The ATMEGA32U4RC-MU is an 8-bit AVR microcontroller from Microchip, featuring a 32KB flash and 2.5KB SRAM. It operates at 16MHz with a 2.7V-5.5V supply, and includes a USB 2.0 controller, PWM, and multiple serial interfaces. Housed in a compact 44-VFQFN package, it is designed for embedded control and USB-enabled applications.
- Integrated USB 2.0 full-speed controller – eliminates external USB bridge ICs, reducing BOM cost.
- Wide voltage range (2.7V-5.5V) – supports both 3.3V and 5V systems without level shifters.
- Low-power sleep modes – extends battery life in portable devices.
- AVR core with 16MHz – provides predictable single-cycle execution for time-critical tasks.
USB HID Devices
Ideal for keyboards, mice, and game controllers due to its native USB 2.0 full-speed interface and 32KB flash for firmware.
Portable Instrumentation
Low power consumption (down to 1.8V operation) and 2.5KB SRAM support battery-powered data loggers and handheld meters.
Custom Mechanical Keyboards
Supports complex matrix scanning and RGB LED control via PWM channels, with 16MHz throughput for low-latency input.
Industrial Control Panels
Robust I/O with brown-out detection and watchdog timer ensures reliable operation in noisy environments.
Consumer Electronics
Compact 44-VFQFN package fits space-constrained designs like smart home sensors and remote controls.
Prototyping & Education
Arduino-compatible bootloader support accelerates development for STEM projects and rapid prototyping.
