Atmel ATtiny84 20MHZ 8K FLASH, 512B RAM

ATtiny84 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny84 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The ATtiny84 provides the following features:

• 14 pin DIL package
• 8K byte of In-System Programmable Flash
• 512 bytes EEPROM
• 512 bytes SRAM
• Maximum Frequency 20MHz
• 12 general purpose I/O lines
• 32 general purpose working registers
• SPI / I2C
• Operating Voltage: 2.7 – 5.5V
• An 8-bit Timer/Counter with two PWM channels
• A 16-bit timer/counter with two PWM channels
• Internal and External Interrupts
• An 8-channel 10-bit ADC
• Programmable gain stage (1x, 20x) for 12 differential ADC channel pairs
• A programmable Watchdog Timer with internal oscillator
• Internal calibrated oscillator
• Four software selectable power saving modes
