Product details
Overview
S29GL064N90DAI022 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words (8,388,608 bytes), featuring 90 ns access time, 16-bit data bus with BYTE#-enabled 8-bit mode, and uniform sector architecture with 128 × 64 KB sectors. It serves as nonvolatile program/data storage in embedded boot code, firmware update, and industrial control systems.
For engineers reviewing the S29GL064N90DAI022 datasheet, S29GL064N90DAI022 pinout, S29GL064N90DAI022 application, or S29GL064N90DAI022 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, hardware reset (RESET#), Ready/Busy# status signaling, and VIO-controlled VersatileI/O™ for mixed-voltage system interfacing.
Technical Context
This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, supporting both page read (8-word buffer, 25 ns page access) and buffered write (16-word buffer). Sector erase granularity enables selective reprogramming without disturbing adjacent sectors.
It integrates Advanced Sector Protection with Persistent and Password modes, CFI compliance for host auto-configuration, and hardware features including WP#/ACC-accelerated programming, automatic sleep mode, and low-VCC write inhibition. The RY/BY# output and DQ6/DQ7 polling provide real-time operation status feedback during erase/program cycles.

FAQ
What is the function of the WP#/ACC pin on S29GL064N90DAI022?
The WP#/ACC pin serves two distinct roles: when held low, it enables hardware write protection for the first or last sector regardless of software protection settings; when driven to VCC + 2.5 V (typically 5.5 V), it activates accelerated programming mode to reduce write time during high-volume manufacturing. This dual functionality eliminates need for external voltage switching circuitry in production test fixtures.
Does S29GL064N90DAI022 support 8-bit data interface?
Yes - the BYTE# input pin selects bus width: when BYTE# is low, the device operates in 8-bit mode using DQ0–DQ7, with DQ15 functioning as A-1; when BYTE# is high, it operates in full 16-bit mode. This allows seamless integration into both 8-bit microcontroller systems and 16-bit DSP-based platforms without external data bus multiplexing.
How is the Secured Silicon Sector protected and accessed?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at factory with an 8-word (16-byte) random Electronic Serial Number. Access requires issuing the Enter Secured Silicon Sector command sequence (0x555→0x2AA→0x555→0x55→0x2AA→0x70); once entered, reads return ESN data, and writes are permanently disabled even after power cycles or resets.
Can S29GL064N90DAI022 be used in systems with 1.8 V I/O logic?
Yes - the VIO pin accepts 1.65–3.6 V, allowing direct connection to 1.8 V logic families. When VIO = 1.8 V, all input thresholds and output drive levels conform to 1.8 V specifications, eliminating level shifters. However, VCC must remain within 2.7–3.6 V to ensure proper core operation and erase/program voltage generation.
