ATMEGA1608-MU

ATmega1608-MU is an 8‑bit AVR microcontroller from Microchip/Atmel in the megaAVR family. It uses a RISC AVR core with on‑chip flash, SRAM, and EEPROM, plus I/O pins and on‑chip peripherals such as timers, PWM, ADC, analog comparator, and serial interfaces (USART, SPI, I2C/TWI). It supports low‑power sleep modes, watchdog timer, and brown‑out detection for reliable operation. The -MU suffix denotes a 32‑pin QFN/MLF packaging option. Operating voltage and maximum clock are device‑dependent; consult the datasheet for exact figures. Typical uses include small embedded controllers in sensors, appliances, and hobby projects. Development is supported by Microchip Studio and GCC‑based toolchains, with programming via the interface documented in the datasheet.

Not an exact drop-in. Closest equivalents in the same MU package (megaAVR 0-series) are: ATmega1604-MU, ATmega1606-MU, ATmega1614-MU, ATmega1616-MU. For different flash sizes or packages, a redesign may be required; check Microchip’s cross-reference table for exact substitutes.
