Infineon Technologies S29GL256P11FFIV23

Overview

S29GL256P11FFIV23 from Cypress Semiconductor is a 256 Mbit (32 MB) single-supply 3.0 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 256 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 110 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 electronic serial number - deployed in industrial embedded boot code storage and firmware update systems.

For engineers reviewing the S29GL256P11FFIV23 datasheet, S29GL256P11FFIV23 pinout, S29GL256P11FFIV23 application, or S29GL256P11FFIV23 equivalent, key selection criteria include sector architecture uniformity, VIO voltage flexibility, suspend/resume capability during erase/program, CFI compliance, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for real-time operation monitoring.

Technical Context

This device implements a synchronous-compatible asynchronous interface with dual-bus width support (word/byte mode via BYTE#), enabling flexible data path integration in microcontroller-based boot loaders. Its internal state machine handles autonomous program/erase algorithms, with status bits (DQ7, DQ6) reporting completion and error conditions without external polling overhead.

The 64-ball Fortified BGA (LAA064) package supports high-density PCB layouts and includes dedicated VIO supply for independent I/O voltage control, allowing interoperability with 1.8 V or 3.3 V host logic while maintaining core VCC at 3.0–3.6 V. Sector protection uses both persistent lock bits and password methods, with WP#/ACC serving dual roles: hardware write protection and VHH-accelerated programming.

FAQ

What is the function of the WP#/ACC pin on S29GL256P11FFIV23?

The WP#/ACC pin serves two distinct roles: at VIL, it hardware-protects the highest or lowest sector (configurable by model number); at VHH (12 V), it accelerates programming by automatically entering unlock bypass mode, reducing single-word programming time from 60 µs to 13.5 µs. Internal pull-up ensures safe default VIH state when unconnected.

Does S29GL256P11FFIV23 support byte-wide data access?

Yes, byte-wide access is supported via the BYTE# input: when driven low, DQ0–DQ7 become active data lines and DQ15/A-1 functions as the LSB address bit. This enables compatibility with 8-bit microcontrollers and reduces PCB routing complexity in space-constrained designs.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable 8-word electronic serial number. Once locked (via command sequence), its contents cannot be erased or rewritten - even during full-chip erase - providing immutable device identification essential for anti-counterfeiting and regulatory traceability.

Can S29GL256P11FFIV23 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the VersatileI/O™ architecture explicitly supports VIO from 1.65 V to VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, allowing direct interface to 1.8 V FPGAs or ASICs without external level translators - all address, control, and data signals conform to 1.8 V logic thresholds while core memory operates at 3.3 V.
