PIC16F1613-E/ML Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash, RAM, EEPROM), and programmable I/O peripherals onto one silicon die. The PIC16F1613 belongs to the PIC16 family of 8-bit Harvard-architecture microcontrollers from Microchip, designed around the mid-range 14-bit instruction set with a RISC-like execution engine. Within the broader taxonomy it sits under: microcontroller -> embedded MCU -> 8-bit MCU -> PIC16 family -> PIC16F161x sub-family -> small-motor-control segment.
Key features include 3.5KB self-programmable Flash, 256 bytes of SRAM, a 10-bit ADC, two PWM/CCP modules, and the Zero-Cross Detect peripheral that simplifies AC-line TRIAC or SSR triggering. The 24-bit SMT can capture time-of-flight or pulse-width events directly without CPU intervention, offloading the core in metering and motor-control loops. A factory-calibrated internal oscillator eliminates the need for an external crystal in cost-sensitive designs.
Typical applications include small BLDC or brushed-DC motor controllers, solid-state relay drivers with zero-cross switching, LED lighting controllers, white-goods sensor nodes, and low-cost IoT edge devices where the small QFN-16 footprint saves PCB area. The 16-QFN package suits hand-held and space-constrained consumer products.
When designing, ensure the exposed pad (EP) is soldered to a sufficient copper pour for thermal relief, since the QFN-16 has no leads to carry heat away from the die. Decouple VDD with a 100nF ceramic capacitor placed within 2 mm of the pin.

Typical Applications
PIC16F1613-E/ML is suitable for 6 applications: Small BLDC Motor Control, AC-Line Solid-State Relay and TRIAC Driver, LED Lighting Controllers, White-Goods Sensor Nodes, Cost-Sensitive IoT Edge Devices, Ultrasonic Time-of-Flight Measurement.
Small BLDC Motor Control
The PIC16F1613-E/ML's two CCP/PWM modules plus its 24-bit Signal Measurement Timer make it a strong fit for small brushless DC motor controllers in fans, pumps, and appliance drives. The PWM can generate complementary 6-step commutation at up to 10-bit resolution, while the SMT captures back-EMF zero-cross events to time the next commutation without CPU intervention. The integrated Zero-Cross Detect peripheral simplifies block-commutation of brushed AC motors and supports sensorless trapezoidal commutation at moderate speeds.
Recommended
AC-Line Solid-State Relay and TRIAC Driver
For AC-line switching of resistive or inductive loads, the PIC16F1613-E/ML's Zero-Cross Detect peripheral generates an interrupt at every mains zero crossing, allowing the firmware to schedule precise TRIAC firing angles and reduce EMI and inrush current. Combined with the 10-bit ADC for current sensing and the 24-bit SMT for timing the firing pulse width, the MCU can implement proportional AC power control in dimmers, heater regulators, and SSR replacements with no external zero-cross optocoupler.
Recommended
LED Lighting Controllers
The PIC16F1613-E/ML's two CCP/PWM channels can drive LED strings with smooth dimming via analog or PWM control, while the ADC2 with Computation block supports color-mixing algorithms for RGB or tunable-white fixtures. The Zero-Cross Detect peripheral enables phase-angle dimming of AC mains LEDs and AC-LED retrofit lamps without an external zero-cross optocoupler, reducing BOM cost. The wide 2.3V to 5.5V supply range simplifies power-supply design across both 3.3V and 5V LED-driver topologies.
Recommended
White-Goods Sensor Nodes
In washing machines, dishwashers, and refrigerators, the PIC16F1613-E/ML serves as a sensor-conditioning MCU that reads NTC thermistors, water-level probes, and door switches via its 10-bit ADC2 and routes data to a main controller over UART or I2C. The 24-bit SMT captures flow-meter pulses with sub-microsecond resolution, enabling accurate water- and energy-metering inside the appliance. The extended -40C to +125C temperature grade supports the harsh thermal environment of an appliance cabinet.
Recommended
Cost-Sensitive IoT Edge Devices
The PIC16F1613-E/ML's combination of 3.5KB Flash, 256B SRAM, integrated 32 MHz internal oscillator, and 16-QFN footprint makes it a cost-optimized host for IoT end-nodes that aggregate a few sensors and drive a relay or PWM output. The MCU can sleep at sub-microamp currents while the ADC2 monitors analog thresholds, waking only on threshold-cross events to transmit over UART. Its small QFN-16 footprint suits coin-cell powered sensors and wearable beacons.
Recommended
Ultrasonic Time-of-Flight Measurement
The PIC16F1613-E/ML's 24-bit Signal Measurement Timer can directly capture ultrasonic echo pulses with 24-bit resolution, enabling accurate distance measurement in parking sensors, tank-level meters, and robotic ranging. The SMT offloads the timing-critical edge-capture work from the CPU, freeing cycles for filtering or serial output. The integrated Zero-Cross Detect peripheral can be repurposed to detect zero-crossings of the 40 kHz burst waveform, simplifying analog front-end design.

Key Differentiators
- Integrated Zero-Cross Detect peripheral (vs PIC16F1825-I/ML)
- 24-bit Signal Measurement Timer (vs PIC16F1516-I/ML)
- Extended -40C to +125C temperature grade (vs PIC16F1613-I/ML)
Design Notes
The 16-QFN (ML) package has a thermal pad on the underside that MUST be soldered to a copper pour to dissipate die heat and provide substrate grounding. Without the EP soldered, the junction-to-ambient thermal resistance increases significantly, potentially triggering thermal shutdown during sustained ADC and PWM activity. Microchip recommends at least 25 mm^2 of 1 oz copper connected to the EP for typical applications.
Place the VDD decoupling capacitor (100 nF X7R) within 2 mm of the VDD pin (pin 12) and a bulk 10 uF tantalum or ceramic on the same node. For battery-backed designs, add a 100 kohm pull-up on MCLR/RA3 (pin 4) to VDD to ensure a clean reset; otherwise an RC delay may be needed. Keep the analog traces (AN0-AN4, AN10-AN11) short and away from PWM outputs to avoid digital-to-analog crosstalk into the ADC.
Do not confuse the 'F' (Flash) device with 'LF' (low-power Flash) variants: the LF parts operate at lower VDD min and have reduced performance. The 'E' suffix means -40C to +125C extended; 'I' is -40C to +85C industrial. Designers migrating from PIC16F1825-I/ML must check the Zero-Cross Detect and 24-bit SMT peripheral availability since they are unique to the PIC16F161x family and absent on PIC16F1825.
Compliance Information
