PIC18F6628-E/PT - 8-Bit 25MHz 96KB Flash MCU | Microchip
MPN: PIC18F6628-E/PT ✓ Hoạt độngPIC18F6628-E/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, program and data memory, peripherals, and I/O onto one silicon die. The PIC18F family sits in Microchip's 8-bit hierarchy above baseline PIC10/12/16 families and below the 16-bit dsPIC and 32-bit SAM ARM Cortex-M lines, balancing low power consumption, deterministic interrupt latency, and rich peripheral integration for cost-sensitive embedded control.
Key specifications include a wide 4.2V to 5.5V supply range, 10-bit ADC up to 12 channels, 5 CCP/ECCP modules for PWM and motor control, parallel slave port for external bus expansion, hardware 8x8 multiplier, and nanoWatt power-saving modes. The 'E' suffix indicates the Extended (-40°C to +125°C) operating temperature grade suitable for harsh industrial environments. The -PT suffix denotes the TQFP-64 (10x10 mm) surface-mount package.
Architecturally, the PIC18F6628 uses a RISC Harvard architecture with separate program and data buses, a 16-bit instruction word, and a hardware multiply/divide unit delivering 25 MIPS at 25 MHz (40 MHz external oscillator with 4x PLL disabled). It supports ICD/ICSP in-circuit debugging and Flash self-programming via bootloader.
Typical applications include industrial automation controllers, automotive body and HVAC modules, building automation panels, LIN/J1939 networked sensors, graphical LCD user interfaces with touch, USB-to-UART bridges using external PHYs, and uninterruptible power supply monitors. The dual USART/LIN interface enables low-cost automotive body networks.
When designing with this part, leave ample ground copper and follow Microchip's TQFP-64 thermal pad recommendations even when the thermal pad is electrically floating, since reduced die-to-PCB thermal resistance aids power dissipation. Always configure unused I/O as outputs with logic-low to minimize current draw in standby, and reserve the ICSPDAT/ICSPCLK pins for in-circuit serial programming.

Ứng dụng tiêu biểu
PIC18F6628-E/PT phù hợp cho 7 Áp dụngs: Industrial Automation Controllers, Automotive Body and HVAC Modules, Graphical LCD User Interfaces, Uninterruptible Power Supply (UPS) Monitors, Building Automation Panels, Medical Monitoring Devices, USB-to-UART Bridge Modules.
Industrial Automation Controllers
The PIC18F6628-E/PT is well-suited for industrial PLCs, conveyor controllers, and sensor hubs where its 96KB Flash and 54 I/O pins handle multiple motor drivers and digital inputs. The Extended -40C to +125C temperature grade tolerates factory-floor thermal swings near motor enclosures. Its 25 MIPS performance executes PID loops and Modbus ASCII/RTU frames without an external DSP. NanoWatt sleep modes drop quiescent current below 100 nA in standby for energy-conscious field installations.

Ghi chú thiết kế
The PIC18F6628-E/PT operates from 4.2V to 5.5V. Provide at least 100 nF decoupling on each VDD/VSS pair (pins 18/19, 28/29, 39/48) placed within 5 mm of the pin, plus a bulk 10 uF tantalum near the supply entry. Add a 10 kohm pull-up to VDD on the MCLR pin (pin 5) with a series diode to VDD for protection against ESD-induced reset. Estimated: total decoupling ESR budget should remain below 50 milliohm at the switching frequencies used by the on-chip PLL.
The 64-pin TQFP (10x10 mm) has a 0.5 mm pitch and 0.6 mm pad width. Use NSMD land pads 0.4 mm wide with 0.2 mm solder mask expansion. Route signals on inner layers first to escape the dense perimeter; keep traces 0.15 mm or wider to maintain 50-ohm impedance if controlled-impedance routing is needed. The exposed die attach pad (if present in this package variant) should be soldered to a 7 mm x 7 mm copper island for thermal dissipation even though it is electrically floating per the datasheet.
Do not enable low-voltage ICSP (LVP) via the LVP_CONFIG fuse unless pin RB5 is dedicated to programming; otherwise the device may fail to start in noisy environments. Configure all unused I/O as outputs driving low to minimize current draw in sleep mode. Always read the configuration bits with the right ID mask - PIC18F6628 and PIC18F6627 have similar device IDs but different peripheral disable masks. When migrating firmware between F6628 and F6627, re-verify ADC channel mappings for AN6-AN12.
