Infineon Technologies S29GL064S90TFI013

Overview

S29GL064S90TFI013 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, secure silicon region with factory-programmed 16-byte serial number, and operates across –40°C to +85°C industrial temperature range.

For engineers reviewing the S29GL064S90TFI013 datasheet, S29GL064S90TFI013 pinout, S29GL064S90TFI013 application, or S29GL064S90TFI013 equivalent, this device supports boot code storage, firmware update in embedded controllers, and secure configuration data retention in automotive ECUs and industrial HMIs requiring JEDEC-compliant parallel flash with persistent sector protection.

Technical Context

The S29GL064S90TFI013 implements MIRRORBIT™ charge-trapping flash technology on a 65-nm process, enabling hot-hole assisted erase and hot-electron injection programming. It supports both 16-bit and byte-wide (8-bit) data bus operation via BYTE# control, with all I/O levels referenced to VIO (1.65 V to VCC).

Its command-set architecture is fully JEDEC JESD21-C compliant, supporting CFI interrogation, unlock bypass programming, and suspend/resume for both program and erase operations. Internal ECC operates transparently during read cycles without host intervention.

FAQ

Does S29GL064S90TFI013 support 8-bit data bus operation?

Yes. When the BYTE# pin is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, while DQ8–DQ15 are disabled. This mode maintains full command compatibility and preserves all protection and ECC features. The 16-bit mode remains active when BYTE# is high, and the device automatically adapts based on this signal level at power-up or reset.

What is the function of the WP#/ACC pin beyond write protection?

The WP#/ACC pin serves dual roles: at logic low, it enables hardware write protection of the first or last sector; when driven to 5.5 V (±0.3 V), it activates accelerated programming mode, reducing individual word programming time by up to 40%. This high-voltage feature is intended for production-line programming and requires external voltage control circuitry.

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 via command sequence. Once locked, no further erase or program operations are possible-even with valid unlock commands. It contains a factory-programmed 16-byte random electronic serial number accessible only through a specific CFI query, making it suitable for device identity binding and cryptographic key anchoring.

Is automatic ECC applied to all read operations?

Yes. Hardware ECC is enabled by default and operates transparently on every read access across the entire memory array. Single-bit errors are corrected in real time with no latency penalty or host intervention. The ECC status register (bit 15 of Status Register) indicates whether correction occurred during the last read, allowing diagnostics without disrupting normal operation.
