Infineon Technologies S29GL01GP11FFIR23

Overview

S29GL01GP11FFIR23 from Cypress Semiconductor (acquired by Infineon) is a 1 Gbit (128 Mbyte), 3.0 V-only, page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology. It delivers 110 ns random access time, 25 ns page access time, and features a 32-word/64-byte write buffer, uniform 64 Kword sectors (1024 total), and Secured Silicon Sector with factory-programmable 8-word Electronic Serial Number. It is used in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL01GP11FFIR23 datasheet, S29GL01GP11FFIR23 pinout, S29GL01GP11FFIR23 application, or S29GL01GP11FFIR23 equivalent, key selection criteria include its 64-ball Fortified BGA (LAA064) package, industrial temperature range (–40°C to +85°C), VersatileI/O™ support (VIO = 1.65–VCC), CFI compliance, and hardware-accelerated programming via WP#/ACC at VHH.

Technical Context

This device implements a synchronous-capable, non-volatile NOR architecture with embedded program/erase algorithms and status reporting via RY/BY# and status bits. Its VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V logic domains while maintaining 3.0 V-only core operation.

The 1 Gbit density is organized as 1024 uniform 64 Kword (128 Kbyte) sectors, supporting sector erase (0.5 s typical), suspend/resume for program/erase, and dual protection methods - persistent lock bits and password-based Advanced Sector Protection - ensuring robust firmware integrity in mission-critical applications.

FAQ

What is the function of the WP#/ACC pin in S29GL01GP11FFIR23?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.65 V), it protects the highest or lowest address sector from accidental program/erase; at VHH (11.5–12.5 V), it enables Unlock Bypass Program mode, accelerating single-word programming by skipping command sequences. Internal pull-up ensures safe default VIH state when unconnected.

Does S29GL01GP11FFIR23 support true XIP (eXecute-In-Place) operation?

Yes - its NOR architecture, fast random access (110 ns), and asynchronous interface allow direct code execution from the memory array without copying to RAM. This is confirmed by its use in boot ROM applications and support for CFI query tables that enable automatic memory mapping in bootloaders.

How is the Secured Silicon Sector programmed and locked?

The 256-byte Secured Silicon Sector is programmed using standard command sequences (e.g., Word Program command 0x40), then permanently locked via the Sector Lock-Down command (0x60 followed by 0xD0). Once locked, no further writes or erases are possible - even with VPP applied - ensuring immutable device identity and cryptographic key storage.

Can S29GL01GP11FFIR23 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ explicitly supports VIO = 1.65 V to VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, configuring all address, control, and data pins to recognize 1.8 V logic thresholds and drive 1.8 V-compatible outputs, enabling seamless interfacing with 1.8 V SoCs without level shifters.
