Infineon Technologies S29GL064S70DHI010

Overview

S29GL064S70DHI010 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, and 65-nm MIRRORBIT™ process technology. It features uniform 64-KB sectors, internal hardware ECC for single-bit error correction, and secure silicon region with factory-programmed 16-byte electronic serial number. Used in industrial embedded boot code storage where deterministic timing and data integrity are critical.

For engineers reviewing the S29GL064S70DHI010 datasheet, S29GL064S70DHI010 pinout, S29GL064S70DHI010 application, or S29GL064S70DHI010 equivalent, this device supports JEDEC-compliant command sets, byte/word configuration via BYTE# input, and hardware reset (RESET#) for reliable boot initialization in safety-critical systems.

Technical Context

The S29GL064S70DHI010 implements a parallel interface with 16-bit data bus (8-bit mode enabled by BYTE#), separate CE#, WE#, and OE# controls, and VIO-referenced I/O (1.65 V to VCC). Its architecture includes 128 uniform 64-KB sectors and supports autoselect, CFI, and unlock bypass programming.

It integrates hardware-based data protection: low-VCC write inhibit, WP#/ACC-driven sector lock, and RESET#-initiated operation termination. Erase suspend/resume and program suspend/resume enable concurrent read/program operations across non-target sectors during background erase or program cycles.

FAQ

What is the function of the BYTE# pin on S29GL064S70DHI010?

The BYTE# pin configures the data bus width: when pulled LOW, it enables 8-bit mode using only DQ0–DQ7; when HIGH, it enables full 16-bit mode using DQ0–DQ15. This allows flexible integration with 8-bit or 16-bit microcontrollers without external bus multiplexing logic. The pin must be stable before any command sequence begins and remains static during active operations.

Does S29GL064S70DHI010 support execute-in-place (XIP) operation?

Yes - its parallel interface and 70 ns access time enable direct instruction fetch from flash without copying to RAM. XIP is supported in both 8-bit and 16-bit configurations, provided the host processor's external bus interface meets timing requirements for CE#, OE#, and address setup/hold. No additional configuration registers or enable bits are required.

How is the Secure Silicon Region protected after factory programming?

The 128-word Secure Silicon Region is permanently locked via fuse-based hardware protection. Once programmed and locked, no further writes or erases are possible-even with valid unlock sequences or high-voltage ACC signals. The lock is irreversible and survives power cycles, resets, and reprogramming attempts. Access requires explicit command entry (Enter Secure Silicon Region), but modification is physically disabled.

Can S29GL064S70DHI010 operate with VIO = 1.8 V while VCC = 3.0 V?

Yes - VIO is independent of VCC and may be set between 1.65 V and VCC. At VIO = 1.8 V, all input thresholds (address, control, data) and output drive levels conform to 1.8 V logic standards, enabling direct interfacing with 1.8 V FPGAs or ASICs while maintaining 3.0 V core operation for optimal endurance and retention. This dual-voltage capability is verified per datasheet Table 6-1.
