Infineon Technologies S29GL128P10TFI0205

Overview

S29GL128P10TFI0205 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 25 ns page access time, 90 ns random access time, and uniform 64 Kword (128 KB) sector architecture with 128 sectors. It supports VersatileI/O™ control (VIO = 1.65–VCC), 32-word write buffer, and Secured Silicon Sector with 128-word electronic serial number for secure device identification in embedded boot code storage.

For engineers reviewing the S29GL128P10TFI0205 datasheet, S29GL128P10TFI0205 pinout, S29GL128P10TFI0205 application, or S29GL128P10TFI0205 equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), TSOP-56 package compatibility, CFI compliance, Advanced Sector Protection (persistent/password), and WP#/ACC dual-function pin behavior for factory programming acceleration and hardware write protection.

Technical Context

This NOR Flash device implements a synchronous command-set architecture with autoselect, page read, and unlock-bypass programming modes. Its internal state machine handles embedded erase and program algorithms, while RY/BY# provides real-time status feedback without polling. The VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V logic systems.

It features hardware reset (RESET#) for safe power-up initialization, BYTE# pin for dynamic word/byte configuration, and dedicated WP#/ACC pin that enables VHH-accelerated programming during production or locks outermost sectors when pulled low. Sector erase endurance is rated at 100,000 cycles with 20-year data retention under industrial conditions.

FAQ

What is the function of the WP#/ACC pin on S29GL128P10TFI0205?

The WP#/ACC pin serves two distinct hardware functions: when held at VIL (≤0.65 V), it protects the highest or lowest sector from accidental program/erase; when driven to VHH (11.5–12.5 V), it accelerates programming throughput and automatically enters unlock-bypass mode, eliminating command overhead during high-volume manufacturing.

Does S29GL128P10TFI0205 support byte-wide data access?

Yes - the BYTE# pin controls bus width: when pulled low, the device operates in byte mode (DQ0–DQ7 active; DQ15/A-1 becomes A-1 address input); when high, it operates in word mode (DQ0–DQ15 active). This enables flexible integration with 8-bit or 16-bit microcontrollers without external glue logic.

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 can store an 8-word electronic serial number and is programmable/lockable either at factory or by end users. Once locked, its contents cannot be erased or rewritten, providing immutable device identity for traceability and anti-counterfeiting.

Can S29GL128P10TFI0205 be used in systems with 1.8 V I/O interfaces?

Yes - with VCC = 3.0–3.6 V and VIO = 1.65–VCC, the device fully supports 1.8 V logic signaling. Input thresholds track VIO, and output drive strength is optimized for 1.8 V CMOS loads, eliminating need for external level translators in mixed-voltage embedded systems.
