Infineon Technologies S29GL512P11FFI020

Overview

S29GL512P11FFI020 from Cypress Semiconductor is a 512 Mbit (64 MB) single-supply 3.0 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 100 ns random access time, uniform 64 Kword sectors (512 total), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL512P11FFI020 datasheet, S29GL512P11FFI020 pinout, S29GL512P11FFI020 application, or S29GL512P11FFI020 equivalent, key selection criteria include VIO-supported Versatile I/O voltage range (1.65–VCC), write buffer programming efficiency (32-word/64-byte burst), secured silicon sector with factory-programmable serial number, and CFI-compliant interface for host system compatibility.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with dedicated state control logic, embedded erase/program algorithms, and hardware-accelerated unlock bypass mode triggered via WP#/ACC at VHH. It supports byte/word configuration via BYTE# input and uses RY/BY# to signal algorithm completion without polling.

The memory array employs X/Y decoding with sector switching and integrated PGM/erase voltage generators, enabling deterministic timing for sector erase (0.5 s typical) and single-word programming (60 µs). Its CFI table resides in fixed address space and reports geometry, command sets, and protection methods to host BIOS or bootloader.

FAQ

What is the function of the VIO pin on S29GL512P11FFI020?

The VIO pin sets the voltage reference for all input thresholds and output drive levels, allowing I/O signaling to operate independently from VCC across 1.65 V to VCC. This enables direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic families without external level shifters, reducing BOM count and layout complexity in mixed-voltage SoC designs.

Does S29GL512P11FFI020 support simultaneous read and program operations?

No - it supports suspend/resume of program or erase operations to allow temporary read access, but cannot execute read and program concurrently. When suspend is issued during programming, the device halts the write sequence, responds to read commands, then resumes programming upon resume command - critical for real-time interrupt handling in RTOS environments.

How is the Secured Silicon Sector protected from accidental overwrite?

The Secured Silicon Sector is protected by a dedicated lock bit that, once programmed, permanently disables further writes to that 128-word region. Locking can be performed at factory or in-system using a specific command sequence; the lock bit itself is one-time programmable and irreversible, ensuring cryptographic keys or serial numbers remain tamper-proof throughout device life.

What packaging options are available for S29GL512P11FFI020?

S29GL512P11FFI020 is offered exclusively in the 64-ball Fortified BGA (LAA064) package, Pb-free (F), industrial temperature grade (I). The "F" in the part number explicitly denotes this BGA variant; TSOP-56 versions use "T" (e.g., S29GL512S11TFI020) and are distinct orderable SKUs with different mechanical and thermal characteristics.
