ATMEGA32-16MU

The ATMEGA32-16MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It is based on the AVR RISC architecture and operates at a maximum clock frequency of 16 MHz, delivering up to 16 MIPS throughput. The device integrates 32 KB of in-system self-programmable Flash memory, 2 KB of SRAM, and 1 KB of EEPROM, with write/erase endurance of 10,000 cycles for Flash and 100,000 cycles for EEPROM. Data retention is rated at 20 years at 85°C and 100 years at 25°C.

Peripheral features include two 8-bit timer/counters, one 16-bit timer/counter, four PWM channels, an 8-channel 10-bit ADC, and a real-time counter with separate oscillator. Communication interfaces include I²C, SPI, and USART. The device also includes a JTAG interface for boundary-scan and on-chip debug. On-chip analog comparator, brown-out detection, power-on reset, and programmable watchdog timer are integrated.

The ATMEGA32-16MU is supplied in a 44-pad QFN (44-VQFN) package with exposed pad for thermal management. It operates over a voltage range of 4.5V to 5.5V and a temperature range of -40°C to +85°C. The device is surface mount and RoHS3 compliant. This microcontroller is suitable for a wide range of embedded control applications, including industrial automation, consumer electronics, and automotive systems.
