STPCC5HEBC

Application Specific Microcontrollers Overview

The STPCC5HEBC is an obsolete System-on-Chip from the STPC Consumer-II family, integrating a 32-bit x86 processor core with a 64-bit SDRAM controller and graphics subsystem. It operates at up to 100 MHz (x1) or 133 MHz (x2) with a unified memory architecture supporting 2 MB to 128 MB of system memory. The device includes a 135 MHz RAMDAC for SVGA displays, PCI/ISA controllers, EIDE interface, and video pipeline capabilities. Packaged in a 388-pin Plastic Ball Grid Array (PBGA), it was designed for consumer-oriented PC-compatible appliances.

Application Specific Microcontrollers Applications

• Consumer-oriented PC compatible information appliances
• All-in-one multimedia systems requiring integrated graphics and video processing
• Embedded PC platforms utilizing Unified Memory Architecture

Application Specific Microcontrollers Part Context

The STPCC5HEBC belongs to the STPC Consumer-II series, which consolidates traditional PC chipset functions into a single die. This specific suffix denotes an upgraded version within the family that includes errata fixes compared to earlier STPCC4 variants. Both versions maintain pin-to-pin compatibility but differ in supported software features and internal logic corrections.

Application Specific Microcontrollers Replacement Considerations

This component is marked as obsolete. No direct public substitute part numbers are documented in the source material. Designers must evaluate legacy support constraints or consider modern SoC architectures with comparable x86 and graphics integration capabilities.
