PIC16F1823-E/ST Übersicht
An 8-bit PIC microcontroller (MCU) is a compact, low-cost, low-power programmable processor built on Microchip's RISC-based PIC architecture. It integrates CPU core, Flash program memory, data RAM, EEPROM, digital peripherals, and analog peripherals onto a single silicon die, and it sits within the broader semiconductor taxonomy as: microcontroller -> embedded processor -> semiconductor IC. The PIC16F1823 belongs to the enhanced mid-range (PIC16F1xxx) family that adds C compiler-friendly architecture, hardware multiplier, and nanoWatt XLP sleep modes suited to battery-powered designs.
Key features include: 32MHz internal oscillator (selectable HFINTOSC), 4x PLL, 10-bit ADC with up to 8 channels, two 8-bit timers plus one 16-bit timer, enhanced PWM with up to 4 outputs, on-chip voltage reference, fixed voltage reference (FVR), and ICSP (In-Circuit Serial Programming) support for low-voltage and high-voltage programming.
The PIC16F1823 is built on an enhanced Harvard RISC core with a 14-bit instruction word and hardware multiplier. Integrated peripherals including configurable logic cells (CLC), complementary waveform generator (CWG), and signal measurement timer (SMT) deliver functionality that historically required multiple external ICs, simplifying BOM and PCB layout.
Typical applications include low-power sensor nodes, battery-powered IoT devices, LED lighting controllers, consumer appliance user interfaces, and small motor control loops. The 14-TSSOP footprint suits compact designs where board area is constrained.
When designing with this MCU, account for the 32MHz internal oscillator tolerance (+/- 2% typical) and provide adequate decoupling (100 nF + 10 uF) near the VDD pin to suppress switching noise. Enable fail-safe clock monitor (FCM) for safety-critical applications.

Typische Anwendungen
PIC16F1823-E/ST ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, LED Lighting Controller, Consumer Appliance User Interface, Small DC Motor Speed Control, Industrial Sensor Transmitter, Wearable Health Monitor.
Battery-Powered IoT Sensor Node
The PIC16F1823-E/ST is well-suited for battery-powered IoT sensor nodes because of its nanoWatt XLP deep-sleep current under 50 nA typical and integrated 10-bit ADC with up to 8 channels. With 3.5KB Flash and 128B RAM it can host small C-compiled firmware for periodic sensor sampling, threshold logic, and low-rate LoRa/Sigfox/BLE wake-up signaling. The 32MHz HFINTOSC eliminates an external crystal for cost-sensitive nodes, while the extended -40C to +125C temperature range supports outdoor and industrial enclosures. Place a 100 nF decoupling capacitor within 5mm of the VDD pin and use sleep modes between acquisitions to extend coin-cell life to multi-year ranges.

LED Lighting Controller
The PIC16F1823-E/ST's enhanced PWM module (4 channels with up to 10-bit resolution) and configurable logic cells (CLC) enable multi-channel LED driving, dimming curves, and color mixing without external logic. The 32MHz core supports smooth PWM transitions and software-driven DLI/DMX-style protocols, while the 10-bit ADC can read ambient light sensors for closed-loop brightness control. The 14-TSSOP footprint fits into MR16 bulbs and small linear fixtures, and the 2.5V to 5.5V VDD range accepts direct Li-ion or 5V USB power.

Consumer Appliance User Interface
The PIC16F1823-E/ST is widely used in consumer appliance user-interface modules such as microwave keypads, coffee-machine displays, and small kitchen-appliance controllers. The 12 available I/O pins handle a 4x4 matrix keypad plus 7-segment display drive directly, the integrated 10-bit ADC reads NTC temperature probes for closed-loop cooking logic, and the EUSART communicates with the main appliance MCU for status updates. The 3.5KB Flash comfortably hosts C-compiled state-machine UI firmware, and the 14-TSSOP package mounts on compact daughter boards.
Empfohlen
Small DC Motor Speed Control
The PIC16F1823-E/ST's enhanced PWM, complementary waveform generator (CWG), and 16-bit SMT (signal measurement timer) provide all the building blocks for small brushed DC or uni-polar stepper motor control. The integrated 10-bit ADC reads back-EMF or shunt current for closed-loop speed regulation, and the 32MHz instruction throughput executes PID loops at sub-millisecond rates. The 14-TSSOP package drops onto compact motor boards inside fans, pumps, and small robotics actuators.

Industrial Sensor Transmitter
Industrial 4-20 mA loop-powered sensor transmitters leverage the PIC16F1823-E/ST's 2.5V to 5.5V operation, 10-bit ADC, and nanoWatt XLP deep-sleep mode to minimize loop-current consumption. With 128B RAM and 3.5KB Flash, the MCU handles sensor linearization, range scaling, and 4-20 mA DAC drive via PWM-filter. The extended -40C to +125C temperature range supports process-industry deployments in cabinets near heat sources, and the 14-TSSOP package fits inside standard sensor heads.
Empfohlen
Wearable Health Monitor
Wearable fitness bands and health patches benefit from the PIC16F1823-E/ST's tiny 14-TSSOP footprint, sub-50 nA deep-sleep current, and integrated 10-bit ADC for heart-rate, SpO2, and skin-temperature analog front-ends. The 32MHz core executes CMSIS-style signal-processing libraries for PPG and ECG feature extraction, and the EUSART interfaces with BLE modules for smartphone tethering. The 2.5V minimum VDD allows direct coin-cell operation without boost regulators.

Wichtigste Unterscheidungsmerkmale
- Extended -40C to +125C operating temperature range (vs. PIC16F1823-I/ST)
- Lowest memory cost in Microchip's 14-TSSOP PIC16 enhanced mid-range family (vs. PIC16F1825-I/ST)
- nanoWatt XLP extreme low-power technology with sub-50 nA sleep current (vs. PIC16F1613-E/ST)
Designhinweise
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 1) and a bulk 10 uF capacitor on the same rail near the MCU. The PIC16F1823-E/ST draws brief current pulses of 15-20 mA during ADC conversion and Flash write; insufficient decoupling causes ADC LSB jitter and brown-out resets. For battery applications, add a 100 ohm series resistor between VDD and the decoupling capacitor to slow edge transients.
Do not leave the MCLR/RA3 pin floating; either tie it to VDD via a 10 kohm resistor for normal operation or configure it as digital input with internal weak pull-up. A floating MCLR causes spurious resets. Also, when using the internal HFINTOSC at 32 MHz, verify the IRCF configuration bits match the expected frequency; an incorrect IRCF setting reduces ADC and PWM accuracy.
Route the ICSPDAT/ICSPCLK traces (RB7/RB6 or equivalent) so they share a clean ground with VSS; long parallel traces couple programming-clock noise into analog ADC inputs. Keep ADC traces short, guard them with a ground ring, and avoid running them parallel to PWM outputs. For TSSOP-14 footprints, use 0.65 mm pitch SOIC-compatible land patterns to ease hand-prototyping on breakout boards.
Estimated: at maximum clock 32 MHz with all peripherals active, the PIC16F1823-E/ST draws approximately 8-10 mA from VDD = 3.3V, yielding about 30 mW dissipation. With a TSSOP-14 theta_JA of approximately 100 C/W, junction temperature rise above ambient is roughly 3 C, well within the 125 C operating limit. No thermal management is required for typical embedded applications.
