PIC16F18877-I/PT - 56KB Flash 8-bit MCU, 44-TQFP | Microchip
MPN: PIC16F18877-I/PT ✓ פעילPIC16F18877-I/PT סקירה
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash/ROM), data memory (RAM/EEPROM), and integrated peripherals such as ADC, timers, communication interfaces, and I/O ports. The PIC16F18877 belongs to the Microchip 8-bit PIC16 family, sits above the PIC10/PIC12/PIC14 entry-level series, and below the 16-bit dsPIC/PIC24 and 32-bit PIC32 families in the broader PIC microcontroller taxonomy.
Key features include 56 KB (32K x 14) self-programmable Flash, 4 KB SRAM, 256 bytes EEPROM, a 10-bit ADC with up to 43 channels, two comparators, two DACs, four 8/16-bit timers, two CCP modules, two 16-bit PWM modules, EUSART, two SPI/I2C interfaces, and a 32 MHz internal oscillator. Functional safety features include CRC/SCAN, HLT (Hardware Limit Timer), windowed watchdog, and memory scan support.
The architecture uses a 14-bit instruction word with an enhanced mid-range core, nanoWatt XLP technology for sleep currents below 50 nA typical, and idle/doze modes. The device operates from 1.8V to 5.5V (F version) and includes peripheral pin select (PPS) for flexible signal routing.
Typical applications include IoT sensor nodes, wearable devices, home appliances, low-power wireless HMI, functional safety consumer products, and general-purpose embedded control. The combination of low power, large memory, rich analog, and CIPs makes it well suited for battery powered designs.
Design consideration: The 44-TQFP footprint is suitable for hand soldering with appropriate pitch and a fine-tip iron, but production assembly should use reflow profiles per J-STD-020. Decoupling: place 100 nF near each VDD pin and a bulk 10 uF near the regulator output.

יישומים טיפוסיים
PIC16F18877-I/PT מתאים עבור 6 יישוםs: Battery-Powered IoT Sensor Node, Functional-Safety Household Appliance, Wearable Fitness/Health Tracker, Industrial Sensor Transmitter (4-20 mA), Smart Home HMI and Touch Control, Automotive Body and Comfort Module.
Battery-Powered IoT Sensor Node
The PIC16F18877-I/PT is well suited for battery-powered IoT sensor nodes due to its nanoWatt XLP technology, which delivers typical sleep currents below 50 nA with retention RAM intact. The 56 KB Flash supports over-the-air firmware update payloads and complex sensor fusion algorithms, while the 10-bit ADC with up to 43 channels allows direct interface to multiple analog sensors (temperature, humidity, gas) without an external mux. The integrated EUSART and dual SPI/I2C interfaces provide flexible connectivity to LoRa, sub-GHz transceivers, or BLE modules. At 32 MHz operation, the device can execute sensor reads and local processing at sub-mA active currents, extending coin-cell battery life to multiple years in duty-cycled designs.
מומלץ
Functional-Safety Household Appliance
The PIC16F18877-I/PT integrates functional safety features (CRC/SCAN, hardware limit timer HLT, windowed watchdog) that simplify IEC 60730 Class B compliance for household appliances like washing machines, dishwashers, and microwave ovens. The 56 KB Flash supports the safety library and self-test routines, while the dual comparators enable redundant protection for motor overcurrent and overtemperature. Its 1.8-5.5 V operation matches the typical 5 V and 3.3 V rails in appliance designs. The 44-TQFP package is compatible with both hand-soldered prototyping and high-volume reflow assembly on industry-standard 1.6 mm or 2-layer FR-4 PCBs.
מומלץ
Wearable Fitness/Health Tracker
The PIC16F18877-I/PT fits wearable fitness and health trackers because of its XLP sleep modes, integrated 10-bit ADC for biometric sensor reads (heart rate, SpO2 via analog front end), and small 44-TQFP footprint compatible with compact rigid-flex PCB designs. The peripheral pin select (PPS) routes EUSART, SPI, and I2C to any GPIO, simplifying PCB layout under tight space constraints. With 4 KB SRAM it can buffer sensor data between BLE transmissions, while the 2 CCP and 2 PWM modules drive vibration motors and LED indicators for user feedback. The industrial -40 C to +85 C temperature range supports outdoor and active-user scenarios.
מומלץ
Industrial Sensor Transmitter (4-20 mA)
The PIC16F18877-I/PT drives industrial 4-20 mA current-loop sensor transmitters by combining its 10-bit ADC for bridge-sensor linearization with its PWM output and op-amp loop to set the loop current. Its industrial -40 C to +85 C temperature range and 1.8-5.5 V operation support 24 V loop-powered designs after regulation. The 56 KB Flash enables on-device calibration tables, linearization math, and HART or IO-Link communication stacks via the EUSART. Functional safety features (CRC/SCAN, windowed WDT) improve reliability in process control environments where silent failures are unacceptable.
מומלץ
Smart Home HMI and Touch Control
The PIC16F18877-I/PT powers smart-home human-machine interfaces (HMIs) such as touch keypads, dimmers, and fan controllers. Its 10-bit ADC with up to 43 channels multiplexes multiple capacitive or resistive touch pads via external charge-sharing circuitry. The dual PWM outputs drive TRIACs or FETs for AC phase-angle or DC motor speed control. With 56 KB Flash the device can run Microchip's mTouch libraries, a Z-Wave or Bluetooth Low Energy host stack, and a full state machine for UI feedback. The 32 MHz CPU executes complex touch algorithms and UI updates within sub-1 ms frames.
מומלץ
Automotive Body and Comfort Module
The PIC16F18877-I/PT -VAO suffix variant supports automotive body and comfort applications such as interior lighting, seat controllers, mirror adjusters, and HVAC blend-door actuators. Its 32 MHz performance handles LIN-bus communication, PWM-driven LED drivers, and motor control loops in real time. Functional safety features and the wide 1.8-5.5 V supply range (compatible with automotive 12 V systems after regulation) suit AEC-Q100 Grade 3 environments. The 44-TQFP package supports high-density PCB designs and high-volume reflow assembly. For mission-critical powertrain applications, choose dsPIC33 or PIC18 derivatives with higher temperature grades.

הערות תכנון
Estimated: When using sleep mode with watchdog disabled and retention RAM enabled, typical current consumption is below 50 nA at 3.3 V. For accurate figures, refer to the datasheet DC characteristic table across the full -40 C to +85 C temperature range. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin and a 10 uF bulk capacitor near the regulator. Use a low-Iq LDO such as MCP1700 (1.6 uA quiescent) for battery applications to preserve the XLP benefit.
The 44-TQFP package has a 0.8 mm pitch - use IPC-7351 land patterns with NSMD pads for best reflow yield. Place ICSP/ICD pins (PGED/PGEC) at the edge of the PCB with accessible test points to allow in-circuit debugging without removing the MCU. Keep analog traces short and away from switching nodes (PWM outputs) to minimize ADC coupling; consider a ground guard ring around sensitive analog inputs.
Do not assume pin compatibility between -PT (TQFP) and -P (PDIP) packages - they have different pin counts (44 vs 40) and different pin assignments. Verify your firmware fits within 56 KB Flash and 4 KB SRAM before committing to a production BOM. The configuration words must be set correctly to enable the internal oscillator and disable unused peripherals to achieve low sleep current; leaving default brown-out settings may cause unwanted resets in noisy environments.
