PIC16F1823T-I/ST 개요
An 8-bit microcontroller (MCU) is a single-chip computer optimized for embedded control tasks, integrating a CPU, non-volatile program memory, RAM, peripherals, and I/O on one die. Within the semiconductor taxonomy, an MCU sits below microprocessor and above discrete logic, and the PIC16 family occupies the mid-range 8-bit niche defined by a 14-bit instruction word and RISC pipeline. XLP technology then adds deep-sleep current in the tens of nanoampere range, enabling battery-sourced products to run for years on a single cell.
Key features of the PIC16F1823T-I/ST include active current consumption in the microampere range at full 32 MHz operation, sub-microampere sleep current, an MI2C/SPI/I2C peripheral set, on-chip mTouch capacitive sensing hardware, and a CTMU charge-time measurement unit for temperature, capacitive touch, and time-of-flight measurements. The internal 32 MHz oscillator removes the need for an external crystal in most designs, simplifying BOM and reducing PCB area.
The device is fabricated on a low-power CMOS process and uses a modified Harvard architecture with a 14-bit instruction word. Core peripherals include a 10-bit ADC up to 8 channels, enhanced PWM, configurable logic cells, and a peripheral pin select (PPS) module that remaps digital peripherals to any I/O, giving layout engineers full freedom on 14 pins.
Typical applications include battery-powered sensor nodes, IoT edge nodes, low-power remote controls, LED lighting controllers, capacitive touch user interfaces, and consumer white goods. Designers choose this part when small package, low quiescent current, and flexible peripheral routing matter more than raw CPU throughput.
When designing with the PIC16F1823, ensure Vdd decoupling with a 100 nF ceramic capacitor within a few millimeters of the pin, and follow Microchip's ICSP guidelines if in-circuit programming is required. Note that the 'T' suffix denotes tape-and-reel packaging, 'I' denotes the -40C to +85C industrial temperature grade, and 'ST' indicates the 14-pin TSSOP.

일반적인 애플리케이션
PIC16F1823T-I/ST 적합 용도: 7 애플리케이션s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, LED Lighting Controller, Low-Power Remote Control, Industrial Sensor Transmitter, Consumer White Goods Control, Automotive Body Electronics.
Battery-Powered IoT Sensor Node
The PIC16F1823T-I/ST fits battery-powered IoT sensor nodes because its nanoWatt XLP sleep current drops below 50 nA, while the integrated 32 MHz internal oscillator eliminates external crystals. Designers wire it to a sensor via the 10-bit ADC and ADC-with-computation mode, then wake the part on a periodic interrupt to read and return to sleep. The 1.8 V to 5.5 V Vdd range supports single-cell Li-ion, 2xAA, or coin-cell operation, and the 14-TSSOP package is small enough for coin-cell form factors.
추천
Capacitive Touch User Interface
The PIC16F1823T-I/ST is ideal for capacitive touch keypads thanks to its on-chip mTouch peripheral and CTMU charge-time measurement unit, which together implement up to 12 touch buttons without external circuitry. The 32 MHz CPU can sample the touch matrix faster than 100 Hz per channel, and the 10-bit ADC with computation offloads filter and threshold logic to hardware. Low sleep current keeps battery-powered remotes and door locks alive for years.
추천
LED Lighting Controller
The PIC16F1823T-I/ST drives multi-channel LED strings via its enhanced PWM modules with configurable frequency and resolution, allowing smooth dimming from 0 to 100%. The 32 MHz core executes dimming algorithms and color-mixing math without breaking a sweat, and the wide Vdd range simplifies direct driving from 3.3 V or 5 V rails. Designers use the CTMU and ADC for ambient-light feedback and temperature fold-back, closing the loop on a smart lighting fixture.
추천
Low-Power Remote Control
The PIC16F1823T-I/ST suits handheld remote controls because its XLP sleep mode draws under 50 nA, allowing coin-cell-powered remotes to last for years. The integrated 32 MHz internal oscillator and 10-bit ADC with computation handle IR or RF transmission and battery-voltage monitoring without external components. Peripheral pin select (PPS) lets designers route the UART to any GPIO, easing PCB layout of compact remote enclosures.
추천
Industrial Sensor Transmitter
The PIC16F1823T-I/ST is well-suited to industrial 4-20 mA loop or wireless sensor transmitters because its 5.5 V max Vdd is compatible with 24 V industrial rails after regulation, and its -40C to +85C industrial temperature grade handles factory-floor environments. The 10-bit ADC with computation offloads calibration and linearization, while the I2C/SPI/USART peripherals drive external DACs or transceivers. The 14-TSSOP package is small enough to fit inside standard M12 sensor heads.
추천
Consumer White Goods Control
The PIC16F1823T-I/ST fits low-cost consumer white goods such as coffee machines, blenders, or air purifiers where cost-sensitive controllers handle user input, sensor reading, and motor or heater switching. The PWM modules drive triacs or relays via optocouplers, while the EUSART links to displays or wireless modules. nanoWatt XLP standby keeps wall-powered appliances within stringent energy-consumption regulations such as Energy Star.
추천
Automotive Body Electronics
The PIC16F1823T-I/ST can serve in non-safety automotive body modules such as interior lighting, seat controllers, or mirror adjusters, where its industrial -40C to +85C grade tolerates cabin temperatures. The 32 MHz core runs CAN or LIN stacks at standard bit rates, and the 10-bit ADC reads position sensors and switches. Designers use the extended -40C to +125C 'E' variant for under-hood or door-module placement.

설계 노트
Estimated: at Vdd = 3.3 V, the PIC16F1823 active current at 32 MHz is roughly 4-6 mA, while XLP sleep current is under 50 nA. Place a 100 nF ceramic decoupling capacitor within 3 mm of the Vdd pin (pin 1) and a bulk 10 uF cap on the rail if the source impedance is high. For battery-powered designs, route the MCLR pin through a 10 kohm pull-up to avoid spurious resets that drain batteries.
At typical 5 V operation, the PIC16F1823T-I/ST dissipates around 30 mW of heat, well within the 14-TSSOP package's 100 C/W thermal resistance. Designers do not need a heatsink; however, ensure ambient temperature stays inside the industrial -40C to +85C window specified by the 'I' suffix. For applications above +85C, choose the 'E' extended grade (-40C to +125C).
The 14-TSSOP package has a 0.65 mm pitch, which requires a fine-pitch reflow stencil (0.15-0.20 mm apertures). Keep the ICSP signals (ICSPCLK on RB6, ICSPDAT on RB7) on a separate test-pad footprint for production programming. Pull ICSPCLK low with a 10 kohm resistor to prevent floating during normal operation.
Do not leave MCLR floating - either tie it to Vdd through a 10 kohm resistor or wire it to a supervisor/reset circuit. Avoid using the internal 32 MHz oscillator with I2C at speeds above 400 kHz without enabling the PLL or a higher-precision clock source. When migrating from PIC16F1823 to PIC16LF1823, check that the application stays within the LF's 3.6 V maximum Vdd.
