PIC16F18325-E/7NVAO Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), non-volatile EEPROM and a configurable set of peripherals behind a set of digital and analog I/O pins. Within the broader semiconductor taxonomy, MCUs sit above simple logic ICs and below microprocessors (MPUs); PIC microcontrollers from Microchip occupy the 8-bit mid-range / enhanced mid-range niche, characterized by deterministic instruction execution, small footprint packages and very low active and sleep currents (XLP). The PIC16F18325 belongs to the PIC16F1xxx enhanced mid-range family, which added CLC, NCO and PPS hardware that previously required external logic or a larger device.
Key differentiating features include 14KB self-programmable Flash with device firmware upgrade support, 256B EEPROM for user-data storage, 1KB SRAM for variables and stack, and Core Independent Peripherals (CIPs) such as CWG (Complementary Waveform Generator) and NCO (Numerically Controlled Oscillator) that offload tasks from the core. PPS allows most digital peripherals to be remapped to a wide choice of pins, simplifying PCB layout and enabling a single PCB to be reused across multiple product variants. The AEC-Q100 qualification is the primary differentiator vs the commercial-grade PIC16F18325-I/... siblings.
The internal architecture is a modified Harvard 8-bit RISC core with a 32-level hardware stack and 49-instruction instruction set, supported by a 2-phase instruction pipeline and a 32MHz internal oscillator. Analog capabilities include a 10-bit ADC with computation, comparators and a Fixed Voltage Reference; digital intelligence is provided by the CLC, NCO and CWG blocks that can implement logic, frequency generation and half-bridge timing without CPU intervention. This combination yields very low power consumption in sleep modes while keeping complex timing tasks fully hardware-driven.
Typical applications include automotive body controllers, sensor interface modules, LIN nodes, LED lighting drivers and low-power IoT edge devices. The AEC-Q100 grade plus 14KB Flash and PPS flexibility is well matched to LIN-based body-electronics slaves and small motor/lighting controllers that must run from a 12V automotive rail while drawing minimal quiescent current.
When designing with this part, budget the 16-VQFN exposed pad as the primary thermal path; tie the EP to ground with a via array under the pad. Use PPS to clean up any last-minute pinout changes without respinning the PCB, and select the -E industrial / automotive grade when the target environment exceeds 85C ambient. Finally, confirm the supply voltage range in the manufacturer datasheet before using this MCU directly off a 5V rail, because the '3V' nominal figure covers a wider family window.

Typische Anwendungen
PIC16F18325-E/7NVAO ist geeignet für 6 Anwendungs: Automotive Body Control Module, LIN Sensor Node, LED Lighting Controller, Small BLDC / Fan Controller, Industrial Sensor Hub, Automotive Switch / Keypad Interface.
Automotive Body Control Module
The PIC16F18325-E/7NVAO is well suited to automotive body controllers thanks to its AEC-Q100 qualification, -40C to +125C operating range, and Core Independent Peripherals. The 14KB Flash and 1KB RAM comfortably host a LIN slave stack plus body-electronics logic, while the 256B EEPROM stores node configuration and calibration constants across power cycles. PPS allows the same PCB to be reused across multiple SKUs by remapping UART, PWM and CWG outputs to different physical pins, reducing SKU proliferation. The 16-VQFN exposed pad gives a compact 3x3 mm footprint with low thermal resistance, ideal for space-constrained door-module or mirror-controller boards.
Empfohlen
LIN Sensor Node
For LIN-attached sensor nodes such as temperature, humidity or position sensors, the PIC16F18325-E/7NVAO provides a self-contained MCU with on-chip 10-bit ADC, comparators and a Fixed Voltage Reference. The XLP sleep currents (per Microchip datasheet) allow battery-powered sensor nodes to meet automotive quiescent-current budgets, while the CLC and NCO blocks offload sensor-signal conditioning from the core so the CPU can remain in sleep longer. The VQFN-16 footprint and AEC-Q100 grade make this part a reliable drop-in for distributed sensor networks behind a body-domain or gateway ECU.
Empfohlen
LED Lighting Controller
The PIC16F18325-E/7NVAO's CWG (Complementary Waveform Generator), 10-bit PWM and NCO make it a strong fit for automotive interior and exterior LED lighting controllers, including RGB ambient lighting and sequential turn indicators. The CWG can drive a half-bridge MOSFET stage with hardware dead-band generation, while multiple PWM channels provide dimming and color mixing without CPU overhead. PPS lets designers route each PWM channel to the most convenient physical pin, simplifying PCB layout when LEDs and connectors are spread across the board. AEC-Q100 qualification and the -40C to +125C range cover under-hood and exterior lighting thermal envelopes.
Empfohlen
Small BLDC / Fan Controller
For small brushless-DC fans and pumps in automotive HVAC and cooling applications, the PIC16F18325-E/7NVAO offers enough compute and analog peripherals for sensorless trapezoidal commutation. The CLC can implement zero-cross detection and the NCO can synthesize the commutation timer entirely in hardware, freeing the CPU to handle speed-command UART/LIN traffic and fault diagnostics. The 14KB Flash accommodates state-machine plus fault-logging code, and the 256B EEPROM stores trim values learned during end-of-line calibration. The VQFN-16 footprint and AEC-Q100 grade keep the design compact and qualified for under-hood environments.
Empfohlen
Industrial Sensor Hub
Outside the automotive segment, the PIC16F18325-E/7NVAO also serves as an industrial sensor hub where extended temperature and reliable peripherals are required. The 10-bit ADC with computation, comparators and a Fixed Voltage Reference can read multiple analog sensors with on-chip oversampling and averaging, while I2C/SPI/EUSART peripherals connect to external digital sensors. PPS allows the same firmware binary to support several board revisions by remapping peripheral pins, which simplifies NPI and obsolescence management. The 16-VQFN package fits on small PCBs behind industrial connectors, and XLP sleep currents help meet battery-backed or energy-harvesting power budgets.
Empfohlen
Automotive Switch / Keypad Interface
The PIC16F18325-E/7NVAO is well matched to automotive switch and keypad input modules that need debounced GPIO, LIN/UART communication, and AEC-Q100 reliability. The 12-18 I/O pins can scan a 4x4 or larger matrix keypad or rotary encoder, with the CLC implementing the debounce and edge-detection logic in hardware so the CPU remains in sleep until a valid event occurs. The on-chip EEPROM retains key-press counters and configuration across battery disconnects, and PPS lets the designer route the LIN/UART pins to whatever edge-connector position is convenient. The VQFN-16 package and -40C to +125C range fit comfortably behind a door-switch or center-console switch panel.

Wichtigste Unterscheidungsmerkmale
- AEC-Q100 qualification with -40C to +125C operating range in a 16-VQFN exposed-pad package (vs. PIC16F18325-E/7N)
- 14KB Flash headroom for LIN stacks plus application logic (vs. PIC16F18324-E/7NVAO)
- 1KB SRAM for richer protocol buffers (vs. PIC16F18323-E/7N)
Designhinweise
The 16-VQFN exposed-pad package relies on the EP for both the ground reference and the primary thermal path. Per the Microchip PIC16F18325 family datasheet, the EP must be soldered to a PCB land pattern with a via array (typically 4-9 thermal vias) tied to the inner ground plane. Skipping the EP soldering or using too few thermal vias will increase theta_JB and may push the junction temperature above the -40C to +125C automotive limit under sustained load.
Although the PIC16F18325 family is specified at a nominal 3V supply, the verified listing indicates a typical operating range across the family that supports common 3.3V and 5V rails used in automotive body modules. According to Microchip datasheet guidance, place a 100nF decoupling capacitor within 3 mm of each VDD pin and a bulk 1uF-10uF capacitor near the IC. For battery-backed modules, leverage the XLP sleep modes (down to tens of nA per datasheet) to meet quiescent-current budgets; route the MCLR line through a weak pull-up rather than tying it directly to VDD to keep in-circuit serial programming possible.
Use Peripheral Pin Select (PPS) to assign digital peripherals (EUSART, SPI, I2C, PWM, CWG, CLC) to the most PCB-friendly pins, and lock those assignments in the configuration bits so they are not accidentally remapped by user code. According to the PIC16F18325 family datasheet, PPS must be unlocked before each write and re-locked afterward to prevent runaway code from corrupting peripheral routing. Route the ICSP pins (RB6/ICSPCLK and RB7/ICSPDAT) to a 6-pin header even on production boards to enable field firmware updates without removing the MCU.
