ATMEGA8535 Programming Manual

●The ATMEGA8535-16AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 8kB of programmable flash memory, 544B SRAM, 512byte EEPROM and an 8-channel 10-bit A/D converter. The device supports throughput of 16MIPS at 16MHz and operates between 4.5 to 5.5V. By executing instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using Atmel"s high density nonvolatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an on-chip boot program running on the AVR core. The boot program can use any interface to download the application program in the application flash memory.
