Infineon Technologies S29GL512P10FFI020

Overview

S29GL512P10FFI020 from Cypress Semiconductor (acquired by Infineon) is a 512 Mbit (64 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 100 ns random access time, and uniform 64 Kword (128 KB) sector architecture with 512 sectors. It supports VersatileI/O™ control (VIO = 1.65–VCC), 32-word write buffer, and Secured Silicon Sector with factory-programmable 8-word Electronic Serial Number. Used in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL512P10FFI020 datasheet, S29GL512P10FFI020 pinout, S29GL512P10FFI020 application, or S29GL512P10FFI020 equivalent, key selection criteria include 100 ns random access timing under regulated VCC (3.0–3.6 V), 64-ball Fortified BGA (LAA064) package compatibility, industrial temperature range (–40°C to +85°C), and support for CFI, suspend/resume, and Advanced Sector Protection via persistent bits or password.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, enabling standard NOR Flash read/program/erase operations. Its VersatileI/O architecture decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V or 3.3 V logic while maintaining 3.0 V core operation.

The 32-word write buffer enables burst programming of up to 64 bytes per command, reducing effective programming time versus single-word writes. Embedded algorithms manage sector erase (0.5 s typical), unlock bypass, and status reporting via RY/BY# and internal status bits - all compliant with Common Flash Interface (CFI) query structure.

FAQ

What is the function of the WP#/ACC pin on S29GL512P10FFI020?

The WP#/ACC pin serves dual roles: at VIL (≤0.8 V), it protects the first or last sector from accidental program/erase; at VHH (11.5–12.5 V), it accelerates programming throughput and automatically enables Unlock Bypass mode. Internal pull-up ensures safe default (VIH) state when unconnected.

Does S29GL512P10FFI020 support byte-mode operation?

Yes - when BYTE# is driven low, the device operates in byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This enables 8-bit microcontroller interfacing without external data bus multiplexing.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region physically isolated from main array. It supports one-time programmable Electronic Serial Number (8 words) and can be permanently locked at factory or by customer - preventing overwrite even after full chip erase or power cycle.

Can S29GL512P10FFI020 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ explicitly supports VIO = 1.65–VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, allowing direct connection to 1.8 V logic families. All address, control, and data signals conform to 1.8 V thresholds, eliminating external level shifters in mixed-voltage designs.
