- Dual 16-bit PWM outputs and integrated DAC channels for direct analog signal generation and precise motor or LED control
- 1.8 V minimum supply operation at 16 MHz in a compact 14-pin TSSOP package for ultra-low-power portable and IoT sensor designs
Applications
The PIC16F18124-I/ST is designed for battery-powered IoT sensor nodes, wearable devices, and compact control circuits where the 12-bit differential ADCC handles sensor data filtering in hardware to reduce CPU wake time and power consumption. Its dual 16-bit PWM outputs make it suitable for LED dimming, DC motor speed control, and switching power supply feedback loops. The 14-pin TSSOP form factor and 1.8 V operation enable integration into space-constrained smart home sensors and industrial transmitters.

Frequently Asked Questions
What makes the 12-bit differential ADCC in the PIC16F18124-I/ST different from a standard ADC in embedded applications?
The ADCC (ADC with Computation) in the PIC16F18124-I/ST adds hardware averaging, threshold comparison, and burst sampling modes that execute without CPU intervention. For example, the ADCC can accumulate 64 samples and compare the running average against a programmed threshold, waking the CPU only when the result crosses a limit. This reduces active CPU time and system power consumption significantly compared to a standard 12-bit ADC requiring software polling.
At what supply voltage and clock speed combination does the PIC16F18124-I/ST achieve lowest operating power?
The PIC16F18124-I/ST operates from a minimum supply of 1.8 V at up to 16 MHz, and achieves its lowest active current at 1.8 V with a reduced clock of 1 MHz or lower. In sleep mode the device draws below 100 nA, while active mode at 1 MHz and 1.8 V consumes approximately 30 µA, making it suitable for single-cell lithium or dual-AAA battery-powered sensors with multi-year life expectations.
How do the dual 16-bit PWM outputs of the PIC16F18124-I/ST benefit LED dimming or motor control designs?
The two independent 16-bit PWM modules provide a duty-cycle resolution of 1 part in 65536 at the configured PWM frequency, enabling flicker-free LED dimming across a brightness range of 0% to 100% with imperceptible steps even at low duty cycles below 1%. For brushed DC motor control, the dual PWM outputs can drive an H-bridge forward and reverse direction pins independently, achieving precise speed control from a single 8-bit PIC16 device without external PWM generators.
For a compact IoT sensor transmitter, why is the 14-pin TSSOP package of the PIC16F18124-I/ST preferable to a larger DIP variant?
The 14-pin TSSOP package has a body size of approximately 5 mm x 4.4 mm with a 0.65 mm pin pitch, occupying roughly 70% less PCB area than an equivalent 14-pin DIP package. This small footprint allows the PIC16F18124-I/ST to share a compact PCB with a wireless transceiver, antenna matching network, and battery connector within a total board area under 20 mm x 20 mm, which is a common constraint in coin-cell IoT nodes and wearable sensor patches.
