PIC16F18424-E/JQ - 8-Bit XLP MCU 7KB Flash 16-UQFN | Microchip
MPN: PIC16F18424-E/JQ ✓ Hoạt độngPIC16F18424-E/JQ Tóm tắt
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (typically Flash), working RAM, and a rich set of peripherals such as timers, ADCs, communication interfaces, and GPIO. PIC microcontrollers use a RISC architecture optimized for deterministic instruction execution and very low power consumption. The PIC16F18424 belongs to the enhanced mid-range 8-bit core family and adds CIPs that offload tasks like waveform generation, signal conditioning, and complementary output control without CPU intervention. Positioned in the hierarchy MCU -> microcontroller -> embedded controller -> semiconductor, this device targets battery-powered and space-constrained designs.
Key specifications include a 12-bit ADC with Computation (ADCC), a 5-bit DAC, two PWMs, a Complementary Waveform Generator (CWG), an EUSART plus SPI/I2C peripherals, and Functional Safety (FuSa) support for safety-critical applications. The integrated Peripheral Pin Select (PPS) allows flexible remapping of digital peripherals to any I/O pin, simplifying PCB layout in small 16-pin packages.
The 16-UQFN package measures just 4x4 mm, suiting wearables, sensor nodes, and handheld instruments. The XLP Sleep mode draws under 50 nA typical, and the device offers multiple low-power operating modes such as Doze, Idle, and Sleep with peripheral operation using the LFINTOSC or the 16 MHz HFINTOSC.
Typical applications include IoT sensor nodes, battery-powered environmental monitors, LED lighting controllers, automotive body electronics, home appliance user interfaces, and low-power industrial sensor transmitters. Functional Safety support makes it a fit for auxiliary safety subsystems.
When designing, place a 0.1 µF decoupling capacitor close to VDD and ensure the ICSP™/ICD pins are accessible for in-circuit programming and debug. Use PPS to route peripherals to convenient pins, and select the appropriate oscillator mode to balance wake-up time against quiescent current.

Ghi chú thiết kế
Place a 0.1 µF decoupling capacitor as close as possible to the VDD pin (pin 16) with a trace length under 5 mm. Add a bulk 1-10 µF capacitor near the regulator output. In battery designs, use XLP Sleep mode with HFINTOSC disabled; wake via Watchdog Timer or IOC to minimize Sleep current. Estimated Sleep current based on PIC16F184xx family typical specifications is under 50 nA with RTC running.
The 16-UQFN (4x4 mm) has an exposed thermal pad that should be soldered to a copper pad tied to VSS for mechanical strength and thermal dissipation. Route ICSPCLK and ICSPDAT (RA0/RA1) to a 2x3 0.1 inch header or pogo-pad footprint for in-circuit programming and debug. Use PPS to assign peripherals to convenient pins and keep high-speed traces short.
Do not confuse PIC16F18424 with PIC16LF18424: the F variant operates 2.5 V to 5.5 V, while the LF variant is 1.8 V to 3.6 V. MCLR on RA3 is enabled by default in configuration bits; if used as GPIO, disable MCLR via CONFIG3. PPS must be unlocked before remapping; failing to do so produces silent peripheral failures. Always verify configuration bits in MPLAB X before programming production parts.
