PIC16F723T-I/SS 개요
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus and a Harvard or modified-Harvard architecture, typically executing one byte per instruction cycle. The PIC16F family uses a RISC core that executes most instructions in a single instruction cycle, allowing deterministic timing critical for real-time control. Within the broader taxonomy, PIC16F MCUs sit under Microcontrollers, sub-segmented into the 16-bit PIC24/dspic and 32-bit PIC32 families for higher performance, sharing a common MPLAB development ecosystem.
Key features include eleven analog channels of 8-bit ADC, two 8-bit and one 16-bit timers, an Enhanced USART, one MSSP (SPI/I2C), a 16-level hardware comparator, and up to 25 digital I/O pins. The integrated 16 MHz internal oscillator is factory calibrated to ±1%, eliminating the need for an external crystal in many designs and reducing BOM cost.
The PIC16F723 uses Microchip's enhanced mid-range core with a 14-bit instruction word and a two-stage pipeline that delivers 200 ns instruction execution at 20 MHz. nanoWatt XLP technology includes multiple power-managed modes (Run, Idle, Sleep) and a watchdog timer that can run from an ultra-low-power dedicated internal oscillator, making the device well suited to battery applications where the MCU spends most of its life in Sleep.
Typical applications include consumer remote controls, white-goods and small appliance control panels, low-end sensor nodes, battery chargers, smoke and CO detectors, and industrial sensor interfaces. Internal peripherals such as the Enhanced USART, MSSP and 11-channel 8-bit ADC cover most embedded sensing needs without external glue logic.
Design considerations for the PIC16F723 include ensuring the ICSP programming pins (RB6/RB7) remain accessible on the PCB for in-circuit programming and that the analog supply (AVDD) is properly decoupled from VDD when ADC channels are active. Pull-ups on I/O pins must be enabled in software via the WPUA/WPUB registers.

일반적인 애플리케이션
PIC16F723T-I/SS 적합 용도: 7 애플리케이션s: Consumer Remote Control, Battery-Powered Sensor Node, Smoke and CO Detector Controller, White Goods / Appliance Control Panel, Battery Charger / Power Bank Controller, Industrial Sensor Interface Module, USB HID Toy / Educational Board.
Consumer Remote Control
The PIC16F723T-I/SS fits handheld IR/RF remote controls because its nanoWatt XLP Sleep current stays under 1 µA and the 16 MHz internal oscillator removes the external crystal needed for IR carrier generation. The Enhanced USART can drive IR PWM modulation at 38 kHz carrier; the MSSP can interface an RF transmitter module. The 1.8 V to 5.5 V range lets the MCU run directly from 2x AAA cells, supporting multi-year battery life in typical standby duty cycles of <0.1%.
추천
Battery-Powered Sensor Node
The PIC16F723T-I/SS supports battery-powered wireless sensor nodes with multi-year runtime, thanks to typical Sleep currents below 1 µA and a Watchdog Timer running from an ultra-low-power dedicated oscillator. The 11-channel 8-bit ADC handles temperature, light, voltage and resistive sensors with internal 1.024 V / 2.048 V / 4.096 V references for ratiometric measurement, eliminating an external reference IC. The MSSP in SPI mode connects to low-power sub-GHz transceivers from the same PCB.
추천
Smoke and CO Detector Controller
The PIC16F723T-I/SS is widely used in residential smoke/CO detector controllers, where its 16-level programmable voltage reference and analog comparator directly drive the photoelectric chamber op-amp without external comparators. The 11-channel 8-bit ADC reads battery voltage, test button and chamber current; the 16-bit TMR1 drives the chirp oscillator, and Sleep-current behaviour under 1 µA preserves backup battery for years. UL 217 compliance is supported by the device's industrial temperature range and high-noise immunity.
추천
White Goods / Appliance Control Panel
The PIC16F723T-I/SS is a strong fit for washing-machine, dishwasher and oven control panels because the 11-channel 8-bit ADC reads multiple temperature sensors, water levels and keypads with internal references. The MSSP in I2C mode connects to LED display drivers and EEPROMs, while the Enhanced USART supports service/diagnostic handhelds. The wide 1.8-5.5 V range and noise immunity make it tolerant of motor-driver transients common on appliance PCBs.
추천
Battery Charger / Power Bank Controller
The PIC16F723T-I/SS can act as a state-machine controller for single-cell Li-ion chargers, USB power banks and DC-DC controllers, where the 16-level programmable CVREF and Enhanced USART allow charging-curve CC/CV tuning via serial commands. The 8-bit ADC reads battery voltage and current sense with internal reference, and the 16-bit TMR1 drives PWM outputs for switching converters. Sleep mode below 1 µA is critical for shelf-life in shipped products.
추천
Industrial Sensor Interface Module
The PIC16F723T-I/SS acts as the protocol-translation brain in industrial 4-20 mA / 0-10 V sensor interfaces, where its 8-bit ADC digitises analog sensors and the Enhanced USART/MSSP deliver Modbus RTU over RS-485 or SPI/I2C to a host PLC. Industrial temperature grade (-40C to +85C) and electromagnetic robustness match IEC 61000-4-x requirements when paired with isolated transceivers. The 28-SSOP footprint suits slim DIN-rail modules that require a small PCB outline.
추천
USB HID Toy / Educational Board
The PIC16F723T-I/SS can serve as the foundation of educational microcontroller boards and simple USB HID devices, where the 7 KB Flash and 192-byte RAM easily fit tiny programs and the Enhanced USART directly drives a low-cost USB-to-UART bridge like MCP2200 or CH340. The MPLAB Snap/PICkit 4 programming interface over RB6/RB7 is widely supported in schools, and the 28-SSOP footprint is friendly to breadboard-friendly breakout boards. Designers get a stable, well-documented platform with decades of Microchip tooling behind it.

설계 노트
The PIC16F723T-I/SS draws typical IPD (Sleep with WDT) current below 1 µA per the datasheet, but this assumes all peripherals disabled and I/O pins configured as outputs (not floating). Inputs left floating can draw additional leakage through their input-stage MOSFETs, particularly at high VDD; configure all unused pins as outputs driving low or enable the internal weak pull-ups. Estimated: at 5 V with one floating input, board-level Sleep current may rise to 5-10 µA.
Place 0.1 µF decoupling capacitors (X7R ceramic) on AVDD and VDD as close as possible to the respective SSOP28 pins, ideally within 3 mm to suppress switching transients. Add a 10 µF bulk aluminium-polymer or tantalum capacitor at the regulator output. Separate the analog ground plane (AVSS) from the digital ground plane (VSS) and join them at a single point under the MCU to minimise ADC conversion noise.
Ensure RB6 and RB7 (ICSP pins) remain accessible on the PCB through a programming header or test points, otherwise in-circuit programming requires rework. Pull-up enable on PORTB is configurable per pin, but the global RBPU bit in OPTION_REG must be cleared for any pull-ups to function - a common firmware porting mistake when migrating from older PIC16 baselines. Estimated: a single uninitialised pull-up on RB0 can drive Sleep current from <1 µA to >50 µA.
The 8-bit ADC on PIC16F723T-I/SS achieves approximately ±0.5 LSB linearity with a 6 µs acquisition time. Use the internal 1.024 V / 2.048 V / 4.096 V CVREF when measuring ratiometric low-level signals to eliminate switching-noise injection from external references. Place analog traces away from the PWM/CCP1 drive lines (RB3) and add a ground-keep-out guard ring around analog pins used at high impedance.
