Infineon Technologies S29GL128P10FFIS12

Overview

S29GL128P10FFIS12 from Cypress Semiconductor is a 128 Mbit (16 MB) single-supply 3.0 V page-mode Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword (128 Kbyte) 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, 32-word write buffer, and secured silicon sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial embedded boot code storage and firmware update modules.

For engineers reviewing the S29GL128P10FFIS12 datasheet, S29GL128P10FFIS12 pinout, S29GL128P10FFIS12 application, or S29GL128P10FFIS12 equivalent, key selection criteria include sector architecture uniformity, VIO voltage flexibility, WP#/ACC dual-function pin behavior, CFI compliance, and industrial temperature operation (–40°C to +85°C) in Fortified BGA package.

Technical Context

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

The memory array uses a 128 Kbyte sector erase granularity and supports both byte- and word-width configurations via BYTE# control. Sector protection employs persistent lock bits and password-based methods, while Secured Silicon Sector provides tamper-resistant identity storage independent of main array operations.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FFIS12?

The WP#/ACC pin serves two distinct roles: at VIL (≤0.65 V), it protects the highest- or lowest-address sector from accidental writes; at VHH (11.5–12.5 V), it accelerates programming throughput by enabling unlock bypass mode. Internal pull-up ensures default VIH state when unconnected, preventing unintended lockout during power-up.

Does S29GL128P10FFIS12 support CFI (Common Flash Interface)?

Yes, the device fully complies with JEDEC Standard JESD68-A for Common Flash Interface. It exposes standardized CFI query data at address 0x55, enabling automatic detection of geometry, timing, and protection features by host BIOS or bootloader - eliminating hardcoded memory parameters in firmware.

How many address lines does S29GL128P10FFIS12 require?

S29GL128P10FFIS12 requires 23 address lines (A22–A0) to access its full 128 Mbit capacity. A22 is the most significant bit; A0 is the least significant. The device does not use A23–A25, which are marked NC on this variant per datasheet Figure 4.1.

Can S29GL128P10FFIS12 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ allows VIO to be set independently within 1.65 V to VCC. With VCC = 3.3 V, VIO may be 1.8 V, enabling direct interface to 1.8 V microcontrollers without level shifters. All input thresholds and output drive strengths scale dynamically with VIO, maintaining signal integrity across mixed-voltage systems.
