Infineon Technologies S29GL064S80BHV030

Overview

S29GL064S80BHV030 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC 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 operates across –40°C to +105°C (Industrial Plus grade). Used in boot code storage for industrial controllers.

For engineers reviewing the S29GL064S80BHV030 datasheet, S29GL064S80BHV030 pinout, S29GL064S80BHV030 application, or S29GL064S80BHV030 equivalent, key selection criteria include parallel 16-bit bus interface, sector-level erase flexibility, JEDEC CFI compliance, hardware reset (RESET#), and WP#/ACC-enabled accelerated programming support.

Technical Context

This device implements a command-set–compatible JEDEC single-power-supply flash architecture with dedicated CE#, WE#, and OE# controls. Its MIRRORBIT™ 65-nm process enables hot-hole assisted sector erase and hot-electron injection programming, supporting both uniform and boot-sector configurations.

Hardware features include Erase/Program Suspend & Resume, Ready/Busy# status signaling, automatic low-VCC write inhibition, and persistent/password-based sector protection. The Secure Silicon Region is a dedicated 256-byte area permanently locked after factory or customer programming.

FAQ

What is the function of the WP#/ACC pin on S29GL064S80BHV030?

The WP#/ACC pin serves dual roles: when pulled low, it protects the first or last sector from accidental program/erase; when driven to elevated voltage (typically 9–12 V), it enables accelerated programming mode for faster production-line flashing. This pin operates independently of software protection settings and remains active during all device states.

Does S29GL064S80BHV030 support byte-wide data access?

Yes, it supports 8-bit data access via the BYTE# input. When BYTE# is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0 functioning as the least-significant address bit. This allows compatibility with 8-bit microcontrollers without external data bus multiplexing.

How is the Secure Silicon Region programmed and locked?

The Secure Silicon Region is programmed using the Enter/Exit Secure Silicon Region command sequence and locked permanently via the PPB lock bit. Once locked, no further writes or erases are possible-even with elevated ACC voltage or unlock commands. Factory programming includes a unique 16-byte electronic serial number written before shipment.

Can S29GL064S80BHV030 be used in place of older S29GL064N devices?

No-it is not a drop-in replacement. While both are 64 Mb parallel NOR flash, the S29GL064S uses MIRRORBIT™ 65-nm technology with different command timing, ECC behavior, and Secure Silicon Region implementation. Migration requires validation of command sequences, timing margins, and status bit interpretation per the Rev. *K datasheet.
