Datasheet Summary
Powered by GS/AI

The Microcontroller MCU, 8 Bit, Atmega, 20MHz, TQFP-44 is designed for high-performance, low-power applications. It features an advanced RISC architecture with 131 powerful instructions, allowing for most operations to be executed in a single clock cycle. The microcontroller operates at a maximum throughput of 20 MIPS at 20 MHz and includes a 2-cycle multiplier. It offers a range of memory options, including 16K, 32K, or 64K bytes of in-system self-programmable Flash program memory, 512B to 2K bytes of EEPROM, and 1K to 4K bytes of internal SRAM. The Flash memory supports 10,000 write/erase cycles, while the EEPROM can endure 100,000 cycles, with data retention of 20 years at 85¬8C and 100 years at 25¬8C. The microcontroller is equipped with various peripherals, including two 8-bit timer/counters, one 16-bit timer/counter, a real-time counter, six PWM channels, and an 8-channel, 10-bit ADC. It also supports multiple communication interfaces such as USART and SPI, along with a programmable watchdog timer and an on-chip analog comparator. With 32 programmable I/O lines and available in multiple package styles, including TQFP-44, this microcontroller operates within a voltage range of 1.8V to 5.5V. It is suitable for a variety of applications requiring efficient processing and extensive peripheral support.
