Infineon Technologies S29GL128P10FFI010

Overview

S29GL128P10FFI010 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only 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 100 ns random access time under regulated VCC conditions. 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 controllers requiring nonvolatile firmware storage with sector-level protection.

For engineers reviewing the S29GL128P10FFI010 datasheet, S29GL128P10FFI010 pinout, S29GL128P10FFI010 application, or S29GL128P10FFI010 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function pin behavior for both acceleration and sector write protection.

Technical Context

This device implements a synchronous command-set architecture with embedded algorithms for program and erase operations, supporting suspend/resume functionality to enable background read during active programming or erasing. Its VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with mixed-voltage systems while maintaining full 16-bit data bus operation in word mode or 8-bit in byte mode via BYTE# input.

The internal block diagram includes dedicated erase/program voltage generators, state control logic with command register, and sector switching matrix enabling independent sector locking via persistent bits or password-based Advanced Sector Protection. Ready/Busy# (RY/BY#) provides real-time status feedback without polling overhead, and unlock bypass mode reduces single-word programming time to 60 µs.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability nonvolatile memory and microcontroller solutions for industrial, automotive, and communications markets, with emphasis on security, longevity, and mixed-signal integration.

The S29GL-P series was engineered specifically for embedded systems needing deterministic boot performance, field-upgradable firmware, and hardware-enforced data protection - targeting applications where legacy parallel NOR Flash remains preferred over SPI alternatives due to bandwidth and execution-in-place requirements.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10FFI010?

The WP#/ACC pin serves dual roles: at VIL (≤0.8 V), it protects the highest or lowest address sector from program/erase operations; at VHH (11.5–12.5 V), it enables unlock bypass mode, accelerating single-word programming to 60 µs and eliminating command sequence overhead during high-volume manufacturing. Internal pull-up ensures default VIH state when unconnected.

Does S29GL128P10FFI010 support execute-in-place (XIP) operation?

Yes - its asynchronous parallel interface and fast 100 ns random access time enable direct code execution from flash without copying to RAM. The device supports standard SRAM-compatible timing (CE#, OE#, WE#), allowing seamless integration with ARM Cortex-M or PowerPC host processors using XIP-capable memory controllers.

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, accessible only via specific command sequences. It contains an 8-word electronic serial number that can be permanently locked at factory or by customer - preventing readback or modification even with full physical access, unlike standard sectors which remain fully readable and erasable.

Can S29GL128P10FFI010 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ explicitly supports VIO = 1.65–VCC, so 1.8 V VIO with 3.3 V VCC is within specification. All address, control, and data pins reference VIO for logic thresholds, enabling direct connection to 1.8 V FPGAs or ASICs without level translators, while core memory array operates at optimal 3.3 V for endurance and retention.
