The ATTIny15L is a low-power CMOS 8-bit microcontroller based on the AVR RISCarchitecture. By execuTIng powerful instrucTIons in a single clock cycle, the ATTIny15Lachieves throughputs approaching 1 MIPS per MHz allowing the system designer tooptimize 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), allowingtwo independent registers to be accessed in one single instruction executed in one clockcycle. The resulting architecture is more code efficient while achieving throughputs up toten times faster than conventional CISC microcontrollers.The ATtiny15L provides 1K byte of Flash, 64 bytes EEPROM, six general purpose I/Olines, 32 general purpose working registers, two 8-bit Timer/Counters, one with highspeedPWM output, internal oscillators, internal and external interrupts, programmableWatchdog Timer, 4-channel 10-bit Analog-to-Digital Converter with one differential voltageinput 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 Reductionmode facilitates high-accuracy ADC measurements by stopping the CPU while allowingthe ADC to continue functioning. The Power-down mode saves the register contents butfreezes the oscillators, disabling all other chip functions until the next interrupt or hardwarereset. The wake-up or interrupt on pin change features enable the ATtiny15L to behighly responsive to external events, still featuring the lowest power consumption whilein the Power-saving modes.The device is manufactured using Atmel’s high-density, nonvolatile memory technology.By combining a RISC 8-bit CPU with Flash on a monolithic chip, the ATtiny15L is a powerfulmicrocontroller that provides a highly flexible and cost-efficient solution to manyembedded control applications. The peripheral features make the ATtiny15L particularlysuited for battery chargers, lighting ballasts and all kinds of intelligent sensorapplications.The ATtiny15L AVR is supported with a full suite of program and system developmenttools including macro assemblers, program debugger/simulators, In-circuit emulatorsand evaluation kits
