Infineon Technologies S29GL064S80BHB040

Overview

S29GL064S80BHB040 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 error correction, and secure silicon region with factory-programmed 128-word electronic serial number - used for boot code storage in industrial control systems.

For engineers reviewing the S29GL064S80BHB040 datasheet, S29GL064S80BHB040 pinout, S29GL064S80BHB040 application, or S29GL064S80BHB040 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, unlock bypass programming, and flexible 16-bit/8-bit data bus configuration via BYTE# input.

Technical Context

This device implements MIRRORBIT™ floating-gate technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron program operations across uniform 64-KB sectors. It integrates dedicated status monitoring via DQ6/DQ7 polling and RY/BY# output, with automatic ECC correction applied during read cycles.

The architecture supports dual-mode data bus operation (16-bit default, 8-bit with BYTE# asserted), independent CE#/OE#/WE# controls, and hardware reset (RESET#) that terminates active operations and restores device readiness - critical for reliable boot firmware recovery in embedded systems.

FAQ

Does S29GL064S80BHB040 support 8-bit data bus operation?

Yes. When the BYTE# pin is driven low, the device operates in 8-bit mode using DQ0–DQ7 only, while DQ8–DQ15 are tri-stated. This mode is fully supported in all command sequences including program, erase, and read operations, and maintains full sector protection and ECC functionality.

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

In normal operation, WP#/ACC acts as a write-protect input: asserting it low disables programming and erasure of the first or last sector, regardless of software protection settings. During accelerated programming, applying VHH (~11.5 V) to this pin enables faster program times without altering sector protection states.

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 at factory or by customer command. Once locked, no further writes or erases are possible - even with unlock commands - preserving serial numbers, keys, or calibration data across the device's lifetime.

Is automatic ECC applied during every read operation?

Yes. Internal hardware ECC is enabled by default and operates transparently on every read access. It detects and corrects single-bit errors within each 512-byte block without CPU intervention or additional latency, and reports uncorrectable multi-bit errors via status register bit SR7.
