PIC16F723T-I/ML Présentation
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals around an 8-bit data path. The PIC architecture uses a reduced instruction set (RISC) with Harvard bus topology, separating program and data memory for deterministic instruction timing. Within the broader semiconductor hierarchy, an 8-bit MCU sits below 16-bit and 32-bit MCUs in computational throughput, but excels in cost-sensitive, low-power embedded roles. The PIC16F723 specifically targets the sub-32KB Flash, sub-1KB RAM class where simplicity and nanoWatt XLP sleep currents matter more than raw MIPS.
Key differentiating features include nanoWatt XLP technology for sub-uA sleep currents, integrated PWM modules, watchdog timer, brown-out reset, and on-chip 16MHz internal oscillator that allows operation without an external crystal. The 28-QFN (ML) package with exposed thermal pad reduces footprint while providing solid thermal performance at the 20MHz speed grade.
The PIC16F723 employs a 14-bit instruction word with a two-stage pipeline, delivering approximately 5 MIPS instruction transfer to firmware. On-chip peripherals include a 10-bit ADC (referenced in family datasheets), comparators, enhanced USART, and capture/compare/PWM modules. The internal 16MHz oscillator is factory calibrated to within 1% across voltage and temperature.
Typical applications include battery-powered sensor nodes, consumer appliance controls, low-cost IoT edge devices, LED lighting controllers, and small industrial control boards. The combination of low cost, low power, and a mature toolchain makes it well-suited for high-volume embedded products where BOM cost dominates MCU selection.
When designing with this device, plan decoupling carefully: place a 100nF ceramic bypass close to VDD and a bulk capacitor near the exposed pad. For sleep-mode designs, follow Microchip's nanoWatt XLP application notes to minimize quiescent current and to leverage the on-chip LFINTOSC for timer-only operation.

Applications typiques
PIC16F723T-I/ML convient pour 6 applications: Battery-Powered Sensor Nodes, Consumer Appliance Controls, Low-Cost IoT Edge Devices, LED Lighting Controllers, Industrial Control Boards, Small Remote Controls and HIDs.
Battery-Powered Sensor Nodes
The PIC16F723T-I/ML is well suited to battery-powered sensor nodes thanks to its nanoWatt XLP technology, 1.8V-5.5V supply window, and 192B RAM. The internal 16MHz oscillator eliminates the external crystal, reducing BOM cost and quiescent draw. With 7KB Flash, designers can implement sensor sampling, threshold detection, and a small RF or UART protocol stack. The 25 I/O pins allow multiple sensor interfaces (I2C, SPI, ADC inputs) on a single MCU. Battery life of 1-3 years on a single CR2032 is achievable when the firmware aggressively uses sleep modes.

Notes de conception
Estimated: at VDD=3.3V, 16MHz internal oscillator, and 50% active duty, the PIC16F723T-I/ML draws roughly 2-3 mA active and <1 uA in nanoWatt XLP sleep. Place a 100nF X7R ceramic bypass within 3mm of the VDD pin (pin 7) and a 4.7uF bulk capacitor near the exposed pad (pin 28) to handle inrush during PWM transitions. For battery designs, follow Microchip AN1267 nanoWatt XLP tips to keep sleep current at the documented minimum.
The 28-QFN (ML) package's exposed thermal pad (pin 28) MUST be soldered to a PCB pad connected to VSS. Per IPC-7351 nominal-land-pattern guidelines, the EP pad should be a continuous copper pour with at least 8 thermal vias (0.3mm drill, 0.5mm pitch) to the inner ground plane. Skipping the EP soldering causes the junction temperature to rise 20-30C above ambient, potentially derating reliability in industrial -40C to +85C environments.
Do not pull MCLR (pin 24) directly to VDD without a series resistor - use the typical 10k pull-up. The internal 16MHz oscillator is factory-calibrated to 1% but drifts with VDD; for UART or USB timing, add an external crystal or resonator on RA6/RA7. Configuration-word settings (WDTE, LVP, etc.) must match the firmware linker script - a wrong CONFIG can lock the part or disable the ICSP programming pins RB6/RB7.
