PIC18F86J60T-I/PT - 8-Bit MCU with 10BASE-T Ethernet 64KB Flash | Microchip
MPN: PIC18F86J60T-I/PT ✓ Hoạt độngPIC18F86J60T-I/PT Tóm tắt
A PIC18 microcontroller is a high-performance 8-bit RISC MCU in Microchip's PIC family, supporting 16-bit opcodes and an enhanced instruction set with hardware multiply. The PIC18F86J60 belongs to the PIC18J sub-family, characterized by nanoWatt technology for low-power operation and integrated peripherals targeted at networked embedded designs. The on-chip Ethernet controller eliminates the need for an external MAC chip, simplifying connectivity for industrial automation, building automation, and remote monitoring designs.
Key specifications include 64KB Flash program memory, 12KB SRAM, a 10BASE-T Ethernet MAC/PHY, an internal 31 kHz to 8 MHz oscillator, nanoWatt power management with multiple idle and sleep modes, a 10-bit ADC with up to 16 channels, two analog comparators, two CCP modules, an Enhanced USART, and an MSSP I2C/SPI port. The suffix T-I/PT indicates tape-and-reel packaging, industrial temperature range (-40C to +85C), and the 80-pin TQFP form factor.
Designed with a 5-stage pipeline and Harvard architecture, the PIC18F86J60 executes most instructions in a single 4-cycle tick at 83.33 MHz internal frequency derived from a 10 MHz crystal (or 41.667 MIPS). Integrated nanoWatt Technology allows dynamic clock switching and idle/doze modes that lower current draw during idle periods - critical for always-on networked sensor nodes.
Typical applications include industrial automation controllers with Ethernet connectivity, building automation thermostats and lighting controllers, remote monitoring data loggers with web server firmware, HVAC networking nodes, and IP-enabled sensor hubs. The integrated Ethernet MAC/PHY supports the full 10BASE-T physical layer for 10Mbps half-duplex operation, eliminating BOM cost in cost-sensitive designs.
When designing with this part, ensure the analog and digital supply pins each have local 0.1uF decoupling placed within 5 mm of the pin, the 25 MHz Ethernet reference clock is provided through a proper crystal, and the 49.9 ohm Ethernet magnetics match the on-chip PHY. The 80-TQFP footprint allows conventional PCB manufacturing with standard 0.5 mm pitch leaded packages.

Ứng dụng tiêu biểu
PIC18F86J60T-I/PT phù hợp cho 6 Áp dụngs: Industrial Automation Controllers, Building Automation Thermostats, Remote Monitoring Data Loggers, HVAC Networking Nodes, IP-Enabled Sensor Hubs, Lighting Control Systems.
Industrial Automation Controllers
The PIC18F86J60T-I/PT's integrated 10BASE-T MAC/PHY and 41.667 MHz CPU make it ideal for industrial PLCs, motor controllers, and factory sensor nodes that need network connectivity without external PHY chips. The 12KB SRAM accommodates Modbus/TCP and lightweight HTTP servers, while 64KB Flash holds protocol and user logic. The 80-TQFP exposes up to 70 I/O lines, enough to drive multiple relay outputs and sense analog inputs from a 10-bit ADC with 16 channels. Industrial -40C to +85C operation survives panel-mounted cabinets.
Được đề xuất
Building Automation Thermostats
The PIC18F86J60T-I/PT serves as the networked brain of HVAC thermostats by serving HTML configuration pages over HTTP via the on-chip 10BASE-T PHY. Its nanoWatt Technology idle and sleep modes drop current draw during display-off hours, suiting battery-backup thermostats that must remain network-connected during power blips. The 10-bit ADC scans thermistor and humidity inputs, while the EUSART drives the LCD controller for room-temperature feedback. The -40C to +85C industrial range survives plenum mounting.
Được đề xuất
Remote Monitoring Data Loggers
The PIC18F86J60T-I/PT is purpose-built for IP-enabled data loggers that periodically POST telemetry to cloud servers via HTTP. The 12KB SRAM buffers queued measurements during network reconnection events, while 64KB Flash runs Microchip's TCP/IP MLA stack and user firmware. With 41.667 MHz CPU, the MCU handles JSON serialization, AES-128 encryption for cloud APIs, and timestamp stamping of every measurement. The 80-TQFP leaves room for SD-card interfaces, real-time clocks, and external FRAM logging.
Được đề xuất
HVAC Networking Nodes
The PIC18F86J60T-I/PT powers BACnet/IP or Modbus TCP nodes on commercial HVAC systems where each rooftop unit reports status back to a building management system over 10BASE-T. Its 41.667 MHz CPU runs the BACnet stack alongside damper and fan-control firmware. The 80-TQFP exposes enough I/O to read multiple 4-20 mA current loops for CO2 and occupancy sensors, plus drive triac outputs for compressor and fan contactors. nanoWatt Technology reduces standby draw during occupied/unoccupied mode transitions.
Được đề xuất
IP-Enabled Sensor Hubs
The PIC18F86J60T-I/PT acts as a multi-sensor aggregator that publishes JSON or CSV readings from humidity, temperature, CO2, and light sensors to network dashboards every 10 seconds via HTTP or CoAP. The integrated 10BASE-T MAC/PHY removes the need for external Ethernet controllers, reducing BOM cost. EUSART plus MSSP drive multiple sensor buses (RS-485 Modbus and SPI/I2C peripherals) simultaneously, while the 10-bit ADC channels scan analog front-ends for current-loop sensors in industrial installations.
Được đề xuất
Lighting Control Systems
The PIC18F86J60T-I/PT drives networked DALI or 0-10V lighting controllers in commercial buildings. The 80-TQFP pin count allocates I/O for up to 16 dimming channels plus DMX-512 input and the on-chip 10BASE-T controller for backbone connectivity to BACnet gateways. Real-time response at 41.667 MHz handles fade curves, occupancy sensor input, and astronomical time-clock scheduling while serving HTML configuration pages for installers. nanoWatt Technology allows idle current draw under 5 uA for emergency lighting controllers.

Ghi chú thiết kế
Estimated: the PIC18F86J60T-I/PT dissipates approximately 300 mW at full CPU + Ethernet load with VDD = 3.3V and I/O switching. Place a 100 nF decoupling capacitor within 5 mm of each VDD pin (11, 32, 61, 78) and a 10 uF bulk capacitor near the package. The ETH VDD pin (73) requires a dedicated 100 nF plus a ferrite bead to isolate the Ethernet PHY supply from digital switching noise. The analog AVD/AVSS pins (44/45) must have their own filtered supply through a ferrite bead plus 100 nF, with no digital return currents routing through AVSS - otherwise ADC readings drift by tens of counts.
The integrated 10BASE-T PHY is a 10 Mbps half-duplex-only interface; do NOT route it through standard 100 Mbps-only magnetics or through gigabit transformers - link will fail to come up. According to the Microchip datasheet, the 49.9 ohm RBIAS resistor on pin 70 must be 1% precision with a maximum 50 ppm/C temperature coefficient, or the PHY bias current drifts out of spec across temperature, causing intermittent link drops. Connect MCLR (pin 74) through a 10 kohm pull-up to VDD; do not leave it floating - the part will operate unreliably and ICSP programming will fail intermittently.
Keep the ETH TX+/TX- and RX+/RX- differential pairs matched within 2 mm of length mismatch and route them with 100 ohm differential impedance on the PCB; route them on the top layer with an unbroken ground plane beneath. Terminate the unused Ethernet pins with 75 ohm resistors to ground if not used (e.g., when disabling the MAC). Separate the analog AVSS return path from digital VSS by using a star ground at the MCU; otherwise the 10-bit ADC on-chip reference will be polluted by digital switching noise.
