PIC18F26Q10-E/SS - 64KB Flash 8-bit MCU, 64MHz, 28-SSOP | Microchip
MPN: PIC18F26Q10-E/SS ✓ Hoạt độngPIC18F26Q10-E/SS Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals around an 8-bit data path. The PIC18 architecture is an enhanced 8-bit Harvard RISC core with 16-bit instructions, sitting within the broader hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor. PIC18 "XLP" parts target ultra-low-power designs, and the PIC18F26Q10 is part of Microchip's Functional Safety (FuSa) capable family with built-in CRC/SCAN for IEC 61508 SIL-aware designs.
Key features include 25 general-purpose I/O pins, two 16-bit timers, configurable logic cells for custom hardware glue, zero-cross detect, and on-chip temperature indicator. The device supports 1.8V to 5.5V operation, providing flexibility across 3.3V and 5V rails common in industrial and consumer designs. The 28-SSOP package offers a compact, surface-mount form factor with a standard 0.65mm pin pitch.
Typical applications include industrial control loops, IoT sensor nodes, touch-sensing front-ends, automotive body/comfort modules, and low-power battery-driven edge devices. The 5V tolerant I/O and integrated analog simplify designs that interface with legacy 5V sensors and actuators.
When designing with this MCU, plan oscillator and ICSP layout to keep the ICSPDAT/ICSPCLK traces short, and verify CRC/SCAN configuration in MPLAB X Code Configurator (MCC) before code freeze for functional safety projects. The device supports in-circuit serial programming (ICSP) and debugging via Microchip's ICD tools.

Ứng dụng tiêu biểu
PIC18F26Q10-E/SS phù hợp cho 8 Áp dụngs: Industrial Sensor Node with 5V Noise Immunity, IoT Edge Device with Battery Operation, Automotive Body and Comfort Module, Touch Sensing Front-End (mTouch), Functional Safety Diagnostic Controller, Low-Cost Motor and Lighting PWM Controller, Consumer Appliance User Interface, Data Logging and Edge Analytics Module.
Industrial Sensor Node with 5V Noise Immunity
The PIC18F26Q10-E/SS is well suited for industrial sensor nodes because it operates from 1.8 V to 5.5 V and provides 5 V tolerant I/O that resists the noise induced by long cable runs in factory environments. Its 64 KB Flash and 4 KB SRAM comfortably fit sensor conditioning firmware plus a small RTOS or state-machine scheduler. The integrated 10-bit ADC2 with computation offloads averaging and threshold detection from the CPU. SCAN/CRC peripherals enable Class B diagnostic routines common in industrial control cabinets.

IoT Edge Device with Battery Operation
The PIC18 XLP (eXtreme Low Power) variants of the PIC18F26Q10-E/SS support nanoWatt sleep currents below 1 uA, making the device appropriate for battery-driven IoT edge nodes that wake on sensor events. The extended -40 C to +125 C temperature grade allows deployment in outdoor enclosures. CLCs let designers build hardware wake-up logic without CPU intervention. The 64 KB Flash is large enough for an MQTT-SN or CoAP stack plus application code.
Được đề xuất
Automotive Body and Comfort Module
Although the PIC18F26Q10-E/SS is not AEC-Q100 qualified, designers use the E/SS variant (extended temperature grade) in non-safety automotive body modules such as interior lighting, mirror controllers, and accessory hubs. The 5 V operation matches legacy automotive bus rails, and the CWG peripheral simplifies half-bridge driving of small solenoids. Designers targeting safety-relevant functions should still select the AEC-Q100 qualified PIC18F46Q10 family.
Được đề xuất
Touch Sensing Front-End (mTouch)
Microchip's mTouch capacitive touch library runs natively on the PIC18F26Q10-E/SS, leveraging the ADC2 and CTMU peripherals to detect proximity and button presses through glass or plastic overlays. The 64 MHz core comfortably services 8 to 12 touch channels in parallel, and the CLC can debounce mechanical noise without CPU cycles. The extended temperature grade ensures reliable touch performance in cold outdoor installations.
Được đề xuất
Functional Safety Diagnostic Controller
The PIC18F26Q10-E/SS ships with hardware SCAN and CRC peripherals that support Class B and IEC 61508 diagnostic routines, enabling the MCU to monitor its own flash and SRAM for soft errors at runtime. Designers building safety-aware motor controllers, gas detectors, or appliance interlocks use these peripherals to reduce firmware overhead. The WWDT and HLT add windowed watchdog and hardware limit timing for fail-safe shutdown paths.
Được đề xuất
Low-Cost Motor and Lighting PWM Controller
The PIC18F26Q10-E/SS integrates multiple PWM channels, a Complementary Waveform Generator (CWG), and configurable logic cells that together can drive small DC fans, LED strips, or solid-state relays without external logic. The 64 MHz core and 16-bit timers deliver fine PWM resolution suitable for color-mixing LED drivers. The E temperature grade supports under-hood or enclosed-lighting environments.
Được đề xuất
Consumer Appliance User Interface
Consumer appliances such as coffee machines, washing machines, and air purifiers benefit from the PIC18F26Q10-E/SS's combination of 5 V tolerance, integrated ADC2 for sensor inputs, and CLCs for hardware button decoding. The 64 KB Flash accommodates a graphical or segment-LED user interface plus the appliance state machine. SCAN/CRC diagnostics give OEMs confidence in long-life products where field service is expensive.
Được đề xuất
Data Logging and Edge Analytics Module
The PIC18F26Q10-E/SS is well suited as the host in compact data loggers and edge analytics modules that sample analog signals, store them to external EEPROM or SD cards, and run lightweight analytics before forwarding to a gateway. The 4 KB SRAM supports a small ring buffer, while 64 KB Flash holds a C-coded analytics stack. The HLT and SCAN/CRC peripherals assist in verifying log integrity for regulated industries.

Ghi chú thiết kế
Place a 100 nF decoupling capacitor as close as possible to each VDD/VSS pin pair on the PIC18F26Q10-E/SS, plus a bulk 10 uF tantalum or ceramic on the main supply rail. Microchip's PIC18 datasheets recommend a 1 uF to 10 uF bulk cap on VDD to handle the inrush when internal voltage regulators wake from Sleep mode. The device supports 1.8 V to 5.5 V operation, so choose a regulator with adequate headroom and low quiescent current if Sleep-mode nanoamp performance is critical for battery life.
Route the ICSPDAT (RA0) and ICSPCLK (RA1) traces as short as possible and keep them away from switching signals such as PWM outputs on the CWG. If the PCB exposes an ICSP header, add ESD protection diodes on these lines and a series resistor near the MCU pin to limit programming inrush. Decoupling capacitors must use short, wide traces to the VDD/VSS pins, and the exposed pad on packages that have one (not applicable to the SSOP) should be soldered to a copper pour tied to VSS.
Do not assume the PIC18F26Q10-E/SS is AEC-Q100 qualified - it is industrial/extended grade. For automotive safety-relevant designs, choose the PIC18F46Q10-I/PT or another AEC-Q100 part. Also verify that the MCLR pin (if used) has a proper rise-time; Microchip recommends a 10 kohm pull-up plus a 100 nF cap to VDD to avoid spurious resets. Finally, when migrating from PIC18F25Q10 to PIC18F26Q10, double-check that your linker script accounts for the 64 KB Flash vs 32 KB Flash difference.
At 64 MHz the PIC18F26Q10-E/SS draws roughly 10 to 15 mA active current at 5 V (estimated for typical room-temperature CMOS IO loading, not a datasheet figure). The 28-SSOP package has modest thermal resistance and is typically adequate for industrial control boards without external heatsinking. Designers should still verify the operating current under worst-case peripheral activity (ADC2 continuous sampling, all I/O driving) and ensure the supply regulator can sustain peak demand without droop.
