Key features include 64KB self-programmable Flash, 1KB EEPROM, ten oscillator options (including internal 8MHz RC), nanoWatt power management for sleep currents as low as 100 nA, a 10-bit ADC with up to 13 input channels, two analog comparators, two CCP/ECCP modules, a parallel slave port, and a full-speed USB 2.0 full-speed (12 Mbps) transceiver on die. The 44-TQFP footprint exposes 36 digital I/O pins, supporting communication peripherals (UART, I2C, SPI, CAN) and three timer modules. Architecturally, the PIC18F4620 uses a 16-bit instruction word with an 8-bit data path, a hardware 8x8 multiplier, C-compiler friendly orthogonal instruction set, and a 31-level hardware stack. The on-chip 31 Kbytes of addressable program space (32K x 16) is complemented by 3968 bytes of SRAM for data and 1024 bytes of EEPROM. The integrated USB 2.0 FS transceiver eliminates external PHY cost for USB device designs. Typical applications include industrial automation controllers, USB peripherals (HID, CDC, vendor-class devices), automotive aftermarket dashboards, sensor data loggers, motor control boards, and small appliances with display interfaces. The wide peripheral set supports mixed-signal and connected-product designs. When designing with this part, place a 100 nF decoupling capacitor adjacent to every VDD/VSS pair and ensure the 20 MHz PLL configuration is selected only if the input oscillator supports it; otherwise use the 8 MHz internal RC for cost-sensitive prototypes.

It offers 36 digital I/O lines, a 10-bit A/D converter with up to 13 input channels, multiple serial peripherals (USART, MSSP for SPI/I2C), and nanoWatt power management for energy-efficient designs. A PIC18 microcontroller is an 8-bit RISC-architecture MCU from Microchip's PIC18 family that combines Harvard bus architecture with a 16-bit instruction word, sitting in the broader taxonomy of microcontroller -> embedded MCU -> 8-bit MCU -> CMOS flash MCU -> semiconductor. The PIC18F4620 sits at the upper end of the original PIC18F46xx family, providing more memory and I/O than the PIC18F4520 while sharing the same peripheral set for code reuse. Key features include 64 KB self-programmable Flash (32K x 16), 3968 bytes SRAM, 1024 bytes EEPROM, 40 MHz maximum clock (10 MIPS at 10 MHz / 40 MIPS at 40 MHz), 36 I/O pins with individual direction control, an Enhanced Capture/Compare/PWM (ECCP) module, two CCP modules, a 10-bit ADC with 13 channels and 100K samples/sec, two analog comparators, and a USART with RS-485 support. The 'T' suffix denotes tape-and-reel packaging, the 'I' indicates the -40C to +85C industrial temperature grade, and 'ML' specifies the 44-pin QFN. The PIC18F4620T-I/ML uses a modified Harvard architecture with separate program and data buses, a hardware multiplier for 8x8 single-cycle instructions, and nanoWatt technology that allows multiple power-managed modes (Idle, Sleep, Doze) for battery-powered and always-on applications. The wide 2.0V to 5.5V operating range (industrial grade, with F variant limited to 4.2-5.5V) supports both 3.3V and 5V designs. Typical applications include industrial control and automation, USB interface adapters (with external MCU-side firmware stack), home appliances, sensor hubs, automotive body controllers (non-AEC-Q100), and consumer electronics requiring moderate computational load with low power draw. Common development tools include MPLAB X IDE, MPLAB XC8 compiler, and PICkit 3/4/5 in-circuit debuggers. When designing with this part, allocate at least 1.0 square inch of PCB copper beneath the QFN thermal pad to meet the 31.5 C/W theta_JA dissipation budget; enable the internal voltage regulator (PIC18F4620 includes an LDO) but always place a 100 nF + 10 uF decoupling pair within 3 mm of each VDD/VSS pair. For bare-metal designs, the device's vectored interrupt controller requires the IVT to be aligned to the 0x000018 boundary.

PIC18F4680-E/ML

PIC18F4680-E/ML - 8-bit 25MHz 64KB Flash MCU w/ECAN | Microchip

The Microchip Technology PIC18F4680-E/ML is an 8-bit PIC18 RISC flash microcontroller integrating 64KB (32K x 16) of program Flash, 3,328 bytes of SRAM, and 1,024 bytes of data EEPROM into a 44-pin QFN (8x8 mm) package with an exposed thermal pad. It supports up to 40 MHz external clock operation (10 MIPS) across a 4.2V to 5.5V supply range, integrates an ECAN module compliant with CAN 2.0B active/passive, and carries nanoWatt power management peripherals for battery-friendly designs. What is a microcontroller? A microcontroller is a compact programmable processor that integrates a CPU, non-volatile program memory (Flash or ROM), volatile data memory (RAM), and configurable peripheral modules onto a single silicon die. Within the broader taxonomy, a microcontroller sits below a microprocessor (which generally requires external memory and peripherals) and above a digital signal controller. The 8-bit PIC18 family specifically targets deterministic real-time embedded control with an enhanced 16-bit instruction word, hardware 8x8 multiplier, and nanoWatt power management. The 8-bit PIC18F4680 is engineered for CAN-bus nodes, automotive body controllers, and industrial sensor networks where deterministic timing and on-chip communication peripherals reduce external component count. Key features of the PIC18F4680-E/ML include an integrated ECAN (Enhanced Controller Area Network) module with hardware acceptance filtering and standard/extended identifier support, a 10-bit ADC with up to 11 input channels, an enhanced USART with LIN master/slave capability, a Master Synchronous Serial Port (MSSP) configurable for SPI or I2C (master/slave), two analog comparators, a programmable 16-level low-voltage detect (LVD), and nanoWatt power-saving modes such as Run, Idle, and Sleep with multiple wake-up sources. The 64KB of self-programmable Flash supports in-application updates via ICSP, enabling firmware revision without removing the MCU from the board. The PIC18F4680-E/ML uses Microchip's enhanced Harvard architecture: separate program and data buses feeding a 16-bit instruction word and an 8-bit data path provide deterministic single-cycle instruction timing, ideal for hard real-time control loops. The integrated ECAN module offloads CAN message filtering and buffering from the CPU; the MSSP allows simultaneous SPI/I2C peripheral connectivity; and nanoWatt technology provides idle and sleep currents in the microamp range for automotive quiescent requirements. The combination of these peripherals positions the PIC18F4680 as a CAN-bus hub MCU bridging LIN sub-buses and SPI sensor front ends. Typical applications include automotive body and chassis ECAN nodes (door modules, lighting, HVAC actuators), industrial CAN-bus sensor and actuator networks, building automation gateways using CAN as the backbone bus, and LIN-bus peripherals in automotive instrument clusters. The combination of ECAN, LIN-capable USART, and MSSP allows a single MCU to bridge multiple automotive and industrial communication buses. When laying out the PCB, connect the exposed thermal pad on the underside of the QFN-44 package directly to the ground plane for both electrical grounding and thermal dissipation. The -E suffix indicates the extended operating temperature range of -40C to +125C, suitable for automotive underhood and industrial environments. Provide a 100 nF decoupling capacitor adjacent to each VDD pin and a bulk capacitor close to the IC, and respect the MCLR reset line trace length guidelines documented in the Microchip PIC18F family reference manual. This page synthesizes distributor pricing, drop-in alternatives from the PIC18 family, and practical design notes not found on a single distributor product page, providing a one-stop engineering reference for selecting the PIC18F4680-E/ML in new designs or as a drop-in upgrade path.
