ATMEGA8535L-8PU [Microchip]

The ATmega8535 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 8K bytes of In-System Programmable Flash with Read-While-Write capabilities, 512 bytes EEPROM, 512 bytes SRAM, 32 general purpose I/O lines, three flexible Timer/Counters with compare modes, an 8-channel 10-bit ADC with optional differential input stage with programmable gain in TQFP package, a programmable Watchdog Timer with Internal Oscillator, a serial programmable USART, a byte-oriented Two-wire Serial Interface, an SPI serial port, and six software selectable power saving modes. The device is manufactured using Atmel's high density nonvolatile memory technology and supports In-System Programming through an SPI serial interface.
