PIC16LF18324-I/JQ - 8-bit 32MHz XLP MCU, 7KB Flash UQFN-16 | Microchip
MPN: PIC16LF18324-I/JQ ✓ Hoạt độngPIC16LF18324-I/JQ Tóm tắt
A microcontroller (MCU) is a single-chip computer integrating a CPU core, non-volatile program memory, working RAM, and a set of on-die peripherals. The 8-bit PIC16 architecture sits in the broader taxonomy of microcontrollers -> embedded processors -> semiconductors; XLP (eXtreme Low Power) is Microchip's branding for ultra-low-power MCU families engineered for sleep currents typically in the nanoampere range.
Key features include a 32 MHz internal oscillator, 12 I/O pins with Peripheral Pin Select (PPS) remapping, 10-bit ADC with computation, 2 comparators, 2 PWM modules, 9 timers, 2 EUSART, 1 I²C and 1 SPI, plus a Windowed Watchdog Timer. Operating voltage spans 1.8 V to 3.6 V, suiting battery and energy-harvesting systems.
Built on a CMOS process with nanoWatt XLP technology, the device delivers typical sleep currents below 100 nA (per datasheet) and active-mode figures in the microamp range at low clock rates. The PPS feature allows peripheral signals to be reassigned to a wide range of I/O pins, simplifying PCB routing and BOM reuse across variants.
Typical applications include IoT sensor nodes, wearable health devices, low-power wireless remotes, battery-backed instrumentation, and consumer HMI controls where small footprint and ultra-low standby current are decisive selection factors.

Ứng dụng tiêu biểu
PIC16LF18324-I/JQ phù hợp cho 6 Áp dụngs: IoT Wireless Sensor Node, Wearable Health Monitor, Battery-Backed Instrumentation, Low-Power Wireless Remote Control, Consumer HMI Control, Automotive Body Electronics (Sub-System).
IoT Wireless Sensor Node
The PIC16LF18324-I/JQ fits battery-powered IoT sensor nodes thanks to its nanoWatt XLP sleep current below 100 nA (per Microchip XLP family data) and 32 MHz active performance. Its 10-bit ADC² with averaging and oversampling reduces firmware filtering load for analog sensors like temperature, humidity, or gas detectors. The 12 GPIO pins via Peripheral Pin Select let designers route SPI to a sub-GHz radio and I²C to a sensor without PCB rework. At 7 KB Flash and 256 B EEPROM the part supports BLE/Zigbee-ready stacks plus persistent configuration storage across battery swap events.

Wearable Health Monitor
Wearables demand coin-cell operation and small footprint, both delivered by the PIC16LF18324-I/JQ. The 1.8 V to 3.6 V operating range supports direct connection to a CR2032 cell with no boost converter. The 16-UQFN 4 × 4 mm package fits wristband PCBs, while 9 timers provide fine-grained PWM for haptic feedback and EUSART for BLE module handshaking. XLP sleep currents below 100 nA extend battery life into multi-month territory for always-on wearables. Designers can use ADC² to oversample heart-rate or SpO2 photodiode signals, reducing external analog components.

Battery-Backed Instrumentation
Industrial and medical instruments that retain settings during power loss benefit from the PIC16LF18324-I/JQ's 256 B EEPROM. The 10-bit ADC² provides calibrated voltage, current, and temperature sensing with hardware averaging, simplifying firmware. PPS allows flexible routing of UART debug lines away from analog inputs to reduce crosstalk. Operating temperature from -40 °C to +85 °C suits factory-floor and outdoor enclosures. Designers typically pair this MCU with a serial EEPROM or FRAM if non-volatile log storage exceeds 256 B, but the on-chip EEPROM covers most user-calibration and unit-ID storage needs.

Low-Power Wireless Remote Control
Remote controls are duty-cycled devices that spend 99% of their life in deep sleep, making the PIC16LF18324-I/JQ ideal. The internal 32 MHz HFINTOSC eliminates a crystal, reducing BOM cost for handheld transmitters. Two PWM channels can drive IR LEDs with carrier modulation, while the comparator triggers wake-up on capacitive-touch events via the dedicated touch hardware. With nanoWatt XLP sleep currents below 100 nA, an alkaline-powered remote can run years on a single pair of AAA cells. The 12 I/O pins are ample for keypads up to 4 × 4 via charlieplexing.

Consumer HMI Control
Small home appliances and consumer devices with segment-LCD or LED-7-segment HMIs leverage the PIC16LF18324-I/JQ's PWM, EUSART, and ADC² resources. The 32 MHz CPU executes lighting patterns and motor-control loops with deterministic timing, and PPS reassigns SPI to either an EEPROM or a display driver without board respins. Operating voltage down to 1.8 V supports direct lithium-ion battery monitoring. The 256 B EEPROM stores user preferences across power cycles, while the 10-bit ADC reads potentiometers, photodiodes, or thermistors with hardware averaging for stable readings.

Automotive Body Electronics (Sub-System)
Body-electronics sub-modules that don't require full automotive grade can use the PIC16LF18324-I/JQ on 12 V rails stepped down to 3.3 V. The 32 MHz performance handles LIN slave stacks and LED matrix animations. With 9 timers, multiple PWM channels drive LED drivers and motor pre-drivers without external timer ICs. PPS simplifies routing between UART, SPI, and PWM outputs, reducing PCB layer count. For modules that do require AEC-Q100, designers migrate to PIC16F18324-E/JQ (extended temp) on the same footprint. Operating temperature -40 °C to +85 °C covers cabin and most under-bonnet sub-modules when derated.

Ghi chú thiết kế
Estimated: at VDD = 3.3 V and CPU = 32 MHz (active), the typical active current is approximately 3 mA per Microchip XLP family datasheet characteristics; at deep sleep it falls below 100 nA. Designers targeting multi-year coin-cell life must minimize active-mode duty cycle, gate unused peripherals with PMD bits, and select the lowest LFINTOSC frequency that meets response-time requirements. Always place a 0.1 µF ceramic bypass capacitor within 5 mm of the VDD pin and a 10 µF bulk capacitor at the regulator output to suppress voltage spikes during transmit bursts.
The 16-UQFN (4 × 4 mm) package has an exposed thermal pad that MUST be soldered to a 1 × 1 mm (minimum) copper island on the top layer, stitched with at least 4 thermal vias (0.3 mm drill) to the bottom ground plane. Without proper pad soldering, mechanical reliability under thermal cycling is significantly reduced, and ground-bond inductance degrades ADC accuracy. Keep digital traces away from analog ADC inputs by at least 2 mm or guard them with a ground trace to reduce capacitive coupling.
Use the PPS feature to assign high-frequency peripherals (SPI, EUSART clocks) to adjacent pin pairs to shorten trace lengths. Place the 32.768 kHz crystal (if used) within 5 mm of the SOSCO/SOSCI pins and guard it with a grounded ring. The MCLR pin requires a 10 kΩ pull-up to VDD and a 100 nF capacitor to ground for in-circuit serial programming (ICSP); routing these too far can cause programming failures in production.
Do not exceed VDD = 3.6 V absolute maximum or the on-chip EEPROM endurance specification (typically 100k write cycles per byte) may degrade. Do not enable ADC² without first enabling the FVR (Fixed Voltage Reference) module or the ADC reference will float. Avoid driving high-current loads (>10 mA) directly from GPIO pins; use a MOSFET driver or buffer. PPS lock bits must be cleared before reprogramming peripherals, otherwise PPS remapping silently fails.
