Infineon Technologies S29GL256P90FFCR12

Overview

S29GL256P90FFCR12 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, uniform 64 Kword sectors (256 total), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL256P90FFCR12 datasheet, S29GL256P90FFCR12 pinout, S29GL256P90FFCR12 application, or S29GL256P90FFCR12 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte burst), secured silicon sector with factory-programmable serial number, and CFI-compliant interface for host system compatibility.

Technical Context

This device implements a NOR Flash architecture with dual-bus X/Y decoding, integrated erase/program voltage generators, and state machine-controlled embedded algorithms. It supports byte/word configuration via BYTE# input, hardware reset (RESET#), and Ready/Busy# status signaling for asynchronous operation coordination.

The VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V logic domains while maintaining full 2.7–3.6 V VCC operation. Sector protection employs both persistent lock bits and password-based methods, with WP#/ACC serving dual roles: sector write protection at VIL and programming acceleration at VHH.

FAQ

What is the function of the VIO pin on the S29GL256P90FFCR12?

VIO sets the input/output voltage reference independently from VCC, allowing the device to interface directly with 1.65–3.6 V logic families without level shifters. It defines thresholds for all address, control, and data signals, enabling seamless integration into mixed-voltage systems such as those combining 1.8 V microcontrollers with 3.3 V power rails.

Does the S29GL256P90FFCR12 support true byte-wide operation?

Yes - the BYTE# input selects between word (16-bit) and byte (8-bit) configuration. When BYTE# is low, DQ0–DQ7 are active and DQ15/A-1 functions as the LSB address line, enabling compatibility with 8-bit processors and legacy designs requiring narrow data paths without external demultiplexing.

How is sector protection implemented on this device?

Sector protection uses two independent methods: persistent lock bits (nonvolatile, one-time programmable) and password-based unprotection (volatile until next power cycle). WP#/ACC provides hardware-level top/bottom sector protection at VIL, while software commands enable fine-grained sector locking/unlocking via CFI-defined registers.

Can the secured silicon sector be programmed after device shipment?

Yes - the 256-byte secured silicon sector can be programmed and locked either at the factory or by the end customer using standard CFI command sequences. Once locked, the contents (including the 16-byte electronic serial number) become permanently read-only and immune to erase or program commands.
