GENERAL DESCRIPTION

This data sheet details the specific properties of the PCF84C12A, PCF84C22A and PCF84C42A. The shared properties of the PCF84CxxxA family of microcontrollers are described in the “PCF84CxxxA family” data sheet, which should be read in conjunction with this publication. Note that the devices described in this data sheet do not feature I2C-bus compatibility or derivative logic, so the information given in the family data sheet about these features can be ignored.
