Product Details

An 8-bit low-power CMOS microcontroller built on the AVR improved RISC architecture is called the ATmega8A. The ATmega8A achieves throughputs near to 1 MIPS per MHz by processing strong instructions in a single clock cycle. This gives system designers the ability to balance the device's power use and processing performance.

High density nonvolatile memory technology from Microchip is used in the creation of the product. Through an SPI serial interface, a typical nonvolatile memory programmer, or an on-chip Boot software running on the AVR core, the on-chip ISP Flash enables In-System reprogramming of the programme memory. The application software in the Application Flash memory can be downloaded by the Boot programme via any interface. The Application Flash part will be updated while the software in the Boot Flash area is still operating, enabling real Read-While-Write functioning. The ATmega8A is a potent microcontroller that offers a highly versatile and economical solution to many embedded control applications by combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic device.
