Programmable Switch Mode Controller (PSMC)

The PSMC is a high performance 16-bit PWM with 6 configurable outputs that can operate in multiple modes. With a dedicated 64MHz clock and the flexibility to interface to external inputs as well as integrated peripherals / clock sources, the PSMC offers the highest level of advanced PWM control and accuracy in an 8-bit MCU. The PSMC can simplify the implementation of a wide array of applications such as: motor control, lighting, and power supplies.

Features

  • 16-bit PWM with up to 6 configurable outputs
