- 7 KB Flash and 512 B RAM with 128 B EEPROM for standalone embedded firmware storage
- 12-bit differential ADCC with computation hardware for direct signal conditioning without software overhead
- Dual 16-bit PWM outputs enabling precise motor control and LED dimming at up to 32 MHz clock
- Low-voltage operation from 1.8 V at 16 MHz extending compatibility with single-cell battery systems
- 14-pin SOIC-14 package balancing I/O availability and compact PCB footprint for space-constrained designs
What is PIC16F18124-I/SL used for?
The PIC16F18124-I/SL is suited for battery-operated sensor nodes, smart switches, and small appliance controllers where an 8-bit MCU with analog front-end and PWM outputs must fit in a 14-pin SOIC footprint. Its 12-bit differential ADCC enables direct interfacing to bridge sensors, thermistors, and current-sense shunts without external amplifiers, reducing BOM cost. The dual 16-bit PWM channels make it effective for DC motor speed control, servo positioning, and RGB LED brightness management in consumer and industrial embedded designs.

Frequently Asked Questions
What is the maximum clock frequency of the PIC16F18124-I/SL, and at what supply voltage can it run at full speed?
The PIC16F18124-I/SL runs at up to 32 MHz clock frequency, achievable at supply voltages of 2.3 V and above. At a reduced 1.8 V supply, the maximum frequency is 16 MHz, which still provides sufficient processing throughput for most sensor acquisition and control tasks in low-power battery-operated designs.
How does the 12-bit differential ADCC in the PIC16F18124-I/SL simplify sensor signal conditioning compared to a basic successive-approximation ADC?
The differential ADCC measures the voltage difference between two input pins with 12-bit resolution, rejecting common-mode noise that affects both inputs equally. Built-in computation hardware can accumulate and average multiple ADC samples automatically, reducing the software overhead to a single read of a filtered result register instead of implementing a running average in firmware. This is particularly valuable when reading bridge-type sensors or current-sense resistors in noisy industrial environments.
For a 2-channel DC motor controller on a single PIC16F18124-I/SL, are the 2 PWM outputs and 14 pins sufficient for direction control, current sensing, and UART debug simultaneously?
Yes, the PIC16F18124-I/SL's 14 pins in the SOIC-14 package can accommodate 2 PWM outputs for motor speed, 2 direction control GPIO outputs, 1 analog input for current sensing via the 12-bit ADCC, and 2 UART pins for debug, leaving several additional I/O pins free. With 7 KB Flash, sufficient firmware space exists to implement the full motor control loop, ADC averaging, and UART logging simultaneously within the 8-bit PIC16 architecture.
