The ATtiny13 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISCarchitecture. By executing powerful instructions in a single clock cycle, the ATtiny13 achievesthroughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumptionversus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All 32registers 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 resultingarchitecture is more code efficient while achieving throughputs up to ten times faster than conventionalCISC microcontrollers. The ATtiny13 provides the following features: 1K byte of In-System Programmable Flash, 64bytes EEPROM, 64 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working registers,one 8-bit Timer/Counter with compare modes, Internal and External Interrupts, a 4-channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, and three softwareselectable power saving modes. The Idle mode stops the CPU while allowing the SRAM,Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue functioning. ThePower-down mode saves the register contents, disabling all chip functions until the next Interruptor Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O modulesexcept ADC, to minimize switching noise during ADC conversions. The device is manufactured using Microchip’s high density non-volatile memory technology. TheOn-chip ISP Flash allows the Program memory to be re-programmed In-System through an SPIserial interface, by a conventional non-volatile memory programmer or by an On-chip boot coderunning on the AVR core. The ATtiny13 AVR is supported with a full suite of program and system development toolsincluding: C Compilers, Macro Assemblers, Program Debugger/Simulators, and Evaluation kits.
