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 ATtiny13 provides the following features: 1K byte of In-System Programmable
Flash, 64 bytes EEPROM, 64 bytes SRAM, 6 general purpose I/O lines, 32 general pur-
pose 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 software selectable power saving modes. The Idle mode
stops the CPU while allowing the SRAM, Timer/Counter, ADC, Analog Comparator, and
Interrupt system to continue functioning. The Power-down mode saves the register con-
tents, disabling all chip functions until the next Interrupt or Hardware Reset. The ADC
Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize
switching noise during ADC conversions.
The device is manufactured using Atmel’s high density non-volatile memory technology.
The On-chip ISP Flash allows the Program memory to be re-programmed In-System
through an SPI serial interface, by a conventional non-volatile memory programmer or
by an On-chip boot code running on the AVR core.
The ATtiny13 AVR is supported with a full suite of program and system development
tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Cir-
cuit Emulators, and Evaluation kits.
