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.
- 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 ofall code
- External ISP Flash support for easy code download
- Dynamic Bus Sizing – each of 6 Chip Selects can be programmed for 8-bit or 16-bit bus.
- 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
