The 8-bit PIC microcontrollers from Microchip Technology have an on-chip 16 MHz internal oscillator.

Microchip Technology Inc. (Chandler, AZ) [NASDAQ:  MCHP] has announced from the Embedded Systems Conference in Boston several new 8-bit PIC microcontrollers (MCUs) that feature:

• Configurable logic.
• A high level of peripheral integration in 6- to 20-pin packages. 
• Complementary Waveform Generators (CWGs).
• Numerically Controlled Oscillators (NCOs).
• Low power consumption, with currents of less than 30 µA/MHz in active mode, and less than 20 nA in sleep.
• An on-chip 16 MHz internal oscillator.
• Analog-to-Digital Converter (ADC).
• Up to 4 Pulse-Width Modulation peripherals.
