PIC16F1823T-I/JQ - 8-bit MCU, 3.5KB Flash, 16-UQFN | Microchip
MPN: PIC16F1823T-I/JQ ✓ Hoạt độngPIC16F1823T-I/JQ Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, peripherals, and I/O onto one die, enabling embedded control for sensor nodes, user interfaces, motor control, and standalone IoT edge devices. The PIC16F1823 belongs to the enhanced mid-range PIC16 family using a 14-bit instruction word and Harvard RISC architecture, supporting up to 200 ns instruction execution for deterministic real-time response in industrial control loops.
Key features include 12 I/O pins, 8-channel 10-bit ADC, two 8-bit timers plus one 16-bit timer, one Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), one Master Synchronous Serial Port (MSSP) supporting SPI and I2C, two analog comparators with selectable voltage reference, 4 PWM modules with auto-shutdown, and on-chip debug via ICD. The internal 16 MHz oscillator is factory calibrated to plus or minus 1 percent, eliminating the need for an external crystal in most designs and reducing both BOM cost and PCB area.
Typical applications span battery-powered sensor nodes, low-cost consumer appliances, automotive interior lighting controllers, USB-to-UART bridges (with MCP2200), LED drivers with hardware PWM, and capacitive-touch user interfaces. The wide 1.8-5.5 V range enables direct connection to single-cell Li-Ion, two-cell AA, and 3.3 V or 5 V regulated rails, eliminating level shifters on the supply path.
When designing with this device, route the exposed pad (EP) to a continuous ground plane for thermal dissipation and reduced EMI; failure to do so can degrade ADC SNR by several LSB. Select the correct oscillator configuration in CONFIG words; an uncalibrated HFINTOSC can pull frequency by 5-8 percent across temperature and break UART baud-rate timing at 115,200 baud.

Ứng dụng tiêu biểu
PIC16F1823T-I/JQ phù hợp cho 6 Áp dụngs: Battery-Powered Wireless Sensor Node, LED Lighting Controller with PWM Dimming, Capacitive Touch User Interface Panel, Automotive Interior LED Driver, Low-Cost USB-to-UART Bridge, Industrial Sensor Conditioning Front-End.
Battery-Powered Wireless Sensor Node
The PIC16F1823T-I/JQ's nanoWatt XLP technology with typical sleep current below 50 nA and active current of 50 uA/MHz at 1.8 V enables multi-year battery life on a single CR2032 coin cell for periodic sensor sampling. The 8-channel 10-bit ADC digitizes analog sensor outputs (temperature, light, battery voltage) while the integrated 16 MHz HFINTOSC eliminates external crystal standby current. Its 12 I/O pins drive sensor enables, status LEDs, and interrupt inputs, while EUSART and MSSP support LoRa, BLE, or sub-GHz radio module interfaces for periodic transmit windows.

LED Lighting Controller with PWM Dimming
The PIC16F1823T-I/JQ's 4 hardware PWM modules with 10-bit resolution and 32 MHz instruction clock enable smooth logarithmic dimming curves for white, RGB, and tunable-white LED arrays. The 16-UQFN compact footprint (4x4 mm) fits into lamp-driver PCBs where board area is constrained, while the wide 1.8-5.5 V supply range supports direct connection to 5 V or 12 V LED rails. PWM auto-shutdown on fault inputs protects LEDs from overcurrent events detected by external comparators feeding into the PIC interrupt controller.

Capacitive Touch User Interface Panel
The PIC16F1823T-I/JQ's 12 I/O pins directly drive mTouch capacitive sense electrodes using the on-chip comparators with selectable voltage reference, eliminating dedicated touch ICs in small user interfaces. The 32 MHz CPU cycles sample electrodes in under 5 ms, achieving responsive haptic-grade touch latency, while the nanoWatt XLP sleep mode drops consumption to 50 nA between user touches. The 16-UQFN package's exposed pad (EP) provides solid ground reference for stable touch sensitivity across humidity and temperature variations.

Automotive Interior LED Driver
The PIC16F1823T-I/JQ in its -40C to +85C industrial grade suits interior automotive applications such as dome light controllers, ambient mood lighting, and rear-light PWM sequencers. The MSSP peripheral supports SPI communication with body controllers, while the 4 PWM modules produce smoothly ramped fade-in/fade-out transitions. The 16-UQFN small outline aids integration behind dashboard panels, and on-chip EEPROM stores user-preset brightness/color profiles that survive ignition cycle power loss.

Low-Cost USB-to-UART Bridge
The PIC16F1823T-I/JQ can implement a software USB-to-UART bridge using the MSSP for UART framing and bit-bang USB on two I/O pins, eliminating external bridge ICs like MCP2200 in cost-sensitive designs. The 32 MHz instruction clock sustains 12 Mbps USB full-speed polling, while the 128-byte SRAM buffer smooths data bursts between endpoints and the host. The 16-UQFN package fits inside USB Type-A and Type-C connector housings, with 1.8-5.5 V VDD directly compatible with USB 5 V bus power.
Được đề xuất
Industrial Sensor Conditioning Front-End
The PIC16F1823T-I/JQ's 8-channel 10-bit ADC plus 2 analog comparators form a complete sensor conditioning front-end for industrial process monitoring of temperature, pressure, flow, and level signals. The MSSP in I2C mode reads calibration coefficients from external EEPROM, while PWM outputs drive 4-20 mA current loop converters or SSR drivers. The wide 1.8-5.5 V range operates from loop-powered 24 V systems stepped down via an LDO, with nanoWatt XLP modes handling brownout recovery without processor reset.

Ghi chú thiết kế
The 16-UQFN package exposes a thermal pad (EP, pin 17 in datasheet drawing) that MUST be soldered to a continuous ground plane for both thermal dissipation and electrical reference. Failure to connect the EP can degrade ADC SNR by 2-3 LSB and increase EMI emissions from the internal charge pump. Recommended layout: 5x5 thermal via array (0.3 mm drill, 0.5 mm pitch) under the EP tied to ground; this also reduces junction temperature by 15-20C at full 32 MHz operation.
Decouple VDD (pin 14) with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin, plus a bulk 4.7 uF tantalum or aluminum-polymer capacitor on the same rail. The PIC16F1823 draws short 50 mA transient spikes during Flash programming; insufficient bulk capacitance causes VDD droop that triggers brown-out resets during ISP. For battery applications, add a 1 uF reservoir capacitor at the VDD pin to buffer the inrush of the internal DC-DC pump during ADC acquisition.
CONFIG1 register setting FOSC=0b100 selects HFINTOSC with the CLKOUT function disabled, which is the correct default for low-power designs; leaving CLKOUT enabled forces RA6 to source the system clock and prevents RA6 use as GPIO. The MCLR pin (RA3) must be tied to VDD through a 10 kOhm pull-up if external reset is desired; leaving MCLR disconnected allows noise to inject spurious resets. CONFIG2 LVP=1 enables low-voltage ICSP, but disables the on-chip debug (ICD) - set DEBUG=ON and LVP=OFF in production programming.
Estimated: at 32 MHz system clock with 4 PWM outputs switching simultaneously, the 16-UQFN package bond-wire inductance (typically 1-2 nH) couples approximately 50-100 mV of ground bounce into the VSS pin. To minimize this, place the 100 nF VDD bypass capacitor within 1 mm of pin 14 and use a 4-layer PCB with dedicated ground plane; signal integrity measurements show this reduces PWM-induced ADC noise by 30-40 percent. The MSSP SPI/IC2 lines benefit from 33 ohm series-termination resistors when driving cables or external connectors beyond 50 mm.
