PIC16F723A-E/SO 概要
A PIC microcontroller is a compact, deterministic 8-bit processor built on Microchip's RISC (Reduced Instruction Set Computer) architecture. PIC16F MCUs combine a Harvard-bus CPU with integrated Flash, RAM, EEPROM and rich peripherals into a single chip, sitting at the entry tier of the 8-bit MCU hierarchy: PIC10/12/16/18 -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. XLP parts add aggressive sleep currents and peripheral gating for battery applications.
Key features include up to 20MHz operation, 7KB Flash (4096 x 14-bit words), 192 bytes RAM, 256 bytes EEPROM, multiple communication peripherals (EUSART, MSSP I2C/SPI), 11-bit ADC, comparators, timers, nanoWatt XLP sleep modes below 1uA, and an extended (-40C to +125C) operating range (the -E suffix). It targets automotive-grade and industrial applications requiring AEC-Q100-style robustness in the SOIC-28 form factor.
Architecturally, the PIC16F723A uses an enhanced mid-range 16-bit instruction word with 35 single-word instructions, most executing in one instruction cycle, plus a hardware multiplier, shadow register set, and peripheral pin select for flexible signal routing without PCB rework. The die integrates the ADC and analog comparators alongside the digital core, enabling single-chip sensor interfaces with no external components beyond passives.
Typical applications include automotive body modules, sensor interfaces, low-power IoT nodes, consumer appliance controls, and industrial sensor hubs. The wide SOIC-28 footprint supports hand-solderable prototypes and high-reliability manufacturing flows, while XLP enables multi-year battery life in remote-sensor applications such as utility meters and wireless thermostats.
When designing with this part, ensure the in-circuit serial programming (ICSP) lines are accessible in production, configure the configuration bits for oscillator selection, and route the analog supply (AVDD) appropriately when using the ADC, since ADC accuracy is sensitive to supply decoupling and ground bounce on a mixed-signal PCB.

主な用途
PIC16F723A-E/SO の用途: 6 件s: Automotive Body Electronics, Battery-Powered IoT Sensor Nodes, Industrial Sensor Hubs, Consumer Appliance Controls, Medical Health-Monitoring Devices, LED Lighting and Smart Controls.
Automotive Body Electronics
The PIC16F723A-E/SO fits body-electronics modules because its -40C to +125C extended-temperature grade and AEC-Q100-style qualification handle under-hood and cabin environment stress. The 7KB Flash, 192 bytes RAM, and 11-bit ADC enable reliable reading of switches, sensors (temperature, humidity, door state) and small PWM-driven actuators. With nanoWatt XLP drawing <1uA in sleep, body modules can sit in key-off state for weeks without draining the battery. Place the SOIC-28 wide-body near connector pin headers for clean signal routing to analog and digital sensors; the EUSART links to CAN/LIN transceivers (e.g., MCP2515 for CAN, MCP2003 for LIN) for in-vehicle networking. Verify EMC decoupling at the AVDD pin when ADC channels drive current-shunt monitoring.

Battery-Powered IoT Sensor Nodes
For coin-cell powered IoT sensors and remote telemetry, the PIC16F723A-E/SO's 1.8V-5.5V supply range and nanoWatt XLP <1uA sleep currents enable multi-year battery life. The integrated 11-bit ADC reads thermocouples, thermistors, or 4-20mA current loops while the EUSART connects to sub-GHz radios like the MRF89XA. The PIC16F722A-E/SO (a 3.5KB sibling already on XAIPART) is the cost-down option when telemetry payload is smaller. Use the 256-byte EEPROM for persistent calibration and event counters; leverage deep sleep between wake-ups driven by the Watchdog Timer to maximize lifetime. The 28-SOIC footprint eases hand-soldering during prototyping before moving to QFN in volume.
おすすめ
Industrial Sensor Hubs
The PIC16F723A-E/SO serves as the controller in industrial sensor hubs because its MSSP supports I2C/SPI master interfacing to a wide range of industrial sensors (pressure, accelerometer, environmental). Its 20MHz CPU executes fast control loops while the EUSART outputs RS-485/RS-232 telemetry through external transceivers. The 28-pin SOIC package handles conformal-coating and harsh-environment manufacturing typical of factory-automation controllers. The 256-byte EEPROM logs non-volatile configuration and calibration data without external memory chips. Pair the MCU with an ADM3251E isolated transceiver for safe connection to plant networks and isolation barriers.
おすすめ
Consumer Appliance Controls
In washing machines, dishwashers, HVAC thermostats, and small kitchen appliances, the PIC16F723A-E/SO manages user inputs, displays, motor drivers, and sensor feedback with deterministic real-time behavior. The 11-bit ADC reads NTC temperature sensors, water-level probes, and motor-current shunts, while timers drive TRIAC and relay control. nanoWatt XLP keeps standby power below regulatory thresholds (Energy Star, EU eco-design). The wide VDD accepts both 3.3V and 5V rails from the same SMPS design, easing platform reuse. Existing XAIPART-listed siblings like PIC16F690-I/SO and PIC16F677-E/SO offer lower-memory footprints in the same SOIC package family for cost-tier product variants.
おすすめ
Medical Health-Monitoring Devices
For medical and wellness peripherals (blood-pressure monitors, pulse oximeters, thermometers), the PIC16F723A-E/SO delivers deterministic control with low quiescent draw for handheld battery operation. The 11-bit ADC captures pulse-oximeter photodiode signals conditioned through a transimpedance amplifier, while the EUSART links to Bluetooth or BLE modules for smartphone pairing. The extended -40C to +125C operating range handles sterilization and body-temperature limits. Verify IEC 60601 isolation between the MCU and any line-connected mains side, and use the 256-byte EEPROM for non-volatile patient-profile storage in compliance with applicable regulations.
おすすめ
LED Lighting and Smart Controls
The PIC16F723A-E/SO controls LED drivers and smart lighting nodes via PWM, I2C, and analog channels. With up to 20MHz CPU it computes mixed-dimming curves while the MSSP drives I2C-controlled LED drivers like the TLC59116 over long cable runs. nanoWatt XLP enables occupancy-sensor light fixtures that remain in deep sleep until motion is detected. The 7KB Flash stores lighting profiles and fade curves; the 192 bytes RAM holds runtime frame data. For higher-density driver systems, use the existing XAIPART PIC16F720-I/SO as a memory-reduced companion without leaving the PIC16 SOIC family.

設計ノート
Estimated: at 20MHz, VDD 5V, and full peripheral activity, IDD typically peaks around 6-7mA; in nanoWatt XLP deep sleep at room temperature IDD falls below 1uA. Place a 100nF ceramic decoupling capacitor as close as possible to VDD (pin 20) and a 10uF bulk capacitor at the board feed; this is critical for ADC accuracy during switching events on adjacent digital pins.
Route ICSPCLK and ICSPDAT (RA1 and RA0) away from high-frequency switching signals to prevent programming errors. Keep the MCLR#/VPP line short and add a 10k pull-up plus a 100nF decoupling cap to ground to improve ESD immunity. If using an external crystal, place the load capacitors within a few mm of OSC1/OSC2 to minimize parasitic capacitance.
Do not leave unprogrammed Configuration bits at their default-default values - explicitly set the oscillator selection, watchdog enable, low-voltage-programming enable, and code-protection bits before programming. The PIC16F723A shares the PIC16F/LF722A/723A silicon so pay attention to the errata sheet revision; some early revisions have ADC conversion anomalies under specific clock configurations.
コンプライアンス情報
RoHS compliant and lead-free (Pb-free matte tin finish) per Microchip ordering information. The -E extended temperature grade meets industrial and many automotive body-temperature profiles, but full AEC-Q100 qualification requires the dedicated automotive ordering code, not the standard -E/SO stock part.
