Infineon Technologies S29GL128P90FFIR22

Overview

S29GL128P90FFIR22 from Cypress Semiconductor is a 128 Mbit (16 MB) single-supply 3.0 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology. It delivers 90 ns random access time, 25 ns page access time, and features a 32-word (64-byte) write buffer for accelerated multi-word programming-ideal for boot code storage and firmware updates in industrial controllers and network edge devices.

For engineers reviewing the S29GL128P90FFIR22 datasheet, S29GL128P90FFIR22 pinout, S29GL128P90FFIR22 application, or S29GL128P90FFIR22 equivalent, key selection criteria include uniform 64 Kword sector architecture (128 sectors), 100,000 erase cycles per sector, 20-year data retention, VersatileI/O™ support (VIO = 1.65–VCC), and hardware reset (RESET#) with Ready/Busy# status signaling.

Technical Context

This device operates exclusively in single 3.0 V supply mode (2.7–3.6 V), with all I/O voltage levels referenced to the independent VIO pin-enabling flexible interfacing with 1.8 V, 2.5 V, or 3.3 V host systems. Its architecture supports byte/word configuration via BYTE# input and integrates CFI (Common Flash Interface) for standardized driver compatibility.

Embedded algorithms handle program and erase operations with suspend/resume capability, while status bits (via RY/BY# and internal flags) provide real-time operation feedback. Sector protection employs both persistent lock bits and password-based methods, and the Secured Silicon Sector provides factory- or customer-programmable 128-word electronic serial number.

FAQ

What is the function of the VIO pin on S29GL128P90FFIR22?

The VIO pin sets the voltage reference for all input thresholds and output drive levels-including address, control, and data signals. It operates from 1.65 V to VCC, enabling direct interface with 1.8 V, 2.5 V, or 3.3 V host processors without external level shifters. This decouples I/O logic compatibility from the core 3.0 V supply (VCC), simplifying mixed-voltage system design.

Does S29GL128P90FFIR22 support hardware reset during active programming?

Yes. The active-low RESET# input forces immediate termination of any ongoing program or erase operation and returns the device to read mode. This is essential for fault recovery in safety-critical systems. After reset, the device requires a minimum 100 ns delay before issuing new commands, and status bits reflect the aborted state until cleared by subsequent commands.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at the factory or by the user. Once locked, its contents-including an 8-word electronic serial number-are immune to erase or program commands. Unlike standard sectors, it cannot be unlocked or modified after final lock, providing hardware-enforced uniqueness and tamper resistance for device authentication.

Can S29GL128P90FFIR22 operate with VCC = 2.7 V and VIO = 1.8 V simultaneously?

Yes. The datasheet explicitly permits VIO = 1.65 V to VCC, and VCC = 2.7–3.6 V. At VCC = 2.7 V, VIO may be set to 1.8 V-enabling reliable communication with 1.8 V FPGAs or ASICs while maintaining sufficient VCC margin for stable internal charge pump operation during programming and erase cycles.
