Infineon Technologies S29GL064S90FHI013

Overview

S29GL064S90FHI013 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 controllers requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).

For engineers reviewing the S29GL064S90FHI013 datasheet, S29GL064S90FHI013 pinout, S29GL064S90FHI013 application, or S29GL064S90FHI013 equivalent, key selection criteria include JEDEC-compliant command set, uniform 64-KB sector architecture, VIO-referenced I/O (1.65 V to VCC), hardware RESET# and RY/BY# status signaling, and boot-sector model support with eight 8-KB sectors.

Technical Context

This device implements a parallel interface with 16-bit data bus (BYTE# configurable for 8-bit mode), uses hot-electron injection for programming and hot-hole assisted erase per sector, and integrates on-die ECC logic that automatically corrects single-bit errors during read operations without host intervention.

Its architectural protection includes persistent sector lock bits, password-protected sectors requiring 16-byte authentication, and a dedicated 256-byte Secure Silicon Region permanently locked after factory or customer programming - all managed via standard CFI-compliant command sequences.

FAQ

What is the function of the WP#/ACC pin on S29GL064S90FHI013?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector regardless of software protection settings; when pulsed to high voltage (VHH), it enables accelerated programming for faster production-line firmware loading. This pin operates independently of VCC and remains functional during accelerated program mode.

Does S29GL064S90FHI013 support byte-wide data access?

Yes, S29GL064S90FHI013 supports 8-bit data access using the BYTE# input pin. When BYTE# is asserted low, the device operates in 8-bit mode with DQ0–DQ7 active as the data bus while DQ8–DQ15 are disabled. This mode maintains full command compatibility and sector addressing integrity.

How is the Secure Silicon Region programmed and locked?

The Secure Silicon Region (128 words / 256 bytes) is programmed via standard CFI command sequences and permanently locked either at the factory or by the customer using the Persistent Protection Bit (PPB). Once locked, no further writes or erases are possible - even with power cycling or hardware reset - ensuring immutable device identity and secure key storage.

Can S29GL064S90FHI013 be used in systems requiring XIP (eXecute-In-Place) operation?

Yes, S29GL064S90FHI013 supports XIP operation due to its 70 ns access time, deterministic parallel interface timing, and ability to sustain continuous read bursts. Its uniform sector architecture and CFI compliance allow boot ROM initialization and direct instruction fetch without intermediate RAM copying in microcontroller-based systems.
