Product Summary

The powerful 16-bit XA CPU core and rich feature set make the
XA-H3 and XA-H4 devices ideal for high-performance real-time
applications such as industrial control and networking. By supporting
of up to 32 MB of external memory, these devices provide a low-cost
solution to embedded applications of any complexity. Features like
DMA, memory controller and four advanced UARTs help solve I/O
intensive tasks with a minimum of CPU load.
The XA-H3 feature set is a subset of the XA-H4 (see Table 1). The
XA-H3/H4 devices are members of the Philips XA (eXtended
Architecture) family of high performance 16-bit microcontrollers.
The XA-H3 and XA-H4 are designed to significantly minimize the
need for external components
