Infineon Technologies S29GL064S70TFI060

Overview

S29GL064S70TFI060 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, industrial temperature range (–40°C to +85°C), and TSOP-48 packaging - used in boot code storage for industrial controllers and firmware update modules.

For engineers reviewing the S29GL064S70TFI060 datasheet, S29GL064S70TFI060 pinout, S29GL064S70TFI060 application, or S29GL064S70TFI060 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, secure silicon region with factory-programmed 16-byte serial number, and VIO-controlled I/O voltage scaling (1.65 V to VCC).

Technical Context

The S29GL064S70TFI060 implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, enabling deterministic timing for boot ROM access in microcontroller-based systems. Its MIRRORBIT™ 65-nm process delivers 100,000 erase cycles per sector and 20-year data retention, while internal hardware ECC operates transparently during read operations without host intervention.

It supports dual-mode word/byte configuration via BYTE# input, allowing 16-bit or 8-bit data bus operation. The Secure Silicon Region (128-word / 256-byte) is permanently locked at factory or by customer command, providing tamper-resistant storage for cryptographic keys or calibration data.

FAQ

Is S29GL064S70TFI060 compatible with JEDEC-standard parallel NOR flash interfaces?

Yes. It implements the JEDEC JESD21C standard for single-power-supply flash, including pinout compatibility, command set alignment (e.g., autoselect, chip erase, sector erase), and CFI query structure. Host systems designed for other JEDEC-compliant 16-bit parallel NOR devices can integrate it with minimal firmware changes.

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

In normal operation, asserting WP# low protects the first or last 64-KB sector from accidental erase or program. During accelerated programming, applying 5.5 V to ACC (via WP#/ACC pin) reduces program time by ~30%. The pin is multiplexed: logic-level control for protection, high-voltage for speed optimization.

Does the Secure Silicon Region support customer programming after shipment?

Yes - the 128-word Secure Silicon Region can be programmed and permanently locked either at the factory or by the customer using the Enter Secure Silicon Region command sequence. Once locked via PPB (Persistent Protection Bit), no further writes or erases are possible, even with reset or power cycle.

How does hardware ECC operate without host software involvement?

Internal ECC logic automatically calculates and checks Hamming codes on every read access. If a single-bit error is detected, it is corrected in real time before data reaches DQ pins; the status register (bit 15) flags correction occurrence. No host driver, interrupt, or register polling is required - correction is fully transparent.
