PIC10F222-I/MC 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash or ROM), working memory (RAM), and peripheral interfaces (GPIO, ADC, timers) into one package. Microcontrollers in the PIC10 family occupy the ultra-small-footprint end of the market, targeting applications where PCB space and BOM cost dominate the design trade-off. The PIC10F222 specifically adds a 4 MHz internal oscillator option alongside the default 8 MHz oscillator, providing flexibility for low-power or timing-sensitive applications.
Key features include 4 I/O pins (3 bidirectional GP0/GP1/GP2 + 1 input-only GP3), one 8-bit timer (TMR0) with watchdog, an analog comparator, and an 8-bit ADC. The device operates from 2.0V to 5.5V supply voltage and consumes very low current, making it well-suited for battery-powered designs. The wide VDD range permits direct connection to 2-cell battery stacks as well as regulated 3.3V or 5V rails.
Architecturally, the PIC10F222 uses a Harvard RISC core with a 12-bit instruction word and 8-bit data path. Single-cycle instruction execution (1 microsecond at 4 MHz) delivers approximately 1 MIPS of throughput, an order of magnitude higher than 8-bit competitors in the same price tier. The in-circuit serial programming (ICSP) interface allows Flash reprogramming without removing the part from the board.
Typical applications include consumer remote controls, IR transmitter/receiver circuits, small appliance control, LED decorative lighting, battery-powered toys, and simple sensor signal conditioning. The 4 I/O pins limit use to highly cost-sensitive or space-constrained designs where a few GPIO plus ADC and timer suffice.
When designing with the PIC10F222-I/MC, allocate the 8-pin DFN footprint carefully because only 4 pins are usable as general-purpose I/O. Decouple VDD with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin, and ensure MCLR is tied to VDD through a 10 kohm resistor or driven externally for ICSP.

일반적인 애플리케이션
PIC10F222-I/MC 적합 용도: 7 애플리케이션s: Consumer Remote Control Transmitter, Battery-Powered Sensor Node, LED Decorative Lighting Controller, Small Appliance Control Board, Automotive Accessory LED Driver, Simple Toy and Hobby Electronics, Smart Home Edge Sensor.
Consumer Remote Control Transmitter
The PIC10F222-I/MC fits consumer IR remote controls because it integrates a 4/8 MHz internal oscillator, 8-bit ADC for battery-voltage sensing, and 4 GPIO pins in a 2x3 mm DFN - the smallest MCU footprint from Microchip. With 33 single-cycle instructions and 1 MIPS throughput, the device can bit-bang RC5, NEC, or SIRC IR protocols directly from software timers. The 2.0-5.5V VDD range accepts two AAA cells directly, eliminating a regulator.

Battery-Powered Sensor Node
For wireless or wired sensor nodes, the PIC10F222-I/MC's 2.0V minimum VDD lets it run directly from a single CR2032 coin cell (3.0V nominal) down to its 2.0V cutoff. The 4 MHz selectable oscillator halves active power versus the 8 MHz mode for duty-cycled sampling applications. The 8-bit ADC reads thermistor or photodiode sensors while 23 bytes RAM buffers instantaneous readings. Its DFN-8 footprint occupies just 6 mm squared of PCB.
추천
LED Decorative Lighting Controller
In decorative LED strings, the PIC10F222-I/MC drives multiple LEDs through Charlieplexing on its 4 GPIO pins, supporting up to 12 LEDs with software multiplexing. The internal 4/8 MHz oscillator eliminates external clock components, reducing BOM cost. The 768-byte Flash stores multi-pattern animation sequences while 23 bytes RAM handles the running pattern state. Wide 2.0-5.5V VDD accepts USB-powered 5V or battery 3V rails directly.
추천
Small Appliance Control Board
Small appliances like electric toothbrushes, kitchen timers, or personal care devices benefit from the PIC10F222-I/MC's compact 2x3 mm DFN package, integrated ADC for battery or sense-line monitoring, and 8 MHz core for responsive user-interface handling. The 768-byte Flash stores simple state machines; ICSP allows late-stage firmware updates during manufacturing. The industrial -40C to +85C temperature range covers most consumer-appliance environments.
추천
Automotive Accessory LED Driver
Although not AEC-Q100 qualified itself, the PIC10F222-I/MC is widely used in aftermarket automotive accessories (interior LED strips, puddle lights, courtesy lamps) where its 4 GPIO can drive MOSFETs to switch LED strings. The wide 2.0-5.5V VDD tolerates 12V battery systems after a simple LDO. The -40C to +85C industrial range covers cabin temperatures. For OEM automotive designs, AEC-Q100 qualified PIC16 equivalents should be selected.
추천
Simple Toy and Hobby Electronics
For hobby kits, educational toys, and low-cost electronic gadgets, the PIC10F222-I/MC delivers 8-bit RISC performance at sub-$1 pricing in volume. Its 4 GPIO, 8-bit ADC, and analog comparator support simple feedback loops such as line-following robots, light-seeking toys, or reaction-time games. The ICSP interface allows students to reprogram the device repeatedly on a breadboard using a PICkit 3 or PICkit 4 programmer.
추천
Smart Home Edge Sensor
In IoT edge sensors, the PIC10F222-I/MC functions as a low-cost pre-processor that wakes a main radio MCU only when its analog comparator detects a threshold crossing. The 2.0V minimum VDD allows operation from a single 1.5V cell with a boost converter or two 1.5V cells in series. The 8 MHz internal oscillator and minimal external component count keep total BOM under 50 cents, ideal for disposable or single-use sensors.

설계 노트
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 6) with a short trace to the VSS pin (pin 4). For battery applications drawing peak currents during ADC conversion, add a 1 uF to 10 uF bulk capacitor in parallel. The PIC10F222 has no internal POR delay beyond the 72 ms default, so external reset circuitry is unnecessary in most designs. Estimated: quiescent current in sleep mode is below 1 uA per Microchip datasheet 40001270F.
The 8-pin DFN package has an exposed thermal pad on the bottom that is electrically connected to VSS. Solder this pad to a VSS copper pour to provide mechanical strength and thermal dissipation. Keep the copper pour at least 2 mm squared to prevent PCB delamination during thermal cycling. Use NSMD (non-solder mask defined) pads with 0.2 mm solder mask expansion for reliable solder joint formation.
When using an external crystal or resonator, route OSC1 (pin 8) and OSC2 (pin 7) traces as short as possible (under 10 mm) and guard them with a VSS ground pour to reduce EMI susceptibility. Keep digital switching traces (GP0/GP1 used for ICSP or PWM) at least 3 mm away from the oscillator traces to avoid coupling noise into the clock signal. Place MCLR pull-up resistor within 5 mm of pin 1.
Do not exceed 5.5V on VDD or apply voltage to GP3 before VDD is stable (it shares the MCLR function and can cause unwanted resets). The PIC10F222 does NOT have a true open-drain output on GP0-GP2; all GPIO are push-pull CMOS, requiring external pull-down resistors if used as wired-OR signals. The ADC input multiplexor shares pins with digital GPIO - configure the corresponding TRIS bit to input mode before reading ADC.
규정 준수 정보
