Infineon Technologies S29GL512P12FFIV20

Overview

S29GL512P12FFIV20 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 (128 KB) sector architecture (512 sectors), and 32-word write buffer for accelerated multi-word programming. It operates across –40°C to +85°C and is used in industrial embedded boot code storage and firmware update storage.

For engineers reviewing the S29GL512P12FFIV20 datasheet, S29GL512P12FFIV20 pinout, S29GL512P12FFIV20 application, or S29GL512P12FFIV20 equivalent, key selection criteria include VersatileI/O™ voltage range (1.65–VCC), CFI compliance, Secured Silicon Sector with programmable 128-word serial number, suspend/resume capability, and WP#/ACC dual-function pin behavior under VHH acceleration.

Technical Context

This device implements a synchronous command-set architecture with autoselect, page read, and unlock-bypass programming modes. Its state machine supports concurrent erase-suspend and program-suspend operations, with RY/BY# output signaling algorithm completion and status bits reporting program/erase progress.

The 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 systems while maintaining full 2.7–3.6 V VCC operation. Sector protection employs both persistent lock bits and password-based Advanced Sector Protection.

FAQ

What is the function of the WP#/ACC pin on S29GL512P12FFIV20?

The WP#/ACC pin serves two distinct roles: at VIL, it protects the highest or lowest sector (configurable by model number) from accidental program/erase; when driven to VHH (12 V), it enables Unlock Bypass Program mode, reducing single-word programming time from 60 µs to 13.5 µs and accelerating production throughput.

Does S29GL512P12FFIV20 support true simultaneous read-while-write operation?

No - it supports suspend/resume, not true concurrent operation. During an active erase or program cycle, a read command will suspend the algorithm, return requested data, then automatically resume the background operation. This provides deterministic latency for time-critical reads without data corruption.

How is the Secured Silicon Sector programmed and locked?

The 128-word Secured Silicon Sector is programmed using standard CFI commands (e.g., Word Program) and locked permanently via the "Program Secured Silicon Sector Lock Bit" command. Once locked, the sector becomes read-only and immune to erase or further programming - even after power cycles or RESET# assertion.

What is the significance of the "V2" suffix in the part number S29GL512P12FFIV20?

The "V2" indicates VersatileI/O™ configuration with VIO = 1.65–VCC and lowest-address sector protection. This means the device accepts I/O voltages down to 1.65 V independent of VCC (2.7–3.6 V), and WP# at VIL disables program/erase in the first sector (A0–A15 range), protecting boot code stored at the lowest memory addresses.
