UART RECEIVER WITH ADAPTIVE SAMPLE TIMING CONTROL USING A NUMERICALLY-CONTROLLED OSCILLATOR

Abstract:

A system includes a battery and a monitoring circuit coupled to the battery. The monitoring circuit includes a sense circuit and a peripheral device coupled to the sense circuit. The peripheral device includes a universal asynchronous receiver-transmitter (UART) receiver having an adaptive sample timing circuit with a numerically-controlled oscillator (NCO) circuit. The peripheral device also includes memory coupled to the UART receiver and configured to store battery monitoring data.
