PIC18F67J60-I/PT - 8-bit MCU, 128KB Flash, 10BASE-T Ethernet | Microchip
MPN: PIC18F67J60-I/PT ✓ Hoạt độngPIC18F67J60-I/PT Tóm tắt
An 8-bit microcontroller is a single-chip processor with an 8-bit data path, on-chip Flash program memory, RAM, and integrated peripherals. It sits in the hierarchy: microcontroller -> embedded microprocessor -> integrated circuit -> semiconductor. The PIC18 family extends this with a RISC architecture, hardware multiply, and C-friendly peripherals, while the PIC18F67J60 sub-family adds an embedded Ethernet controller that integrates the MAC, PHY, and pulse transformers, making it a single-chip solution for networked embedded designs.
Key features include 128 KB Flash organized as 64K x 16 words, 12 KB SRAM, an integrated 10BASE-T Ethernet MAC/PHY with HP Auto-MDIX support, 54 digital I/O pins, two USARTs, two MSSP (SPI/I2C) ports, two CCP/ECCP modules, a 10-channel 10-bit ADC, and one 8-bit and three 16-bit timers. The Ethernet peripheral is the defining element: it eliminates the need for an external PHY or MAC chip, reducing BOM cost and PCB area in remote-monitoring nodes.
Internally, the part uses a Harvard RISC core with a hardware multiplier, runs from an internal 8 MHz oscillator (pll-able to 41.667 MHz), and supports in-circuit programming via ICSP. The Flash and configuration bits are accessed through Microchip's standard MPLAB development flow, and the on-chip Ethernet module uses an internal DMA engine to offload packet handling from the CPU.
Typical applications include Industrial Automation (Modbus/TCP nodes, sensor gateways), Building Automation (BACnet/IP thermostats, lighting controllers), Remote Monitoring (utility metering, asset tracking), Embedded Web Servers, and Home Appliance Networking. The wide 4.2 V to 5.5 V supply range also makes it tolerant of unregulated 5 V wall adapters.
When designing with this part, ensure the integrated Ethernet PHY is matched to a 1:1 isolation transformer and RJ45 with HP Auto-MDIX wiring to preserve the auto-crossover feature. The 64-pin TQFP footprint requires careful PCB routing of the differential Ethernet pair to maintain 100-ohm differential impedance over a continuous reference plane.

Industrial Automation Gateway
The PIC18F67J60-I/PT is well suited to industrial automation gateways such as Modbus/TCP nodes and sensor aggregation bridges. The integrated 10BASE-T MAC/PHY with HP Auto-MDIX eliminates the external Ethernet controller, reducing BOM and PCB area in DIN-rail enclosures. The 12 KB SRAM supports Microchip's TCP/IP Lite stack, while 128 KB of Flash accommodates protocol translation logic. The 54 digital I/O pins handle multiple sensor interfaces, and the -40C to +85C industrial range tolerates factory environments.

Ghi chú thiết kế
Route the integrated Ethernet differential pair (TP+/- on the chip pins) over a continuous ground reference plane with 100-ohm differential impedance. Keep the trace length under 50 mm and avoid splits in the ground plane beneath the pair to maintain signal integrity for 10BASE-T operation; place the 1:1 isolation transformer within 25 mm of the PHY pins.
Estimated: at 41.667 MHz and 5 V VDD with all peripherals enabled, the device typically draws ~70 mA. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of each VDD pin and a bulk 10 uF tantalum cap at the regulator output; the Ethernet PHY benefits from an additional 10 uF + 100 nF LC filter near the analog supply pin to suppress switching noise coupling into the line drivers.
The 'J' in PIC18F67J60 indicates a 5V-tolerant I/O design that cannot operate below 4.2 V - connecting this part to a 3.3 V rail will result in undefined oscillator behavior. Do not substitute a PIC18F67J10 design without re-validating the supply and crystal circuit. Also ensure the CONFIG bits set the correct oscillator mode and disable the JTAG pins if not used, otherwise PORTB will be unavailable.
Thông tin tuân thủ
