Product details
Overview
S29GL064N90TFI020 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 Secured Silicon Sector with factory-programmable 128-word Electronic Serial Number and supports boot-sector or uniform-sector architectures for embedded firmware storage in industrial controllers and network boot loaders.
For engineers reviewing the S29GL064N90TFI020 datasheet, S29GL064N90TFI020 pinout, S29GL064N90TFI020 application, or S29GL064N90TFI020 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), hardware reset (RESET#), Ready/Busy# status signaling, and dual-mode sector protection (Persistent + Password).
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole erase and hot-electron programming across 32 Kword (64 KB) sectors. Its architecture includes separate CE#, WE#, and OE# controls, a 16-word write buffer, and 8-word page read buffer - enabling high-throughput firmware updates and low-latency boot code fetches.
The S29GL064N90TFI020 supports both uniform-sector (128 × 64 KB) and boot-sector (127 × 64 KB + 8 × 8 KB) configurations. It integrates CFI (Common Flash Interface) for automatic device identification, Erase/Program Suspend & Resume for concurrent background operations, and hardware-level write protection via WP#/ACC and RESET# pins.
Key Specifications

FAQ
Is S29GL064N90TFI020 compatible with legacy Cypress S29GL064N designs?
Yes - this part retains identical electrical specifications, pinout, command set, and timing parameters as the original Cypress S29GL064N90TFI020. Infineon maintains full backward compatibility, including identical AC/DC characteristics and CFI descriptor structure, ensuring seamless drop-in replacement without design revision.
What is the function of the WP#/ACC pin in normal operation versus programming mode?
In normal operation, asserting WP# (low) hardware-locks the first or last sector regardless of software protection settings. During programming, applying 5.5 V to ACC accelerates write throughput by ~3×; the pin senses voltage level internally to auto-select mode - no external switching required.
Does S29GL064N90TFI020 support 8-bit data bus operation?
Yes - when BYTE# is driven low, the device operates in x8 mode using DQ0–DQ7 only; A-1 is disabled, and DQ15 becomes NC. This mode maintains full addressability and command compatibility, enabling use with 8-bit microcontrollers without external data bus multiplexing.
How is the Secured Silicon Sector programmed and locked?
The 128-word Secured Silicon Sector is programmed via dedicated command sequence (Enter Secured Silicon Sector mode → Write data → Lock command). Once locked via PPB bit, it becomes permanently read-only - even after power cycles or device reset - and cannot be erased or rewritten without factory intervention.
