Infineon Technologies S29GL128P90FFCR23

Overview

S29GL128P90FFCR23 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page 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 KB) 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 S29GL128P90FFCR23 datasheet, S29GL128P90FFCR23 pinout, S29GL128P90FFCR23 application, or S29GL128P90FFCR23 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte buffer), secured silicon sector with factory-programmable ESN, 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 RESET#. Its internal state machine executes embedded program/erase algorithms with suspend/resume capability and status reporting via RY/BY#.

The 64-ball Fortified BGA (LAA064) package supports VersatileI/O™ operation where VIO independently sets I/O voltage level (1.65–VCC) while VCC supplies core logic (2.7–3.6 V); WP#/ACC provides dual-mode functionality - sector protection at VIL and programming acceleration at VHH - enabling production-line throughput optimization.

Manufacturer

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

The S29GL-P series was engineered specifically for embedded systems demanding deterministic parallel NOR Flash performance, long-term data integrity, and secure firmware identity - targeting applications where SPI Flash lacks speed and NAND Flash lacks reliability.

FAQ

What is the function of the WP#/ACC pin on S29GL128P90FFCR23?

The WP#/ACC pin serves dual roles: at VIL (≤0.8 V), it protects the highest or lowest sector from program/erase commands; at VHH (11.5–12.5 V), it accelerates programming by enabling unlock-bypass mode, reducing single-word programming time from 60 µs to 13.5 µs. An internal pull-up ensures default VIH state when unconnected.

Does S29GL128P90FFCR23 support both byte and word data configurations?

Yes. The BYTE# input selects bus width: at VIL, DQ0–DQ7 are active (byte mode) and DQ15/A-1 becomes address A-1; at VIH, DQ0–DQ15 are active (word mode). This allows seamless integration with 8-bit or 16-bit microcontrollers without external glue logic.

How does the Secured Silicon Sector enhance system security?

The 256-byte Secured Silicon Sector contains a factory-programmable 16-byte Electronic Serial Number and supports customer locking. Once locked, contents cannot be altered - enabling tamper-resistant device identification, license binding, and secure boot chain anchoring in medical and industrial systems.

Can S29GL128P90FFCR23 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes. VersatileI/O™ allows VIO to be set independently from VCC within 1.65 V to VCC. With VCC = 3.3 V, VIO may be 1.8 V, enabling direct connection to 1.8 V I/O domains (e.g., FPGA banks or low-voltage MCUs) without level translators - verified per datasheet Section 7.3 and AC specs Table on Page 53.
