Frequently Asked Questions
What CAN protocol version does the PIC18LF66K80-I/PT support, and in which automotive applications is it commonly deployed?
The PIC18LF66K80-I/PT integrates an Enhanced CAN (ECAN) controller that supports CAN 2.0B protocol at standard and extended frame formats. It is commonly used in automotive body control modules, door modules, and seat adjustment controllers where a cost-effective 8-bit node needs to communicate at up to 1 Mbit/s on a shared CAN bus.
How does the 12-bit ADC resolution in the PIC18LF66K80-I/PT benefit sensor measurement accuracy compared to 10-bit ADC devices?
A 12-bit ADC provides 4,096 discrete levels versus 1,024 for a 10-bit ADC, yielding 4x finer resolution. For a 3.3 V reference, this corresponds to a step size of approximately 0.8 mV per LSB, enabling accurate measurement of small differential signals from pressure sensors, temperature transducers, or resistive dividers used in battery state-of-charge estimation.
Can the PIC18LF66K80-I/PT implement capacitive touch sensing without an external touch controller, and what is the CTMU module?
Yes, the PIC18LF66K80-I/PT includes a built-in Charge Time Measurement Unit (CTMU) that charges a capacitive electrode through a precision current source (typically 0.55 µA to 55 µA selectable) and measures the resulting charge time via the 12-bit ADC. This eliminates the need for a dedicated capacitive touch IC, reducing BOM cost in single-chip HMI panels with up to 16 touch buttons.
