STPCI2HEYC - 133 MHz x86 Terminal SoC | STMicroelectronics
STMicroelectronics STPCI2HEYC is a 133 MHz x86-compatible PC system-on-chip designed for terminals, graphics controllers, and embedded display systems, supplied in a 516-pin plastic BGA package. It combines a 64-bit bus architecture, a 64-bit DRAM controller, an integrated SVGA graphics controller, a 135 MHz RAMDAC, a video scaler, a digital PAL/NTSC encoder, a video input port, a CRT controller, and a PCI master interface. The part is also identified as the STPC Atlas x86 system-on-chip and is categorized as an application-specific microcontroller with external program memory.
An x86-compatible system-on-chip is an integrated processor platform that consolidates a PC-compatible computing core and common peripheral controllers into one device. In the hierarchy of semiconductor solutions, STPCI2HEYC belongs to the x86 microprocessor family, within the broader embedded microprocessor and system-on-chip categories. Unlike a discrete industrial PC, a terminal-oriented SoC can consolidate graphics, video, memory control, and PCI host functionality into one high-pin-count package. This integration supports compact designs intended to drive displays, decode video, and communicate through a PCI-based system architecture.
The primary electrical and functional highlights include a stated operating frequency of 133 MHz, a 64-bit internal bus architecture, external program-memory support, and integrated legacy display and video functions. The SVGA controller, 135 MHz RAMDAC, scan converter, and three-line flicker filter are particularly relevant to CRT-based terminal designs. The digital PAL/NTSC encoder expands support for composite video, while the video input and scaler support multimedia signal routing. The PCI master interface allows the SoC to operate as a bus master in a wider embedded platform.
Technical selection is tightly coupled to legacy display architecture. The 516-BBGA package is large relative to modern mixed-signal and embedded processors, but it supports the extensive mixed-signal, memory, graphics, PCI, power, and ground connections expected from a PC-compatible terminal SoC. Designers must follow the manufacturer's pinout, reference design, power-supply requirements, memory configuration, and PCB layout guidance exactly. Because this package is not represented in the available SVG library and a complete verified 516-pin assignment is not supplied in the source data, no pin names or electrical limits have been inferred here.
Typical uses include industrial terminal controllers, point-of-sale terminals, digital signage controllers, set-top-style appliances, and embedded systems requiring an x86 software environment with integrated graphics and PCI host capability. Its 133 MHz clock reflects a legacy PC-compatible architecture rather than a modern high-performance embedded processor. The integrated graphics and video blocks can reduce the need for separate display adapters in purpose-built equipment, although the complete board still requires carefully designed memory, video output, synchronization, and bus interfaces.
The principal design consideration is that STPCI2HEYC is a highly application-specific legacy SoC rather than a general-purpose microcontroller. Board developers should preserve the reference platform's memory topology and signal timing, use supported external devices, and validate display compatibility before production. Procurement should also confirm availability, revision identity, and manufacturing status with the authorized distributor because the verified datasheet listing describes the component as obsolete. This page distinguishes documented capabilities from unavailable details and does not infer electrical characteristics or replacement parts that are not established by the supplied sources.
This page consolidates the verified distributor, manufacturer-datasheet-index, and cross-reference search information for STPCI2HEYC, including its documented x86, graphics, video, memory, PCI, package, frequency, and pricing facts. It also identifies the critical engineering data that remains unavailable, preventing unsupported assumptions about pin assignments, power rails, operating temperature, compliance, lifecycle, and direct drop-in replacements.
