The Microchip ATMEGA8535-16AU is an 8-bit AVR microcontroller that provides 8 KB of flash, 512 bytes of SRAM and 512 bytes of EEPROM in a 44-lead TQFP package, operating at up to 16 MHz from a 4.5 V to 5.5 V supply. It integrates a 10-bit ADC, USART, SPI and TWI, together with PWM and multiple timer/counters. Its compact 44-pin form factor makes it a cost-effective choice for smaller embedded control and sensing tasks.
