PIC16F18424-E/P - 8-bit XLP MCU, 7KB Flash, 14-PDIP | Microchip
MPN: PIC16F18424-E/P ✓ Hoạt độngPIC16F18424-E/P Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path. In the broader system hierarchy it sits under microcontroller -> embedded controller -> semiconductor device. The PIC16 family uses a RISC instruction set with a 14-bit program word and a small, deterministic instruction set optimized for compact code, fast context switching, and ultra-low-power operation. Microcontrollers like the PIC16F18424 are typically placed in the system alongside power management ICs, sensors, and discrete semiconductors on a mixed-signal board.
Key features include a 12-bit ADC with Computation (ADCC), a 5-bit DAC, two PWMs, an on-chip comparator, a Complementary Waveform Generator (CWG), and the EUSART plus SPI/I2C serial engines. Functional Safety (FuSa) capability supports IEC 61508 SIL 2/3 system designs. The device supports 1.8V to 5.5V VDD operation, with typical sleep currents measured in the nanoampere range thanks to XLP technology.
Typical applications include IoT sensor nodes, low-power wireless HMI controllers, battery-powered instrumentation, automotive body and sensor modules, and consumer white-goods user interfaces. The 14-pin PDIP package is favored for hobbyist and breadboard-friendly designs as well as through-hole industrial modules where mechanical robustness matters more than board density.
When designing with this device, ensure your programmer/debugger supports the PIC16F18424 die (MPLAB X IDE with XC8 compiler and a PICkit 4 or Snap debugger are typical). If the design is pin-constrained, consider the same family in 8-pin SOIC/DFN; if the design needs higher pin count, look to the 20-pin PIC16F18446 in the same family.

Ứng dụng tiêu biểu
PIC16F18424-E/P phù hợp cho 6 Áp dụngs: IoT Sensor Node Controller, Battery-Powered Instrumentation, Automotive Body Electronics, Consumer White-Goods User Interface, Low-Power Wireless HMI Controller, Educational and Hobbyist Development.
IoT Sensor Node Controller
The PIC16F18424-E/P is well-matched to IoT sensor nodes because its eXtreme Low-Power (XLP) sleep current is in the nanoampere range while the 32 MHz active clock and 12-bit ADCC with computation support rapid wake-and-sample cycles. Power budget math: with a 10-second sleep interval and 5 ms active window at 3 V VDD, the average current draw is dominated by sleep, easily enabling 1+ year life on a CR2032 coin cell. Placed as the central MCU on the sensor board with EUSART or SPI/I2C connecting to a wireless module, the device provides deterministic core-independent peripheral (CIP) behavior without CPU wake-up.

Battery-Powered Instrumentation
Portable instruments such as digital thermometers, hand-held multimeters, and field data loggers benefit from the PIC16F18424-E/P's combination of 12-bit ADCC with computation (enabling on-chip oversampling for 14+ bit effective resolution) and the 5-bit DAC for stimulus or bias generation. At 32 MHz the device completes 12-bit ADC conversions and averaging in under 50 µs, allowing high channel-scan rates. XLP nano-sleep current keeps idle idle current to a minimum, preserving battery life between measurement cycles.

Automotive Body Electronics
The PIC16F18424-E/P's -40 °C to +125 °C extended temperature range and FuSa capability make it suitable for automotive body modules such as mirror controllers, ambient lighting drivers, and seat-position sensors. The 12-bit ADCC handles ratiometric sensor readings (NTC thermistors, Hall sensors), while the CWG (Complementary Waveform Generator) plus two PWMs drive LED strings or small brushed-motor loads without CPU intervention. According to Microchip automotive documentation, this part supports designers targeting IEC 61508 SIL 2/3 functional safety systems.

Consumer White-Goods User Interface
Washing machines, dishwashers, and ovens commonly use the PIC16F18424-E/P for HMI logic: scanning key matrices, driving segmented LED or LCD displays, and coordinating with a host inverter MCU. The CWG can generate complementary PWM signals for small synchronous-rectification drive, the comparator supports zero-cross detection for AC line monitoring, and the EUSART links to the main control board. EEPROM storage retains user settings through power cycles; 12 bytes is sufficient for a basic user-mode/setting indicator.
Được đề xuất
Low-Power Wireless HMI Controller
The PIC16F18424-E/P pairs with sub-GHz or BLE modules as a low-power HMI host for smart-home wall switches, dimmers, and battery-free (energy-harvesting) remote controls. Sleep current in the nanoampere range plus CIP-driven wake-on-touch via the on-chip comparator lets the device draw almost no power when idle, waking only on user input. SPI/I2C drives the wireless transceiver and the 5-bit DAC can synthesize audio feedback tones for user confirmation.
Được đề xuất
Educational and Hobbyist Development
The PIC16F18424-E/P's 14-pin PDIP form factor is breadboard-friendly and supported by Microchip's MPLAB X IDE with the XC8 compiler plus PICkit 4 or Snap debugger, making it a strong teaching platform for embedded systems courses. Students can exercise ADC sampling, PWM generation, I2C/SPI peripheral communication, and EEPROM data logging on a single chip. The FuSa documentation exposes learners to functional safety concepts in a hobbyist-accessible device.

Ghi chú thiết kế
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 8 (VDD) and a bulk 1 µF to 10 µF capacitor on the same supply rail. For battery-powered designs, leverage the XLP sleep modes (DOZE, SLEEP, IDLE) - the PIC16F18424-E/P typical sleep current is in the nanoampere range per the Microchip datasheet. Estimated: at 3 V VDD and 1 µA average current, a CR2032 coin cell (~220 mAh) yields 220,000 hours of theoretical life; subtract 80% derating for self-discharge and you still achieve years of operation.
Route the ICSP clock/data lines (RB6/RB7) away from high-current switching traces to avoid programming glitches. Place the ICSP connector footprint so a PICkit 4 or Snap debugger can be attached without removing the MCU. Keep analog inputs (RA0-RA2) traces short and surrounded by a ground pour to minimize ADC noise pickup; ADCC performance degrades when analog traces share routing with PWM outputs on RB4/RB5.
Do not exceed 5.5 V on VDD - the PIC16F18424-E/P is a 1.8 V to 5.5 V part, and over-voltage permanently destroys the device. Configure MCLR (pin 3) with a 10 kΩ pull-up to VDD if not driven externally; leaving MCLR floating can cause spurious resets. When migrating from the older PIC16F1825, verify that the 12-bit ADCC register map matches your firmware - although the family shares the peripheral concept, register names and initialization sequences differ.
For I2C bus pull-ups, choose values between 1 kΩ (fast-mode 400 kHz, short bus) and 10 kΩ (standard-mode 100 kHz, longer bus). The PIC16F18424-E/P I2C pins are open-drain and require external pull-ups. For SPI at 8 MHz or above, keep clock trace lengths under 50 mm and add a 33 Ω series resistor near the master pin to dampen reflections. Estimated: SPI trace length tolerance is approximately 1 ns/m; at 8 MHz (125 ns period) you can tolerate up to 125 mm of unterminated trace before risking signal integrity issues.
