DESCRIPTION
The powerful 16-bit XA CPU core and rich feature set makeFEATURES
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 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. Table 1. XA-H3 and XA-H4 features comparison Feature Maximum External Memory (Harvard Memory Mode) Maximum External Memory (Unified...
