Infineon Technologies S29GL064N11TFIV73

Overview

S29GL064N11TFIV73 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 × 16-bit words, featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates in industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage for industrial controllers.

For engineers reviewing the S29GL064N11TFIV73 datasheet, S29GL064N11TFIV73 pinout, S29GL064N11TFIV73 application, or S29GL064N11TFIV73 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, flexible sector protection modes (Persistent and Password), and dual-voltage I/O support via VIO (1.65–3.6 V).

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, enabling byte/word-level random access and true in-system reprogrammability. Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy host firmware and standard Flash controllers.

The integrated VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing interface voltage scaling independent of internal logic. Sector erase architecture supports concurrent suspend/resume operations-enabling read or program access to unprotected sectors during active erase or program cycles-without compromising data integrity.

FAQ

What is the function of the WP#/ACC pin on S29GL064N11TFIV73?

The WP#/ACC pin serves dual roles: as WP# it permanently protects the first or last sector from accidental erase/program when pulled low; as ACC it accepts elevated voltage (typically 5.5 V) during manufacturing to accelerate programming throughput. This pin is not used for normal operation under 3.0 V supply and must be tied to VSS or VCC depending on desired protection behavior.

Does S29GL064N11TFIV73 support both x8 and x16 data bus configurations?

Yes. The device operates in x16 mode by default. When BYTE# is asserted low, DQ15 functions as A-1 and the device switches to x8 mode, using DQ0–DQ7 as the data bus. This dual-mode capability allows seamless integration with 8-bit or 16-bit microcontrollers without external glue logic or bus multiplexing.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at the factory with a unique 8-word electronic serial number (ESN). Once locked-either at factory or by customer-it becomes permanently read-only and immune to erase or program commands. Unlike standard sectors, it cannot be unlocked or modified, providing immutable device identity for secure boot and anti-cloning.

Can S29GL064N11TFIV73 be used in systems with 1.8 V I/O interfaces?

Yes. By applying 1.8 V to the VIO pin while maintaining VCC at 3.0 V (2.7–3.6 V), all input thresholds and output drive levels conform to 1.8 V logic standards. This eliminates external level shifters when interfacing with 1.8 V FPGAs or ASICs, preserving signal integrity and reducing PCB complexity in mixed-voltage designs.
