Infineon Technologies S29GL064N90FAI010

Overview

S29GL064N90FAI010 from Cypress Semiconductor is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 × 16-bit words, featuring 90 ns access time, 25 ns page read time, and 100,000 erase cycles per sector. It supports uniform or boot-sector architecture with 128 × 64 KB sectors or 127 × 64 KB + 8 × 8 KB boot sectors, and is used in embedded boot code storage for industrial controllers and network edge devices.

For engineers reviewing the S29GL064N90FAI010 datasheet, S29GL064N90FAI010 pinout, S29GL064N90FAI010 application, or S29GL064N90FAI010 equivalent, key selection factors include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware WP#/ACC input for accelerated programming and first/last sector protection.

Technical Context

This device implements a 16-bit wide data bus with BYTE# control enabling optional 8-bit operation, and uses hot-electron injection for programming and hot-hole assisted erase at the sector level. Its VersatileI/O™ architecture ties all input/output voltage thresholds to VIO (1.65–3.6 V), decoupling I/O logic from core VCC (2.7–3.6 V).

The command-set architecture supports Program Suspend/Resume and Erase Suspend/Resume, allowing concurrent read operations during active program or erase cycles. Status reporting is implemented via DQ7 Data# Polling, DQ6/DQ2 toggle bits, and dedicated RY/BY# output - all compliant with JEDEC Standard JESD21-C.

FAQ

Is S29GL064N90FAI010 compatible with standard JEDEC Flash command sets?

Yes. The device implements the JEDEC Standard JESD21-C command set for single-power-supply Flash, including autoselect, sector erase, chip erase, and program commands. It supports CFI query mode for automatic host identification and is software-compatible with earlier AMD/Spansion and Cypress parallel NOR Flash families.

What is the function of the WP#/ACC pin, and how does it differ from standard WP#?

The WP#/ACC pin serves dual roles: as Write Protect (low-active) to lock the first or last sector, and as Accelerated Program input (high-voltage enabled) to reduce programming time. Unlike basic WP#, it operates independently of sector protection settings and remains active during accelerated programming - a feature optimized for high-volume manufacturing throughput.

Does S29GL064N90FAI010 support both x8 and x16 data bus widths?

Yes. Using the BYTE# input, the device configures its data interface: BYTE# = HIGH selects 16-bit mode (DQ0–DQ15 active); BYTE# = LOW selects 8-bit mode (DQ0–DQ7 active, with DQ8–DQ15 unused). Address A-1 is multiplexed on DQ15 in x16 mode, eliminating need for an extra address line.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is pre-programmed at the factory with a unique 8-word (16-byte) Electronic Serial Number and can be permanently locked by the customer using the Persistent Sector Protection command sequence. Once locked, no further writes or erases are possible - even with elevated VPP - ensuring immutable device identity for secure boot and anti-counterfeiting applications.
