ATMEGA8515 Microcontroller

The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 2KB ISP flash memory, 128B ISP EEPROM, 128B internal SRAM, universal serial interface (USI), full duplex UART, and debugWIRE for on-chip debugging. The device supports a throughput of 20 MIPS at 20 MHz and operates between 2.7-5.5 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.

ATtiny85 is a small 8-pin microcontroller from Atmel and is based on Atmel's 8-bit RISC architecture. ATtiny85 is a high-performance, low-power microcontroller which combines 8KB ISP flash memory, 512B EEPROM, 512-Byte SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external Interrupts, 4-channel 10-bit Analog to Digital converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes, and debug WIRE for on-chip debugging. The device achieves a throughput of 20 MIPS at 20 MHz and operates between 2.7-5.5 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.

The ATmega48A-PU is  a  low  power,  CMOS  8-bit  microcontrollers  based  on  the AVR® enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU through put approaching one million instructions per second (MIPS) per mega hertz, allowing the system designer to optimize power consumption versus processing speed.
