Integrated circuit for an asynchronous serial data transfer with a bit length counter

An integrated circuit for transferring asynchronous serial data, comprising:

• a sampler configured to sample the asynchronous serial data with a sampling clock;
• a bit length counter configured to determine a bit clock by counting a number of predetermined clock cycles of a bit length counter clock, where a bit length terminal variably adjusts the number of predetermined clock cycles of the bit length counter;
• and
• an adjustable prescaler configured to receive the sampling clock and generate the bit length counter clock,
• wherein the bit length counter comprises an adjustable bit length counter,
• wherein the sampling clock and an adjustment parameter are applied to the adjustable prescaler to determine the number of predetermined clock cycles, and
• wherein the adjustable prescaler makes a bit time determinable for the bit length counter by counting a number of clock cycles of the bit length counter clock that is variably adjustable relative to the sampling clock.

A method for transferring asynchronous serial data of an integrated circuit, comprising the steps of:

• Sampling, by a sampler, the asynchrounous serial data with a sampling clock;
• Determining, by an adjustable bit length counter, a bit clock by counting a number of predetermined clock cycles of the sampling clock;
• variably adjusting, by a bit length terminal, the number of predetermined clock cycles of the bit length counter;
• and
• receiving a system clock, by an adjustable prescaler, to generate the sampling clock.
