Applications
PIC18F2423-I/ML suits compact sensor-fusion nodes and small appliance controllers that need 10 analog inputs sampled at 12-bit resolution alongside UART or I2C communication, all within a 5 mm × 5 mm QFN-ML footprint. Its 2 V minimum supply enables direct operation from a single lithium coin cell or two-AA battery pack in handheld instrumentation and portable data loggers. Running at up to 40 MHz with 16 KB of Flash, it handles moderate PID control loops and communication protocol stacks without an external memory device.

Frequently Asked Questions
For a portable data logger sampling 8 analog sensors, how does PIC18F2423-I/ML handle simultaneous multi-channel acquisition at 12-bit resolution?
PIC18F2423-I/ML provides a 10-channel 12-bit ADC with a sample-and-hold circuit capable of up to 100 ksps throughput, allowing sequential scanning of all 8 channels and storing results in 768 bytes of on-chip RAM before transmitting over the built-in USART, without requiring an external ADC device.
When running PIC18F2423-I/ML at reduced clock speed from a 2 V lithium coin cell, what performance trade-offs should designers expect?
At 2 V supply, PIC18F2423-I/ML is specified to operate at up to 4 MHz clock frequency, reducing instruction throughput compared to the full 40 MHz rated speed at 5.5 V, but enabling the device to run directly from a CR2032 coin cell without a boost converter while keeping active current below 1 mA.
How does PIC18F2423-I/ML compare to PIC18F2520 for a cost-sensitive thermostat design with I2C temperature sensor and 7-segment display?
PIC18F2423-I/ML and PIC18F2520 share the same 28-pin QFN-ML footprint and peripheral set including I2C and MSSP, but PIC18F2423-I/ML offers a 12-bit ADC versus the 10-bit ADC in PIC18F2520, providing finer resolution for thermistor-based temperature sensing without increasing PCB size or BOM cost.
What is the Flash program memory capacity of PIC18F2423-I/ML, and does it support in-circuit serial programming for field firmware updates?
PIC18F2423-I/ML provides 16 KB of self-programmable Flash program memory and supports Microchip ICSP via a 2-wire interface using only the PGC and PGD pins, allowing field firmware updates through a standard PICkit programmer without removing the 28-pin QFN chip from the target board.
