PIC10F220-I/P 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash/ROM), volatile data memory (RAM), and peripherals such as timers, ADC, communication interfaces, and GPIO onto one die. Microcontrollers sit at the bottom of the embedded compute hierarchy: microcontroller -> embedded processor -> microprocessor -> CPU, and within the 8-bit MCU category they include subfamilies such as PIC10, PIC12, PIC16, PIC18, and ATtiny/ATmega. The PIC10F220 belongs to the PIC10F 6-pin/8-pin ultra-small-footprint family, optimized for analog-intensive, cost-driven applications where every GPIO and PCB square millimeter matters.
Key features of the PIC10F220-I/P include an integrated 6-bit analog-to-digital converter (ADC), one 8-bit timer (TMR0), a watchdog timer with on-chip RC oscillator, power-on reset, in-circuit serial programming (ICSP), and an internal 4 MHz / 8 MHz oscillator that eliminates the need for an external crystal. The device supports a wide operating voltage range from 2.0V to 5.5V, making it compatible with both 3.3V and 5V rails common in consumer and industrial systems.
The 12-bit-wide instruction set is highly symmetrical, producing a typical 2:1 code compression compared with other 8-bit microcontrollers in its class, so application code fits in less Flash and requires fewer fetches. Combined with Harvard-style separate program and data buses, the device delivers deterministic single-cycle execution on most instructions, which simplifies real-time control loops.
Typical applications include appliance controls, LED driving, battery chargers, toys, simple sensor signal conditioning, and any cost-sensitive embedded system that needs an 8-bit brain in an 8-pin footprint. Engineers also deploy the PIC10F220 in auxiliary housekeeping roles where it acts as a power-sequence supervisor or PWM controller for a larger SoC.
When designing with this part, note that the 8-pin PDIP package makes hand-prototyping and breadboard-friendly rework easy. The device shares its instruction set with the broader PIC10/12/16 family, so code written for the PIC10F220 ports to larger PICs with minimal modification, and the ICSP interface allows firmware updates without removing the chip from the board.

主な用途
PIC10F220-I/P の用途: 6 件s: Battery Charger Control, Appliance and White-Goods Control, Toy and Hobby Electronics, LED Lighting and Dimming, Sensor Signal Conditioning, Power-Supply Housekeeping Supervisor.
Battery Charger Control
The PIC10F220-I/P fits low-end battery charger controllers because its 6-bit ADC is sufficient to read battery voltage in 39 mV steps at a 5 V reference (5 V / 64), and its 2.0–5.5 V supply range covers single-cell Li-ion and multi-cell NiMH packs directly. The 8 MHz core executes a CC/CV charge algorithm in 1 µs per instruction, leaving ample headroom for PWM generation on GP2 while monitoring VDIV on AN0 via the on-chip ADC. Compared with a pure analog charger, the PIC10F220 adds programmable termination thresholds and battery-health telemetry at under $0.50 in volume.
おすすめ
Appliance and White-Goods Control
In cost-sensitive appliance subsystems such as coffee makers, blenders, and air purifiers, the PIC10F220-I/P provides the minimum viable MCU: 4 GPIO for keypad/LED I/O, internal oscillator to avoid a $0.05 crystal, and the brown-out reset that prevents latch-up during brown-outs from the AC mains. The 384-byte Flash holds simple state machines for wash-cycle, brew-cycle, or fan-speed control, while the 6-bit ADC reads a potentiometer or thermistor for user input. Industrial temperature range (-40 to +85 °C) covers under-cabinet and behind-panel deployments.
おすすめ
Toy and Hobby Electronics
The PIC10F220-I/P is widely used in sub-$10 toys, LED blinkers, and hobby kits because its 8-pin PDIP is breadboard-friendly and Microchip's MPLAB XC8 toolchain offers a free license tier for the PIC10 family. The internal 8 MHz oscillator keeps BOM count to one chip plus passives, while the 4 GPIO pins drive 2–4 LEDs with PWM via the TMR0 overflow interrupt. The 6-bit ADC reads IR receiver or LDR sensor signals for line-following robots and light-up wearables with under 50 lines of C code.
おすすめ
LED Lighting and Dimming
The PIC10F220-I/P controls single-LED or multi-LED strings in decorative lighting, signage, and indicator modules where its 4 GPIO can drive MOSFETs directly through the internal weak pull-ups, and the TMR0 generates PWM dimming at frequencies above 100 Hz to avoid flicker. The 6-bit ADC accepts a 0–5 V analog dimming input from a potentiometer or a 0–10 V lighting control signal, while the wide 2.0–5.5 V supply range accommodates both USB-powered and 24 V bus-powered fixtures after a small LDO. The 384-byte Flash easily holds a logarithmic dimming curve.
おすすめ
Sensor Signal Conditioning
The PIC10F220-I/P acts as a smart front-end for analog sensors such as thermistors, photocells, and gas-sense resistors, where its 6-bit ADC quantizes the sensor bridge, and the core applies linearization, thresholding, or alarm logic before signalling the host MCU via a single GPIO. Brown-out reset and watchdog timer guarantee the conditioning block recovers from voltage transients on long sensor cables in industrial plants. Operating from 2.0 V extends battery life in wireless sensor nodes by 30–50% versus 3.3 V-only MCUs.
おすすめ
Power-Supply Housekeeping Supervisor
Beyond discrete supervisor ICs, the PIC10F220-I/P serves as a programmable housekeeping MCU in multi-rail power supplies, sequencing enable signals, monitoring rail voltages with the 6-bit ADC, and asserting PG (power-good) or RESET to the main SoC. Its 1 µs instruction cycle allows sequencing delays from 1 µs to several seconds by adjusting the TMR0 prescaler, and the internal oscillator eliminates the need for an external timing reference. Compared with a dedicated supervisor IC, this approach adds configurable thresholds and fault logging at marginal cost increase.

設計ノート
The PIC10F220-I/P operates from 2.0 V to 5.5 V and consumes approximately 1 mA active at 8 MHz / 5 V. Place a 0.1 µF ceramic decoupling capacitor as close as possible between VDD (pin 8) and VSS (pin 6) to suppress switching noise during GPIO transitions; an additional 10 µF bulk capacitor is recommended if the supply traces exceed 25 mm. The brown-out reset circuit holds the core in reset until VDD rises above the BOR threshold (~2.0 V), eliminating the need for an external reset IC in most cost-sensitive designs.
When laying out the 8-pin PDIP footprint, route the ICSP lines (ICSPDAT on pin 1, ICSPCLK on pin 2) with short traces to a 6-pin header placed at the board edge, keeping the traces below 50 mm to avoid programming failures. Connect the MCLR/VPP pin (pin 4) directly to VDD through a 10 kΩ pull-up resistor; do not place a capacitor on MCLR unless you intentionally slow the rise time for in-circuit programming sequencing. Keep analog inputs AN0/AN1 short and away from switching signals to preserve 6-bit ADC integrity.
Estimated: GP3 on the PIC10F220-I/P is input-only — do not configure it as an output in firmware, or the pin will not drive high. The 6-bit ADC on the PIC10F220 is shared with the comparator module on the PIC10F206, so the same source code compiled for a PIC10F220 will not run unchanged on a PIC10F206 even though the pinout matches. When migrating to PIC10F200 to save cost, verify that no firmware path reads the ADC result register ADRES; the register does not exist on the PIC10F200 and the read returns undefined values.
The internal 8 MHz oscillator of the PIC10F220-I/P is factory-calibrated to ±1% at 25 °C / 5 V but drifts up to ±5% across the full -40 °C to +85 °C industrial range. For UART bit-banged applications that demand tighter baud-rate accuracy, either calibrate the OSCTUNE register in firmware at production or use a 4 MHz operating mode where drift is roughly halved. Keep the device away from heat sources (>50 mm) on the PCB to minimize temperature-induced oscillator drift in time-sensitive designs.
