The ATtiny167 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC
architecture. By executing powerful instructions in a single clock cycle, the ATtiny167 achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-
sumption 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 con-
ventional CISC microcontrollers.
The ATtiny167 provides the following features: 16K byte of In-System Programmable Flash, 512
bytes EEPROM, 512 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working reg-
isters, one 8-bit Timer/Counter with compare modes, one 8-bit high speed Timer/Counter,
Universal Serial Interface, a LIN controller, 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 contents, 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 min-
imize 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 Boot program can use any interface to download the application
program in the Flash memory. By combining an 8-bit RISC CPU with In-System Self-Program-
mable Flash on a monolithic chip, the Atmel ATtiny167 is a powerful microcontroller that
provides a highly flexible and cost effective solution to many embedded control applications.
The ATtiny167 AVR is supported with a full suite of program and system development tools
including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators,
and Evaluation kits.
