PIC16F15324T-E/STVAO Overview
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory, data memory, and programmable I/O peripherals. Microcontrollers sit at the lowest tier of embedded compute - below microprocessors and SoCs - and are optimized for deterministic, low-power control of sensors, actuators, and communication buses in real-time products. The PIC16F153XX family specifically combines Core Independent Peripherals (CIPs) with eXtreme Low-Power (XLP) technology for battery-friendly designs.
Key features of the PIC16F15324T-E/STVAO include 7KB (4K x 14 words) of self-programmable Flash, 256 bytes of EEPROM, an active-high MCLR reset, an internal 32 MHz oscillator with PLL support, and a wide 2.3V to 5.5V supply range. The CWG peripheral simplifies complementary or dead-band PWM generation for half-bridge driver control, while the integrated 5-bit DAC and rail-to-rail op-amp option enable on-chip analog signal conditioning. Four 10-bit PWM channels support motor, LED, and switched-mode control loops without CPU intervention.
The device's XLP architecture delivers typical sleep currents below 50 nA with peripheral retention, making it well-suited for always-on, battery-powered sensor nodes. The integrated 10-bit ADC with automated channel scanning supports up to 11 analog inputs and pairs with the on-chip voltage reference for ratiometric measurements. The two EUSART modules can operate concurrently with the MSSP (SPI/I2C) peripheral, enabling simultaneous sensor and host connectivity.
Typical applications include IoT sensor nodes, low-power wireless remote controls, small appliance control boards, LED lighting drivers, HVAC damper control, and industrial sensor interface modules. The TSSOP-14 footprint suits space-constrained designs that still require multiple serial interfaces and analog channels. Engineering teams commonly pair this MCU with Microchip's MCP1700 LDO and sub-GHz transceivers such as the MRF89XA family.
When designing with this MCU, allocate the ICSP/ICD pins (RA0/RA1/RA2 plus VPP/MCLR) to dedicated programming access pads that remain accessible even after PCB assembly. Use the CWG in conjunction with the 10-bit PWM for switching power-converter control to offload timing-critical waveform generation from the CPU.

Typical Applications
PIC16F15324T-E/STVAO is suitable for 6 applications: IoT Sensor Node Controller, Appliance Control Board, LED Lighting Driver, HVAC Damper and Valve Controller, Industrial Sensor Interface Module, Low-Power Wireless Remote Control.
IoT Sensor Node Controller
The PIC16F15324T-E/STVAO is well-suited for battery-powered IoT sensor nodes due to its 32 MHz 8-bit PIC core, 7 KB Flash for protocol stacks, 512 bytes RAM for buffers, and XLP sleep currents under 50 nA. The four 10-bit PWM channels and CWG support dimming or actuator control, while 2 EUSART plus MSSP enable simultaneous sensor-bus (I2C SPI) and radio-link (UART) connectivity. Placed between an MCP1700 LDO and a sub-GHz transceiver, the MCU runs sensor read, ADC scan, and RF transmission sequences while sipping microwatts in sleep.
Recommended
Appliance Control Board
The PIC16F15324T-E/STVAO drives appliance control boards such as coffee makers, blenders, and washing-machine user interfaces, where its TSSOP-14 footprint fits into the main PCB and its 4 PWMs control motor, valve, and heater elements. The 10-bit ADC scans temperature and pressure sensors, while the integrated 5-bit DAC and hardware comparator implement closed-loop control without CPU intervention. Pair with a TRIAC driver and zero-cross detector for AC-line phase-angle dimming and motor-speed regulation.
Recommended
LED Lighting Driver
The PIC16F15324T-E/STVAO's four 10-bit PWMs and Complementary Waveform Generator (CWG) deliver precise dimming control for LED fixtures, supporting both constant-current and constant-voltage topologies. The CWG hardware offloads dead-band timing, ensuring complementary MOSFET switching without shoot-through in buck/boost LED driver stages. Sleep currents under 50 nA enable standby-mode fixture controls compliant with energy-saving regulations.
Recommended
HVAC Damper and Valve Controller
The PIC16F15324T-E/STVAO manages HVAC damper and valve actuators via its PWMs and comparator peripherals, interpreting thermostat setpoint signals and driving proportional motors. Its 10-bit ADC reads thermistor temperature sensors with adequate resolution for zone-level comfort control, while the 2 EUSARTs enable simultaneous Modbus or BACnet integration to a building automation network. Extended temperature grade (-40 C to +125 C) supports mechanical-room installations.
Recommended
Industrial Sensor Interface Module
The PIC16F15324T-E/STVAO functions as an industrial sensor interface front-end, digitizing 4-20 mA analog sensor signals with its 10-bit ADC and transmitting readings over RS-485 or Modbus RTU via its EUSART. The hardware comparator detects out-of-range alarms without CPU polling, and the CWG generates timing pulses for ultrasonic or capacitive sensor excitation. TSSOP-14 package fits in DIN-rail-mounted module housings.
Recommended
Low-Power Wireless Remote Control
The PIC16F15324T-E/STVAO powers coin-cell or AAA-battery remote controls with its XLP architecture delivering under-50 nA sleep currents, enabling multi-year battery life. Four PWMs drive RGB LED status indicators, while the 5-bit DAC and comparator implement infrared or sub-GHz modulation. The MSSP supports SPI peripherals for additional memory or display drivers, and the 2 EUSARTs handle protocol framing and debug output.

Key Differentiators
- Tape-and-reel packaging for automated assembly (vs PIC16F15324-E/STVAO)
- Full 7 KB Flash vs reduced Flash variants (vs PIC16F15323-E/ST)
- CWG and 5-bit DAC in TSSOP-14 (vs PIC16F15313-I/P)
Design Notes
Allocate ICSP/ICD pins (typically RA0/RA1/RA2/RA3/MCLR) to dedicated programming pads that remain accessible after PCB assembly. Failing to do so requires board rework for firmware updates. Use a 4-pin 0.1-inch header or castellated test pads.
The PIC16F15324T-E/STVAO's XLP sleep current is below 50 nA with peripherals gated, but rises to several microamps if the ADC, comparator, or PWM remain active. Configure unused peripherals to OFF in firmware before SLEEP, and use peripheral clock gating in the active state to minimize current draw in duty-cycled applications.
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor at the supply entry point. TSSOP-14 has limited thermal dissipation; route VDD and VSS traces on the top layer with short, wide paths to minimize voltage droop during switching events.
Compliance Information
