Overview

The H4T, or Hamilton Hallmark Hand Held Terminal Reference Design was developed as a working system to enable shorter design cycles by providing a proven plat-form as a starting point. The H4T was designed by Hamilton Hallmark with Intel support and highlights the features of the embedded Intel386(TM) EX processor and Intel boot block Flash memory. The H4T is available as a reference design kit which contains all necessary technical documentation; the design can be used "as is" or as a building block to enhance a specific solution. Handheld terminal applications are typically characterized by palm-sized portable devices for specific uses. These vertical applications include portable POS, dataloggers, barcode scanners, communicators, and organizers that are used in a variety of high utility environments, including retail, service, warehouses, inventory control, shipping, package delivery, manufacturing, hospitals, law enforcement, and many others. In general, software applications for handheld terminals have become more and more standardized on a PC-like environment with operating systems such as DOS; these applications can readily be developed on any PC systems with off-the-shelf tools.

Intel386 EX Processor

The Intel386 EX embedded processor is a highly integrated, 32-bit fully static CPU optimized for embedded control applications. With a 16-bit external data bus, a 26-bit external address bus, and Intel's System Management Mode (SMM), the Intel386 EX brings the vast software library of the Intel architecture to embedded systems. It provides the performance benefits of 32-bit programming with the cost savings associated with 16-bit hard-ware systems. The Intel386 EX processor integrates many peripheral blocks in a single chip as shown below.
