Category: Microcontroller IC
ATMEL ATmega8A U PDIP-28 Microcontroller from Atmega8A family is a high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 8KB ISP flash memory, 1KB SRAM, 512B EEPROM, a 7-channel/10-bit A/D converter (TQFP and QFN/MLF), and debugWIRE for on-chip debugging. The device supports a throughput of 16 MIPS at 16 MHz and operates between 4.5-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
Product Images are shown for illustrative purposes only and may differ from the actual product.
The available IC is ATmega8A-U.
