Frequently Asked Questions
What is the minimum supply voltage for the PIC18LF4620-I/PT and what clock frequency does it support at that voltage?
The PIC18LF4620-I/PT operates from a minimum supply voltage of 2V, running at up to 4 MHz clock frequency in that low-voltage condition. When supplied from 3.3V or 5V sources, the device supports its full 20 MHz clock rate, providing design flexibility for systems transitioning between battery-powered low-power modes and higher-performance active states.
How many ADC channels does the PIC18LF4620 provide, and what types of sensors can be connected directly?
The PIC18LF4620 integrates a 10-bit ADC with multiple input channels shared with the GPIO pins. This allows direct connection to resistive sensors, thermistors, potentiometers, current sense resistors via shunt amplifiers, and ratiometric pressure sensors referenced to the supply voltage. The 10-bit resolution provides 1,024 distinct levels, enabling measurements with approximately 0.1% full-scale accuracy when the voltage reference is stable.
For a battery-operated data logger using PIC18LF4620, what sleep current reduction techniques are available?
The PIC18LF4620 supports multiple low-power modes including Sleep mode where the CPU stops and most peripherals are halted, reducing supply current to microamp levels from a 3V supply. The device can be woken by external interrupts, a watchdog timer, or peripheral events such as a completed ADC conversion, enabling duty-cycle operation with active periods as short as a few milliseconds per second and extending battery life to months or years on a pair of AA alkaline cells.
What communication peripherals are integrated in the PIC18LF4620-I/PT and how do they support multi-device systems?
The PIC18LF4620-I/PT includes USART, SPI, and I2C hardware peripherals supporting common embedded communication protocols. The USART enables RS-232 and RS-485 connections to host systems or other nodes, SPI supports high-speed communication with external flash memory, DACs, and display controllers at rates up to several MHz, and I2C at 400 kHz allows connection to sensors, EEPROMs, and real-time clocks on a shared 2-wire bus, covering most multi-device embedded system architectures.
