PIC18LF6627-I/PT - 8-Bit 40MHz MCU 96KB Flash 64-TQFP | Microchip
MPN: PIC18LF6627-I/PT ✓ Hoạt độngPIC18LF6627-I/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals into one IC. Within the broader taxonomy, a microcontroller belongs to the integrated circuit family, sits alongside microprocessors, DSPs, and FPGAs, and is the lowest-power member of the programmable-logic hierarchy used for embedded control. The PIC18F sub-family adds hardware multipliers, multiple interrupt priority levels, and C-friendly architecture on top of the original PIC16 baseline.
Key differentiating specifications include 96 KB Flash with self-programmability, 1 KB of EEPROM data memory, 12 channels of 10-bit ADC, up to five 16-bit timers/counters, two enhanced USART modules, two MSSP (SPI/I2C) peripherals, an integrated ECAN controller, dual analog comparators, and nanoWatt XLP sleep currents below 100 nA. The 64-pin TQFP gives engineers enough GPIO and peripheral pin-out for medium-complexity human-interface, sensor-fusion, and CAN-connected designs.
The PIC18LF6627 uses Microchip's enhanced Harvard RISC core with a 16-bit instruction word, hardware multiply, and a 31-level hardware stack. The 'LF' suffix designates the low-voltage F-variant that supports 2.0 V operation, distinguishing it from the standard PIC18F6627 that runs from 4.2 V to 5.5 V. Code developed for the PIC18F6627 is generally portable to the LF version as long as VDD stays inside the LF mask window.
Typical applications include industrial CAN nodes, HVAC and building-automation controllers, automotive body-comfort modules, low-power sensor hubs, USB-to-CAN bridges, and portable instrumentation where extended battery life matters. Engineers frequently select this part for designs that need ECAN, multiple serial interfaces, and analog sensing in a single chip.
When designing with this part, reserve the MCLR pin for an external pull-up and decoupling, provide a bulk + 100 nF pair on VDD/VSS, and follow Microchip's emulator header pinout if in-circuit debug is required. Also ensure your firmware linker script matches the 48K-word Flash boundary to avoid placement errors during build.

Ứng dụng tiêu biểu
PIC18LF6627-I/PT phù hợp cho 6 Áp dụngs: Industrial CAN Nodes, HVAC and Building Automation Controllers, Automotive Body Comfort Modules, Low-Power Sensor Hubs, USB-to-CAN Bridge Modules, Portable Instrumentation and Data Loggers.
Industrial CAN Nodes
The PIC18LF6627-I/PT's on-chip Enhanced CAN (ECAN) controller makes it well-suited for industrial CAN bus nodes such as motor controllers, valve actuators, and distributed I/O modules. With 96 KB Flash, 4 KB RAM, and 70 I/O pins, the device can host a complete CANopen or DeviceNet slave stack while still leaving room for application-specific logic. The 2.0-5.5 V supply range allows the part to be powered directly from 24 V industrial buses after regulation, simplifying bill of materials. Pairing it with an external MCP2562 CAN transceiver creates a robust, isolated-capable node with deterministic CAN 2.0B communication at 1 Mbit/s.

HVAC and Building Automation Controllers
The PIC18LF6627-I/PT fits building automation controllers that need to aggregate temperature, humidity, and air-quality sensors through its 12-channel 10-bit ADC, then communicate over RS-485 or CAN to a central BMS. Its 96 KB Flash can host a complete BACnet MS/TP or Modbus slave stack, while the 4 KB RAM supports real-time scheduling tables. nanoWatt XLP sleep currents below 1 uA in deep sleep enable battery-backed thermostats that run for years on a single CR2032. The dual MSSP peripherals allow simultaneous SPI sensor and I2C RTC connectivity without an external multiplexer.
Được đề xuất
Automotive Body Comfort Modules
The PIC18LF6627-I/PT is used in body-comfort automotive subsystems such as seat controllers, mirror adjusters, and lighting modules where moderate Flash and CAN connectivity are required. The integrated ECAN controller connects directly to vehicle body networks, while the 12-bit ADC and dual analog comparators handle window-current sensing and lamp-bulb health monitoring. The industrial -40 C to +85 C temperature rating covers most cabin environments. For under-hood applications, however, designers should migrate to AEC-Q100-qualified PIC18 variants such as the PIC18F46K80-I/PT family to meet automotive reliability targets.
Được đề xuất
Low-Power Sensor Hubs
Battery-powered sensor hubs leverage the PIC18LF6627-I/PT's nanoWatt XLP technology and 2.0 V minimum supply to run years on a single AA cell. The 12-channel ADC can read multiple analog sensors simultaneously while the dual MSSP handles SPI environmental sensors and I2C displays. Sleep currents below 100 nA with RAM retention allow wake-on-interrupt from sensor triggers without external RTC chips. The 96 KB Flash stores sensor calibration tables and edge-processing algorithms on-device, reducing wireless traffic and cloud-billing costs.
Được đề xuất
USB-to-CAN Bridge Modules
Engineers building USB-to-CAN bridges, automotive diagnostic dongles, or industrial protocol converters benefit from the PIC18LF6627-I/PT's combination of ECAN and dual enhanced USART. The 96 KB Flash can host USB CDC plus CANopen, J1939, or DeviceNet stack layers, while the 4 KB RAM provides buffer headroom for high-throughput packet forwarding. Industrial temperature rating allows the module to operate reliably in enclosure-mounted installations. For lower-cost bridges, the smaller-pin PIC18LF46K80T-I/PT family may be evaluated.
Được đề xuất
Portable Instrumentation and Data Loggers
Portable data loggers and field-instrumentation devices use the PIC18LF6627-I/PT because it integrates ADC, multiple serial interfaces, and large Flash in a single chip. The 1 KB EEPROM is ideal for non-volatile configuration storage that survives battery swaps, while the 96 KB Flash supports weeks of buffered measurement data. The industrial temperature range allows operation in outdoor enclosures, and the 2.0 V minimum VDD supports direct lithium primary-cell operation. CTMU-based capacitive touch support enables rugged front-panel buttons without mechanical switches.

Ghi chú thiết kế
Estimated: at 5 V VDD, 40 MHz CPU, full peripheral activity, the PIC18LF6627-I/PT draws approximately 15 mA, giving power dissipation of about 75 mW. The 64-pin TQFP exposes the thermal pad (pin 64 area) for board-level cooling, but at this power level a 4-layer PCB with a ground plane is more than adequate. Designers targeting nanoWatt XLP deep-sleep should configure the part in Sleep mode with peripherals disabled; typical deep-sleep current is below 100 nA per Microchip datasheet. Decouple each VDD/VSS pair with 100 nF X7R placed within 5 mm of the pins.
Place the MCLR pull-up (typically 10 kohm) close to the pin and route the ICSP PGC/PGD traces together without stubs to maintain signal integrity during programming. Keep the crystal traces short and surround them with a ground guard ring to avoid injecting oscillator noise into the analog inputs. Use a 4-layer PCB with a continuous ground plane for designs that rely on the 12-bit ADC performance, and place the AVSS pin directly to the analog ground plane if separating analog and digital grounds.
Do not confuse the LF (2.0-5.5 V) variant with the standard F (4.2-5.5 V) variant when designing at 3.3 V - only LF parts operate reliably across the full 2.0-5.5 V range. When migrating from PIC18F6627 to PIC18LF6627 firmware, verify that the configuration bits for oscillator mode and brown-out voltage remain within the LF datasheet limits. Also confirm the linker script places code within the 48K-word Flash boundary; firmware built for a 64 KB device will not run on this 96 KB part without verification of the linker memmap.
The ECAN controller on the PIC18LF6627-I/PT requires a high-speed CAN transceiver on the bus side such as the MCP2551 or MCP2562. Without a transceiver, the ECAN pins cannot drive the differential bus directly. For systems exposed to ESD or surge events (industrial and automotive), add TVS protection such as the PESD1CAN on the bus lines and common-mode chokes to meet IEC 61000-4-2 transient immunity requirements. Configure the ECAN baud rate and propagation segment timing per the CiA 601 CAN bit-time recommendations for reliable 1 Mbit/s operation.
