Infineon Technologies S29GL064S80DHIV10

Overview

S29GL064S80DHIV10 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, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, industrial temperature range (–40°C to +85°C), and 48-lead TSOP package - used in boot code storage for industrial control systems requiring deterministic read latency and sector-level erase flexibility.

For engineers reviewing the S29GL064S80DHIV10 datasheet, S29GL064S80DHIV10 pinout, S29GL064S80DHIV10 application, or S29GL064S80DHIV10 equivalent, this device supports JEDEC-compliant command sets, byte/word configuration via BYTE# input, secure silicon region programming, and Erase/Program Suspend for real-time firmware updates in resource-constrained embedded hosts.

Technical Context

The S29GL064S80DHIV10 implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, supporting both 16-bit-only and configurable 8/16-bit data bus modes. Its MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming with 100,000 erase cycles per sector and 20-year data retention.

Hardware protection includes VCC brown-out detection, WP#/ACC-driven first/last sector lock, RESET#-initiated operation abort, and RY/BY# status signaling. The Secure Silicon Region provides 256-byte factory- or customer-programmable locked storage accessible only via dedicated command sequence.

FAQ

Does S29GL064S80DHIV10 support byte-wide data access?

Yes, it supports configurable 8-bit or 16-bit data bus operation using the BYTE# input. When BYTE# is asserted low, only DQ0–DQ7 are active for byte transfers; when high, all 16 data lines operate in word mode. This enables compatibility with both 8-bit and 16-bit microcontroller buses without external glue logic.

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

The WP#/ACC pin serves dual roles: as WP# (Write Protect), it locks the first or last sector when driven low; as ACC (Accelerated Program), it enables faster programming when driven high with elevated voltage (typically 5.5 V). This dual functionality supports both field-level security and high-throughput manufacturing programming.

How does the Secure Silicon Region differ from standard sectors?

The Secure Silicon Region is a dedicated 256-byte area (128 words) that can be permanently locked at factory or by the user via command sequence. Once locked, no further writes or erases are possible - unlike standard sectors, which remain reprogrammable. It contains a unique 16-byte electronic serial number and is accessed only through explicit Enter/Exit commands.

Is hardware reset (RESET#) required for reliable boot operation?

Yes. The RESET# pin provides asynchronous termination of any ongoing erase or program operation and forces the device into read mode. In boot-critical systems, tying RESET# to the system reset circuit ensures the flash always starts in a known state - preventing corrupted reads during power-up sequencing or brown-out recovery.
