General Info

A total of up to 40 analog inputs are supported. Three high-speed 12-bit parallel ADC chips (AD7852) can be installed, each chip providing 8 channels analog inputs (for a total of 24 channels), with up to 300K samples per second.

The AD7852 includes sample-and-hold, a precision internal reference, and has an input range of 0-5 V. Two 16-bit ADC (ADS8344, TI) chips provides a total of 16 single-ended or 8 differential analog inputs (0-5V, or 0-REF) with 65536 counts of resolution and a max sample rate up to 10 KHz.

The RA features fast execution times through 80MHz 186 CPU, 16-bit Flash and 16-bit battery-backed SRAM. A 50-pin CompactFlash receptacle can be installed to allow access to mass storage CompactFlash cards (up to 1GB). Users can easily add mass data storage to their embedded application. FAT12/16 filesystem support is included within the software development package.

Three RS232 serial ports are available by default: a dual UART (SCC2692) and a single CPU internal UART(default as DEBUG port). All UARTs have deep FIFOs to minimize the potential of receiver overrun or to reduce interrupt overhead. The UART also incorporate 9-bit mode for multi-processor communications.

A single UART can be buffered by RS232 (as default), RS485, or RS422 (for an additional charge). 40+ TTL I/O lines are free to use, including 24 bi-directional I/Os from the PPI (82C55), 32 multifunctional CPU internal PIOs, and TTL I/Os from the DUART. A parallel DAC (DA7625, 5 ms, 4 ch, 12-bit, 0-2.5V) and 2 serial DACs (DAC7612, 2 ch, 12-bit, 0-4.095V) can be installed to support a total of up to 8 analog outputs.
