Product details

Overview

S29GL064S90FHVV20 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 - used in automotive boot code storage and industrial firmware retention.

For engineers reviewing the S29GL064S90FHVV20 datasheet, S29GL064S90FHVV20 pinout, S29GL064S90FHVV20 application, or S29GL064S90FHVV20 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, unlock bypass programming, and AEC-Q100 Grade 2 qualification for automotive embedded systems.

Technical Context

The S29GL064S90FHVV20 implements a uniform sector architecture with 128 × 32-Kword (64-KB) sectors and supports both 16-bit and byte-wide (8-bit) data bus operation via BYTE# control. It uses hot-electron injection for programming and hot-hole assisted erase at the sector level.

Its internal ECC engine operates transparently during read cycles to correct single-bit errors, while the secure silicon region provides permanent 256-byte storage accessible only through dedicated command sequences - not mapped into main array address space.

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 microcontroller 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
Endurance	100,000 erase/program cycles per sector - supports field firmware updates over 10+ years of operation
Data Retention	20 years typical at 85°C - validated for automotive ECU long-term code storage without refresh
Supply Voltage	VCC = 2.7–3.6 V; VIO = 1.65–VCC - decouples I/O voltage from core, enabling mixed-voltage system interfacing

Pinout & Package

Package: 48-ball fine-pitch BGA (VBK048, 8.15 mm × 6.15 mm × 1.0 mm), industrial-plus temperature range (–40°C to +105°C), 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 16-bit mode
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; functions as DQ0–DQ7 in byte mode when BYTE# = LOW
CE#	Chip Enable	Active-low enable controlling device selection; must be asserted for all read/write/erase operations
OE#	Output Enable	Active-low control for output buffer; allows data read without toggling CE# or WE#
WE#	Write Enable	Active-low signal latching address/data during command sequences and programming cycles
RESET#	Hardware Reset	Asynchronous active-low reset that terminates ongoing operations and returns device to read mode
RY/BY#	Ready/Busy Output	Open-drain status indicator - LOW during program/erase, HIGH when operation complete or in read mode
WP#/ACC	Write Protect / Accelerated Program	Logic LOW protects first/last sector; high-voltage on this pin enables accelerated programming in production
BYTE#	Bus Width Select	LOW configures 8-bit data bus (DQ0–DQ7); HIGH enables full 16-bit operation

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-locked area with electronic serial number - prevents cloning and enables secure boot key storage
Erase Suspend/Resume	Pause background sector erase to read/program other sectors - maintains real-time responsiveness in multitasked firmware environments
Unlock Bypass Programming	Two-cycle command sequence instead of four - cuts multi-word programming latency by 50% in host-controlled updates
Persistent Sector Protection	Non-volatile lock bits disable program/erase permanently until reset via dedicated command - replaces legacy 12-V protection schemes
CFI Compliance	JEDEC-standard Common Flash Interface - enables automatic detection and configuration by bootloader without hard-coded timing tables

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
S29GL064S90TFIV20	Same die, 56-pin TSOP package, industrial temp (–40°C to +85°C)	Lacks AEC-Q100 qualification; no 105°C rating	Select for cost-sensitive industrial designs where BGA assembly is unavailable
MX29GL640EHT2I-90G	64 Mb parallel NOR, 90 ns access, no integrated ECC, different command set	Requires external error handling; not CFI-compliant	Choose only if legacy system compatibility mandates Macronix command mapping

Compared with S29GL064S90FHVV20, the TSOP variant trades thermal robustness for assembly simplicity, while the Macronix part sacrifices ECC and CFI support for marginally lower unit cost - neither matches the combined AEC-Q100 Grade 2, hardware ECC, and secure silicon capabilities of the VBK048 BGA version.

FAQ

What is the function of the WP#/ACC pin on S29GL064S90FHVV20?

The WP#/ACC pin serves dual roles: when held LOW, it hardware-protects the first or last memory sector against accidental erase or program; when driven to 5.5 V during manufacturing, it enables accelerated programming mode for faster production-line flashing. This pin remains functional even when persistent sector protection is enabled.

Does S29GL064S90FHVV20 support byte-wide data access?

Yes - asserting BYTE# = LOW configures the device for 8-bit data bus operation using DQ0–DQ7, while maintaining full 16-bit addressing. This mode is fully supported in all command sequences including program, erase, and autoselect, and preserves sector protection and ECC functionality.

How is the Secure Silicon Region accessed and protected?

The Secure Silicon Region is accessed only via dedicated Enter/Exit Secure Silicon Region command sequences (not standard read/write commands). Once locked using the PPB lock bit, it becomes permanently read-only - no further writes or erases are possible, even with RESET# assertion or power cycling.

What temperature grades are supported by the VBK048 package variant?

The S29GL064S90FHVV20 in 48-ball VBK048 package is qualified for Industrial Plus (–40°C to +105°C) and Automotive AEC-Q100 Grade 2 (–40°C to +105°C) operation. Its thermal performance is validated per JESD22-A108 and JESD22-A104 standards with full electrical specification compliance across the range.
