PIC16F18325T-E/7NVAO Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), EEPROM, and peripherals on one die. Within the PIC® taxonomy, the PIC16F family targets mid-density low-power applications; the XLP™ branding indicates an Extreme Low Power variant featuring nanoWatt sleep currents. This MCU sits in the power management hierarchy as an always-on controller that supervises sensors and actuators while consuming minimal quiescent current.
Key differentiating features of the PIC16F18325T-E/7NVAO include a maximum CPU clock of 32 MHz, 12/18 I/O pins with Peripheral Pin Select (PPS) remapping, 10-bit PWM with CCP, CWG and CLC core independent peripherals, plus NCO, two EUSART modules, two I2C and two SPI interfaces. The 'T' tape-and-reel suffix and '/7N' designator identify the 16-VQFN package option, while 'VAO' marks the automotive qualification suffix per Microchip's ordering convention.
Architecturally, the device uses an enhanced mid-range PIC16 core with a hardware multiplier, two hardware stacks, and a deep sleep mode that draws nanoamps. CIP (Core Independent Peripheral) blocks such as the CWG, CLC and NCO allow autonomous operation without CPU wake-up, enabling deterministic low-latency responses while preserving the XLP™ current budget.
Typical applications include automotive body and chassis ECUs, sensor nodes, low-power IoT battery devices, LED lighting controllers, and LIN slave nodes. The combination of PPS, 10-bit ADC, and small VQFN-16 footprint suits space-constrained designs.
When designing with this part, allocate the exposed pad as a thermal and ground pad with adequate via stitching. AEC-Q100 grade 0 ambient temperature range allows under-hood placement. Use MPLAB X IDE with XC8 compiler for development.

Typical Applications
PIC16F18325T-E/7NVAO is suitable for 7 applications: Automotive Body Control Module, Battery-Powered IoT Sensor Node, LED Lighting Controller, LIN Bus Slave Node, Industrial Sensor Interface, Consumer Remote Control, Touch-Sense User Interface.
Automotive Body Control Module
The PIC16F18325T-E/7NVAO suits automotive BCM applications thanks to its AEC-Q100 qualification, -40C to +125C operating range, and 14KB Flash for body-control state machines. The 10-bit ADC reads switch and sensor inputs while the 10-bit PWM drives LED loads directly. Core Independent Peripherals (CLC, CWG, NCO) handle timing-critical events autonomously, so the CPU can remain in XLP™ nanoWatt sleep, meeting strict quiescent-current budgets. The 16-VQFN (4x4) footprint fits space-constrained BCM PCBAs and the exposed pad provides adequate thermal dissipation for the under-hood environment.
Recommended
Battery-Powered IoT Sensor Node
With XLP™ technology and Core Independent Peripherals, the PIC16F18325T-E/7NVAO enables years of battery life on a single coin cell. The MCU wakes from sleep on a PPS-mapped GPIO edge, runs the CLC to acquire a sensor reading, and returns to sleep without CPU intervention - keeping active time under microseconds. 14KB Flash fits small MQTT-SN or BLE beacon stacks, and 1KB RAM buffers payloads. The AEC-Q100 grade is overkill for stationary sensors but ensures reliability in thermally-challenged deployments. 16-VQFN (4x4) supports dense module layouts.
Recommended
LED Lighting Controller
The PIC16F18325T-E/7NVAO drives multi-channel LED strings with its 10-bit PWM and Complementary Waveform Generator (CWG). Up to 12 PPS-remappable I/O pins can drive LED drivers or directly switch FETs, while the Numerically Controlled Oscillator (NCO) provides precise dimming frequencies. The 32 MHz CPU executes scene logic while XLP™ sleep sustains battery-backed emergency LED modes. AEC-Q100 grade suits automotive interior ambient lighting and architectural lighting controllers requiring long-term reliability. The 16-VQFN footprint plus exposed pad eases thermal extraction.
Recommended
LIN Bus Slave Node
The PIC16F18325T-E/7NVAO functions as a LIN slave in automotive body networks, using one of its two EUSART peripherals as the LIN physical interface. PPS remapping routes the LIN TX/RX signals to any GPIO, simplifying PCB routing when LIN bus pins are constrained. 14KB Flash holds the LIN 2.x protocol stack and application code, while 256 bytes of EEPROM store node configuration and diagnostics. AEC-Q100 qualification is mandatory for OEM automotive modules. Core Independent Peripherals handle bus timing without CPU load, ensuring deterministic LIN response.
Recommended
Industrial Sensor Interface
Industrial 4-20 mA or 0-10V sensor front-ends use the PIC16F18325T-E/7NVAO's 10-bit ADC and PGA peripherals for signal conditioning. PPS lets designers route analog inputs to any pin, easing PCB layout. Two EUSART, two I2C, and two SPI peripherals simultaneously support HMI displays, digital sensors and isolated communication links. The CLC and NCO peripherals handle PWM-to-analog reconstruction or quadrature decoding in motion-control feedback loops. AEC-Q100 grade enables deployment in factory automation cabinets and process-control skids.
Recommended
Consumer Remote Control
Voice, IR, or BLE remote controls benefit from the PIC16F18325T-E/7NVAO's XLP™ nanoWatt sleep, 32 MHz performance, and PPS-driven keypad scanning. The CWG peripheral produces IR carrier waveforms while CLC decodes incoming signals autonomously, eliminating CPU wake-up on every button event. 14KB Flash accommodates button-mapping tables and consumer protocol stacks (RC5, SIRC, NEC). The 16-VQFN (4x4) package fits thin remote housings and the AEC-Q100 grade is welcome insurance for long-life consumer products.
Recommended
Touch-Sense User Interface
The PIC16F18325T-E/7NVAO's mTouch capacitive-touch peripheral and CLC blocks allow button, slider, and proximity sensing without CPU intervention. Charge-time measurement on any PPS-remappable I/O pin simplifies PCB sensor layout. The NCO drives haptic feedback or LED status while the CPU remains asleep, maximizing battery life in IoT and wearable applications. AEC-Q100 grade supports automotive interior touch surfaces. 14KB Flash holds button-mapping firmware and gesture logic.

Key Differentiators
- Same die in tape-and-reel packaging for high-volume automotive lines (vs PIC16F18325-E/7NVAO)
- Automotive temperature grade with -40C to +125C support (vs PIC16F18325T-I/7N)
- Larger Flash memory tier than PIC16F18324T-E/7NVAO (vs PIC16F18324T-E/7NVAO)
- Smaller Flash for cost-sensitive designs (vs PIC16F18326T-E/7NVAO)
Design Notes
The 16-VQFN (4x4 mm) package exposes a thermal pad beneath the die that must be soldered to a copper pour on the PCB. Stitch the thermal pad to the ground plane with an array of 0.3 mm thermal vias (9-12 vias is typical). Without proper soldering the device will overheat at elevated ambient temperature and may exhibit ADC accuracy drift per the Microchip layout guidelines.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 8), and a bulk 1 uF to 4.7 uF ceramic on the supply rail feeding the MCU. The PIC16F18325T-E/7NVAO uses nanoWatt sleep modes with sub-uA quiescent draw; ensure any series ferrite bead is sized to maintain logic-low VDD in deep sleep to avoid unintended resets. AEC-Q100 PPAP documentation requires worst-case supply ramp testing.
When migrating from PIC16F18325-E/7NVAO (industrial grade) to PIC16F18325T-E/7NVAO (AEC-Q100 automotive), the firmware is bit-for-bit identical but the temperature grade differs (-40C to +85C vs -40C to +125C). Do not substitute an -I/7N part into an automotive module - this will fail OEM PPAP. Also note that PPS peripheral mapping registers differ between PIC16F1832x sub-variants; always re-validate the configuration bits table when porting firmware.
PPS remapping routes any digital peripheral to any GPIO, but analog functions (ADC, comparators) remain pin-locked. When using EUSART, I2C, or SPI in high-speed modes, keep trace lengths under 50 mm and avoid routing signal traces parallel to switching power converter nodes. The exposed pad provides a low-impedance return path - do not split the ground plane beneath the VQFN footprint.
