ATMEGA32U4-AU MICROCHIP Microcontroller
The ATMEGA32U4-AU is an 8‑bit AVR RISC MCU from Microchip in a 44‑pin TQFP package. Verify supply voltage 2.7 V to 5.5 V and ensure –40 °C to +85 °C operation [6†L9-L22]. Confirm 32 KB Flash, 2.5 KB SRAM, 1 KB EEPROM meet memory needs [5†L28-L30] [6†L6-L10]. The 16 MHz core (16 MIPS) features USB 2.0 full‑speed (12 Mbps) and low‑speed, 12‑channel 10‑bit ADC, 26 I/Os, 8 PWM, SPI, I2C, UART/USART, plus JTAG debug [5†L14-L17] [6†L6-L14] [10†L8-L10]. Ideal for custom USB HID keyboards/mice, MIDI controllers, consumer electronics, industrial control, robotics, Arduino‑based designs and battery‑powered IoT nodes requiring integrated USB [1†L25-L26] [2†L6-L14] [9†L44-L45].
