Frequently Asked Questions
At what minimum supply voltage can the PIC18F24K20-E/SP operate, and how does clock speed change with supply?
The PIC18F24K20-E/SP operates at a minimum supply of 1.8 V for a clock speed of up to 16 MHz, and at 2.0 V it supports up to 20 MHz. Full 48 MHz operation requires a higher supply voltage. This voltage-frequency scaling allows the device to optimize power consumption in battery-constrained or energy-harvesting designs.
What extended temperature range does the PIC18F24K20-E/SP support, and which industrial environments benefit from this rating?
The PIC18F24K20-E/SP carries an extended temperature rating of -40°C to +125°C. This qualifies it for automotive underhood sensing, industrial outdoor enclosures, HVAC systems, and oil-field monitoring equipment where ambient temperatures can exceed the standard commercial range of 0°C to +70°C.
How many I/O pins does the PIC18F24K20-E/SP provide, and is there on-chip EEPROM for persistent data storage?
The PIC18F24K20-E/SP provides 25 I/O pins and includes 256 bytes of on-chip EEPROM in addition to its 16 KB Flash and 768 bytes of RAM. The EEPROM allows storing calibration values, device addresses, or configuration parameters that must survive power interruptions without requiring external non-volatile memory.
When should a designer choose PIC18F24K20-E/SP over the lower-end PIC16F series for the same application?
PIC18F24K20-E/SP is preferred over PIC16F devices when the application requires more than 14 KB of Flash, a higher maximum clock of 48 MHz, richer interrupt handling with hardware interrupt priority levels, or the extended -40°C to +125°C temperature range. For simpler applications with smaller code footprint and lower cost targets, a PIC16F part may be more cost-effective.
