Frequently Asked Questions
How does PIC18F23K20-I/SS perform in a battery-powered sensor node running at reduced supply voltage?
The PIC18F23K20-I/SS operates down to 1.8 V supply while still running at up to 16 MHz, and at 2 V it reaches 20 MHz. This makes it suitable for single-cell Li-ion or 2× AA battery applications where the rail drops below 2.5 V during discharge, while the 10-bit ADC continues to acquire sensor data accurately across 10 input channels.
What analogue measurement capability does the PIC18F23K20-I/SS provide for multi-channel sensing designs?
The device integrates a 10-channel, 10-bit successive-approximation ADC capable of resolving signals to approximately 4.88 mV per LSB at a 5 V reference. This is sufficient for temperature, pressure, and current-sense applications, allowing a single chip to replace an external ADC and reduce BOM cost in data-acquisition systems.
What is the maximum clock frequency of the PIC18F23K20-I/SS and how does supply voltage affect it?
At 5 V supply the PIC18F23K20-I/SS reaches its maximum 64 MHz clock, while at 2 V the top speed drops to 20 MHz and at 1.8 V it is limited to 16 MHz. Designers should verify that timing-critical firmware loops account for this frequency derating when the board operates at the lower end of the 1.8 V to 5.5 V supply range.
For a compact motor-control design, what board space does the SSOP-28 package require compared to a DIP alternative?
The 28-pin SSOP package measures approximately 10.2 mm × 7.5 mm with 0.65 mm pin pitch, compared to roughly 35.6 mm × 7.6 mm for a DIP-28 outline. Switching from DIP to SSOP saves over 60% of linear board length, which is significant for space-constrained PCBs in handheld instruments and small appliance controllers.
