Description
General part information
ATtiny4313 Series
The high-performance Microchip picoPower® 8-bit AVR® RISC-based microcontroller combines 4 KB Flash memory, 128B EEPROM, 128B SRAM, 18 general purpose I/O lines, 32 general purpose working registers, a single-wire Interface for on-chip debugging, two flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a universal serial interface (USI) with start condition detector, programmable watchdog timer with internal oscillator, and three software selectable power saving modes. The device operates between 1.8-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
