Both the 2E, 2F and 2K, 2L groups are considered application focused. The 2E-2F was originally designed for lighting applications, while the 2K-2L was developed for motor control. Some of the unique features in the 2E-2F include the addition of a DAC and two independent analog comparators. Users can configure the DAC to be used as a reference voltage for the on-board analog comparators, providing a great level of resolution and stability. The output signal of the comparators can be used to generate an interrupt, which could trigger the operation of a timer unit, or can be routed directly to an external circuit. In the case of the R8C/2K-2L, the key highlight is the addition of an extra 16-bit timer. Timer RD is the most advanced 16-bit timer unit in the R8C family. It is capable of generating up to 6-channels of complimentary PWM signals with 16-bit resolution. It provides a programmable Dead-Time Control (also 16-bits of resolution) and optional buffer operation for fast timer reload. The PWM signals can also be disabled with no delay by using a shut-off pin. Additionally, the timer unit has an internal hardware connection to the A/D (analog to digital) converter for triggering requirements.
