Supply	1.65–3.6 V programmable I/O voltage - matches host processor I/O levels without level shifters
VSS	Ground	Dedicated ground pins for core and I/O domains - minimizes noise coupling between logic and data paths

Key Features

Feature	Design Value
Secure Silicon Region	256-byte factory- or customer-lockable area with permanent protection - stores cryptographic keys or calibration data immune to field reprogramming
Program/Erase Suspend	Allows read access to unprotected sectors during active program/erase - enables concurrent firmware update and runtime execution
Unlock Bypass Mode	Reduces multi-word programming from 4 to 2 write cycles - cuts flash update time by ~50% in bootloader implementations
Advanced Sector Protection	Persistent and password-based sector locking - prevents unauthorized firmware modification in certified automotive and industrial systems
CFI Compliance	JEDEC-standard Common Flash Interface - enables automatic device identification and parameter retrieval in generic flash drivers

Applications

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
S29GL064S90BHV040	90 ns access time vs. 70 ns; identical density, package, and feature set	Lower performance grade suitable for cost-sensitive non-real-time firmware storage	Select when boot timing margin exceeds 90 ns and BOM cost optimization is prioritized
MX29GL640EHTI-90G	Macronix part with 90 ns access, no Secure Silicon Region, different CFI implementation	Lacks factory-programmed serial number and persistent password protection	Choose only if security features are not required and cross-vendor qualification is complete

Compared with S29GL064S80BHV040, the 90 ns variant trades deterministic boot latency for lower unit cost, while the Macronix alternative omits secure silicon and requires CFI driver adaptation - making the Infineon part optimal for safety- and security-critical designs requiring guaranteed timing and tamper-proof identity.

FAQ

What is the function of the WP#/ACC pin on S29GL064S80BHV040?

The WP#/ACC pin serves dual roles: when held LOW, it protects the first or last sector from accidental programming or erasure; when driven to 5.5 V (±0.3 V), it enables accelerated programming mode for faster production-line firmware loading. This dual functionality eliminates need for separate hardware protection and programming enable signals.

Does S29GL064S80BHV040 support byte-wide data access?

Yes - when the BYTE# pin is driven LOW, the device configures DQ0–DQ7 as an 8-bit data bus while DQ8–DQ15 are disabled. This mode maintains full addressability and command compatibility, enabling direct connection to 8-bit microcontrollers without external data bus multiplexing.

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. Once locked, no further writes or erases are possible - even with elevated voltage or unlock bypass commands - making it suitable for storing immutable cryptographic keys or calibration constants.

Can S29GL064S80BHV040 operate with VIO = 1.8 V while VCC = 3.0 V?

Yes - VIO is independently configurable from 1.65 V to 3.6 V, allowing the device to interface with 1.8 V host processors while maintaining 3.0 V core operation. All input thresholds and output drive strengths scale with VIO, ensuring signal integrity without external level shifters.
