The KamCho microcontroller family is a product line consisting of highly integrated 32-bit general purpose ARM M0 based microcontrollers, clocking at up to 20MHz.
KamCho-3Pb integrates 160kB of flash RAM and 8kB of SRAM on die for feature-rich applications or those requiring redundancy of data storage. It integrates multiple clocking options including a high accuracy (1%) 12MHz RC oscillator, 32kHz real-time clock, low power (<1uA) 10kHz auxiliary clock, and watchdog timer for high performance, low power designs.
This line of microcontroller product also integrates multiple peripherals. KamCho-3P is the 3-port version and the lowest cost product in the family. It has 24 general purpose I/O available to the user. Of these I/O ports, 8 have the capability to drive high current for LED applications.
The iND81203 also integrates an 8-bit ADC (SAR architecture) with up to 24 input channels. There is also a bandgap reference on die which supports the temperature sense circuit.
