AD5570 to PIC16C6x/7x
EVALUATION BOARD
The PIC16C6x/7x synchronous serial port (SSP) is configured
as an SPI master with the clock polarity bit set to 0. This is done
by writing to the synchronous serial port control register
(SSPCON). See the PIC16/17 Microcontroller User Manual. In
The AD5570 comes with a full evaluation board to aid designers
in evaluating the high performance of the part with a minimum
of effort. All that is required with the evaluation board is a
power supply, a PC, and an oscilloscope.

The AD5570 evaluation kit includes a populated, tested AD5570
printed circuit board. The evaluation board interfaces to the
parallel interface of the PC. Software is available with the
evaluation board, which allows the user to easily program the
AD5570. A schematic of the evaluation board is shown in
Figure ꢁ5. The software runs on any PC that has Microsoft
Windows® 95/98/ME/ꢀ000 installed.
enable the serial port of the AD5570. This microcontroller
transfers only eight bits of data during each serial transfer
operation; therefore, two consecutive write operations are
needed. Figure ꢁꢁ shows the connection diagram.
