Infineon Technologies S29GL128P10FAI012

Overview

S29GL128P10FAI012 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword sectors, 25 ns page access time, and 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, includes a 32-word write buffer for accelerated multi-word programming, and integrates Secured Silicon Sector with factory- or customer-programmable 8-word Electronic Serial Number - deployed in industrial embedded boot code storage.

For engineers reviewing the S29GL128P10FAI012 datasheet, S29GL128P10FAI012 pinout, S29GL128P10FAI012 application, or S29GL128P10FAI012 equivalent, key selection criteria include sector erase endurance (100,000 cycles), 20-year data retention, 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 command-set architecture with autoselect, suspend/resume, and unlock bypass modes. Its internal state machine handles embedded program/erase algorithms, while RY/BY# provides real-time status feedback without polling. The 8-word page read buffer enables burst-access efficiency in boot loader fetch sequences.

VersatileI/O™ decouples I/O voltage (VIO) from core supply (VCC), allowing interface compatibility with 1.8 V, 2.5 V, or 3.3 V controllers while maintaining 3.0 V core operation. Sector protection uses persistent lock bits and password methods, with WP#/ACC enabling both hardware write protection and VHH-accelerated programming during manufacturing.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FAI012?

The WP#/ACC pin serves two distinct roles: at VIL, it hardware-protects the highest or lowest sector (configurable via model number); at VHH (12 V), it enables Unlock Bypass mode and accelerates programming throughput by ~25%. Internal pull-up ensures safe default VIH state when unconnected, preventing accidental protection activation during power-up.

Does S29GL128P10FAI012 support byte-wide data access?

Yes - when BYTE# is driven low, the device operates in byte mode: DQ7–DQ0 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This enables direct connection to 8-bit microcontrollers without external data bus multiplexing, preserving pin count and simplifying PCB routing.

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 logic. It supports one-time programmable 8-word Electronic Serial Numbers and can be permanently locked at factory or by end-user. Unlike standard sectors, it cannot be erased after locking and is inaccessible via standard command sequences unless explicitly enabled.

Can S29GL128P10FAI012 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ allows VIO to be set between 1.65 V and VCC. With VCC = 3.3 V, VIO may be independently supplied at 1.8 V, enabling direct interfacing with 1.8 V FPGAs or ASICs while maintaining full 3.3 V core performance, including 25 ns page access and 100,000 erase cycle endurance.
