PIC16F1613-I/ST - 8-Bit MCU, 32MHz, 3.5KB Flash, XLP | Microchip
MPN: PIC16F1613-I/ST ✓ Hoạt độngPIC16F1613-I/ST Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (Flash), data memory (RAM), and peripherals on one die. Within the broader semiconductor taxonomy, an MCU is a subset of microcontrollers, which in turn belong to the embedded processor class of integrated circuits. PIC microcontrollers use a RISC architecture with a small, fixed instruction set optimized for deterministic real-time control in cost- and power-sensitive embedded designs. The "XLP" (eXtreme Low Power) designation indicates Microchip's family of nanoWatt technology parts with sub-uA sleep currents for battery-powered applications.
Key differentiating features include the integrated 24-bit SMT for high-resolution time-of-flight, angle, or duty-cycle measurement in motor and lighting control, and on-chip zero-cross detect for TRIAC-based AC dimming without external zero-cross circuitry. The peripheral pin select (PPS) mapper allows remapping of digital peripherals to multiple I/O pins, simplifying PCB layout. With eXtreme Low Power (XLP) technology, the device typically consumes <30 nA in sleep with brown-out reset enabled, making it well-suited for always-on, battery-backed, or energy-harvesting systems.
The PIC16F1613 uses an enhanced mid-range 8-bit RISC core with a hardware multiplier, 16-level stack, and a 49-instruction set optimized for C and assembly development under MPLAB X IDE with the XC8 compiler. In-circuit debugging is supported via the two-wire ICD interface, and in-circuit serial programming (ICSP) allows firmware updates after PCB assembly. The 10-bit ADC supports up to 8 channels with an internal fixed voltage reference and a sample-and-hold front end.
Typical applications include small brushed-DC and stepper motor control, LED lighting with TRIAC dimming, capacitive-touch user interfaces, sensor signal conditioning, general-purpose digital I/O expansion, and low-power IoT edge nodes. The TSSOP-14 footprint makes it attractive where PCB area is constrained and pin count beyond 8 is needed.
When designing with this part, plan current budget for active and sleep modes against battery capacity, place a 0.1 uF decoupling capacitor within 5 mm of VDD, and reserve one I/O pin as ICSPCLK/ICSPDAT for in-circuit serial programming. Note that the PIC16F1613 has 14 pins; if more I/O is required, the PIC16F1613 family also offers 8- and 16-pin variants on the same silicon, with code compatibility preserved.

Ứng dụng tiêu biểu
PIC16F1613-I/ST phù hợp cho 7 Áp dụngs: TRIAC AC Dimmer with Zero-Cross Detect, Small Brushed DC Motor Control, Capacitive Touch User Interface, Battery-Powered IoT Edge Sensor Node, LED Lighting Driver with Dimming, General-Purpose Digital I/O Expansion, Hobbyist and Educational Embedded Projects.
TRIAC AC Dimmer with Zero-Cross Detect
The PIC16F1613-I/ST is uniquely suited for TRIAC-based AC dimmers because its on-chip zero-cross detection eliminates the external optocoupler zero-cross circuit. The 24-bit SMT can measure the AC line angle to within nanoseconds for accurate phase-angle or forward/reverse phase-cut dimming. The XLP <30 nA sleep current enables always-listening wall switches drawing minimal standby power from capacitive droppers. Place a 0.1 uF decoupling capacitor within 5 mm of VDD.

Small Brushed DC Motor Control
The PIC16F1613-I/ST's integrated CCP module and 24-bit SMT make it well-suited for closed-loop brushed DC motor control. The 10-bit ADC reads back-EMF or current-sense feedback, while the CCP generates PWM at up to 32 MHz instruction rate. Peripheral Pin Select (PPS) lets the designer route PWM, fault, and brake signals to any I/O pin without board rework, reducing layout complexity in tight TSSOP-14 designs.
Được đề xuất
Capacitive Touch User Interface
With its low-power XLP technology, the PIC16F1613-I/ST is ideal for capacitive touch keypads on battery-powered remote controls and appliances. The integrated SMT supports capacitive touch scanning algorithms, while PPS allows reassignment of touch channels to multiple pins. Sleep current below 30 nA means a CR2032 coin cell can power the touch interface for years of standby operation.

Battery-Powered IoT Edge Sensor Node
The PIC16F1613-I/ST's <30 nA sleep current and 2.3V minimum supply make it an excellent edge-node MCU for IoT sensor applications, especially when paired with a low-power radio module over UART or SPI. Its 10-bit ADC can read analog sensors directly, and the XLP sleep retains RAM and limited peripherals for instant wake. Recommended for sub-1 GHz or BLE-connected thermostats, water meters, and remote controls.
Được đề xuất
LED Lighting Driver with Dimming
For constant-current LED drivers with analog or PWM dimming, the PIC16F1613-I/ST integrates the 10-bit ADC to read light-level sensors and the CCP module to generate PWM dimming at up to 32 MHz. The XLP sleep allows the LED driver to enter micro-watt standby when the lamp is off. Compatible with constant-current driver ICs such as the AL8860 via analog dimming input.
Được đề xuất
General-Purpose Digital I/O Expansion
In designs where a host processor lacks sufficient GPIO or PWM channels, the PIC16F1613-I/ST can serve as an I/O expander communicating via I2C or SPI. Its PPS mapper routes any peripheral to any I/O pin, simplifying PCB layout. The TSSOP-14 footprint is easy to hand-solder for prototypes, and the same PIC16 silicon runs the same firmware at 32 MHz for low-latency I/O.
Được đề xuất
Hobbyist and Educational Embedded Projects
The PIC16F1613-I/ST, paired with MPLAB X IDE and the XC8 compiler (free version), is a popular choice for hobbyists learning 8-bit embedded development. The TSSOP-14 footprint is easy to solder on breakout boards, and ICSP allows in-circuit programming without removing the chip. Project ideas include line-following robots, custom alarm clocks, and small appliances.

Ghi chú thiết kế
Place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin (pin 4) and a bulk capacitor (1-10 uF) on the same supply trace to handle inrush during MCU wake. The XLP <30 nA sleep current assumes BOR is enabled; if you disable BOR, idle current may rise. For battery-powered designs, use Sleep + WDT or Sleep + external interrupt wake to achieve the lowest average current.
The TSSOP-14 footprint is hand-solderable with a fine tip, but for production use proper SMT pads with a 1:1 footprint ratio. Keep the ICSP pins (RB6/ICSPCLK and RB7/ICSPDAT) accessible - either route them to a 2x3 or 1x6 header or expose test pads - so that MPLAB X with PICkit 4 can program/debug the board after assembly.
Do not tie MCLR (pin 3, RA5/MCLR/VPP) directly to VDD without a 10 kohm pull-up - the ICSP programmer needs to drive this pin low for reset. Configuration bits must be set in code (e.g., #pragma config) to enable or disable features like watchdog, BOR, and LVP; forgetting this is a common source of confusion. The Peripheral Pin Select (PPS) mapper must be unlocked (PPSLOCK = 0x55, 0xAA sequence) before reassigning peripheral functions.
The zero-cross detect input has a maximum input voltage spec - route the AC-derived signal through a current-limiting resistor and clamp network. For TRIAC dimming, use a snubber RC network across the TRIAC (typically 100 ohm + 0.01 uF) to limit dv/dt and prevent false triggering. The 24-bit SMT input pin can be sensitive to noise; place the SMT signal trace away from switching power lines and add a small RC filter if needed.
