Product Details

These components are available in 40/44 and 28-pin packages. There is no Parallel Slave Port (PSP) implemented in the 28-pin devices, and there are only 5 channels available for Analog-to-Digital (A/D) converter input.

The "RC" and "RCIO" device choices provide further cost reductions for applications that are not timing-sensitive. The supply voltage, the values of the resistors (REXT) and capacitors (CEXT), as well as the operating temperature, all influence the RC oscillator frequency. The oscillator frequency will also vary from unit to unit as a result of typical process parameter change.
