Infineon Technologies S29GL128P90TFIR10

Overview

S29GL128P90TFIR10 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, featuring 90 ns random access time, 25 ns page access time, and uniform 64 Kword (128 Kbyte) sector architecture with 128 sectors. It supports VersatileI/O™ (VIO = 1.65–VCC), write buffer programming (32-word/64-byte), and secured silicon sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial-grade embedded boot code storage for network routers.

For engineers reviewing the S29GL128P90TFIR10 datasheet, S29GL128P90TFIR10 pinout, S29GL128P90TFIR10 application, or S29GL128P90TFIR10 equivalent, key selection criteria include 90 ns read timing under regulated VCC, TSOP-56 industrial temperature support (–40°C to +85°C), WP#/ACC acceleration input for production programming throughput, and CFI-compliant interface for standardized flash management firmware.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with dedicated state control logic, erase voltage generator, and PGM voltage generator enabling embedded algorithms for sector erase and buffer programming. Its block diagram confirms separate X/Y decoders, sector switches, and RY/BY# status output tied directly to internal timer and algorithm completion detection.

The VersatileI/O™ control scheme decouples I/O voltage (VIO) from core supply (VCC), allowing DQ and control signal levels to scale independently across 1.65–VCC while maintaining full compatibility with 16-bit or 8-bit bus configurations via BYTE# input. Sector protection employs both persistent lock bits and password-based software methods, with hardware WP#/ACC providing dual-role sector lockout and VHH-accelerated programming.

FAQ

What is the function of the WP#/ACC pin on S29GL128P90TFIR10?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.8 V), it protects the highest or lowest address sector from accidental program/erase; at VHH (11.5–12.5 V), it enables unlock-bypass mode and accelerates single-word programming to 13.5 µs. Internal pull-up ensures safe default VIH state when unconnected.

Does S29GL128P90TFIR10 support byte-wide data access?

Yes - asserting BYTE# = VIL configures the device for 8-bit operation: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input. This mode is fully supported across all operating voltages and timing modes, including page read and write buffer programming.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region physically isolated from main array; it can be permanently locked at factory or by user to store an 8-word electronic serial number. Once locked, its contents cannot be erased or rewritten - providing tamper-resistant device identification for traceability and anti-cloning.

Can S29GL128P90TFIR10 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ explicitly supports VIO = 1.65–VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, allowing direct interface to 1.8 V logic families without external level shifters. All inputs (address, control, DQ) and outputs conform to 1.8 V thresholds when VIO = 1.8 V.
