Infineon Technologies S29GL064N90TFI073

Overview

S29GL064N90TFI073 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words × 16-bit, 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) for embedded boot code and firmware storage in networking routers and industrial controllers.

For engineers reviewing the S29GL064N90TFI073 datasheet, S29GL064N90TFI073 pinout, S29GL064N90TFI073 application, or S29GL064N90TFI073 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, flexible sector protection (Persistent/Password), and dual-mode data bus (16-bit or byte-wide via BYTE#).

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, enabling deterministic sector-level erasure without disturbing adjacent sectors. Its VersatileI/O™ control uses VIO (1.65–3.6 V) to independently set input/output voltage levels, decoupling interface logic from core VCC (2.7–3.6 V).

The command-set architecture supports CFI compliance for automatic device identification, plus suspend/resume for both program and erase operations-allowing concurrent read access to unprotected sectors during background flash operations. Hardware features include RESET#, RY/BY#, and WP#/ACC pins for system-level control and accelerated factory programming.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90TFI073?

The WP#/ACC pin serves dual roles: as WP# (Write Protect), it locks the first or last sector against accidental erase/program when pulled low; as ACC (Accelerated Program), it accepts 5.0 V to reduce programming time during high-throughput manufacturing. The function depends on voltage level and command context-not external circuitry-and is internally decoded by the device state machine.

Does S29GL064N90TFI073 support byte-wide data access?

Yes, it supports 8-bit data access via the BYTE# input pin. When BYTE# is asserted low, the device operates in x8 mode using DQ0–DQ7 only, with A0–A20 providing addressing. This maintains full 64 Mbit capacity while enabling compatibility with legacy 8-bit microcontrollers and reducing PCB routing complexity.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by the user. Once secured, no further writes or erases are possible-even under elevated voltage or command override. It contains an 8-word electronic serial number (ESN) and is accessed only via a specific unlock sequence, making it suitable for storing immutable cryptographic keys or device identifiers.

Can S29GL064N90TFI073 be used in systems with 1.8 V I/O interfaces?

Yes, provided VIO is supplied at 1.65–3.6 V and VCC at 2.7–3.6 V. The VersatileI/O™ architecture decouples I/O buffer voltage from core logic voltage, allowing direct connection to 1.8 V microcontrollers while maintaining full 3.3 V internal operation. No level-shifting circuitry is required, simplifying interface design and reducing BOM cost.
