GENERAL DESCRIPTION

The ST6369 microcontroller is member of the 8-bit HCMOS ST638xfamily, a series of devicesspecially oriented to Digital Controlled Multi Frequency Monitor applications. ST6369 members are based on a building block approach: a common core is surrounded by a combination of on-chip peripherals (macrocells)available from a standardlibrary. These peripherals are designed with the same Core technology providing full compatibility and short design time. Many of these macrocells are specially dedicated to DCMF Monitor applications.
