PIC10LF320T-I/MC 概要
An 8-bit PIC microcontroller is a compact, low-power RISC-based processor widely used in embedded systems for simple control tasks. The PIC10F family belongs to Microchip's 8-bit MCU portfolio, which sits under the broader microcontroller hierarchy: microcontroller -> embedded processor -> semiconductor IC. These devices are favored for their deterministic instruction execution, ultra-low sleep currents, and minimal external component count, making them ideal for cost- and space-constrained applications.
Key features of the PIC10LF320T-I/MC include 4 I/O pins, an 8-bit ADC with multiple channel options, and support for in-circuit serial programming (ICSP). The integrated CLC, NCO, and CWG peripherals enable the generation of custom waveforms and logic functions without external components, reducing BOM cost and PCB area. The temperature indicator provides an on-chip analog temperature sensor for system monitoring.
The device leverages Microchip's enhanced mid-range 8-bit core, which delivers up to 16 MHz operation (8 MIPS) from a single-cycle instruction pipeline. Its nanoWatt XLP technology provides sleep currents in the nanoampere range, making it well-suited for battery-powered applications. The 8-bit ADC operates from the device supply and supports multiple acquisition modes for sensor interfacing.
Typical applications include consumer electronics remote controls, IoT sensor nodes, battery management accessories, LED lighting controllers, and small appliance controls. Its tiny 8-DFN footprint also fits wearables and space-constrained PCB modules. For cost-sensitive designs requiring minimal MCU capability, the PIC10LF320T-I/MC provides a balance of integration and low power consumption.
When designing with this part, note that only 4 I/O pins are available; complex peripherals (UART, I2C, SPI) are not natively present but can be implemented in firmware using the CLC/NCO peripherals. Decoupling capacitors (typically 100 nF) should be placed close to VDD, and unused I/O pins should be configured as outputs low to minimize power consumption.

主な用途
PIC10LF320T-I/MC の用途: 6 件s: Consumer Remote Control MCU, Battery-Powered IoT Sensor Node, LED Lighting Controller, Personal Electronics Wearable, Small Appliance Control, Capacitive Touch Interface Module.
Consumer Remote Control MCU
The PIC10LF320T-I/MC fits remote control designs requiring minimal MCU capability in an ultra-small footprint. Its 4 I/O pins can drive IR LEDs via PWM and read a small keypad matrix, while 448 bytes of Flash comfortably holds simple IR protocol stacks (RC5, NEC, Sony SIRC). The 1.8V-3.6V range supports direct coin-cell operation with no boost converter, and nanoWatt XLP sleep currents extend battery life to multiple years of standby.
おすすめ
Battery-Powered IoT Sensor Node
For IoT edge nodes that wake periodically to read sensors, the PIC10LF320T-I/MC's nanoWatt XLP sleep current (sub-microampere) and integrated 8-bit ADC make it a strong fit. Its 1.8V minimum supply allows operation from partially-depleted coin cells, maximizing battery utilization. The CLC and NCO peripherals can generate custom timing patterns for one-wire or simple proprietary RF protocols without burdening the CPU. The 8-DFN package occupies only 6 mm², fitting in the smallest sensor packages.
おすすめ
LED Lighting Controller
LED strip and accent lighting benefit from the PIC10LF320T-I/MC's integrated PWM, CWG (Complementary Waveform Generator), and NCO peripherals. The CWG can drive complementary MOSFET outputs for synchronous buck LED drivers without external timing ICs. With 4 I/O pins, the device can control one or two LED channels while accepting a button input for dimming or color selection. Its 16 MHz instruction rate supports smooth PWM dimming without visible flicker.
おすすめ
Personal Electronics Wearable
Wearable devices such as fitness bands, smart rings, and hearables demand the smallest possible MCU footprint. The PIC10LF320T-I/MC's 8-DFN 2x3 mm package (6 mm²) is among the smallest 8-bit MCU options, freeing PCB area for sensors and batteries. Its 32-byte RAM and 448-byte Flash support simple activity classification firmware or button-press detection. Sleep currents under 1 microampere preserve multi-day battery life for always-on wearables.
おすすめ
Small Appliance Control
Small appliances (electric toothbrushes, handheld fans, kitchen timers) typically require 1-3 I/O lines and minimal firmware for timing/motor control. The PIC10LF320T-I/MC's 4 I/O pins and 16 MHz speed accommodate simple BLDC commutation via the CWG and NCO peripherals, while PWM drives motor FETs directly. Its 1.8V-3.6V range supports 2xAA/AAA battery packs, eliminating boost converters. The integrated temperature indicator enables thermal protection for motor-driven appliances.
おすすめ
Capacitive Touch Interface Module
The PIC10LF320T-I/MC's 4 I/O pins can each function as a capacitive touch sensor using Microchip's mTouch sensing firmware libraries, supporting simple 4-button user interfaces. The CLC peripheral handles touch acquisition timing autonomously, freeing the core for filtering and decision logic. Its 8-DFN package fits behind small touch panels in consumer products, and the low-voltage operation supports direct battery power. The 16 MHz throughput handles debouncing and gesture recognition in real time.

設計ノート
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 6) and VSS (pin 5) to suppress high-frequency noise during core switching. Estimated: at 16 MHz operation, instantaneous current transients can reach 10-15 mA peaks; without local decoupling, these cause voltage dips that may corrupt ADC conversions. For battery applications, add a 10 uF bulk capacitor near the supply input to handle inrush during wake-up from sleep.
The 8-DFN package has an exposed thermal pad beneath the part that must be soldered to a copper pad on the PCB for mechanical reliability and thermal dissipation. Although the MCU consumes minimal power, the pad improves solder joint strength during thermal cycling. Use NSMD (non-solder mask defined) pads with multiple thermal vias to the inner ground plane for best solderability and heat spreading in reflow assembly.
Pins RA0 (ICSPDAT) and RA1 (ICSPCLK) are shared with the in-circuit serial programming interface. If these pins are used for general I/O, ensure that the programming tool can still drive them during ICSP. A common mistake is connecting a low-impedance load (such as an LED without a series resistor) to RA0/RA1, which prevents ICSP communication. Always provision a way to isolate these loads during programming or use RA2/RA4/RA5 for output functions.
Keep digital signal traces away from the analog ADC input pins to minimize coupled noise. The 8-bit ADC has limited resolution (256 steps), so each LSB represents about 4.7 mV at a 1.2V reference. Estimated: cross-talk from adjacent switching signals can introduce 5-10 LSB errors. Route the ADC reference (VDD) separately from noisy digital supplies when possible, and use a small RC filter (1 kohm + 100 nF) on the analog input for sensor signal conditioning.
