Product details

Overview

S29GL064N90TFA023 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It implements uniform sector architecture with 128 × 64 KB sectors and supports boot code storage in embedded systems requiring nonvolatile program storage.

For engineers reviewing the S29GL064N90TFA023 datasheet, S29GL064N90TFA023 pinout, S29GL064N90TFA023 application, or S29GL064N90TFA023 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), and support for Erase/Program Suspend & Resume in real-time firmware update scenarios.

Technical Context

This device uses 110 nm MirrorBit process technology to enable high-density NOR Flash with simultaneous hot-hole erase and hot-electron programming. Its command-set compliance with JEDEC JESD21-C ensures interoperability with legacy 3V flash controllers without hardware redesign.

The dual-voltage I/O architecture (VIO = 1.65–3.6 V, VCC = 2.7–3.6 V) decouples input/output logic levels from core supply, enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V microcontrollers. The Ready/Busy# (RY/BY#) output and DQ6/DQ7 status reporting provide deterministic timing control for interrupt-driven firmware operations.

Key Specifications

FAQ

Is S29GL064N90TFA023 pin-compatible with earlier S29GL064N variants?

Yes - the 'TFA023' suffix denotes a specific 48-pin TSOP packaging variant with standard JEDEC MO-141AC footprint and identical pinout to all S29GL064N models in TSOP48. Mechanical dimensions, solder pad layout, and signal assignments match exactly, enabling drop-in replacement in existing PCB designs.

Does this device support 8-bit data bus operation?

Yes - when the BYTE# input is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0–A20 providing 21-bit addressing. This mode is fully supported in both read and program operations and maintains full command-set compatibility including CFI queries and sector protection commands.

What is the function of the WP#/ACC pin during normal operation?

When held high, WP#/ACC enables accelerated programming via internal voltage boosting, reducing typical program time by ~3×. When pulled low, it hardware-protects the first or last sector regardless of software protection settings - a critical feature for safeguarding boot vectors in safety-critical systems.

How is the Secured Silicon Sector programmed and locked?

The 128-word Secured Silicon Sector is pre-programmed with a unique 8-word Electronic Serial Number at the factory and permanently locked using a one-time fuse. Customer programming is possible only before final lock; once locked, no read, write, or erase access is permitted - verified by dedicated command sequences and hardware fuse state detection.
