ATMEL 8-Bit AVR ATmega88 Microcontroller, 8KB Flash, 28-Pin DIP

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

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU), enabling two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is significantly more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

Key Features and Memory

Featuring an advanced RISC architecture with 131 powerful instructions, the device supports fully static operation and delivers up to 20MIPS throughput at 20MHz. It includes high endurance non-volatile memory segments, an optional boot code section with independent lock bits, and in-system programming by an on-chip boot program. True Read-While-Write operation and a programming lock for software security are also supported.

Power and Physical Specifications

The microcontroller incorporates power-on reset and programmable brown-out detection, alongside multiple external and internal interrupt sources. It is housed in a 28-pin DIP through-hole package, featuring 23 I/Os and communication interfaces including I2C, SPI, and UART. The unit measures 43 mm in height, 33 mm in width, and 15 mm in depth, with a weight of 6.669 grams.

This versatile component is well-suited for demanding electronics applications requiring reliable and efficient processing capabilities.
