ATtiny1634 [DATASHEET]
Atmel-8303HS-AVR-ATtiny1634-Summary_02/2014
• PC5:PC1: Symmetrical, with standard sink and source capability
• PC0: Asymmetrical, with high sink and standard source capability
As inputs, port pins that are externally pulled low will source current provided that pull-up resistors are activated.
Port pins are tri-stated when a reset condition becomes active, even if the clock is not running.
This port has alternate pin functions to serve special features of the device. See “Alternate Functions of Port C” on
page 67.
2. Overview
ATtiny1634 is a low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By exe-
cuting powerful instructions in a single clock cycle, the ATtiny1634 achieves throughputs approaching 1 MIPS per
MHz allowing the system designer to optimize power consumption versus processing speed.
