PIC16F726-E/SS - 8-Bit 20MHz 14KB Flash MCU 28-SSOP | Microchip
MPN: PIC16F726-E/SS ✓ Hoạt độngPIC16F726-E/SS Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM/EEPROM), peripherals, and I/O on one die. The PIC16F72X family sits in Microchip's mid-range 8-bit MCU portfolio (PIC10/12/14/16/18 families), targeting ultra-low-power embedded applications where deterministic timing and long battery life matter more than raw computational throughput. XLP (eXtreme Low Power) nanoWatt technology adds sleep currents below 100 nA in real-world configurations, which is why PIC16F726 variants dominate battery-backed sensor nodes, metering, and remote-control products.
Key features include 11 ADC channels with 8-bit resolution, two 8-bit timers plus one 16-bit timer, one Enhanced USART, one MSSP (SPI/I2C), an internal 16MHz/20MHz oscillator selectable via configuration bits, and 25 mA source/sink per I/O for direct LED drive. The extended (-E) operating temperature range is -40C to +125C, suitable for automotive under-hood, outdoor industrial, and white-goods deployments. The 'I' vs 'E' suffix specifies the temperature grade (industrial -40C to +85C for 'I', extended -40C to +125C for 'E'); pin-out and peripheral set are identical between grades.
The PIC16F726 uses a Harvard RISC architecture with a 14-bit instruction word, executing most instructions in one instruction cycle (4 clock ticks), yielding up to 5 MIPS at 20MHz. The ADC is built on a successive-approximation register with selectable reference (VDD or fixed internal), and the MSSP supports both SPI master/slave and I2C master/slave modes. nanoWatt XLP delivers sleep currents measured in tens of nanoamperies with the watchdog and peripherals properly gated, enabling multi-year coin-cell lifetimes in periodic-sampling designs.
Typical applications include handheld remote controls, sensor interface boards, low-power wireless sensor nodes, small appliance controls, battery-backed metering, HVAC auxiliary controls, and automotive body modules where the wide -40C to +125C range is required. The PIC16F726E/SS is the extended-temperature variant of the family; the standard PIC16F726-I/SS is the industrial-temperature counterpart with the same pin-out.
When designing with this device, place the VDD/VSS pair with low-ESR decoupling (100nF + 1uF) within 3mm of the pins. Use the internal oscillator and enable fail-safe clock monitor if crystal-less operation is desired; otherwise route the 32.768kHz secondary oscillator to Timer1 for RTC. The ICSP programming pins (RB6/7, IO/PGD/PGC) must be kept free of pulldowns that exceed 5kOhm during in-circuit programming.

Ứng dụng tiêu biểu
PIC16F726-E/SS phù hợp cho 7 Áp dụngs: Battery-Backed Remote Control / Sensor Node, HVAC Auxiliary Control Board, Automotive Body / Comfort Module, White Goods and Small Appliance Control, Smart Metering and Energy Monitoring, Industrial Sensor Interface Board, Consumer Electronics - Toy / Educational Robotics.
Battery-Backed Remote Control / Sensor Node
The PIC16F726-E/SS is engineered for battery-powered wireless sensor nodes and handheld remote controls where sub-100 nA sleep current and the -40C to +125C extended temperature grade are non-negotiable. nanoWatt XLP technology enables multi-year coin-cell lifetimes for periodic-sampling temperature, humidity, or occupancy sensors that wake every few seconds, sample the ADC, transmit over a low-power ISM link, and return to sleep. The 14 KB Flash holds a small RTOS-style scheduler plus app-specific logic, and the 368 B RAM comfortably buffers a few sensor frames. The MSSP port drives either SPI for sub-GHz radios (CC1101, SX1276) or I2C for sensor ICs (BME280, SHT31), while the 25 mA I/O source/sink can directly drive an LED indicator without a buffer. Wide 1.8-5.5 V VDD supports 2-cell alkaline (2.4-3.2 V), single Li-ion (3.0-4.2 V), and 5 V regulated rails equally well. Estimated: average current of 5 uA across 1 wake/sec duty cycling yields roughly 2 years on 2 x AA alkaline.

HVAC Auxiliary Control Board
In HVAC auxiliary control boards (zone dampers, fan controllers, programmable thermostats) the PIC16F726-E/SS provides enough Flash for a small control loop plus UI logic, with 11 ADC channels reading thermistors and pressure sensors, and 25 mA I/O capable of driving relays through transistors. The extended -40C to +125C temperature grade covers attic, rooftop, and outdoor unit environments where industrial-grade parts would thermally fault. The internal 16/20 MHz oscillator eliminates external crystal cost and survives mechanical vibration, while the 16-bit Timer1 with external 32.768 kHz option supports a software RTC for time-of-day scheduling. The MSSP/I2C connects to EEPROM-backed parameter storage; the EUSART links to wall-mounted remote keypads. Compared with discrete logic designs, the integrated MCU reduces BOM and PCB area, and nanoWatt XLP sleep allows backup-power operation during brown-outs.

Automotive Body / Comfort Module
The PIC16F726-E/SS in the -E (extended -40C to +125C) temperature grade is well-suited for non-safety automotive body and comfort subsystems: seat controllers, mirror adjusters, ambient lighting, door modules, and rain/light sensor interfaces. Automotive 12 V rails require wide VDD tolerance (this part supports 1.8-5.5 V with an upstream regulator), and the AEC-Q100-like qualification of Microchip PIC mid-range -E variants is standard for non-safety modules. 11 ADC channels handle ambient light, position feedback, and current sense, while the Enhanced USART connects to LIN transceivers or sub-MCU networks. nanoWatt XLP ensures quiescent current stays below typical OEM <100 uA key-off budgets when the module is dormant. Drop-in compatibility with PIC16F723A-E/SS and PIC16F724-E/SS within the same package family lets a single PCB host different program-memory SKUs without rework.

White Goods and Small Appliance Control
The PIC16F726-E/SS is widely deployed as the main controller in white goods such as rice cookers, induction cooktops, washing machines, microwave ovens, and air purifiers. The 11 ADC channels read thermistor / weight / flow sensors, two 8-bit timers generate PWM for motor / heater control, and the 16-bit Timer1 captures tachometer feedback for closed-loop fan or pump control. The -40C to +125C extended grade covers the heat-soak environments inside appliance enclosures, and nanoWatt XLP keeps standby power compliant with energy-star limits. The Enhanced USART enables service-port diagnostics, and the MSSP/SPI drives LED or OLED displays. Same-package family drop-ins (PIC16F727-I/SS, PIC16F723A-I/SS) support code-size migration without PCB rework.

Smart Metering and Energy Monitoring
In residential and small-commercial energy, gas, and water metering, the PIC16F726-E/SS combines the 14 KB Flash needed for segmented metering firmware with nanoWatt XLP sleep currents that enable 10+ year lithium-battery operation. The 11 ADC channels read current transformers, voltage dividers, and temperature sensors, while the 16-bit Timer1 with external 32.768 kHz crystal provides the RTC backbone for time-of-use billing. The MSSP port drives SPI-based EEPROM or FRAM for non-volatile log storage, and the Enhanced USART interfaces to wireless M-Bus, LoRa, or PLC modems. The extended temperature grade ensures operation in outdoor meter enclosures across climates, and the wide 1.8-5.5 V VDD supports both primary-cell and AC-line-derived power schemes.

Industrial Sensor Interface Board
In 4-20 mA loop-powered transmitters, isolated sensor front-ends, and Modbus / RS-485 field modules, the PIC16F726-E/SS provides the ADC, timers, and UART peripherals needed to bridge analog sensors to digital industrial networks. The 8-bit ADC with 11 channels handles multi-sensor PCB designs (pressure + temperature, or strain + temperature for compensation), and the Enhanced USART with RS-485 transceiver support is the standard field-bus interface. nanoWatt XLP keeps loop-powered devices within their 3.5 mA budget, and the -40C to +125C extended grade supports outdoor / cabinet-mounted industrial installations. Drop-in compatibility with PIC16F723-E/SS and PIC16F723A-E/SS lets designers right-size Flash for cost without PCB changes.

Consumer Electronics - Toy / Educational Robotics
The PIC16F726-E/SS is well-matched to consumer toys, educational robotics, and hobby kits that need an 8-bit MCU with generous Flash, PWM, and ADC at low cost. The 25 mA I/O source/sink directly drives small DC motors and LEDs without external buffers, two 8-bit timers plus the 16-bit Timer1 cover PWM channels for servo / motor control, and the 11 ADC channels read IR / line / potentiometer sensors. nanoWatt XLP keeps idle current low for battery-powered robots, and the extended temperature grade survives the heat generated by motor-driver PCB layouts. The 28-SSOP package is hand-solderable for prototyping, while the same-family drop-ins (PIC16F723A-E/SS, PIC16F722-I/SS) let kit makers tune cost per tier without changing the PCB.

Ghi chú thiết kế
Decouple VDD (pin 19) with a 100 nF X7R ceramic placed within 3 mm of the pin, plus a bulk 1 uF / 4.7 uF tantalum or ceramic near the MCU. For battery designs, place a low-quiescent LDO (TPS782 or MCP1700) upstream and gate it with an I/O pin if sub-uA standby is required. Always tie MCLR (pin 4) directly to VDD through a 10 kOhm pull-up; never leave MCLR floating - floating MCLR causes spurious resets. For ICSP, do not place any capacitor larger than 100 nF on the MCLR/VPP line.
Route ICSP pins RB6/PGC and RB7/PGD with no series resistors above 100 ohm and keep pulldowns >5 kOhm off these lines; otherwise in-circuit programming will fail. Keep the analog inputs (RA0-RA5) away from switching nodes; add a small RC (1 kOhm + 100 pF) low-pass filter at the ADC pin if the source impedance exceeds 2.5 kOhm, per the acquisition-time requirement in the datasheet. Provide a solid ground plane under the SSOP-28 to reduce ADC and oscillator noise coupling.
Configuration bits must be set correctly: disable the watchdog timer (WDTE) for low-power sleep, enable internal oscillator (FOSC = INTOSCIO), and clear the brown-out reset voltage appropriately for the supply rail. The 8-bit ADC requires the acquisition time to be honored in software - waiting only 1-2 us on a high-impedance source causes significant ADC error. Note that 'I' suffix parts are industrial grade (-40C to +85C) while 'E' suffix parts are extended grade (-40C to +125C); the data memory size, peripheral set, and pin-out are identical between grades. When migrating from PIC16F726 to PIC16F727 (same SSOP-28 pin-out) remember that the PIC16F727 reserves LCD-segment pins on PORTA/PORTB, which may break designs that drove general-purpose logic on those pins.
