Infineon Technologies S29GL064N90FFI012

Overview

S29GL064N90FFI012 from Infineon Technologies (formerly Cypress) is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory IC with uniform sector architecture (128 × 64 KB sectors), 90 ns access time, and 16-bit data bus. It serves as nonvolatile program/data storage in embedded boot code, firmware update, and configuration memory applications requiring JEDEC-compliant command-set compatibility and hardware write protection.

For engineers reviewing the S29GL064N90FFI012 datasheet, S29GL064N90FFI012 pinout, S29GL064N90FFI012 application, or S29GL064N90FFI012 equivalent, key selection criteria include sector erase flexibility, Secured Silicon Sector with factory-programmed 128-word ESN, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), and hardware reset (RESET#) support for system boot recovery.

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted sector erase, enabling byte/word-level random read and page-write (16-word buffer) with full sector-erase granularity. Its command register-based control logic supports CFI-compliant host identification and software-controlled Advanced Sector Protection modes.

The dual-voltage I/O interface (VIO separate from VCC) allows independent scaling of input/output signal levels while maintaining 3.0 V core operation. Hardware features include WP#/ACC-accelerated programming, RY/BY# status signaling, and automatic sleep mode triggered by address stability or CE#/RESET# assertion.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90FFI012?

The WP#/ACC pin serves dual roles: when held low, it hardware-protects the first or last sector against accidental erase/program; when driven to accelerated voltage (typically 5.5 V), it reduces programming time by enhancing electron injection efficiency. This dual functionality supports both field safety and factory throughput optimization without external circuitry.

Does S29GL064N90FFI012 support x8 data bus mode?

Yes, it supports x8 mode via the BYTE# input: when BYTE# is asserted low, the device operates as an 8-bit wide memory with DQ0–DQ7 active, while DQ8–DQ15 are tri-stated. This mode is fully compatible with legacy 8-bit microcontrollers and reduces signal count on space-constrained PCBs without sacrificing density.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at the factory with a unique 8-word electronic serial number. Once locked via command sequence, it becomes permanently read-only and immune to erase commands - unlike standard sectors, it cannot be reprogrammed or cleared, providing immutable device identity for licensing and anti-cloning.

Can S29GL064N90FFI012 be used in systems with mixed 1.8 V and 3.3 V I/O domains?

Yes, because its VIO pin accepts 1.65–3.6 V independently of VCC (2.7–3.6 V). Setting VIO = 1.8 V configures all inputs to recognize 1.8 V logic thresholds and outputs to drive 1.8 V-compatible levels, enabling direct interfacing with 1.8 V FPGAs or ASICs while maintaining 3.0 V core operation for reliability and speed.
