PIC16F726T-I/SS - 14KB Flash 8-bit MCU, 20MHz, 28-SSOP | Microchip
MPN: PIC16F726T-I/SS ✓ פעילPIC16F726T-I/SS סקירה
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture 8-bit MCU with on-chip flash, EEPROM, RAM, peripherals, and a CPU optimized for deterministic embedded control. PIC microcontrollers sit in the broader hierarchy of microcontrollers -> microprocessors -> semiconductor ICs. Microchip's PIC16F series occupies the mid-range (PIC16) tier, which adds richer peripherals, more memory, and C-optimized architectures over the baseline PIC10/12/14 families, while keeping the instruction-set simplicity that made the PIC architecture popular for low-power and motor/lighting control.
Key features of the PIC16F726T-I/SS include nanoWatt XLP technology for sub-microamp sleep currents, an integrated 8-channel 8-bit ADC with on-chip voltage reference, multiple timers (Timer0, Timer1, Timer2), enhanced PWM/capture/compare peripherals, and a wide 1.8V to 5.5V operating voltage range. It supports in-circuit serial programming (ICSP) and self-programming via flash program memory.
Typical applications include home-automation sensor nodes, battery-powered wireless transmitters, white-goods control boards, lighting sub-system entry, low-power metering, and general-purpose embedded logic. The wide voltage range and very low sleep current make it attractive for IoT end nodes and energy-harvesting systems where quiescent draw dominates battery life. The 28-SSOP footprint also suits compact designs in industrial control panels.
When designing with this device, select the lowest practical clock speed in active mode and keep the MCU in sleep between events; nanoWatt XLP gives the most benefit when firmware stays in sleep for >90% of the duty cycle. Use the internal 16MHz HFINTOSC when timing tolerance allows, and select a slower LFINTOSC for sleep wake-up timing. For firmware development, MPLAB X IDE plus the XC8 compiler is the canonical toolchain; no external programmer is required if ICSP header pins are exposed.

Battery-Powered IoT Sensor Node
The PIC16F726T-I/SS's nanoWatt XLP technology with sub-microampere sleep current makes it ideal for battery-powered IoT sensor nodes that wake briefly to sample and transmit, then return to sleep. The 1.8V-5.5V Vdd range accommodates single-cell lithium, two-AA alkaline, or 3.3V coin-cell chemistries without level shifters. The 8-channel 8-bit ADC handles typical sensor inputs (temperature, light, gas) directly, while the 14KB flash accommodates firmware stacks including MPLAB XC8 C code, simple drivers, and a small wireless-protocol state machine. With 20MHz maximum CPU speed and HFINTOSC, sensor reads and conditional wake decisions execute fast enough that average current stays below 50uA in typical duty-cycled scenarios.

הערות תכנון
Estimated: at Vdd=3.3V, full 20MHz active CPU, IO loaded lightly, the PIC16F726T-I/SS draws approximately 2-3 mA active. In sleep mode with peripherals disabled, nanoWatt XLP drops this to under 100 nA. For battery-powered designs, keep the MCU in sleep for >90% of the duty cycle and wake only via Watchdog Timer or external interrupt to maximize battery life. Use HFINTOSC for fast wake, then switch to LFINTOSC for low-power waiting periods.
Place a 100nF decoupling capacitor as close as possible to the Vdd pin (pin 6) and a second 100nF near the Vss pins (7 and 28). For analog accuracy, add a 10uF bulk capacitor near the Vdd pin and a separate analog AVdd pin decoupling capacitor if used. The 28-SSOP package has 0.65mm pitch; ensure solder paste stencil apertures meet IPC-7525 standards for fine-pitch SSOP, and avoid ground-plane cuts under the IC body to minimize thermal stress and EMI.
Route the ICSP clock (RB6/ICSPCLK) and data (RB7/ICSPDAT) signals with short, direct traces to a 6-pin ICSP header (or test pads) for in-circuit programming and debugging. Keep the MCLR/VPP line separate from any high-current switching traces and include a 10k pull-up to Vdd to ensure reliable reset. If the MCLR pin is unused as reset, configure it as digital input with internal pull-up disabled to avoid spurious resets from noise.
For ADC measurements above 1% accuracy, use the on-chip voltage reference or an external low-noise reference such as the MCP1501. Avoid toggling digital I/O on adjacent pins during ADC conversions, and oversample digitally in software to improve effective resolution. Place the analog input traces over a continuous ground plane and keep digital traces away from analog signal paths.
Do not exceed 5.5V on Vdd or apply voltage to any pin before Vdd is applied (latch-up risk on CMOS I/O). The "/SS" suffix indicates 28-SSOP package; verify the PCB footprint matches SSOP 0.65mm pitch, not SOIC 1.27mm pitch. The "I" in -I/SS indicates industrial -40C to +85C temperature range; for AEC-Q100 automotive applications, use the automotive-graded PIC16F equivalent from the same family.
