Infineon Technologies S29GL128P90FFCR10

Overview

S29GL128P90FFCR10 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Mode Flash memory fabricated on 90 nm MirrorBit process technology, featuring 90 ns random access time, 25 ns page access time, and uniform 64 Kword (128 KB) sector architecture with 128 sectors. It supports VersatileI/O™ (VIO = 1.65–VCC), 32-word write buffer, and Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number. Used in industrial embedded systems for firmware storage and boot code retention.

For engineers reviewing the S29GL128P90FFCR10 datasheet, S29GL128P90FFCR10 pinout, S29GL128P90FFCR10 application, or S29GL128P90FFCR10 equivalent, key selection criteria include single-supply 3 V operation, BGA-64 package compatibility, 100,000 erase cycles per sector, 20-year data retention, and support for CFI-compliant host interfaces in space-constrained industrial controllers.

Technical Context

This device implements a synchronous/asynchronous hybrid command interface with dedicated RY/BY# status output and hardware RESET# input for deterministic recovery. Its VersatileI/O™ architecture decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V host logic while maintaining 3 V internal programming/erase voltages.

The 32-word write buffer enables burst programming of up to 64 bytes per command, reducing effective programming time by ~75% versus single-word writes; suspend/resume commands allow real-time interruption of erase or program operations without data loss or timing violation.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability non-volatile memory and microcontroller solutions for industrial, automotive, and communications infrastructure markets.

The S29GL-P family targets embedded systems needing deterministic boot performance, long-term data integrity, and hardware-enforced security - specifically engineered for mission-critical firmware storage where software-based protection is insufficient.

FAQ

What is the maximum operating frequency supported for continuous page reads?

The S29GL128P90FFCR10 supports up to 10 MHz for 8-word page read operations, delivering sustained throughput of 80 MB/s in burst mode. This is enabled by its internal 8-word read buffer and 25 ns page access time, independent of system clock - no external clock input is required as timing is controlled by CE# and OE# strobes.

How does the WP#/ACC pin function in production programming versus field operation?

In production, applying VHH (~11.5 V) to WP#/ACC activates unlock-bypass mode, eliminating command sequence overhead and reducing single-word programming time to 13.5 µs. In field operation, holding WP#/ACC at VIH maintains normal command-set behavior, while pulling it to VIL permanently protects the top or bottom sector from accidental erasure or overwrite.

Can the Secured Silicon Sector be reprogrammed after factory locking?

No - once the Secured Silicon Sector is permanently locked (via Program Lock command), its 128-word contents - including the 8-word electronic serial number - become read-only and immune to erase or program commands. Unlocking requires physical device replacement; this immutability is verified by Cypress's factory programming certification and documented in datasheet section 10.1.

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

Yes - the LAA064 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports peak reflow temperatures up to 260°C for 30 seconds. Cypress specifies a ramp rate ≤3°C/s and preheat soak at 150–200°C for 90–120 seconds; no special underfill or thermal relief is required for standard Type 3 solder paste.
