This device is low-power CMOS 8-bit microcontrollers based on the compact AVR enhanced RISCarchitecture. By executing powerful instructions in a single clock cycle, the device achieve throughputsapproaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versusprocessing speed. The AVR core combines a rich instruction set with 16 general purpose working registers and systemregisters. All registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independentregisters to be accessed in one single instruction executed in one clock cycle. The resulting architectureis compact and code efficient while achieving throughputs up to ten times faster than conventional CISCmicrocontrollers. This device provides the following features: 512/1024 byte of In-System Programmable Flash, 32 bytes ofSRAM, four general purpose I/O lines, 16 general purpose working registers, a 16-bit timer/counter withtwo PWM channels, internal and external interrupts, a programmable watchdog timer with internaloscillator, an internal calibrated oscillator, and four software selectable power saving modes. ATtiny5/10are also equipped with a four-channel and 8-bit Analog to Digital Converter (ADC). Idle mode stops the CPU while allowing the SRAM, timer/counter, ADC (ATtiny5/10, only), analogcomparator, and interrupt system to continue functioning. ADC Noise Reduction mode minimizesswitching noise during ADC conversions by stopping the CPU and all I/O modules except the ADC. InPower-down mode registers keep their contents and all chip functions are disabled until the next interrupt or hardware reset. In Standby mode, the oscillator is running while the rest of the device is sleeping,allowing very fast start-up combined with low power consumption. The device is manufactured using Microchip’s high density Non-Volatile Memory (NVM) technology. The onchip,in-system programmable Flash allows program memory to be re-programmed in-system by aconventional, non-volatile memory programmer. The ATtiny4/5/9/10AVR are supported by a suite of program and system development tools, includingmacro assemblers and evaluation kits.
