The world's smallest MCU, the C8051T606 provides a high degree of functional density for programmable embedded systems in a tiny 2x2 mm² footprint. The high-performance CPU enables greater design flexibility, and the integration of a voltage monitor and precision oscillator make the T606 ideal for space-constrained applications such as portable consumer products and accessories, gateways, and LED lighting.

The T606 offers higher levels of performance and integrated on-chip hardware peripherals giving customers design flexibility while reducing system complexity and cost. For example, the hardware implementation of I²C and UART on-chip leaves valuable code space for customer application code unlike competing solutions that require a software implementation of these features, wasting code space and CPU MIPs. An integrated 24.5 MHz precision internal oscillator and flexible UART baud rate generator allow UART communications over the full temperature and supply voltage range without the addition of a crystal. This saves cost, board space, and increases reliability.

Additionally, with a 25 MHz CPU, the T606 offers the highest level of processing power in its class, enabling real-time control, high-speed serial communication, fast interrupt servicing, and real time conversion between two different communications ports. The CPU combined with the programmable counter array (PCA) also allows a customer to implement proprietary and custom interface protocols without requiring an ASIC.

The T606's small footprint does not limit a customer's design flexibility; in fact, the high level of integrated functionality enables customers to also do the following:

• Implement UART-I²C bridges without relying on slower and less reliable software implementations.
• Perform brightness control, color mixing and thermal management required for LED lighting.
• Efficiently implement a system supervisor solution in applications that need warning of low power supply to safely shutdown or switch to battery backup. The T606's comparator has the unique capability to select multiple inputs with a software controlled multiplexer enabling it to monitor more than one voltage. The on-chip voltage supply monitor ensures the MCU is operating with sufficient supply voltage without the addition of an off-chip supervisor reducing the cost and footprint of the solution.
