PIC18F87J10-I/PT Übersicht
An 8-bit MCU is a microcontroller whose central processing unit processes data in 8-bit chunks; the PIC18 family uses an enhanced RISC architecture with a modified Harvard memory layout that separates program and data buses, which accelerates instruction fetch and execution. The 'J' designation indicates the device operates from a 2.0-3.6 V supply and is designed for cost-sensitive embedded designs with rich peripheral integration including USB 2.0 full-speed, two I2C/SPI, two USART (LIN-capable), and a 10-bit A/D converter.
Key features include 128 KB Flash (64K x 16), 4 KB SRAM, two I2C, two SPI, two USART with LIN support, USB 2.0 full-speed on-chip transceiver, 10-bit ADC with up to ten channels, two analog comparators, a 16-bit timer and three 8-bit timers, and a parallel slave port for external memory or graphics interfaces. Industrial operating range is -40C to +85C.
The device is built on an enhanced PIC18 CPU core using a single 3.3 V supply, eliminating the legacy dual-rail (5 V core / 3.3 V I/O) complexity of earlier PIC18F parts. This single-rail architecture simplifies power-tree design and is ideal for cost-constrained applications that previously required external level translation.
Typical applications include USB peripherals, embedded control with LIN/UART bridging, industrial sensor nodes, human-interface displays, and cost-sensitive consumer electronics. The 80-pin TQFP package provides generous I/O (>60 I/O pins) suitable for color graphics TFT panels and parallel-bus peripherals.
When designing with this MCU, note the 2.0-3.6 V supply constraint and ensure upstream regulators deliver clean 3.3 V. The PT suffix denotes the industrial temperature grade (-40C to +85C) in the 80-pin TQFP package.

Wichtigste Unterscheidungsmerkmale
- Single 3.3 V supply simplifies power tree vs dual-rail PIC18F8722 (vs. PIC18F8722-I/PT)
- Larger Flash (128 KB vs 64 KB) for richer USB applications (vs. PIC18F86J10-I/PT)
- Industrial temperature grade in active production (vs. PIC18F8722-I/PT)
Designhinweise
The PIC18F87J10-I/PT requires a single 2.0-3.6 V supply, typically regulated from a 5 V USB rail via a 3.3 V LDO such as MCP1700. Place 100 nF decoupling capacitors as close as possible to every VDD/VSS pair (typically 6 pairs on this package) and add a bulk 4.7-10 uF tantalum or ceramic at the regulator output. The VUSB pin (pin 30) is internally powered from the USB transceiver regulator and requires its own 100 nF decoupling capacitor per the Microchip datasheet. Avoid long trace lengths between the regulator output and the MCU VDD pins.
Route the USB D+ and D- lines (pins 78-79) as a 90-ohm differential pair with matched length, keeping them short and isolated from switching signals. Place the ICSP pins (RB6/RB7 = pins 18-19) on a debug header so the PICkit programmer can attach in-circuit. Expose the MCLR pin (pin 1) with a pull-up resistor (typically 10 kohm) and a 100 nF cap to ground for clean reset behaviour. For TQFP-80 layout, fan-out VDD/VSS pairs to a solid ground pour and use a 4-layer PCB with continuous power plane.
Do not exceed the 3.6 V maximum on VDD - although PIC18F87J10 has 5 V tolerant features on legacy parts, the J-series is strictly 3.3 V. When migrating from PIC18F8722 (dual rail), confirm that no peripheral pin is driven above 3.6 V during transitions. Always include proper ESD protection on USB D+/D- lines and on any externally-accessible connector. Configure the internal USB regulator correctly per the datasheet's 'USB' chapter; failure to enable VUSB capacitor will cause USB enumeration failures.
When using the Parallel Master Port (PMP) to drive a TFT display, place 33 ohm damping resistors in series with the 8-bit data bus and control lines to reduce ringing. Keep trace impedance controlled at 50 ohms for clean edges. Use series source termination for clock signals above 20 MHz. For USB signals, ensure D+/D- have 90-ohm differential impedance and that the trace length difference is < 150 mil to avoid skew.
