Infineon Technologies S29GL128P90FFIR23

Overview

S29GL128P90FFIR23 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only Page Mode Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 90 ns random access time, 25 ns page access time, uniform 64 Kword (128 Kbyte) sector architecture (128 sectors), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL128P90FFIR23 datasheet, S29GL128P90FFIR23 pinout, S29GL128P90FFIR23 application, or S29GL128P90FFIR23 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte buffer), secured silicon sector with electronic serial number, CFI compliance, and industrial temperature range (–40°C to +85°C).

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# control lines, supporting byte/word configuration via BYTE# input and hardware reset via active-low RESET#. Its internal state machine manages embedded program/erase algorithms with suspend/resume capability and real-time status reporting via RY/BY# output.

The 64-ball Fortified BGA (LAA064) package enables high-density PCB layout while supporting dual VCC/VIO supply domains: VCC regulates core logic (2.7–3.6 V), and VIO sets I/O voltage level (1.65–VCC), allowing interoperability with 1.8 V, 2.5 V, or 3.3 V host interfaces without level shifters.

FAQ

What is the function of the VIO pin on S29GL128P90FFIR23?

The VIO pin sets the input threshold voltage and output drive level for all address, control, and data pins (A0–A22, CE#, OE#, WE#, DQ0–DQ15/A-1). It operates independently from VCC and ranges 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 - a key differentiator versus fixed-I/O NOR Flash devices.

Does S29GL128P90FFIR23 support both byte and word data configurations?

Yes. The BYTE# input determines bus width: when pulled low, the device operates in byte mode (DQ0–DQ7 active, DQ15/A-1 becomes A-1 address line); when high, it operates in word mode (DQ0–DQ15 active). This dual-mode capability allows seamless integration with 8-bit and 16-bit microcontrollers using the same footprint and firmware abstraction layer.

How does the Secured Silicon Sector work, and can it be programmed in-system?

The Secured Silicon Sector is a dedicated 256-byte region containing an 8-word (16-byte) Electronic Serial Number. It can be factory-programmed and permanently locked, or customer-programmed and locked via command sequence. Once locked, no further writes are possible - providing hardware-enforced uniqueness and anti-cloning protection for certified medical and industrial devices.

Is the 64-ball Fortified BGA (LAA064) package compatible with standard reflow profiles?

Yes, but with strict thermal limits: peak reflow temperature must not exceed 260°C for ≤30 seconds, and exposure above 150°C must be minimized to prevent internal delamination. Cypress specifies special handling instructions - ultrasonic cleaning is prohibited, and post-reflow X-ray inspection requires adjusted parameters to avoid damage to the fortified underfill structure.
