Infineon Technologies S29GL128P10TFI020

Overview

S29GL128P10TFI020 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 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 32-word write buffer and secured silicon sector with electronic serial number, and targets embedded boot code storage in industrial control systems.

For engineers reviewing the S29GL128P10TFI020 datasheet, S29GL128P10TFI020 pinout, S29GL128P10TFI020 application, or S29GL128P10TFI020 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), TSOP-56 package compatibility, VIO-configurable I/O voltage, and CFI-compliant interface for bootloader firmware storage in resource-constrained edge devices.

Technical Context

This device implements a synchronous/asynchronous hybrid command-set architecture with dedicated state control logic, internal voltage generators for erase/program operations, and hardware-based sector protection via persistent bits and password methods. Its block diagram reveals separate X/Y decoders, sector switching matrix, and RY/BY# status output tied directly to embedded algorithm completion detection.

The VersatileI/O™ control enables independent VIO supply (1.65–VCC) to set input thresholds and output drive levels, while the 8-word page read buffer and 32-word write buffer operate under distinct timing constraints-page access optimized for burst reads, write buffer reducing effective programming time per word to 13.5 µs with VHH acceleration.

FAQ

What is the maximum operating temperature range for S29GL128P10TFI020?

The S29GL128P10TFI020 is rated for industrial temperature range: –40°C to +85°C. This specification is confirmed in the Ordering Information section (Page 4) and Electrical Specifications (Page 50) of the official datasheet (Doc # 002-00886 Rev. *B). The 'I' suffix in the part number explicitly denotes industrial grade, and thermal derating is not required within this range.

Does S29GL128P10TFI020 support both word and byte configurations?

Yes, it supports both configurations via the BYTE# input pin. When BYTE# is driven low, the device operates in byte mode: DQ0–DQ7 are active, and DQ15/A-1 functions as address bit A-1. When BYTE# is high, it operates in word mode with DQ0–DQ15 active. This dual-mode capability is documented in Section 2 (Input/Output Descriptions) and enables flexible integration with 8-bit or 16-bit microcontrollers.

How does the WP#/ACC pin function in normal operation versus programming mode?

In normal operation, WP#/ACC must be held at VIH to enable standard read/write functions. When pulled to VIL, it protects the highest or lowest sector (configurable via model number). During programming, applying VHH (12 V) to WP#/ACC accelerates write operations and automatically enters unlock bypass mode - a feature verified in Section 1 (General Description) and Section 2 (Input/Output Descriptions) of the datasheet.

Is the secured silicon sector pre-programmed or user-programmable?

The secured silicon sector is user-programmable and lockable either at the factory or by the customer. It contains 128 words (256 bytes), including an 8-word (16-byte) electronic serial number field that can be written once and permanently locked. This capability is detailed in Section 1 (Distinctive Characteristics) and Section 10 (Secured Silicon Sector Flash Memory Region) of the datasheet, confirming field-programmability without requiring special test equipment.
