What are the differences between the types of Silicon Labs C8051F12x series Microcontrollers?

The C8051F12x series of microcontrollers from Silicon Labs are available in a variety of packages and feature sets. The main differences between the various types of C8051F12x microcontrollers are the amount of on-chip memory, the number of I/O pins, the number of timers, the number of analog-to-digital converters, and the type of on-chip oscillator. The C8051F120 and C8051F121 have the most on-chip memory, the most I/O pins, and the most timers, while the C8051F122 and C8051F123 have fewer I/O pins and fewer timers. The C8051F124 and C8051F125 have the most analog-to-digital converters, while the C8051F126 and C8051F127 have fewer analog-to-digital converters. The C8051F120, C8051F122, and C8051F124 all feature an on-chip oscillator, while the C8051F121, C8051F123, C8051F125, and C8051F127 all feature an external oscillator.
