PIC10LF322T-I/OT Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (flash or ROM), data memory (RAM), and peripheral interfaces (ADC, PWM, timers, communication ports) into one package. MCUs sit beneath microprocessors in the embedded computing hierarchy: microprocessors require external memory and peripherals, while MCUs embed everything needed for stand-alone control. The PIC10 family is Microchip's smallest 8-bit line, optimized for cost-sensitive and space-constrained designs where only a few I/O are required.
Key features include 35 single-word instructions, 200 ns instruction execution at 5V, 4 I/O pins, hardware I2C and SPI support, and NanoWatt XLP (eXtreme Low Power) technology for sleep currents down to sub-microampere levels. The SOT-23-6 footprint is the same as a small analog IC, allowing direct substitution of discrete analog control circuits with a programmable device on the same board area.
The architecture is a RISC-based Harvard design with a 14-bit instruction word and separate program/data buses, enabling deterministic single-cycle instruction execution (except branches). The mid-range 8-bit core delivers efficient code density through 35 instructions, while on-chip peripherals are mapped via SFRs and accessed through standard C or assembly toolchains (MPLAB X IDE).
Typical applications include battery-powered sensor nodes, wearable form-factor controllers, LED lighting color/effect control, simple fan or pump controllers, and consumer toys where the 4-bit/4-pin GPIO budget is sufficient. The LF (low-voltage) variant extends operation down to 1.8V, enabling direct connection to single-cell alkaline or NiMH battery stacks without a boost converter.
When designing with this part, verify that the 4 available I/O pins can satisfy all required digital interfaces, because the small package count is the primary constraint. Use MPLAB X IDE with the XC8 compiler and pick the LF variant only when sub-3V operation is needed, otherwise the standard PIC10F322 is more cost-effective at 2.5V-5.5V operation.

Typische Anwendungen
PIC10LF322T-I/OT ist geeignet für 6 Anwendungs: Battery-Powered Sensor Nodes, Wearable Form-Factor Controllers, LED Lighting Color and Effect Control, Simple Fan or Pump Speed Controller, Consumer Toy and Novelty Electronics, IoT Edge Device Wake-Up Co-Processor.
Battery-Powered Sensor Nodes
The PIC10LF322T-I/OT is well suited to single-cell battery sensor nodes due to its 1.8V minimum supply and NanoWatt XLP sleep currents below 1 microampere. Its 3-channel 8-bit ADC multiplexes onto 4 GPIO pins, allowing direct measurement of up to three sensors (temperature, light, voltage) without external ADC. With 896 bytes of flash, the device fits typical sensor-fusion firmware including I2C master routines and a state machine; the 16 MHz clock at 3.6V supports responsive wake-and-transmit cycles that maximize battery life between sleep intervals.
Empfohlen
Wearable Form-Factor Controllers
Wearables with strict PCB area budgets benefit from the PIC10LF322T-I/OT SOT-23-6 footprint, which matches a single small-signal transistor land pattern. The 1.8V-3.6V supply is compatible with single-cell Li-Ion and coin-cell chemistries without a boost converter. The 4 GPIO pins drive two PWM channels for haptic feedback or LED brightness while the remaining pins read a button input and a thermistor via the on-chip ADC, completing a full user-interface node in <30 mm squared.
Empfohlen
LED Lighting Color and Effect Control
The PIC10LF322T-I/OT's two PWM channels and 8-bit ADC are sufficient for direct drive of single-channel LED strips or basic RGB color mixing via external MOSFETs. The 16 MHz clock supports smooth 8-bit PWM fade transitions without visible stepping, while NanoWatt XLP standby current is critical for always-on indicator applications. The 896-byte flash budget supports MiniPIC-style color-cycle firmware plus UART-command interpretation for digital-RGB or smart-bulb applications.
Empfohlen
Simple Fan or Pump Speed Controller
Closed-loop fan and small pump control fits the PIC10LF322T-I/OT's peripheral set: one PWM channel drives the power MOSFET, one ADC channel reads tachometer feedback or temperature, and the remaining GPIO handles start/stop button and fault LED. The 64-byte RAM is sufficient for PID control loops with simple integer arithmetic, and the deterministic 200ns instruction execution at 16MHz keeps control loop latency under 50us. The industrial -40C to +85C operating range supports appliance and HVAC environments.
Empfohlen
Consumer Toy and Novelty Electronics
Cost-sensitive consumer toys rely on the PIC10LF322T-I/OT's <0.50 USD pricing at volume and sub-30mm squared PCB footprint to deliver interactive features within tight BOM cost targets. The 4 GPIO pins drive two motors via H-bridge, two buttons, or two LEDs plus a buzzer; the on-chip ADC reads analog sensors such as tilt switches or capacitive touch pads. Flash-resident firmware supports sound-effect sequencing and sleep-mode battery preservation for months of shelf life on alkaline cells.
Empfohlen
IoT Edge Device Wake-Up Co-Processor
In IoT edge designs where a higher-end MCU handles connectivity, the PIC10LF322T-I/OT acts as a sub-microampere wake-up co-processor that monitors sensors and toggles the main MCU's enable line. Its 1.8V minimum supply and XLP sleep current allow it to run from a coin cell for years while the main system is powered down. The I2C/SPI peripheral on two GPIO pins allows the host MCU to read ADC data on wake-up, and the small SOT-23-6 footprint places the co-processor adjacent to the sensor with no board-area penalty.

Wichtigste Unterscheidungsmerkmale
- Highest flash density in PIC10 family with 1.8V minimum supply (vs. PIC10LF320T-I/OT)
- Low-voltage 1.8V operation in same pinout as standard variant (vs. PIC10F322T-I/OT)
- Three ADC channels plus two PWM in 6-pin footprint (vs. PIC10F200T-E/OT)
Designhinweise
The PIC10LF322T-I/OT draws sub-microampere current in Sleep mode thanks to NanoWatt XLP technology, but typical Run current at 16 MHz and 3.6 V is around 1 mA. For battery-powered designs, use the LF variant only when sub-3 V operation is required; otherwise the standard PIC10F322 offers better robustness at higher voltages. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 2.
GP3 is the only pin that cannot be configured as a digital output - it is MCLR/VPP by default. If a true general-purpose I/O is needed on this pin, the MCLRE configuration bit must be cleared in the configuration word, which disables external reset and relies on internal POR/BOR. Plan pin allocation carefully: GP0-GP2 are full-function GPIO, GP3 is input-only or reset.
Do not omit the ICSP programming connector or test points on prototype boards - the SOT-23-6 package has no debug header. Production programmers such as PICkit 3/4 or MPLAB Snap connect to VPP, VDD, VSS, ICSPCLK (GP1), and ICSPDAT (GP0). Leave these signals accessible in the layout to allow field firmware updates and factory calibration.
