Infineon Technologies S29GL256P10FFI023

Overview

S29GL256P10FFI023 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology. It delivers 100 ns random access time and 25 ns page access time, features a 32-word/64-byte write buffer, uniform 64 Kword sectors (256 total), and supports CFI for host compatibility - deployed in industrial embedded controllers requiring nonvolatile program storage with sector-level protection.

For engineers reviewing the S29GL256P10FFI023 datasheet, S29GL256P10FFI023 pinout, S29GL256P10FFI023 application, or S29GL256P10FFI023 equivalent, key selection criteria include VIO-compatible I/O voltage scaling (1.65–VCC), hardware WP#/ACC acceleration, Secured Silicon Sector with factory-programmable ESN, and 100,000 erase cycles per sector with 20-year data retention.

Technical Context

This device implements a synchronous command-set architecture with VersatileI/O™ control: all address, control, and data I/O levels are referenced to VIO (1.65–VCC), enabling interoperability with mixed-voltage SoC interfaces. It supports both word (DQ0–DQ15) and byte (DQ0–DQ7 + A-1) configurations via BYTE# input.

Embedded algorithms manage program and erase operations with suspend/resume capability, status reporting via RY/BY# and internal status bits, and dual-sector protection methods - persistent lock bits and password-based Advanced Sector Protection - ensuring robust firmware integrity in field-deployed systems.

FAQ

What is the function of the VIO pin on the S29GL256P10FFI023?

The VIO pin sets the reference voltage for all address, control, and data I/O signals (1.65 V to VCC). This allows the device to interface directly with 1.8 V, 2.5 V, or 3.3 V host processors without level shifters, while maintaining full 2.7–3.6 V VCC operation for core memory functions.

Does the S29GL256P10FFI023 support hardware reset during active programming?

Yes. Asserting RESET# asynchronously halts any ongoing program or erase operation, clears internal state machines, and returns the device to reading array data mode. All status bits reset, and RY/BY# goes high-Z within tRC (100 ns max), enabling safe recovery from power faults or watchdog timeouts.

How is sector protection implemented on this device?

It uses two independent methods: persistent protection bits (nonvolatile lock bits per sector, set via command sequence) and password-based Advanced Sector Protection (software-controlled, requiring valid password entry before unlock). WP#/ACC provides additional hardware-level protection for top/bottom sectors regardless of software settings.

Can the Secured Silicon Sector be reprogrammed after factory locking?

No. Once the Secured Silicon Sector is permanently locked (via factory or user command), its contents-including the 8-word Electronic Serial Number-become read-only and cannot be altered. Unlocking requires physical device replacement; the lock bit itself is one-time programmable and irreversible.
