PIC16F723A-I/SS 개요
An 8-bit PIC microcontroller is a compact, single-chip computer built on a Harvard RISC architecture that executes one instruction per clock cycle (except branches). The PIC16 mid-range core provides 35 single-word instructions, deterministic timing, and a small footprint, making PIC16F devices a workhorse for embedded control in appliances, sensors, and low-power industrial nodes. They sit in the hierarchy: microcontroller -> 8-bit MCU -> embedded controller -> semiconductor.
Key differentiating features include 11-channel 8-bit ADC, two comparators, enhanced CCP modules, MSSP (SPI/I2C) and EUSART (asynchronous serial) peripherals, and nanoWatt XLP modes with typical currents below 1 uA in sleep with WDT enabled. The on-chip 16-level voltage regulator and brown-out reset improve robustness in noisy or battery-depleted environments.
Architecturally, the PIC16F723A uses a modified Harvard core with separate program (Flash) and data (RAM) buses, 14-bit wide instructions, and a peripheral set optimized for mixed-signal control. The integrated 20 MHz internal oscillator eliminates external crystals in most designs, reducing BOM cost. The 28-pin SSOP variant (suffix /SS) supports surface-mount assembly while preserving pin compatibility with the SOIC (/SO), SPDIP (/SP), and QFN (/ML) siblings for PCB layout reuse.
Typical applications include battery-powered sensor nodes, household appliances, low-power remote controls, HVAC thermostat controls, and small consumer appliances where low sleep current, on-chip ADC, and serial peripherals (EUSART + MSSP) cover the bulk of I/O needs without external components.
When designing with this device, plan the oscillator start-up timer, watchdog timer, and brown-out reset behavior carefully during firmware bring-up. The internal oscillator is factory calibrated to within 1% across voltage and temperature, but high-accuracy UART or USB timing still benefits from a crystal.
This page consolidates distributor pricing, package-pinned drop-in alternatives, and practical design notes that are not found in the manufacturer datasheet alone - giving engineers a single reference for part selection, second sourcing, and layout decisions.

일반적인 애플리케이션
PIC16F723A-I/SS 적합 용도: 7 애플리케이션s: Battery-Powered Sensor Nodes, Household Appliance Control, HVAC Thermostat Controllers, Low-Power Remote Controls, Industrial Sensor Conditioning, Small Consumer Appliances and Toys, Automotive Body and Lighting Modules.
Battery-Powered Sensor Nodes
The PIC16F723A-I/SS fits battery-powered sensor nodes through its nanoWatt XLP extreme low-power technology, which delivers typical sleep current below 1 uA with WDT enabled and under 50 nA with WDT disabled. Its wide 1.8V to 5.5V VDD range lets a single design run from 2xAA alkaline, CR2032 coin cell, or a regulated 3.3V rail, eliminating the need for multiple variants. The 11-channel 8-bit ADC captures analog signals from temperature, light, and pressure sensors while the MSSP and EUSART peripherals stream data over I2C, SPI, or UART links to a host radio. Estimated battery life at 1 sample per minute exceeds 5 years from a 600 mAh CR2032.
추천
Household Appliance Control
The PIC16F723A-I/SS powers household appliance control boards in washing machines, dishwashers, microwave ovens, and rice cookers, where its 7 KB Flash accommodates state-machine firmware plus user-interface routines. The two ECCP modules drive triac-controlled AC loads for heater elements or motor speed control, while the on-chip comparators monitor over-current and zero-cross events for safe phase-angle control. With 25 digital I/O pins the device drives seven-segment displays, keypads, LED status indicators, and buzzer feedback without external I/O expanders, keeping the BOM cost low in cost-sensitive consumer markets.
추천
HVAC Thermostat Controllers
The PIC16F723A-I/SS is a strong fit for HVAC wall thermostats thanks to its 11-channel 8-bit ADC that reads multiple NTC10k temperature sensors, setpoint potentiometers, and humidity probes in parallel. The MSSP peripheral talks to the LCD display over I2C while the EUSART exchanges data with the HVAC indoor unit over a wired link or simple RF bridge. nanoWatt XLP sleep modes below 1 uA let the thermostat run for over a year on three AA cells when not actively driving the LCD, and the -40C to +85C industrial temperature range covers unheated equipment closets.
추천
Low-Power Remote Controls
Infrared and sub-GHz remote controls benefit from PIC16F723A-I/SS nanoWatt XLP modes, where typical sleep current under 1 uA lets the device run for years on a single CR2032 coin cell. The EUSART generates the 38 kHz IR carrier or interfaces to an external sub-GHz transmitter IC over SPI, while the on-chip ECCP module produces precise timing for protocol bit-banging when needed. 7 KB Flash comfortably stores NEC, RC5, or proprietary IR protocols plus button debounce and LED-driving state machines without external memory.
추천
Industrial Sensor Conditioning
Industrial sensor-conditioning front ends leverage the PIC16F723A-I/SS 8-bit ADC, two on-chip comparators, and 1.8V to 5.5V supply range to digitize 4-20 mA loops, RTD bridges, and digital inputs in the same package. The MSSP and EUSART peripherals backhaul data over RS-485 or I2C to a PLC or gateway, while the brown-out reset and watchdog timer ensure reliable operation in 24V industrial bus environments. Designers can replace a discrete op-amp + ADC + supervisor design with a single MCU, cutting BOM cost in half on multi-channel analog sensor boards.
추천
Small Consumer Appliances and Toys
Small consumer products such as electronic toys, toothbrushes, kitchen timers, and battery-powered massagers use the PIC16F723A-I/SS to consolidate motor control, button input, LED driving, and audio feedback into one 28-pin SSOP chip. The two ECCP modules generate PWM for brushed DC motors or LED dimming, while the 11-channel ADC reads battery voltage, touch sensors, and analog joysticks. nanoWatt XLP extends play time beyond 30 hours on a single 600 mAh Li-ion cell, and the 5.30 mm wide SSOP body fits inside slender consumer-product housings.
추천
Automotive Body and Lighting Modules
Automotive body-control modules and interior LED lighting benefit from the PIC16F723A-I/SS enhanced peripherals, including two ECCP channels for LED dimming and a 4-channel hardware PWM for RGB ambient lighting. The on-chip comparators monitor current-sense amplifiers on LED strings for open-circuit and short-circuit detection, while the EUSART links the module to the CAN-ready gateway through a MCP2515 external controller. Designers should note that the I-grade (-40C to +85C) variant covers interior cabin applications; under-hood designs require the E-grade (-40C to +125C) PIC16F723A-E/SS or AEC-Q100 qualified PIC16F families.

설계 노트
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 19, plus a bulk 1 uF to 10 uF tantalum or ceramic on the same rail. For battery designs targeting under 1 uA sleep current, avoid external pull-ups on MCLR that exceed 50 kohm; the internal weak pull-up is enabled by the MCLRE configuration bit but can be overpowered by low-impedance external networks. Enable the brown-out reset (BOR) via configuration bits to prevent code runaway during battery brown-out events.
Route the analog ADC inputs (AN4-AN11) away from digital switching lines such as PWM outputs and the oscillator pins to minimize crosstalk. Place the AVSS and VSS pins at a single ground star point, and keep the analog reference (if used externally) traces short and guarded with a ground ring. The 28-pin SSOP body is only 5.30 mm wide, so use 0.20 mm traces with 0.10 mm clearance to maximize routing density under the package.
Do not assume the internal 16 MHz oscillator is accurate enough for UART at 115200 baud - factory calibration is within 1% but not within 0.4% required for high-speed async serial. For UART above 38400 baud, switch to a crystal on OSC1/OSC2 or use the MSSP SPI peripheral instead. Also, when migrating from PIC16F723 to PIC16F723A silicon, review the Microchip errata sheet - some early PIC16F723A revisions affected ADC acquisition timing and required a firmware workaround that is fixed in later revisions.
The 28-pin SSOP package dissipates roughly 200 mW at 5V and 20 MHz across the full industrial temperature range, well within the package's 150 C junction limit without forced airflow. Estimated: at room temperature with the standard 4-layer PCB copper pour, theta_JA is approximately 80 C/W, giving a 16 C rise at 200 mW. For sealed enclosures without convective cooling, derate CPU clock or supply voltage to keep junction temperature below 100 C.
