Infineon Technologies S29GL064N11TFIV23

Overview

S29GL064N11TFIV23 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 supports uniform sector architecture with 128 × 64 KB sectors and operates in industrial temperature range (–40°C to +85°C), deployed in boot code storage for embedded controllers and firmware update modules.

For engineers reviewing the S29GL064N11TFIV23 datasheet, S29GL064N11TFIV23 pinout, S29GL064N11TFIV23 application, or S29GL064N11TFIV23 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, VersatileI/O™ voltage flexibility (VIO = 1.65–3.6 V), and hardware-accelerated programming via WP#/ACC pin.

Technical Context

This device implements a command-set-compatible, single-supply NOR Flash architecture with hot-electron injection programming and hot-hole assisted sector erase. It integrates CFI (Common Flash Interface) for host auto-identification and supports both byte- and word-wide configurations via BYTE# control.

Its dual-bus operation enables 8-word page read buffer (25 ns page access) and 16-word write buffer, while hardware features include RY/BY# status output, RESET# reset input, and low-VCC write inhibit. Sector protection combines Persistent and Password-based methods, with Secured Silicon Sector locked at factory or by user.

FAQ

What is the function of the WP#/ACC pin on S29GL064N11TFIV23?

The WP#/ACC pin serves dual roles: when held low, it hardware-locks the first or last sector regardless of software protection settings; when pulsed high (≥VCC + 0.5 V), it enables accelerated programming for reduced factory burn-in time. This pin is electrically isolated from VCC and must be driven with appropriate voltage translation circuitry if interfaced to 1.8 V logic.

Does S29GL064N11TFIV23 support byte-wide data access?

Yes, it supports 8-bit operation via the BYTE# input: when BYTE# is low, DQ0–DQ7 function as an 8-bit data bus with DQ15 acting as A-1 for address extension; when BYTE# is high, the device operates in full 16-bit mode. This dual-width capability eliminates need for external data bus multiplexing in mixed-interface systems.

How is the Secured Silicon Sector programmed and protected?

The Secured Silicon Sector is pre-programmed at factory with a unique 8-word (16-byte) Electronic Serial Number and can be permanently locked by issuing the Program Secured Silicon Sector command followed by the Sector Protect command. Once locked, no further writes or erases are possible-even under accelerated programming conditions-and the ESN remains readable throughout device life.

Can S29GL064N11TFIV23 be used in systems with 1.8 V I/O voltage?

Yes, provided VIO is supplied at 1.65–3.6 V independently of VCC (2.7–3.6 V). With VIO = 1.8 V, all input thresholds and output drive levels conform to 1.8 V logic families, enabling direct connection to FPGA or ASIC I/O banks without level shifters-confirmed in datasheet Section 15 AC Characteristics and Figure 1 pinout.
