PIC18F26Q10-E/SP - 8-bit 64MHz 64KB Flash MCU | Microchip
MPN: PIC18F26Q10-E/SP ✓ Hoạt độngPIC18F26Q10-E/SP Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory, peripherals and I/O. Within the broader semiconductor taxonomy the PIC18F26Q10 belongs to the 8-bit MCU family, the PIC® XLP™ 18Q sub-family, and Microchip's Functional Safety (FuSa) line; it sits inside the microcontroller -> embedded controller -> power management-aware signal processing node class. Its 5V-native operation increases noise immunity for industrial sensor and real-time control nodes.
Key features include a 10-bit ADC with computation (ADC2), a 5-bit DAC, two comparators, a zero-cross detect (ZCD), complementary waveform generator (CWG), 10-bit PWM with CCP, windowed watchdog timer (WWDT), hardware limit timer (HLT), CRC/SCAN accelerator, peripheral pin select (PPS) and four configurable logic cells (CLC). The CIP (Core Independent Peripherals) blocks let the CPU offload deterministic tasks, improving real-time response.
Architecturally, the part uses an 8-bit modified Harvard bus with a 16-bit instruction word, a hardware multiplier and 49 instructions; the 64 MHz internal oscillator drives a 16 MIPS instruction throughput. The non-volatile memory is rated for high-endurance Flash and EEPROM suitable for frequent parameter storage.
Typical applications include industrial sensor nodes, motor and pump control, white goods, automotive body and lighting subsystems, IoT edge nodes and low-power battery-powered metering. The Q10 family's noise-tolerant 5V I/O and CIP mix make it a strong fit for BLDC and AC-DC power-conversion auxiliary control.
When designing, prefer using the CLCs and CWG for hard-real-time signaling, leave the WWDT enabled for safety, and use ADC2 computation modes to average the analog channel in hardware before waking the CPU.

Ứng dụng tiêu biểu
PIC18F26Q10-E/SP phù hợp cho 6 Áp dụngs: Industrial Sensor Node, BLDC Motor and Pump Control, White Goods and Home Appliances, Automotive Body and Lighting, IoT Edge and Battery Metering, Auxiliary SMPS and Power Conversion.
Industrial Sensor Node
The PIC18F26Q10-E/SP is well matched to industrial 4-20 mA or 0-10 V sensor nodes: its 10-bit ADC2 with computation performs oversampling and digital filtering in hardware, freeing the CPU to manage Modbus RTU framing over UART. The 64 MHz core (16 MIPS) handles MODBUS CRC and linearization math while the WWDT and CRC/SCAN blocks deliver the deterministic self-test coverage expected by IEC 61508 SIL-1 designs. With 5V-native I/O it tolerates long cable runs in noisy factory floors.

BLDC Motor and Pump Control
In BLDC or single-phase pump control the PIC18F26Q10-E/SP drives the inverter through its Complementary Waveform Generator (CWG) and CCP-based PWM, producing dead-band-controlled high-side/low-side signals without CPU intervention. The ZCD detects mains zero-crossings to synchronize TRIAC firing in pump or AC-fan designs, while ADC2 samples back-EMF for sensorless commutation. The E temperature grade allows under-hood mounting where ambient exceeds 85C during compressor cycling.
Được đề xuất
White Goods and Home Appliances
Washing machines, dishwashers and induction cooktops need 5V noise tolerance and long-life EEPROM for cycle calibration - exactly the PIC18F26Q10-E/SP use case. The CLCs combine multiple safety inputs (door-lock, water-level, NTC thermistor) into a single interrupt, simplifying IEC 60335 fault detection. The XLP sleep current keeps quiescent power below regulatory standby limits when the appliance is in idle mode between cycles.
Được đề xuất
Automotive Body and Lighting
Body control modules, LED drivers and ambient lighting benefit from the PIC18F26Q10-E/SP's LIN-capable UART, PWM-rich timer suite and 5V CAN-tolerant I/O. The CWG generates accurate 16-bit PWM dimming for RGB interior lighting while the HLT (Hardware Limit Timer) enforces watchdog-style safety timers for lamp-short detection. The -40C to +125C temperature grade covers under-hood and dashboard environments typical of automotive body electronics.
Được đề xuất
IoT Edge and Battery Metering
For battery-powered IoT edge nodes the PIC18F26Q10-E/SP combines XLP sleep currents in the sub-uA range with the 10-bit ADC2 to wake the CPU only on analog threshold crossings. The 64 KB Flash holds a small LoRaWAN or Bluetooth-Mesh stack plus application firmware, while the 256-byte EEPROM stores meter calibration across years of operation. The internal 64 MHz oscillator eliminates the external crystal in many metering designs, reducing BOM cost and PCB area.
Được đề xuất
Auxiliary SMPS and Power Conversion
In digital-assisted SMPS designs the PIC18F26Q10-E/SP acts as the housekeeping MCU: ADC2 samples primary-side voltage and current, the CWG outputs timing-critical gate-drive signals, and the ZCD synchronizes to mains frequency for valley-switching. The high-endurance Flash supports live firmware updates as the power supply vendor tunes its control loop. This companion-role MCU offloads housekeeping so a dedicated digital controller can focus on the switching loop itself.

Ghi chú thiết kế
Place the 0.1 uF VDD decoupling capacitor within 3 mm of the VDD pin (pin 19) and a bulk 10 uF tantalum or ceramic on the same rail. The 28-SPDIP pinout dedicates pin 8 to VSS; route a low-impedance ground pour directly under the part and stitch a ground via adjacent to pin 8 to keep digital switching noise away from the analog ADC2 inputs on RA0-RA5. Keep ADC traces short and guarded with VSS to preserve 10-bit ENOB.
The PIC18F26Q10-E/SP uses Peripheral Pin Select (PPS): peripherals such as UART, SPI and CCP default to specific pins after reset, but the firmware MUST call PPS_unlock and PPS_remap before relying on any remapped function. Omitting PPS configuration is a common first-programming failure mode on the Q10 family. Enable the WWDT with a window < counter value to detect runaway code in safety-relevant applications.
The PIC18F26Q10-E/SP itself dissipates only tens of milliwatts in typical embedded applications, but in BLDC and SMPS boards the adjacent gate drivers and power MOSFETs raise ambient temperature near the SPDIP package. Verify the E-grade 125C ceiling against worst-case ambient plus self-heating. For SPDIP through-hole designs, use wide PCB copper around the GND pins to conduct heat into the inner plane and keep the junction below 95% of the 125C limit in industrial testing.
