PIC16F15355-I/SSVAO 개요
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), and a mix of digital and analog peripherals. PIC® MCUs use a modified Harvard RISC architecture, executing one instruction per clock cycle for deterministic, low-power embedded control. Within the broader power management and embedded hierarchy, an MCU sits at the lowest firmware-driven layer: above it are microprocessors, SoCs, and application processors. The 8-bit PIC16 family specifically targets cost- and power-sensitive applications where 32-bit performance is not required.
The PIC16F15355-I/SSVAO integrates Intelligent Analog peripherals (10-bit ADC, 5-bit DAC, comparators), Core Independent Peripherals (CIPs) such as Configurable Logic Cells and PWMs, and Microchip's eXtreme Low-Power (XLP) technology that delivers sub-uA sleep currents. The 28-pin SSOP footprint with 0.65mm pitch is one of the most widely used automotive MCU packages, enabling direct PCB reuse across PIC16F15344/15345/15354 family variants.
Typical applications include automotive body control modules, sensor signal conditioning nodes, low-power IoT sensor hubs, LED lighting controllers, and small motor/valve drivers. CIPs allow timer-driven state machines that offload work from the CPU, lowering average current and enabling years of operation from a single battery.
When designing with this part, evaluate whether the application truly needs automotive-grade qualification (AEC-Q100) versus the standard PIC16F15355-I/SS. The VAO variant is typically 20-40% more expensive and has longer lead times, so reserve it for automotive-grade projects.

일반적인 애플리케이션
PIC16F15355-I/SSVAO 적합 용도: 6 애플리케이션s: Automotive Body Control Modules, Automotive Sensor Signal Conditioning, Battery-Powered IoT Sensor Hubs, LED Lighting Controllers, Small DC Motor / Valve Drivers, Automotive LIN Slave Nodes.
Automotive Body Control Modules
The PIC16F15355-I/SSVAO is well-suited for automotive body control modules such as door, window, mirror, and seat controllers that require AEC-Q100 qualification. Its 32 MHz core provides enough MIPS to handle LIN bus protocol stacks plus firmware-driven actuator logic, while 14 KB Flash comfortably accommodates full LIN state machines plus calibration tables. CIPs like CLC and PWM offload repetitive state-machine work from the CPU, lowering average current draw during idle. The 28-SSOP footprint has been used across PIC16F153xx family generations, giving designers a migration path to PIC16F15356-I/SSVAO for future feature growth. Estimated: at 5V and 32 MHz active with 50% duty cycle, typical core current is 2-3 mA, allowing sub-3 mA average for LIN-listen duty.

Automotive Sensor Signal Conditioning
The PIC16F15355-I/SSVAO is commonly deployed as a smart-sensor front-end for temperature, pressure, and humidity sensors in automotive and industrial environments. Its 10-bit ADC with multiple channels accepts inputs from bridge sensors, while the 5-bit DAC enables offset trimming and stimulus generation. The on-chip temperature sensor and comparator provide built-in diagnostics for sensor health checks required by automotive SPICE- and ASIL-rated modules. XLP sub-uA sleep current supports battery-backed sensor nodes that must run for years on coin-cell or single-cell Li-ion power. The AEC-Q100 VAO suffix confirms it meets automotive reliability standards for underhood, cabin, and chassis mounting positions.
추천
Battery-Powered IoT Sensor Hubs
The PIC16F15355-I/SSVAO, while automotive-qualified, is also a strong fit for low-power IoT sensor hubs operating from 2.3-5.5 V supplies where automotive-grade reliability is desired. XLP technology delivers sub-uA sleep currents, and the integrated 32 MHz HFINTOSC eliminates the need for an external crystal in many designs. CLCs and NCO can implement wake-on-event timing without the CPU active, reducing average system current to the uA range for battery-life estimates measured in years. The 28-SSOP package is hand-solder-friendly and compatible with hand-prototype as well as high-volume reflow assembly. When automotive qualification is not required, the non-VAO PIC16F15355-I/SS offers the same silicon at lower cost.
추천
LED Lighting Controllers
The PIC16F15355-I/SSVAO drives multi-channel LED controllers for automotive ambient lighting, architectural lighting, and industrial signage. Its CIP-based PWM peripherals generate multi-channel phase-shifted PWM outputs without CPU intervention, supporting smooth color-mixing transitions and dimming curves. The 10-bit ADC reads ambient-light sensors for daylight harvesting, while the 5-bit DAC provides bias voltages for constant-current LED drivers. AEC-Q100 qualification makes it suitable for interior cabin lighting, underbody accent lighting, and headlamp leveling. Combined with the 32 MHz core, the MCU implements DALI, DMX512, or LIN-based control protocols in firmware with no external protocol IC.
추천
Small DC Motor / Valve Drivers
The PIC16F15355-I/SSVAO is a frequent choice for small DC motor, stepper, and solenoid-valve drivers in automotive body and HVAC systems. Complementary PWM outputs drive half-bridges for brushed DC motors up to 1-2 A (with external FETs), while the 10-bit ADC reads motor current via shunt amplifiers for closed-loop torque control. The on-chip comparator enables hardware over-current protection that trips without CPU latency. The CIP suite implements trapezoidal commutation for stepper motors directly in hardware, leaving the CPU free to manage communication stacks. AEC-Q100 qualification ensures reliable operation in underhood thermal environments up to 125C in the E-grade version.
추천
Automotive LIN Slave Nodes
The PIC16F15355-I/SSVAO is a top-pick microcontroller for automotive LIN (Local Interconnect Network) slave nodes that require AEC-Q100 qualification. Its EUSART supports LIN 2.x protocol auto-baud detection, and the 32 MHz core leaves sufficient MIPS for full LIN schedule table handling plus application logic. The 14 KB Flash accommodates LIN state machines, node capability files (NCFs), and customer application code. The 28-SSOP package is hand-prototype-friendly, and XLP sub-uA sleep current keeps the average draw under 100 uA during LIN bus silence, satisfying automotive quiescent-current specs. Designers can migrate upward to PIC16F15356-I/SSVAO when adding CAN FD gateway features.

설계 노트
Estimated: the 28-SSOP package has typical theta_JA of 100-110 C/W in still air. At 32 MHz active and 5V VDD, core current is roughly 4-5 mA, yielding 20-25 mW internal dissipation. Even at ambient 85C, junction rise is only 2-3 C above ambient, so no heatsink is required. For the E-grade (125C) VAO variant in sealed enclosures, ensure at least 50 mm^2 of PCB copper tied to VDD/VSS for additional thermal spreading.
Decouple VDD (pin 19) with a 100 nF ceramic capacitor placed within 3 mm of the pin, plus a bulk 1-10 uF tantalum or ceramic on the VDD rail. Tie AVDD (pin 28) to VDD with a 100 nF + 1 uF LC-filtered analog supply for best ADC performance. Use Microchip's MPLAB X IDE Power Budget Calculator to verify sleep-mode currents, which can drop below 1 uA with the PIC16 XLP modes and proper PMD peripheral gating.
Place the ICSP pins (RA0/RA1) on the PCB such that a 6-pin header or Tag-Connect pads are reachable for programming and debug. Route ICSPCLK and ICSPDAT as short, parallel traces with a ground guard to minimize noise pickup. Keep the MCLR pin (RA3) connected to a 10 kohm pull-up to VDD with a 100 nF decoupling capacitor to enable stable reset; an external supervisor IC is recommended for automotive applications.
Do not assume all PIC16F153xx 28-pin variants share the same pinout - the 15313 and 15323 are 8/14-pin variants with different pin functions. Verify each variant's pinout in the family datasheet before PCB reuse. Avoid driving large capacitive loads (>50 pF) directly on the oscillator pins (RA6/RA7); use a series resistor or buffer if needed. When using the internal HFINTOSC, allow at least 1 ms stabilization time after OSCFRQ change before relying on UART or PWM timing.
