ORDERING INFORMATION
This data sheet details the specific properties of the
PCA84C44X, PCA84C64X and PCA84C84X.
The shared characteristics of the PCA84CXXX family of
microcontrollers are described in the PCF84CXXXA
Family single-chip 8-bit Microcontroller of
“Data Handbook
IC14”
, which should be read in conjunction with this data
sheet.
