Infineon Technologies S29GL128P10FFIS10

Overview

S29GL128P10FFIS10 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Flash memory fabricated on 90 nm MirrorBit process technology, featuring uniform 64 Kword (128 Kbyte) sector architecture with 128 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/64-byte write buffer, and integrates Secured Silicon Sector for factory- or customer-programmable 128-word electronic serial number - deployed in industrial embedded controllers requiring reliable nonvolatile storage with fast firmware updates.

For engineers reviewing the S29GL128P10FFIS10 datasheet, S29GL128P10FFIS10 pinout, S29GL128P10FFIS10 application, or S29GL128P10FFIS10 equivalent, key selection criteria include its 64-ball Fortified BGA (LAA064) package, industrial temperature range (–40°C to +85°C), Pb-free compliance, 100,000 erase cycles per sector, and support for CFI, suspend/resume, and dual-sector protection methods (Persistent and Password).

Technical Context

This device operates as a parallel-interface NOR Flash memory with word/byte configuration selectable via BYTE# input, supporting both standard and page read modes (8-word/16-byte read buffer). Its command-set architecture enables autoselect, program/erase status polling via RY/BY#, and unlock bypass programming for throughput acceleration.

The integrated VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with mixed-voltage systems (e.g., 1.8 V I/O with 3.3 V core). Hardware reset (RESET#) and write protect/acceleration (WP#/ACC) inputs provide deterministic initialization and production-line programming enablement at VHH.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FFIS10?

The WP#/ACC pin serves two distinct roles: at VIL, it protects the highest or lowest sector from accidental program/erase; at VHH (12 V), it accelerates programming throughput by enabling unlock bypass mode. It has an internal pull-up, so it defaults to VIH (inactive protection) when left unconnected. This dual functionality supports both field safety and high-volume manufacturing programming.

Does S29GL128P10FFIS10 support execute-in-place (XIP) operation?

Yes - its 90 ns random access time and 25 ns page access time meet typical XIP timing requirements for ARM Cortex-M and PowerPC-based controllers. The device supports standard asynchronous read protocols with CE#, OE#, and WE# control, enabling direct instruction fetch from flash without copying to RAM, provided system bus timing aligns with tACC and tOE specifications.

How many address lines does S29GL128P10FFIS10 require?

S29GL128P10FFIS10 requires 23 address lines (A22–A0) to access its full 128 Mbit capacity. A22 is the MSB for sector selection; A0 is the LSB for word addressing within a 16-bit data bus. In byte mode (BYTE# = VIL), A-1 becomes active as the LSB address for 8-bit access, while DQ15/A-1 functions as A-1 rather than data.

Is the Secured Silicon Sector user-programmable and lockable?

Yes - the 128-word Secured Silicon Sector can be programmed and permanently locked either at the factory or by the end customer using standard command sequences. Once locked, the contents (including the 8-word electronic serial number) become read-only and immune to erase commands. Unlocking requires physical device replacement, ensuring irreversible identity binding for anti-counterfeiting and license enforcement.
