XA-H3
DESCRIPTION
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.
FEATURES
•
Large Memory Support (up to 6 MB external)
•
De-multiplexed Address/Data Bus
•
Six Programmable Chip Selects
–
Support for Unified Memory – allows easy user modification of
all code
–
External ISP Flash support for easy code download
•
Dynamic Bus Timing – each of 6 chip selects has individual
programmable bus timing.
•
32 Programmable General Purpose I/O Pins
•
Four UARTs with 230.4 kbps capability
•
Eight DMA Channels
•
Dynamic Bus Sizing – each of 6 Chip Selects can be programmed
for 8-bit or 16-bit bus.
