The ATtiny15L is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny15L achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny15L provides 1K byte of Flash, 64 bytes EEPROM, six general purpose I/O lines, 32 general purpose working registers, two 8-bit Timer/Counters, one with highspeed PWM output, internal Oscillators, internal and external interrupts, programmable Watchdog Timer, 4-channel 10-bit Analog-to-Digital Converter with one differential voltage input with optional 20x gain, and three software-selectable Power-saving modes. The Idle mode stops the CPU while allowing the ADC, anAlog Comparator, Timer/Counters and interrupt system to continue functioning. The ADC Noise Reduction mode facilitates high-accuracy ADC measurements by stopping the CPU while allowing the ADC to continue functioning. The Power-down mode saves the register contents but freezes the Oscillators, disabling all other chip functions until the next interrupt or Hardware Reset. The wake-up or interrupt on pin change features enable the ATtiny15L to be highly responsive to external events, still featuring the lowest power consumption while in the Power-saving modes.
