Frequently Asked Questions
How many ADC channels does the PIC18LF1220-I/SO provide, and what is their resolution?
The PIC18LF1220-I/SO includes 7 analog input channels, each resolved by a 10-bit ADC, giving 1024 quantization levels per conversion. This is suitable for reading sensors such as temperature, pressure, or light intensity in embedded designs.
What is the maximum clock frequency of the PIC18LF1220-I/SO and how does it affect power consumption?
The PIC18LF1220-I/SO can operate at up to 40 MHz. Running at reduced frequencies, such as 4 MHz or 8 MHz, significantly lowers dynamic current draw, which is important for battery-powered applications requiring extended operating life.
Is the PIC18LF1220-I/SO suitable for 3.3 V or 5 V systems, and what supply range does it support?
The LF suffix on PIC18LF1220-I/SO indicates low-voltage operation, with a supply range of 2.0 V to 5.5 V. This makes it compatible with both 3.3 V and 5 V systems, providing flexibility for mixed-voltage designs.
What memory resources does the PIC18LF1220-I/SO offer for firmware and runtime data?
The PIC18LF1220-I/SO provides 4 KB of Flash program memory for firmware storage and 256 bytes of on-chip data RAM for runtime variables. A separate EEPROM section of 256 bytes is also available for non-volatile data retention.
How does the 18-pin SOIC package of PIC18LF1220-I/SO compare to other form factors for board assembly?
The 18-pin SOIC package has a 1.27 mm pin pitch and a body width of approximately 7.5 mm, which is compatible with standard SMT reflow processes. It is easier to hand-solder than fine-pitch TQFP or QFN packages, making it practical for prototyping.
