PIC10F320-I/MC 개요
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and integrated peripherals such as timers, ADC, and communication interfaces. The PIC10F320 belongs to the 8-bit PIC10F family, which sits below 16-bit PIC24 and dsPIC devices and above simple logic ICs in the embedded hierarchy. Within the PIC10F family, the PIC10F32x sub-family represents the next generation of enhanced mid-range 8-bit cores with integrated analog peripherals, addressing space-constrained designs that need more than a simple timer but cannot afford a larger package.
Key differentiating features include the enhanced mid-range 16-bit instruction set with 49 instructions, 16 MHz internal oscillator accuracy of +/- 2 percent over the full -40C to +85C industrial range, an on-chip 8 MHz high-speed oscillator with 4x PLL option, and a single-pin ICSP debug interface. The 10-bit ADC delivers up to 25 ksps with hardware acquisition timer, while the PWM module supports edge- or center-aligned operation with independent period and duty cycle. The integrated comparator has programmable reference and can wake the device from sleep, enabling ultra-low-power battery monitoring applications.
Typical applications include LED lighting control, fan speed control, simple sensor interfaces, battery chargers, and consumer appliance primary controllers. The combination of internal oscillator, internal voltage reference, and 4 I/O pins allows a complete controller design with no external components beyond a decoupling capacitor and optional pull-up. Designers migrating from PIC10F200/PIC10F202 gain an integrated ADC, PWM, and EEPROM, eliminating the need for an external analog front-end in cost-sensitive designs.
Designers should note that the -I suffix indicates the -40C to +85C industrial temperature range and the /MC suffix designates the 8-pin DFN (2x3 mm) package, which has no leads on the edges and requires careful PCB land pattern design for reliable reflow soldering. Programming is supported via the ICSP interface using Microchip MPLAB X IDE and PICkit programmers.

일반적인 애플리케이션

LED Lighting Controllers
The PIC10F320-I/MC is well-suited for compact LED lighting controllers and decorative light drivers, leveraging its 16-bit PWM module, 16 MHz core, and 8-bit ADC. In a typical 4-channel LED driver design, the MCU generates high-resolution PWM at up to 20 kHz to avoid audible flicker while the ADC samples a photodiode or potentiometer for closed-loop brightness control. The internal 16 MHz HFINTOSC eliminates the need for an external crystal, allowing a complete controller PCB under 10 x 10 mm. The 4.17 mA typical operating current at 4 MHz and sub-microamp sleep current make the part ideal for battery-powered accent lighting where the MCU spends most of its time in sleep between PWM updates.

Battery-Powered Sensor Nodes
The PIC10F320-I/MC fits ultra-compact battery-powered sensor nodes where PCB area and quiescent current are critical. The on-chip 8-bit ADC reads a thermistor or battery voltage divider while the integrated comparator wakes the MCU from sleep when a threshold is crossed, eliminating continuous CPU polling. At 2.3V minimum supply, the MCU operates directly from a single CR2032 coin cell or two-cell alkaline stack. The 8-DFN (2x3 mm) package keeps the entire controller under 6 mm squared of board area. Estimated battery life for a 1 percent duty-cycle wake-and-measure cycle exceeds 5 years from a 220 mAh CR2032.
추천
Fan and Motor Speed Control
The PIC10F320-I/MC drives small brushed DC fans and low-power motors through a single MOSFET, using its 16-bit PWM to regulate speed and the ADC to read back tachometer or back-EMF signals. The enhanced mid-range core executes a closed-loop PI controller at 16 MHz with sub-100 microsecond loop time, while the 32-byte EEPROM stores calibration constants and trim values across power cycles. Operating temperature of -40C to +85C supports automotive interior and industrial cabinet fans. The internal HFINTOSC keeps BOM cost minimal: only a decoupling cap and gate resistor are needed beyond the MCU and FET.
추천
Consumer Appliance Primary Controller
The PIC10F320-I/MC serves as a primary user-interface controller in small consumer appliances such as coffee makers, blenders, and personal care devices, where its 4 GPIO drive buttons, LEDs, and a single low-side triac or relay. The internal comparator detects zero-cross events for triac dimming, while the PWM generates buzzer tones for audio feedback. At a unit cost under $0.50 in volume, the MCU enables feature differentiation in price-sensitive products. The 8-DFN package and 16 MHz internal oscillator eliminate external clock and timing components.
추천
Capacitive Touch Button Replacement
The PIC10F320-I/MC implements a 1- to 4-button capacitive touch interface using the on-chip comparator and a single ADC channel per pad. The mTouch firmware library from Microchip supports wake-on-touch from sleep mode, with average current under 5 microamps for battery-powered remote controls and IoT end-nodes. The 16-bit PWM modulates LED brightness feedback behind each touch pad. The 8-DFN (2x3 mm) footprint fits behind a 5 x 5 mm touch sensor pad array, allowing a complete touch UI on a flex PCB or rigid sub-module.
추천
Industrial Sensor Signal Conditioning
The PIC10F320-I/MC operates as a low-cost front-end for industrial sensors requiring on-board linearization, scaling, or alarm thresholding. The 8-bit ADC digitizes a 4-20 mA loop or 0-10V transducer output while the comparator triggers an alarm output when the input crosses a programmed limit. The 32-byte EEPROM retains calibration coefficients across power cycles. Industrial -40C to +85C operation supports factory-floor installations, and the small DFN package fits inside sensor housings. UART/I2C via bit-banged firmware allows reporting to a host PLC or local display.

설계 노트
The 8-DFN (2x3 mm) package has no gull-wing leads and instead uses perimeter metallization. Apply a land pattern following IPC-7351 with NSMD pads slightly larger than the package pads (approximately 0.5 mm pitch, 0.3 mm pad width). Expose the central thermal pad to a copper pour with at least 4 thermal vias (0.3 mm drill) to the internal ground plane for heat spreading. Reflow profile should follow JEDEC J-STD-020 MSL-1 conditions (peak 260 C) since the device is rated moisture sensitivity level 1.
Place a 100 nF X7R decoupling capacitor within 3 mm of the VDD pin (pin 5) with the trace to VDD being shorter than the trace to VSS. For designs switching PWM outputs above 10 kHz, add a 10 uF bulk capacitor near the IC. The PIC10F320 internal 16 MHz HFINTOSC startup time is approximately 1 microsecond; allow adequate VDD rise time (< 50 microseconds) for clean oscillator start. Power-on reset (POR) is released after VDD exceeds 1.5V with a 60-microsecond typical delay.
Estimated: At 16 MHz and 5V, the PIC10F320 draws approximately 4.5 mA active current. Designers migrating from PIC10F200 must remove the 4 MHz/8 MHz clock-divider configuration code since PIC10F320 uses the enhanced mid-range core with 49 instructions vs the baseline 33-instruction set. The MCLR pin (RA3/MCLR/VPP) is input-only and cannot be configured as a digital output; route it as MCLR with a 10 kohm pull-up to VDD for normal operation, or as ICSP VPP for in-circuit programming.
When using the ADC, add a 100 nF bypass on the VDD pin and a small RC filter (1 kohm + 100 nF) on the analog input to limit source impedance below the ADC's 10 kohm recommended maximum. Acquisition time should be programmed to at least 8 microseconds for full 8-bit accuracy. For PWM-driven inductive loads, add a 100 ohm series gate resistor and a flyback diode to protect the MCU pin from kickback voltages exceeding the absolute-maximum rating of -0.3V to VDD + 0.3V.
