ATMEL AVR 8-Bit MCU, 64K Flash, 4K RAM, DIP 40-Pin

The ATMEL AVR 8-Bit Microcontroller is a high-performance, low-power CMOS device based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, this microcontroller achieves throughputs approaching 1 MIPS per MHz, allowing system designers to optimise power consumption versus processing speed effectively.

Key Features

• Advanced RISC Architecture with 32 I/O lines
• High Endurance Non-volatile Memory Segments
• JTAG (IEEE Standard 1149.1 Compliant) Interface
• Power-on Reset and Programmable Brown-out Detection
• Internal Calibrated RC Oscillator
• External and Internal Interrupt Sources
• Multiple Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby

Performance Specifications

Designed for efficiency, it operates at a speed grade of 0 to 20MHz within a supply voltage range of 2.7V to 5.5V. Power consumption is meticulously managed, drawing just 0.4mA in active mode, 0.1µA in power-down mode, and 0.6µA in power-save mode with a 32kHz RTC. It features 64KB of program memory and 4KB of RAM. Housed in a 40-pin DIP through-hole package, it measures 43 mm in height, 33 mm in width, and 15 mm in depth, with a weight of 20 grams. It supports I2C, SPI, and UART interfaces, operating reliably between -40°C and 85°C.
