PIC16F723-I/SO - 8-Bit 20MHz Flash MCU | Microchip Technology
部品番号: PIC16F723-I/SO ✓ 生産中PIC16F723-I/SO 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory and peripheral functions onto one device. The PIC16F723 belongs to the PIC16 family hierarchy of 8-bit RISC microcontrollers, combining a mid-range CPU core with flash program memory and nanoWatt XLP technology. It provides a practical platform for embedded products that need local control, digital communication, analog measurement and low-power operation without relying on a separate processor and multiple supporting ICs.
Key features include 4K x 14 bits of flash program memory, a 20 MHz operating frequency and an 18 V to 55 V internal oscillator range as listed for this device. The family documentation identifies 35 single-word instructions, SPI and AUSART serial interfaces, two CCP modules and an 11-channel 8-bit ADC. These resources support motor control, signal conditioning, communications, sensing and general-purpose automation designs.
The PIC16F723-I/SO uses a Harvard-style PIC16 architecture with separate program and data-memory spaces and a compact instruction set. Flash memory permits in-circuit reprogramming, while the internal oscillator reduces the component count and board area required for clock generation. The 28-pin SOIC package provides enough I/O and peripheral connections for small control systems while remaining compatible with conventional surface-mount assembly methods.
Typical uses include low-cost sensor controllers, UART or SPI-based remote controls, compact power-conversion controllers, LED drivers, industrial acquisition modules and battery-powered equipment. The ADC supports analog measurement, while the CCP and timer resources can provide timing, capture, compare and PWM functions. An internal oscillator and XLP architecture are particularly useful when standby power consumption and board size matter.
Designers should preserve adequate decoupling close to the supply pins and follow the pin-assignment and grounding guidance in the manufacturer datasheet. Confirm the required clock configuration, peripheral pin multiplexing, ADC input limits and programming interface before layout release. The -I ordering code and -SO package suffix should be checked against temperature-range, package and production requirements during ordering.
This product page combines the manufacturer family information with practical guidance on low-power embedded design, peripheral allocation, PCB implementation and replacement selection. It also distinguishes exact temperature-grade options from broader PIC16 family relatives so that engineers can identify which substitutions preserve the 28-pin footprint and which require additional schematic verification.

主な用途
PIC16F723-I/SO の用途: 6 件s: Industrial Sensor and Signal Conditioning, UART and SPI Connected Control Module, Motor, Valve and PWM Control, LED Lighting and Display Controller, Battery-Powered Remote Control, Compact Power-Supply Controller.
Industrial Sensor and Signal Conditioning
The PIC16F723-I/SO fits compact sensor controllers because its 11-channel 8-bit ADC can acquire several analog inputs while the 20 MHz CPU supports signal conditioning and control logic. The 28-pin SOIC leaves access to timer, communications and digital I/O functions needed by industrial instrumentation. Its internal oscillator reduces external clock components, while nanoWatt XLP operation can reduce standby consumption in remotely powered equipment. Engineers should verify ADC input ranges, acquisition timing and analog grounding against the manufacturer data sheet before finalizing the front end.
おすすめ
UART and SPI Connected Control Module
PIC16F723-I/SO is appropriate for embedded modules that exchange commands or data through a wired serial link because the family provides both SPI and AUSART peripherals. Engineers can connect a sensor, transceiver or display without adding a separate communications controller, while timers and CCP modules support protocol timing and background control functions. The 28-pin SOIC also leaves enough pins for power, reset, programming and status signals. Firmware and PCB decisions should account for the particular pin multiplexing rules of the selected UART and SPI channels.
おすすめ
Motor, Valve and PWM Control
The two CCP modules and timer resources in PIC16F723-I/SO make it suitable for small motor, valve, pump and solenoid controllers that require PWM generation and precise timing. A 20 MHz CPU provides sufficient execution bandwidth for closed-loop control, input filtering and supervisory logic, while the flash-memory architecture permits field programming and firmware updates. For inductive or high-energy loads, keep the switching stage separate and use protection components appropriate to the actual current and voltage. The MCU should not drive load current directly unless the selected output pin limits are explicitly satisfied.
おすすめ
LED Lighting and Display Controller
PIC16F723-I/SO can coordinate LED dimming, status indicators and display sequencing through its timer, PWM and digital I/O resources. The 20 MHz operating speed supports responsive button handling, fade updates and communication with an external controller, while flash memory allows configurable lighting patterns to be stored directly in the MCU. Use current-limiting resistors or a constant-current driver as appropriate for the LED topology. For high LED counts, a serial expander reduces pin usage while preserving the low-power benefit of the internal oscillator.
おすすめ
Battery-Powered Remote Control
The internal oscillator and nanoWatt XLP capabilities of PIC16F723-I/SO are useful in battery-operated controls where minimizing board area and standby current are important. The MCU can sleep between user actions, wake through an interrupt and use SPI or AUSART for an accessory or host interface. Its flash program memory supports firmware revision and configurable control sequences without external EEPROM. Actual operating time depends on the selected sleep mode, oscillator configuration, communications duty cycle and leakage of the complete product rather than the controller alone.
おすすめ
Compact Power-Supply Controller
PIC16F723-I/SO is suitable for supervisory control in compact power-conversion equipment because its ADC, timers, CCP modules and flash memory allow autonomous regulation, monitoring and fault handling. A control loop can sample output voltage, adjust a converter through PWM and record operating status, while communication peripherals support supervisory reporting. The controller still requires appropriate voltage detection, isolation, gate-drive and protection circuitry determined by the power stage. Validate startup, fault response and component tolerances during hardware bring-up rather than relying only on the MCU firmware.

設計ノート
Route the power supply and ground connections directly to the appropriate PIC16F723-I/SO pins and place the manufacturer-recommended bypass capacitors immediately beside those pins. Keep analog inputs away from PWM outputs, oscillator nets and switching-node traces when the 8-bit ADC is used. A continuous ground plane beneath the device generally provides lower return impedance than a fragmented or split-plane arrangement.
Do not assume that matching SOIC packages guarantee a drop-in replacement. Check the 28-pin family pin-and-code compatibility chart, then verify every peripheral pin, programming interface, ADC input and power connection used by the design. The PIC16F723-E/SO is the closest ordering option identified, while broader PIC16 family alternatives may require firmware changes or different memory planning.
Select a power source with suitable headroom for the PIC16F723-I/SO and all connected peripherals. Decouple noisy loads so switching currents do not pass through the MCU's analog-ground return path. Use the manufacturer's electrical-characteristics table to set brownout, input-voltage and output-drive assumptions, and avoid driving external loads from a GPIO unless its absolute maximum and DC-current specifications support the actual load.
Reserve access to the programming pins and preserve the manufacturer's recommended clock-circuit layout. Because the internal oscillator can reduce external components, document the selected oscillator frequency and configuration in production files. If an external oscillator is added later, isolate the oscillator routing from ADC inputs and communication lines to prevent timing or measurement errors.
