Infineon Technologies S29GL064N11FFIV10

Overview

S29GL064N11FFIV10 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 both standard and accelerated programming via WP#/ACC input for factory throughput.

For engineers reviewing the S29GL064N11FFIV10 datasheet, S29GL064N11FFIV10 pinout, S29GL064N11FFIV10 application, or S29GL064N11FFIV10 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-identification, and dual-mode VIO (1.65–3.6 V) enabling flexible I/O voltage control independent of VCC.

Technical Context

This device uses 110 nm MirrorBit process technology to deliver high-density nonvolatile storage with hot-hole assisted erase and hot-electron injection programming. Its architecture includes separate CE#, WE#, and OE# controls, RY/BY# status output, and hardware RESET# for system-level boot recovery.

The S29GL064N11FFIV10 supports byte/word configuration via BYTE# input, Unlock Bypass mode (2-cycle programming), and concurrent operations via Program/Erase Suspend & Resume - enabling read access to unprotected sectors during active program or erase cycles.

FAQ

Is S29GL064N11FFIV10 compatible with legacy S29GL064N designs?

Yes - S29GL064N11FFIV10 maintains full pin, command-set, and timing compatibility with earlier S29GL064N variants. The "11F" speed grade denotes 90 ns access at VCC/VIO = 2.7–3.6 V, matching original spec; no PCB or firmware changes are required for drop-in replacement in existing designs.

What is the function of the WP#/ACC pin in normal operation versus programming mode?

In normal operation, asserting WP# low protects the first or last sector from accidental writes or erases. During programming, applying VHH (high voltage) to ACC enables accelerated programming - reducing single-word program time by ~30% and improving throughput in automated test equipment and system-level programming stations.

Does S29GL064N11FFIV10 support 8-bit data bus operation?

Yes - when BYTE# is driven low, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ15–DQ8 disabled. Addressing remains word-based internally, but the host accesses bytes sequentially; this mode enables compatibility with legacy 8-bit microcontrollers without external glue logic.

How is the Secured Silicon Sector protected and accessed?

The Secured Silicon Sector is permanently locked at factory or by customer via command sequence; once secured, no further writes or erases are possible. Access requires entering Secured Silicon Sector mode using a specific unlock command, then reading the 128-word region - including the 8-word electronic serial number - through standard DQ lines under VIO-controlled logic levels.
