PIC10F320T-E/OT Overview
An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating a CPU core, program memory, RAM, peripherals, and I/O. MCUs sit at the bottom of the embedded computing hierarchy, above discrete logic but below microprocessors and SoCs. The PIC10F32X family uses Microchip's enhanced mid-range 8-bit core, which delivers deterministic single-cycle instruction execution (other than branches) and low-power sleep modes optimized for battery-powered edge applications.
Key features of the PIC10F320T-E/OT include an integrated 8-bit Analog-to-Digital Converter (ADC) with up to 4 channels, 6-bit PWM generation, a Configurable Logic Cell (CLC), Numerically Controlled Oscillator (NCO), Complementary Waveform Generator (CWG), and an on-chip temperature indicator. The supply voltage range of 2.3V to 5.5V and 4 I/O pins make this MCU ideally suited for space-constrained designs that need more than a simple timer IC but cannot accommodate larger QFP or QFN packages.
The PIC10F320T-E/OT uses the 6-pin SOT-23-6 package, which provides a compact 2.9 mm x 1.6 mm footprint - roughly one-tenth the board area of an SOIC-8. Internal peripherals (CLC, NCO, CWG) emulate discrete analog functions in firmware, reducing external component count and BOM cost. The enhanced mid-range core executes most instructions in a single clock cycle, simplifying real-time control tasks.
Typical applications include consumer appliance control, LED drivers, battery chargers, sensor signal conditioning, simple motor control, and IoT edge nodes. The integrated ADC and PWM allow direct interfacing with analog sensors and small actuators without additional ICs.
When designing with this part, use Microchip's MPLAB X IDE with the XC8 compiler and PICkit 4 or Snap programmer. Ensure decoupling capacitor placement is within 5 mm of the VDD pin, and verify that the GP3 input-only pin limitation is accounted for in I/O mapping.

Typical Applications
PIC10F320T-E/OT is suitable for 7 applications: Battery-Powered Sensor Node, LED Indicator and Driver Control, Simple Closed-Loop Fan or Blower Speed Control, Consumer Appliance User Interface, Toy and Hobby Electronics, IoT Edge Sensor Conditioning, Smart Home Wireless Remote Control.
Battery-Powered Sensor Node
The PIC10F320T-E/OT fits battery-powered sensor nodes because its 2.3V to 5.5V supply range covers two-cell alkaline and single-cell Li chemistries, while the 4 I/O pins and integrated 8-bit ADC connect directly to thermistor, photocell, or moisture sensors. Its CLC and NCO peripherals generate accurate timing references in firmware without external oscillators, reducing sleep current to single-digit microamps. Compared with discrete timer-IC solutions, the PIC10F320T-E/OT adds programmable threshold logic and a temperature indicator that calibrates the ADC against die temperature, eliminating the need for a separate temperature compensation circuit.
Recommended
LED Indicator and Driver Control
The PIC10F320T-E/OT suits compact LED indicator and driver control applications because its 6-bit PWM and Complementary Waveform Generator (CWG) drive small LEDs and FETs directly from the GP pins, eliminating external PWM controllers. The 16 MHz enhanced mid-range core supports smooth dimming transitions in firmware while the temperature indicator protects LEDs from thermal runaway by reducing PWM duty cycle when die temperature rises above setpoint. SOT-23-6 packaging lets the MCU fit behind a 3 mm LED on the PCB, supporting edge-lit appliance front panels and status indicator designs.
Recommended
Simple Closed-Loop Fan or Blower Speed Control
For simple closed-loop fan or blower speed control, the PIC10F320T-E/OT's ADC reads tachometer feedback while the CWG generates complementary PWM signals to drive a small brushless DC motor's gate driver. The NCO produces fractional-N frequencies for stable RPM setpoints, and the 16 MHz instruction throughput delivers sub-millisecond loop response without external op-amps. The 2.3V to 5.5V range supports 5V USB-powered fans and 3.3V low-voltage designs alike, making the PIC10F320T-E/OT a fit for compact thermal management modules.
Recommended
Consumer Appliance User Interface
The PIC10F320T-E/OT handles consumer appliance user-interface tasks such as capacitive touch button scanning, LED status feedback, and buzzer drive because its CLC peripheral implements the touch sensing oscillator in hardware while the PWM modulates the buzzer tone. The 4 I/O pins map directly to two capacitive buttons, one status LED, and one piezo buzzer - a complete UI in one SOT-23-6 part. The -40C to +125C extended operating temperature range supports kitchen and laundry appliances where ambient temperatures routinely exceed 70C near heating elements.
Recommended
Toy and Hobby Electronics
In toy and hobby electronics, the PIC10F320T-E/OT drives small motors, sound effects, and RGB LEDs because its CWG generates dual complementary PWM channels for H-bridge motor control and its NCO synthesizes audio frequencies without external DACs. The 448 bytes of Flash holds animation sequences and sound bytes for simple interactive toys, while the SOT-23-6 package fits inside credit-card-sized enclosures. The 2.3V to 5.5V supply range supports two-cell alkaline, single-cell Li-ion, and USB-powered designs across the full toy product line.
Recommended
IoT Edge Sensor Conditioning
For IoT edge sensor conditioning nodes, the PIC10F320T-E/OT performs local analog preprocessing before forwarding to a higher-tier MCU over UART or I2C because its 8-bit ADC samples at typical rates up to 100 ksps and its CLC generates window-comparator interrupts in hardware. The temperature indicator calibrates sensor offset against die temperature, improving measurement accuracy without external references. At full power, the PIC10F320T-E/OT draws sub-milliamp current; in sleep mode it drops to the device's low-power Idle and Sleep states, suiting battery-powered IoT nodes that wake periodically for measurements.
Recommended
Smart Home Wireless Remote Control
The PIC10F320T-E/OT powers smart home wireless remote control transmitters because its GP pins connect directly to pushbuttons and a sub-GHz or 2.4 GHz radio module over SPI or UART, with the CLC encoding button-press patterns into wake-up interrupts. The NCO generates accurate RF carrier references in firmware without external crystals, reducing BOM cost for high-volume remote SKUs. The 2.3V to 5.5V supply supports both 3V coin-cell remotes and 5V USB-charged designs, while the SOT-23-6 footprint fits inside ultra-thin remote enclosures.

Design Notes
Place the VDD bypass capacitor within 5 mm of pin 1 (VDD) on the SOT-23-6 package. A 0.1 uF X7R ceramic is sufficient for most applications; add a 1 uF bulk cap if the supply line impedance is high. For ADC accuracy, keep the AGND path short and avoid routing noisy digital signals beneath the VDD trace.
GP3 is input-only on the PIC10F320T-E/OT and cannot drive a logic-high output - it lacks an internal weak pull-up as a digital output. If your design requires a fourth output, use the CLC peripheral to synthesize a PWM or logic output on GP3, or reassign GP0-GP2 as outputs and use GP3 only as a digital input or MCLR.
The PIC10F320T-E/OT's ADC uses VDD as its reference voltage, so any noise or ripple on VDD directly couples into ADC readings. For precision measurements above 8 LSBs, add an external 10 uF decoupling capacitor near VDD and avoid switching loads (PWM-driven LEDs or motors) on the same supply rail during ADC sampling. The on-chip temperature indicator can be used to compensate ADC offset against die temperature in firmware.
The SOT-23-6 package has a thermal resistance of approximately 200 C/W (theta_JA) on a standard JEDEC 4-layer test board. At the device's typical 1 mA active current and 5V supply, internal dissipation is only 5 mW, so junction temperature rise is negligible. For high-temperature ambient environments above 85C, the -E extended-temperature grade (-40C to +125C) is required - the -I grade (industrial, -40C to +85C) will not survive.
Compliance Information
RoHS and lead-free compliant per Microchip product page. Halogen-free per Microchip PIC10F family datasheet. AEC-Q100 not qualified - this part is not automotive-grade despite the extended -E temperature range.
