Product details

Overview

S29GL064S80TFB043 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, 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 supports industrial temperature range (–40°C to +85°C) in 48-ball fine-pitch BGA (VBK048) package. Used for boot code storage in industrial controllers and firmware image retention in network edge devices.

For engineers reviewing the S29GL064S80TFB043 datasheet, S29GL064S80TFB043 pinout, S29GL064S80TFB043 application, or S29GL064S80TFB043 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced I/O (1.65 V to VCC), sector erase suspend/resume capability, and AEC-Q100 Grade 3 qualification for automotive firmware storage.

Technical Context

This device implements a parallel asynchronous interface with separate CE#, OE#, and WE# controls, enabling direct microprocessor bus connection without glue logic. Its MIRRORBIT™ 65-nm process delivers 100,000 erase cycles per sector and 20-year data retention, with automatic hardware ECC applied during read operations.

The architecture supports dual-mode data width: 16-bit only or configurable 8/16-bit via BYTE# input. Sector protection includes persistent lock bits and password-protected regions, while Program/Erase Suspend allows concurrent background operations-critical for real-time firmware updates in embedded systems.

Key Specifications

Use Value: 20-year data retention and 100K-cycle endurance ensure firmware integrity over full equipment lifecycle without replacement.

Use Scenario: Holding boot loader and safety-critical sensor fusion firmware in automotive camera ECU modules certified to AEC-Q100 Grade 3.

IC Role / Device Role / Timing Role: Primary boot memory mapped to ARM Cortex-R5 processor address space; RESET# synchronized to system power-on reset.

Use Value: Hardware sector protection and secure silicon region prevent tampering with ASIL-B compliant boot code during vehicle service.

Network Edge Router Image Storage

Medical Imaging Device Configuration

Use Scenario: Hosting dual firmware images (active + backup) in carrier-grade Ethernet switches requiring zero-downtime upgrades.

IC Role / Device Role / Timing Role: Parallel NOR flash interfaced directly to MIPS-based SoC; Erase Suspend allows background image validation during active traffic.

Use Value: 128-word write buffer and Unlock Bypass reduce 2-MB firmware update time from >3 s to <1.8 s, minimizing service window.

Use Scenario: Storing calibration tables, regulatory compliance metadata, and UI language packs in FDA-cleared ultrasound systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFB043	90 ns access time (vs. 70 ns); otherwise identical architecture, pinout, and command set	Lower performance margin for XIP-critical designs; same endurance, ECC, and security features	Select when 70 ns timing is not required and cost optimization is prioritized
MX29GL640EHTI-90G	Macronix device; 90 ns access, no integrated ECC, different CFI implementation, requires external error handling	Lacks hardware ECC and secure silicon region - unsuitable for safety-critical or secure boot applications	Consider only for cost-sensitive, non-safety applications where software ECC is acceptable

Compared with S29GL064S80TFB043, the 90 ns Infineon variant trades speed for cost while retaining all security and reliability features; the Macronix alternative omits hardware ECC and secure silicon, increasing system-level validation burden for medical or automotive use.

FAQ

Is S29GL064S80TFB043 pin-compatible with earlier S29GL064N or S29GL064P devices?

No. S29GL064S80TFB043 uses the VBK048 48-ball fine-pitch BGA package, while S29GL064N/P variants use 48-pin TSOP or 56-pin TSOP packages. Physical pinout, ball map, and thermal characteristics differ significantly - board redesign is required for migration.

Does this device support 8-bit data bus operation?

Yes. When the BYTE# input is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ8–DQ15 disabled. This maintains compatibility with legacy 8-bit microcontrollers while preserving full 16-bit bandwidth when needed.

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

During normal operation, asserting WP# low permanently protects the first or last sector from program/erase commands - even during accelerated programming. The ACC function activates only when a high voltage (typically 9 V) is applied, enabling faster factory programming.

How is the secure silicon region accessed and locked?

The secure silicon region is accessed via a dedicated command sequence (Enter Secure Silicon Region), then programmed using standard word-program commands. Once the PPB (Persistent Protection Bit) is set, the region becomes permanently read-only - no further writes or erases are possible, even with reset or power cycle.
