Atmel ATtiny2313-20PU AVR Microcontroller, 20 DIP, 20 MHz

Description

Atmel ATtiny2313-20PU AVR Microcontroller, 20 DIP, 20 MHz
ATtiny2313-20P
Low-power CMOS 8-bit AVR microcontroller in 20-pin DIP package, Lead-free, RoHS compliant
By executing powerful instructions in a single clock cycle, the ATtiny2313 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
Note: The ATtiny2313-20PU is identical in function to the ATtiny2313-20PI. The only difference is that the -20PU comes in a lead-free RoHS-compliant package.
Features include 2 Kbytes of In-System Programmable Flash, 128 Bytes EEPROM, 128 Bytes 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, a serial programmable USART, Universal Serial Interface with Start Condition Detector, a programmable Watchdog Timer with internal Oscillator, and three software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset. In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low-power consumption.
