The shared properties of the PCF84Cxxx A family of microcontrollers are described in the “PCD84xxx A family” data sheet which should be read in conjunction with this publication. The PCF84C85A is a general purpose CMOS microcontroller with emphasis on input/output. It provides 32 I/O port lines, 8 kbytes of program memory and 256 bytes of RAM. In addition to the 32 I/O port lines, the microcontroller provides an on-chip I2C-bus interface. This two-line serial bus extends the microcontroller's capabilities when...
