PIC16F15325T-E/SLVAO Overview
A microcontroller (MCU) is a single-chip computer that combines a CPU, non-volatile program memory, working RAM, and programmable peripherals. Within Microchip's portfolio, the PIC16F153xx family sits at the lower-flash end of the PIC16F1 enhanced mid-range line, between the PIC16F152xx family (smaller memory) and PIC16F188xx family (larger memory and richer peripherals). All of these families belong to the broader PIC16F 8-bit microcontroller category, which is itself a subset of Microchip's eXtreme Low-Power (XLP) branded product line designed for battery-powered and energy-harvesting applications.
Key features include Core Independent Peripherals (CIPs) such as configurable logic cells, signal measurement timers, and the CWG, which allow hardware-driven tasks to run without CPU intervention. Two Enhanced USART modules, one SPI, and one I2C master/slave bus cover mainstream serial communications. The device operates from 2.3 V to 5.5 V across -40 °C to +125 °C, ships in a 14-pin SOIC (SL) package, and is qualified to the AEC-Q100 grade 1 automotive standard as indicated by the VAO suffix.
The architecture combines a RISC-style Harvard bus with an 8-level hardware stack and a wide peripheral set, which simplifies firmware while keeping interrupt latency low. With XLP technology, sleep current drops into the nanoamp range, allowing the MCU to be duty-cycled in battery applications.
Typical applications include automotive body electronics (interior lighting, seat controllers, HVAC flaps), industrial sensor nodes and small motor control, consumer appliances and remote controls, low-cost IoT end nodes with serial connectivity, and white-goods user-interface boards where the ADC2, DAC, and CWG simplify analog front-end and PWM signal generation.
When designing with this part, note that 'VAO' designates an automotive-grade variant; ensure the Q1 / AEC-Q100 qualification is acceptable for your end system, and plan the SOIC-14 PCB footprint with thermal copper for AEC-Q100 thermal-stress margin.

Typical Applications
PIC16F15325T-E/SLVAO is suitable for 7 applications: Automotive Interior Lighting Controllers, HVAC Actuator and Flap Control, Seat Control and Memory Switch Modules, Low-Cost IoT Sensor End Nodes, White-Goods User Interface Boards, Industrial Sensor Signal Conditioning, Small Motor Control and Fan Drivers.
Automotive Interior Lighting Controllers
The PIC16F15325T-E/SLVAO suits automotive interior lighting modules (dome lights, ambient RGB strips, puddle lamps) where AEC-Q100 Grade 1 qualification is mandatory. Its four 10-bit PWM channels drive LED drivers or MOSFET high-sides with hardware-complementary dead-band control via the on-chip Complementary Waveform Generator (CWG), eliminating software timing jitter. ADC2 with computation samples ambient light sensors without CPU intervention, while eXtreme Low-Power (XLP) sleep currents in the nanoamp range let the MCU remain wake-capable on quiescent CAN/LIN networks. The 14-pin SOIC footprint fits compact PCBAs behind roof consoles, with the tape-and-reel 'T' suffix supporting high-volume SMT lines.
Recommended
HVAC Actuator and Flap Control
HVAC mode and recirc flap motors need a small AEC-Q100-qualified MCU that can drive a brushed DC motor or stepper through half-H or full-H bridges. The PIC16F15325T-E/SLVAO's CWG + 10-bit PWM + 2-comparator hardware engine implements commutation and current limiting without CPU load, leaving headroom for LIN slave communication via the on-chip EUSART. The 5-bit and 8-bit DAC outputs set analog reference points for thermistor-conditioned set-point curves. Its -40 °C to +125 °C operating range covers under-dash and head-unit environments, and the SOIC-14 footprint fits tight PCBAs adjacent to blower housings.
Recommended
Seat Control and Memory Switch Modules
Automotive seat-position memory modules integrate the PIC16F15325T-E/SLVAO with Hall sensors and small brushed DC motors. ADC2 with hardware averaging reads multiple position sensors simultaneously, while the CWG generates phase-shifted PWMs for H-bridge drivers. The on-chip 5/8-bit DAC produces bias voltages to offset Hall-effect sensor nulls. AEC-Q100 Grade 1 ensures PPAP and end-of-line test consistency, while 256 B of EEPROM stores nonvolatile seat memory positions. With 12 GPIO pins available in the SOIC-14 package, the design supports up to six seat-direction switches without a port expander.

Low-Cost IoT Sensor End Nodes
Battery-powered IoT nodes such as environmental monitors and asset trackers benefit from the PIC16F15325T-E/SLVAO's XLP technology, where sleep current drops to the nanoamp range and wake-up is handled by a hardware Real-Time Clock or interrupt on change. The 14 KB Flash holds a small protocol stack (Modbus RTU, MQTT-SN, LoRaWAN Class A) plus application firmware. The 1 KB RAM supports RTOS-style or super-loop designs, while SPI and I2C master interfaces connect to sensors. Operating from 2.3 V to 5.5 V makes the part compatible with 3.3 V sensors and 5 V solar battery packs alike.

White-Goods User Interface Boards
Washing machines, dryers, and dishwashers use the PIC16F15325T-E/SLVAO to drive segmented LCD or LED indicators, capacitive touch buttons, and rotary encoder inputs. The CWG and four PWMs control buzzer tones and indicator LEDs while 12 GPIO pins scan 4x4 key matrices without external logic. ADC2 evaluates NTC temperature probes in real time, while the comparators detect water-level sensor thresholds. The 256-byte EEPROM stores user preferences and error-history logs, and the 14-pin SOIC package simplifies conformal-coated PCBA designs by keeping the BOM minimal.
Recommended
Industrial Sensor Signal Conditioning
Process-control analog front-ends benefit from the PIC16F15325T-E/SLVAO's 10-bit ADC2, 5/8-bit DAC, and dual comparators in a single 14-pin SOIC. The MCU can be programmed as a stand-alone smart sensor transmitter (4-20 mA loop-powered via shunt) with on-die EEPROM calibration storage. The CWG generates excitation signals for strain-gauge bridges, while SPI/EUSART channels feed isolated field-bus drivers. The -40 °C to +125 °C operating range covers outdoor and unheated-cabinet industrial installations.
Recommended
Small Motor Control and Fan Drivers
Brushless DC (BLDC) fans, small pumps, and vibration motors are driven directly by the PIC16F15325T-E/SLVAO using its Complementary Waveform Generator (CWG), four PWMs, and dual comparators for back-EMF zero-cross detection. The on-chip 8-bit DAC sets PWM dead-band and reference thresholds, while ADC2 monitors motor current via a sense resistor. The 14-pin SOIC is small enough to embed inside the motor housing, and the eXtreme Low-Power (XLP) sleep modes reduce standby power below 50 nA, satisfying EU eco-design standby limits.

Key Differentiators
- Tape-and-reel + AEC-Q100 Grade 1 in a single part (vs PIC16F15324T-I/SL)
- Largest Flash within PIC16F153xx SOIC-14 family (vs PIC16F15313T-I/SL)
- On-die CIP peripherals reduce firmware footprint (vs PIC16F15224-I/ST (TSSOP-20 not SOIC-14))
Design Notes
Decouple the VDD pin with a 100 nF X7R ceramic capacitor placed within 2 mm of the supply pin, plus a bulk 4.7-10 µF tantalum or ceramic on the same rail. For AEC-Q100 designs, select capacitors rated -55 °C to +125 °C and follow Microchip's application note AN1217 on decoupling small SOIC microcontrollers. Use the XLP Sleep mode (SLEEP<0>) plus Interrupt-on-Change to drop quiescent current to the nanoamp range for battery-powered IoT end nodes.
The SOIC-14 package has a typical junction-to-ambient thermal resistance of approximately 70-90 °C/W. For AEC-Q100 Grade 1 designs at ambient temperatures of +85 °C to +125 °C, ensure the absolute worst-case CPU current consumption stays below ~30 mA to keep junction temperature rise below 50 °C. Add a small thermal copper-pour under the exposed pad region (die attach paddle) and several vias to a back-side copper pour per AN1078 if high duty-cycle PWM is required.
Route the ICSPCLK and ICSPDAT traces to dedicated test points to support in-circuit serial programming on the production line. Keep the MCLR/RA3 pin pulled to VDD through a 10 kΩ resistor with a 100 nF decoupling capacitor to GND for in-circuit programming. Reserve a small ground-return zone under the MCU to keep analog ADC traces over a clean reference. For EMI-sensitive automotive designs, place a 4.7-22 µF bulk capacitor near each cluster of peripheral loads.
Do not configure the CWG and standard PWM on the same pin without verifying alternate-function assignments - the CWG overrides the PWM and may lock the pin if not properly sequenced. When migrating from PIC16F15325-E/SLVAO (tube) to PIC16F15325T-E/SLVAO (tape & reel), ensure the pick-and-place feeder is configured for 16 mm-width SOIC-14 reels. Avoid driving LEDs directly from MCU GPIO above 5 V - use a current-limiting resistor and a transistor driver. For VAO (AEC-Q100 Grade 1) applications, follow Microchip's PPAP and traceability requirements on incoming material.
For EUSART/SPI/I2C buses above 1 MHz, add 30-50 Ω source-series resistors on clock outputs and ensure trace stubs are minimized. Keep ADC traces away from switching regulator or PWM traces, route analog grounds through a star-point to VSS, and use the internal ADC's hardware-averaging mode (ADC2 rolling average) to reject noise from nearby digital signals. Cap the DAC outputs with a 100 nF X7R load if they drive external op-amp reference inputs.
