Infineon Technologies S29GL256P11FAIV22

Overview

S29GL256P11FAIV22 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 256 uniform 128 Kbyte sectors, 25 ns page access time, and 110 ns random access time under regulated VCC (3.0–3.6 V). It integrates a 32-word/64-byte write buffer, VersatileI/O™ control (VIO = 1.65–VCC), and secured silicon sector with factory-programmable 16-byte electronic serial number - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL256P11FAIV22 datasheet, S29GL256P11FAIV22 pinout, S29GL256P11FAIV22 application, or S29GL256P11FAIV22 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function pin behavior for production acceleration and sector protection.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, supporting byte/word configuration via BYTE# input and VersatileI/O voltage scaling to decouple I/O logic levels from core VCC. Its internal state machine handles embedded program/erase algorithms, with RY/BY# output signaling operation completion and suspend/resume capability for real-time interrupt handling.

The 90 nm MirrorBit architecture enables single-transistor storage per bit with charge-trap technology, delivering higher density and lower power versus floating-gate NOR. Sector protection uses persistent lock bits and password-based Advanced Sector Protection, while the secured silicon sector provides tamper-resistant identity storage independent of main array operations.

FAQ

What is the function of the WP#/ACC pin on S29GL256P11FAIV22?

The WP#/ACC pin serves dual roles: at VIL, it protects the highest or lowest address sector from program/erase operations; at VHH (12 V), it accelerates programming by enabling 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 S29GL256P11FAIV22 support byte-wide data access?

Yes - the BYTE# input selects bus width: when pulled low, DQ0–DQ7 are active and DQ15/A-1 becomes the LSB address input for 8-bit operation; when high, DQ0–DQ15 operate as a 16-bit word bus. This enables compatibility with both 8-bit and 16-bit microcontroller interfaces without external glue logic.

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

The Secured Silicon Sector is a physically isolated 256-byte region with separate lock mechanism - once programmed and locked (factory or customer), its contents cannot be erased or rewritten even with global erase commands. It stores a permanent 16-byte electronic serial number used for device authentication and anti-counterfeiting in certified systems.

Can S29GL256P11FAIV22 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O specification explicitly supports VIO = 1.65–VCC, so 1.8 V VIO with 3.3 V VCC is fully compliant. All address, control, and data pins reference VIO for logic thresholds, enabling direct connection to 1.8 V FPGAs or ASICs without level translators while maintaining full 3.3 V core performance.
