Infineon Technologies S29GL064S80FHV040

Overview

S29GL064S80FHV040 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. It features 70 ns access time, internal hardware ECC for single-bit error correction, 128-word write buffer, and supports both uniform and boot-sector architectures with 100,000 erase cycles per sector - deployed in automotive instrument clusters for firmware storage and boot code execution.

For engineers reviewing the S29GL064S80FHV040 datasheet, S29GL064S80FHV040 pinout, S29GL064S80FHV040 application, or S29GL064S80FHV040 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced I/O (1.65–VCC), hardware reset (RESET#), Ready/Busy# status signaling, and Secure Silicon Region for factory-locked 256-byte identity storage.

Technical Context

This device implements a parallel interface with 16-bit data bus (BYTE# configurable for 8-bit mode), separate CE#, WE#, and OE# controls, and supports both chip- and sector-erase operations. Its architecture enables Program Suspend/Resume and Erase Suspend/Resume - allowing concurrent read access to unprotected sectors during active programming or erasure.

Internal hardware ECC operates transparently during read cycles, correcting single-bit errors without host intervention. The Secure Silicon Region is a dedicated 128-word (256-byte) sector with permanent lock capability, accessible only via defined command sequences and programmable at factory or by customer for electronic serial number storage.

FAQ

What is the function of the VIO pin on the S29GL064S80FHV040?

The VIO pin sets the voltage reference for all input and output logic thresholds, enabling operation across 1.65 V to VCC. This decouples I/O signaling from core VCC, allowing interoperability with mixed-voltage host systems - for example, interfacing with a 1.8 V FPGA while maintaining 3.0 V core operation. It does not power internal circuitry.

Does the S29GL064S80FHV040 support byte-wide data access?

Yes, the device supports 8-bit data access via the BYTE# input pin. When BYTE# is asserted low, DQ0–DQ7 operate as an 8-bit data bus while DQ8–DQ15 are disabled. This mode is fully compatible with JEDEC-standard command sequences and preserves all sector protection and ECC functionality.

How is the Secure Silicon Region programmed and locked?

The Secure Silicon Region is accessed via a specific command sequence (Enter Secure Silicon Region), then programmed using standard Word Program commands. Locking is performed with the Persistent Protection Bit (PPB) lock command - once locked, no further writes or erases are possible, even with RESET# assertion or power cycling. Factory programming is also supported.

Can the S29GL064S80FHV040 be used in place of older S29GL064N devices?

No - the S29GL064S uses a different command set, lacks the 12 V VPP pin, and introduces new features like VIO-referenced I/O and enhanced sector protection. While pin-compatible in some packages, software drivers must be updated to support CFI queries, Unlock Bypass, and Secure Silicon Region commands.
