PIC16F15345T-E/SSVAO Overview
What is a PIC 8-bit microcontroller? A PIC microcontroller is a single-chip computer based on a RISC Harvard architecture that combines a CPU, Flash program memory, RAM, EEPROM data memory, and configurable peripherals. The PIC16F153xx family specifically targets low-power (XLP) designs with autonomous CIPs that offload tasks like waveform generation, signal conditioning, and communication from the core, reducing active CPU time and extending battery life.
Key features include 14KB Flash program memory, 1KB SRAM, 256B EEPROM, 18 general-purpose I/O pins, four 10-bit PWM outputs, a 10-bit ADC with up to 17 channels, a 5-bit DAC, two comparators with rail-to-rail inputs, two Enhanced USARTs, one SPI and one I2C, and eXtreme Low-Power (XLP) technology with typical sleep currents below 1 uA. The 32 MHz internal oscillator eliminates the need for an external crystal in many designs.
Architecturally, the device uses a 14-bit instruction word, a modified Harvard memory layout, and Microchip's CIP block to execute peripheral interactions in hardware. The CWG, PWM, ADC, comparator, and DAC can be chained together without CPU intervention, making it well suited to motor control, lighting, and sensor front-end designs.
Typical applications include automotive body and sensor nodes, IoT edge sensor nodes, LED lighting controllers, small BLDC and fan drivers, and consumer appliance user interfaces. The combination of AEC-Q100, wide temperature range, and SSOP-20 footprint makes it especially attractive for in-cabin automotive ECUs and HVAC controls.
When designing, note that the 'E' temperature grade and 'VAO' suffix designate the automotive qualified (-40C to +125C) variant in tape-and-reel packaging. Always confirm pin assignment against the SSOP-20 diagram because the automotive grade adds specific test coverage that distinguishes it from the standard PIC16F15345-I/SS.

Typical Applications
PIC16F15345T-E/SSVAO is suitable for 6 applications: Automotive Body Control Module, HVAC Sensor Interface ECU, IoT Edge Sensor Node, LED Lighting Controller, Small BLDC / Fan Motor Driver, Consumer Appliance User Interface.
Automotive Body Control Module
The PIC16F15345T-E/SSVAO fits automotive body controllers because its AEC-Q100 qualification and -40C to +125C operating range meet OEM automotive stress-test requirements. The 18 I/O pins handle low-side driver outputs, switch inputs, and LIN bus monitoring, while the CWG and 10-bit ADC support LED matrix and ambient light sensing. With 14 KB Flash and Core Independent Peripherals, the MCU can run both body-control and lighting logic without an extra companion chip, reducing BOM cost by approximately 30% versus two-chip solutions.
Recommended
HVAC Sensor Interface ECU
The PIC16F15345T-E/SSVAO serves well in HVAC climate-control sensor interface ECUs thanks to its 10-bit ADC with multiple input channels, two comparators, and 5-bit DAC for actuator drive. The four PWM channels can directly drive blower-motor speed controllers without an external PWM generator. XLP sleep currents below 1 uA let the module remain ignition-off while still monitoring cabin temperature, preserving battery life during long parking periods typical of fleet and EV applications.
Recommended
IoT Edge Sensor Node
For battery-powered IoT sensor nodes, the PIC16F15345T-E/SSVAO offers 14 KB Flash for application code plus TCP/HTTP or LoRaWAN MAC stacks, 1 KB SRAM for buffering, and 256 B EEPROM for calibration data. The two EUSARTs allow simultaneous sensor uplink and debug-port access, while XLP technology drops quiescent current below 1 uA in sleep. The 32 MHz internal oscillator eliminates external crystals, reducing node BOM and PCB area by roughly 20%.
Recommended
LED Lighting Controller
The PIC16F15345T-E/SSVAO is well matched to constant-current LED drivers because the Complementary Waveform Generator (CWG) and four 10-bit PWM channels produce phase-correct, dead-band-controlled switching waveforms for buck and boost LED topologies. The 5-bit DAC and comparators form a hardware feedback loop for current regulation. With 32 MHz of CPU bandwidth, color-mixing and DMX/RDM parsing run in software without external logic.
Recommended
Small BLDC / Fan Motor Driver
Sensorless BLDC and small fan controllers benefit from the PIC16F15345T-E/SSVAO's CWG and four PWMs, which together generate the 6-step commutation waveforms for three-phase drives. The 10-bit ADC samples back-EMF for commutation timing, while the comparators trigger protection on overcurrent events. With AEC-Q100, the same firmware can serve automotive cooling fans and HVAC blower applications.
Recommended
Consumer Appliance User Interface
In washing machines, dishwashers, and microwave ovens, the PIC16F15345T-E/SSVAO handles capacitive-touch key scanning via the on-chip comparators, drives 7-segment or matrix LED displays through the four PWMs, and maintains real-time-clock-style timing through the 32 kHz internal oscillator. The 14 KB Flash accommodates multilingual UI strings plus motor-control state machines, eliminating a second MCU. The SSOP-20 footprint simplifies layout in compact appliance enclosures.

Key Differentiators
- Tape-and-reel packaging aligned to high-volume automotive SMT lines (vs PIC16F15345-E/SS)
- AEC-Q100 production-test variance via 'VAO' suffix (vs PIC16F15345T-E/SS)
- Highest-density automotive-qualified 8-bit PIC in the 153xx family (vs PIC16F15344T-I/SS)
Design Notes
The PIC16F15345T-E/SSVAO is an F-series variant operating from 3 V; do not connect 5 V directly to VDD. Place a 100 nF decoupling capacitor as close as possible to pins 17 (VDD) and 5/18 (VSS) to suppress switching transients from the internal oscillator and PWM edges. For noisy automotive environments, add a 10 uF bulk capacitor near the regulator output to handle cold-crank dips down to 4 V on a 12 V rail.
At 32 MHz active and 3 V supply, the core draws approximately 5 mA (estimated: 0.15 mA/MHz x 32 MHz), giving 15 mW of dissipation - well within the SSOP-20 thermal limit of roughly 800 mW. However, in sealed automotive enclosures at +85C ambient, derate by 0.7 to stay within the +125C junction ceiling. Forced airflow is not required for typical GPIO loads.
Keep the VPP/RA3 pin (pin 1) accessible or routed to an in-circuit programming header, since this pin doubles as the high-voltage programming entry. Avoid long traces on the ICSPDAT and ICSPCLK lines - keep them under 50 mm and shield with ground to prevent programming failures in electrically noisy automotive harnesses.
Do not confuse the SSOP-20 footprint (0.209" / 5.30 mm body) with the wider SOIC-20 (0.300" / 7.50 mm body). The PIC16F15345-I/SO uses SOIC-20 and will not fit a SSOP-20 land pattern. When migrating from industrial to automotive grade, confirm both footprint AND the 'E' vs 'I' temperature code in the part number.
