Product Overview

The Infineon (formerly Cypress) S29GL064N90TFI040 is a 64Mbit (8,388,608 bytes) parallel NOR Flash memory from the GL‑N family, designed for embedded systems requiring high‑performance code execution, fast random access, and long‑term reliability. Operating from a standard 2.7V to 3.6V supply, it features a 90ns access time, enabling zero‑wait‑state operation with many microprocessors and microcontrollers. The device offers a flexible interface with configurable x16 or x8 data bus width, selectable via the BYTE# pin.

The S29GL064N is organized as 67 main sectors (64KB each) plus 8 parameter sectors (4KB each), providing fine‑granularity erase for boot code and parameter storage. Housed in a standard 48‑pin TSOP I package (TFI040 suffix), it operates over the industrial temperature range of -40°C to +85°C. The "040" suffix indicates a specific packing option (typically tray packaging). With 100,000 program/erase cycles and 20‑year data retention, this device is ideal for automotive aftermarket, industrial control, networking equipment, and telecom infrastructure.

⚡ Parallel NOR Architecture & Read Performance

90ns Access Time

The device delivers a maximum random access time (tACC) of 90ns, enabling direct code execution (XIP) without wait states for many processors.

Read/Write Bank Architecture

Four independent banks allow concurrent operations: read code from one bank while updating firmware in another — eliminating system downtime.

Unlock Bypass Mode

Accelerated programming for sequential writes, reducing total programming time by eliminating command overhead for each word.

The S29GL064N is part of the GL family, which features a synchronous burst read mode (up to 33 MHz) and asynchronous page read mode (16‑word page), improving sustained read throughput for linear code execution.

🔒 Advanced Sector Protection & Security

🔐 Sector Locking
Each sector can be individually locked (write/erase protected) using the WP# pin and software control. The lock status can be programmed even when the WP# pin is active, providing flexible security.

🔑 Password‑Protected Program/Erase
Optional 64‑bit password protection prevents accidental or unauthorized write operations, ideal for secure boot code or configuration data.

📦 Secured Silicon Region (SSR)
A 16‑byte factory‑programmed OTP area (some variants include a 256‑bit secure ID) for permanent storage of unique serial numbers or encryption keys.

🛡️ Hardware Write Protection (WP#)
When WP# is driven low, the top or bottom sectors become write‑protected, safeguarding critical boot code without software intervention.
