Infineon Technologies S29GL128P11FFIV13

Overview

S29GL128P11FFIV13 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 128 uniform 128 Kbyte sectors, 25 ns page access time, and 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector with factory-programmable 256-byte serial ID - deployed in industrial embedded controllers requiring nonvolatile program storage with sector-level protection.

For engineers reviewing the S29GL128P11FFIV13 datasheet, S29GL128P11FFIV13 pinout, S29GL128P11FFIV13 application, or S29GL128P11FFIV13 equivalent, key selection criteria include 128 Kbyte uniform sector architecture, 100,000 erase cycles per sector, 20-year data retention, WP#/ACC acceleration input for production programming, and CFI-compliant interface for bootloader compatibility.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with dedicated state control logic, embedded erase/program algorithms, and hardware-based sector protection via persistent lock bits and password methods. Its VersatileI/O™ design decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V host interfaces while maintaining 3.0 V core operation.

The block diagram confirms independent X/Y decoders driving a cell matrix with sector switches, integrated PGM/erase voltage generators, and RY/BY# status output tied directly to internal state machine completion signals - not software-polling dependent. RESET# provides hardware-initiated recovery to read mode without requiring command sequences.

FAQ

What is the function of the WP#/ACC pin on S29GL128P11FFIV13?

The WP#/ACC pin serves dual roles: at VIL, it protects the highest or lowest sector from accidental program/erase; at VHH (12 V), it enables Unlock Bypass mode for accelerated programming during manufacturing. It has an internal pull-up, so it defaults to VIH when unconnected - ensuring write protection unless actively overridden.

Does S29GL128P11FFIV13 support byte-wide data access?

Yes. When BYTE# is driven low, the device operates in byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This allows 8-bit microcontroller interfacing without external data bus multiplexing, preserving pin count and simplifying layout.

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

The Secured Silicon Sector is a dedicated 256-byte region with permanent lock capability: once locked (via factory or user command), its contents cannot be erased or reprogrammed. It contains an 8-word electronic serial number and supports cryptographic key storage - physically isolated from main array with separate protection logic.

Can S29GL128P11FFIV13 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes. The VersatileI/O™ specification explicitly permits VIO = 1.65 V to VCC, so 1.8 V I/O operation with 3.3 V core supply is fully supported. All address, control, and data signals conform to 1.8 V logic thresholds, enabling direct connection to low-voltage FPGAs or ASICs without level-shifting circuitry.
