Product details
Overview
S29GL064N90DAI020 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 bits, 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 across VIO = 1.65–3.6 V for flexible I/O voltage control. Used in industrial embedded boot code storage and firmware update modules where reliable nonvolatile program storage is required.
For engineers reviewing the S29GL064N90DAI020 datasheet, S29GL064N90DAI020 pinout, S29GL064N90DAI020 application, or S29GL064N90DAI020 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), CFI compliance, and support for Program/Erase Suspend & Resume operations.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It features dual-voltage I/O control via VIO (1.65–3.6 V), independent of VCC (2.7–3.6 V), enabling interoperability with mixed-voltage host systems.
The command-set architecture is fully JEDEC JESD21C compliant and includes CFI tables for automatic device identification. Sector protection is enforced through lock registers, PPB bits, and password-protected write/erase inhibition - all implemented in hardware without external logic.

FAQ
What is the function of the WP#/ACC pin on S29GL064N90DAI020?
The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector regardless of software protection settings; when pulsed to 5.5 V (VCC + 2.5 V), it activates accelerated programming mode for faster factory programming. This dual functionality is electrically isolated - protection remains active even during ACC pulses, ensuring boot sector integrity during high-throughput production.
Does S29GL064N90DAI020 support 8-bit data bus operation?
Yes, the device supports 8-bit mode via the BYTE# input: when BYTE# is low, only DQ0–DQ7 are active as an 8-bit data bus, with DQ8–DQ15 tri-stated. Address lines remain unchanged, and all commands function identically. This mode is fully compliant with JEDEC standards and requires no timing adjustments - enabling drop-in replacement in legacy 8-bit microcontroller systems.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is pre-programmed at the factory with a unique 8-word (16-byte) Electronic Serial Number and can be permanently locked using the Persistent Sector Protection command sequence. Once locked, no further writes or erases are possible - even with valid passwords or ACC voltage. The lock is irreversible and verified by reading the PPB bit; unlocking requires physical device replacement.
Can S29GL064N90DAI020 be used in systems with 1.8 V I/O interfaces?
Yes, provided VIO is supplied at 1.8 V (within 1.65–3.6 V range) and VCC remains at 2.7–3.6 V. All input thresholds and output drive levels dynamically scale to VIO, enabling safe interfacing with 1.8 V FPGAs or microcontrollers. However, the device itself does not generate 1.8 V - external regulation of VIO is required; no level-shifting circuitry is needed.
