Infineon Technologies S29GL064S70TFA030

Overview

S29GL064S70TFA030 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 correction, and secure silicon region with factory-programmed 8-word electronic serial number. It serves as boot code storage in industrial microcontroller systems requiring high reliability and AEC-Q100 Grade 2 compliance.

For engineers reviewing the S29GL064S70TFA030 datasheet, S29GL064S70TFA030 pinout, S29GL064S70TFA030 application, or S29GL064S70TFA030 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, unlock bypass programming, and flexible VIO-controlled I/O voltage (1.65 V to VCC) for mixed-voltage host interfacing.

Technical Context

This device implements a uniform-sector architecture with 128 × 32-Kword (64-KB) sectors and uses 65-nm MIRRORBIT™ floating-gate technology for hot-electron programming and hot-hole assisted erase. It integrates dedicated hardware logic for automatic ECC correction, status monitoring via DQ6/DQ7 polling and RY/BY# output, and persistent sector protection independent of VCC transitions.

The command interface supports full CFI compliance, autoselect mode for system identification, and advanced features including Program Suspend/Resume and Erase Suspend/Resume - enabling concurrent read operations during active program/erase cycles in other sectors without interrupting execution flow.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70TFA030?

The WP#/ACC pin serves dual functions: when held low, it permanently protects the first or last sector from program/erase operations regardless of software protection settings; when driven high with elevated voltage (typically 5.5 V), it enables accelerated programming mode to reduce write times during manufacturing. This pin operates independently of VCC and remains active during power transitions.

Does S29GL064S70TFA030 support byte-wide data access?

Yes, the device supports both 16-bit and 8-bit data bus configurations via the BYTE# input. When BYTE# is low, only DQ0–DQ7 are active for 8-bit transfers; when high, all 16 data lines operate in word mode. Address lines remain fully functional in either mode, and command sequences are identical - no software changes are needed to switch bus widths.

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 using a command sequence. Once locked, no further writes or erases are possible - even with elevated voltage or reset. It contains an 8-word electronic serial number and is used for immutable device identity, cryptographic key storage, or calibration data that must survive all future firmware updates.

Can S29GL064S70TFA030 be used in systems with 1.8 V I/O interfaces?

Yes, the device supports 1.8 V I/O through its VIO pin, which accepts 1.65 V to VCC (3.0 V). When VIO = 1.8 V, all input thresholds and output drive levels conform to 1.8 V logic standards while the core remains powered at 3.0 V. This eliminates level-shifting components in mixed-voltage SoC designs and maintains full JEDEC command compatibility without timing derating.
