PIC16F15324-E/7NVAO Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data memory, and peripherals on a single die. The PIC16F family belongs to the mid-range PIC architecture hierarchy: 8-bit MCU -> enhanced mid-range core -> PIC16F1xxx family -> 16-pin sub-family. PIC microcontrollers are widely used in automotive body electronics, white goods, sensor nodes, and consumer devices because they offer deterministic instruction execution, low active and sleep currents, and a long-life Flash program memory that supports frequent firmware updates in the field.
The part integrates 4x 10-bit PWMs with complementary waveforms, a 5-bit DAC, a comparator, a 10-bit ADC with computation, the Configurable Logic Cell (CLC), the Complementary Waveform Generator (CWG), and two Enhanced USART modules that also support SPI/I2C and LIN master mode. The Peripheral Pin Select (PPS) feature allows digital peripheral I/O to be remapped to most device pins, which simplifies PCB routing when multiple communication interfaces must coexist on a 16-pin package. The /NVAO suffix designates this variant as automotive-grade AEC-Q100 qualified and supplied on tape-and-reel in a VQFN package.
Typical applications include automotive body controllers, LIN nodes for sensor and actuator interfacing, low-power IoT sensor endpoints, white-goods user-interface boards, and battery-powered consumer devices. The 16-VQFN (4x4 mm) footprint suits space-constrained modules, while PPS, CIPs, and XLP enable the device to remain in sleep mode for extended periods while still responding to asynchronous events without CPU wake-up overhead.
When designing with this part, place a 0.1 uF decoupling capacitor within 2 mm of the VDD pin and bond the exposed pad to a contiguous ground copper pour for thermal dissipation and signal integrity. Programming is supported by Microchip's MPLAB X IDE and the PICkit or Snap in-circuit programmers; the device can also self-program via bootloader code stored in Flash. AEC-Q100 qualification makes the /VAO variant suitable for under-hood and cabin automotive electronics with operating temperatures from -40C to +125C.

Typical Applications
PIC16F15324-E/7NVAO is suitable for 6 applications: Automotive LIN Sensor Node, Battery-Powered IoT Sensor Endpoint, White Goods User Interface Board, Automotive Body Control Module Sub-Node, Portable Medical Monitoring Device, Industrial Sensor Transmitter.
Automotive LIN Sensor Node
The PIC16F15324-E/7NVAO is well-matched to automotive LIN sensor nodes because two EUSART modules support LIN 2.x master/slave, while the 10-bit ADC with computation (ADC^2) enables hardware threshold detection for thermistor, pressure, and position sensors without CPU wake-up. AEC-Q100 qualification allows deployment in under-hood and cabin modules where -40C to +125C operation is required. The 16-VQFN 4x4 mm footprint fits inside compact sensor housings, and PPS allows the LIN RX/TX pins to be remapped to ease PCB routing against mechanical constraints.
Recommended
Battery-Powered IoT Sensor Endpoint
For battery-powered IoT sensor endpoints, the PIC16F15324-E/7NVAO offers eXtreme Low-Power (XLP) sleep currents in the sub-microamp range, plus CLC and NCO Core Independent Peripherals that can monitor sensors and trigger events without waking the CPU. The 7 KB Flash supports BLE/Zigbee stack fragments or LoRaWAN device drivers, while 512 B SRAM is sufficient for short burst telemetry. Peripheral Pin Select routes I2C or SPI sensor interfaces to any available pin, simplifying PCB layout when the radio module occupies dedicated GPIOs.
Recommended
White Goods User Interface Board
In white-goods user-interface boards (washing machines, dishwashers, ovens), the PIC16F15324-E/7NVAO drives multiplexed 7-segment or LED matrices via its 4x PWM channels and the Complementary Waveform Generator (CWG), and reads capacitive touch or rotary encoder inputs via PPS-mappable inputs. The 5-bit DAC enables simple analog references for LED current control. With 512 B SRAM and 7 KB Flash, the device handles menu logic, button debouncing, and display refresh in a single chip, reducing BOM cost versus two-chip solutions.
Recommended
Automotive Body Control Module Sub-Node
Within automotive body control modules, the PIC16F15324-E/7NVAO functions as a sub-node MCU controlling seat adjusters, mirror positioning, ambient lighting, or HVAC flap motors. AEC-Q100 grade ensures compliance with automotive reliability standards, while the CWG generates complementary PWM outputs for H-bridge motor drivers with hardware dead-band control. The integrated comparators provide overcurrent protection by directly shutting down PWMs without CPU intervention, a critical safety feature for motor control.
Recommended
Portable Medical Monitoring Device
For portable medical monitoring such as pulse oximeters, glucose meters, and handheld thermometers, the PIC16F15324-E/7NVAO integrates the 10-bit ADC, 5-bit DAC, and analog comparators needed for sensor signal conditioning in a single chip. XLP sleep modes enable multi-month battery life on a single CR2032 cell for low-duty-cycle monitoring. The 16-VQFN 4x4 mm package supports miniaturised wearable form factors, and the PPS feature routes I2C to a small OLED display without sacrificing other pin functions.
Recommended
Industrial Sensor Transmitter
In 4-20 mA industrial sensor transmitters, the PIC16F15324-E/7NVAO digitises sensor signals with its 10-bit ADC and drives the loop using a PWM-filtered current modulator or external DAC. The extended -40C to +125C operating range handles factory floor thermal extremes, and the CLC performs autonomous threshold detection to detect broken-wire or out-of-range conditions. LIN or UART digital outputs enable integration with industrial fieldbus gateways, and AEC-Q100 qualification provides extra margin for harsh-environment reliability.

Key Differentiators
- Extended -40C to +125C operating range with AEC-Q100 qualification (vs PIC16F15324-I/7NVAO)
- 16-VQFN (4x4 mm) compact footprint for space-constrained automotive modules (vs PIC16F15324-E/SLVAO (SOIC))
- 7 KB Flash with full Core Independent Peripheral (CIP) suite including CLC, CWG, NCO (vs PIC16F15323-E/SL)
Design Notes
Place a 0.1 uF X7R decoupling capacitor within 2 mm of the VDD pin and bond the 16-VQFN exposed pad to a contiguous ground copper pour on at least the top layer. Add a 10 uF bulk capacitor at the regulator output if multiple high-current peripherals (CWG, PWMs at high frequency) are active. For battery-powered designs, route the exposed pad to a ground island that is also the thermal dissipation path; this keeps the silicon junction temperature within -40C to +125C limits.
Use Peripheral Pin Select (PPS) to remap digital peripherals (EUSART, SPI, PWM, CLC) away from analog-capable pins to reduce analog cross-coupling. Keep analog input traces short and isolated from digital switching traces. For automotive LIN designs, place the LIN transceiver as close as possible to the connector, and route the PIC MCU TX/RX lines as a short, matched differential pair to minimise EMI susceptibility and radiated emissions per CISPR 25.
Do not exceed 5.5 V on VDD even briefly during load-dump transients; add a TVS diode (e.g., SMAJ5.0CA) and a series resistor for automotive 12V-powered designs. Configure the Brown-out Reset (BOR) threshold to match your supply rail (e.g., 2.85V for 3.3V systems) to prevent Flash corruption during power-down. The PIC16F15324 has no data EEPROM - use the on-chip Flash for non-volatile storage only with wear-levelling firmware, or add an external I2C EEPROM such as 24LC256 for frequent-write parameters.
For AEC-Q100 qualification flows, retain traceability documentation: - Always order with the /VAO suffix for automotive builds. - Maintain lot date code records and supplier certificates of compliance (CoC) for PPAP submissions. - Verify that the production board design matches the qualified BOM exactly; any peripheral changes (crystal, decoupling) may require re-qualification. Microchip provides PPAP and IMDS support documentation on request through authorised distributors.
