Description
General part information
ATtiny84A Series
The high-performance, Microchip's picoPower® 8-bit AVR® RISC-based microcontroller combines 8 KB ISP Flash memory, 512B EEPROM, 512B SRAM, 12 general purpose I/O lines, 32 general purpose working registers, two timer/counters (8-bit/16-bit) with two PWM channels each, internal and external interrupts, 8-channel 10-bit A/D converter, programmable gain stage (1x, 20x) for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internal calibrated oscillator, and four 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 processor speed.
