MPN: PIC18F24Q10T-I/SS ✓ Hoạt độngPIC18F24Q10T-I/SS Tóm tắt
The PIC18F24Q10 belongs to the PIC® XLP™ 18Q functional-safety family, an 8-bit microcontroller category that integrates CPU core, non-volatile Flash, SRAM, EEPROM, and peripherals into a single CMOS die. Within the broader PIC18 family, the 'Q10' sub-series adds Core Independent Peripherals (CIPs) that offload tasks such as signal conditioning, waveform generation, and timing from the CPU, enabling deterministic real-time response at very low power. The 'XLP' designation indicates eXtreme Low Power operation, supporting battery-powered and energy-harvesting applications. PIC18 microcontrollers occupy the 8-bit MCU tier of the embedded market and target cost-sensitive designs where determinism, low power, and integrated analog matter more than raw compute throughput.
Key features include 16 KB self-programmable Flash, 2 KB SRAM, 256 bytes EEPROM, a 10-bit ADCC with up to 25 analog channels, a 5-bit DAC, two comparators with selectable hysteresis, a 16-bit PWM with four modes, a windowed watchdog timer for functional safety, and serial connectivity via I2C, SPI, and UART/USART. The device operates from 1.8V to 5.5V, making it compatible with both 3.3V and 5V rails common in industrial and consumer designs.
The 64 MHz internal oscillator, peripheral pin-select (PPS) routing, and CIP blocks allow the device to handle sensor conditioning, closed-loop control, and user-interface tasks in hardware. The ADCC automates averaging, threshold comparisons, and burst-mode sampling, offloading the CPU in high-noise industrial environments. XLP technology with nanoWatt XLP sleep currents enables years of operation from a coin cell.
Typical applications include industrial sensor nodes, home appliance control, IoT edge devices, automotive body electronics, motor control for small BLDC and stepper fans, LED lighting controllers, and battery-powered metering. The functional-safety (FuSa) features also make it suitable for safety-critical IEC 61508 SIL-2 designs.
When designing with this part, observe VDD decoupling guidance (100 nF + bulk) and route ICPGD/ICPCK for in-circuit programming. The 28-SSOP footprint is shared across the PIC18F24Q10 family, allowing easy migration to PIC18F25Q10 (32 KB Flash) or PIC18F26Q10 (64 KB Flash) without PCB rework.

Ứng dụng tiêu biểu
PIC18F24Q10T-I/SS phù hợp cho 8 Áp dụngs: Industrial Sensor Nodes, Home Appliance Control, IoT Edge Devices, Automotive Body Electronics, Small Motor Control (BLDC, Stepper, Fan), LED Lighting Controllers, Battery-Powered Metering, Functional Safety (FuSa) Embedded Control.
Industrial Sensor Nodes
The PIC18F24Q10T-I/SS is purpose-built for industrial sensor nodes that read analog signals and forward them over RS-485/I2C/SPI. Its 10-bit ADCC with computation offloads averaging, threshold detection, and burst-mode sampling from the CPU, allowing the 64 MHz core to spend most of its time in XLP sleep with nanoWatt currents. The 1.8V-5.5V supply range accommodates 3.3V and 5V PLC rails, while the WWDT and brown-out reset support IEC 61508 SIL-2 functional-safety designs.
Được đề xuất
Home Appliance Control
The PIC18F24Q10T-I/SS drives control panels and motor interfaces in washing machines, dishwashers, and HVAC actuators. The 16-bit PWM with four modes plus the 5-bit DAC and two comparators generate variable-frequency drives for small BLDC and shaded-pole motors. The 25 I/O pins route keypad, LED status indicators, triac interfaces, and an I2C/SPI EEPROM without external logic. Internal 64 MHz oscillator eliminates an external crystal in most appliance designs.
Được đề xuất
IoT Edge Devices
The PIC18F24Q10T-I/SS anchors IoT edge nodes that combine sensing, local decision-making, and low-rate wireless transmission. Its XLP nanoWatt sleep modes enable years of battery life on a single CR2032, while the on-chip ADCC and comparators wake the device only on threshold events (CIP). The I2C/SPI/UART interfaces connect to popular sub-GHz transceivers (LoRa, Sigfox, NB-IoT) without external logic, and the 2 KB SRAM supports modest protocol stacks and ring buffers.
Được đề xuất
Automotive Body Electronics
The PIC18F24Q10T-I/SS suits body-electronics modules - lighting controllers, seat controls, mirror actuators, and HVAC blend doors - that operate directly from the 12V battery rail via local regulation. Its industrial -40C to +85C temperature range covers cabin environments, while the WWDT and FuSa features support ASIL-A decompositions of body-domain ECUs. The 16-bit PWM drives LED arrays with smooth dimming, and the 5-bit DAC provides analog setpoint outputs to motor drivers.
Được đề xuất
Small Motor Control (BLDC, Stepper, Fan)
The PIC18F24Q10T-I/SS controls small BLDC and stepper motors used in PC fans, drone ESCs, and small appliance pumps. The 16-bit PWM with complementary outputs plus dead-band control drives half-bridges via gate drivers, while the QEI (Quadrature Encoder Interface) CIP decodes Hall-sensor or encoder feedback at high speed. The CIP-based waveform generation offloads commutation from the CPU, leaving 50%+ MIPS free for the application layer.
Được đề xuất
LED Lighting Controllers
The PIC18F24Q10T-I/SS drives multi-channel LED controllers and tunable-white fixtures. The 16-bit PWM offers flicker-free dimming down to 0.1% duty cycle, while the 10-bit ADCC reads ambient light sensors and current-sense amplifiers for closed-loop brightness control. The I2C bus interfaces to off-the-shelf LED drivers (LP8860, TLC59401) and DMX gateways, and the 2 KB SRAM supports effect sequencers and color-space conversions.
Được đề xuất
Battery-Powered Metering
The PIC18F24Q10T-I/SS is well suited to battery-powered metering (gas, water, heat, electricity sub-metering) that must run 10+ years from a primary cell. The XLP nanoWatt sleep currents drop below 100 nA with the RTC and WWDT active, while the 10-bit ADCC samples sensor pulses on interrupt-driven wakes. The 256-byte EEPROM retains calibration constants and tamper flags without external memory, and the wide 1.8V-5.5V supply range tolerates lithium-thionyl chloride discharge curves.
Được đề xuất
Functional Safety (FuSa) Embedded Control
The PIC18F24Q10T-I/SS is part of Microchip's Functional Safety (FuSa) portfolio and is supported by safety manuals, FMEDA reports, and diagnostic libraries targeting IEC 61508 SIL-2 designs. The WWDT, brown-out reset, ECC on Flash, and CRC peripheral provide hardware-level fault detection that, combined with the CIP-based deterministic response, reduce software diagnostic overhead. The 28-SSOP footprint simplifies retrofit into existing safety-certified designs that already use a PIC18 in the same package.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 11) and a bulk capacitor (10 uF or larger) within 1 cm. The PIC18F24Q10T-I/SS draws fast switching transients during 64 MHz operation; inadequate decoupling can cause spurious reset events. For battery applications, add a 1 MOhm resistor from MCLR to VDD to enable the internal pull-up and prevent false resets during voltage transients.
The 28-SSOP package uses 0.65 mm pitch and 0.3 mm wide leads. Use a reflow profile consistent with JEDEC J-STD-020 MSL-2. Route ICSP lines (ICPCK/ICSPDAT) on the same PCB layer as the MCU with no vias if possible, and add 4.7 kOhm pull-ups to VDD on both lines. Keep analog signals (AN0-AN13) away from PWM and switching traces to minimize coupled noise.
Do not confuse the 28-SSOP pinout with the 28-SOIC or 28-QFN package - the SSOP-28 and SOIC-28 pinouts are NOT identical on all PIC18 variants. Verify against the DS40001971 datasheet pinout before laying out your PCB. Also, the 'T' suffix denotes Tape & Reel (2,100 per reel); prototypes without 'T' ship in tubes. Programming via ICSP requires MCLR to be free - do not pull MCLR high with a capacitor.
Estimated: At maximum CPU activity (64 MHz, all peripherals enabled, all I/O switching), the PIC18F24Q10T-I/SS typically draws ~30 mA at 5V, dissipating ~150 mW. The 28-SSOP package theta_JA is approximately 80 C/W in still air, giving a junction-temperature rise of 12 C above ambient at full load - no heatsink needed. For industrial temperature-grade parts (-40C to +85C), verify derating at the 85C boundary.
Thông tin tuân thủ
RoHS and REACH compliant per Microchip product page. The 'T-I' suffix indicates industrial temperature grade (-40C to +85C) but NOT AEC-Q100. For automotive-grade equivalent, use the PIC18F24Q10T-I/SSVAO part number with AEC-Q100 qualification. Functional Safety (FuSa) documentation per IEC 61508 SIL-2 available from Microchip.
