ATTINY1634-MF

8-bit Atmel tinyAVR Microcontroller with 16K Bytes In-System Programmable Flash

Atmel Corporation 

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are

directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in a single

instruction, executed in one clock cycle. The resulting architecture is compact and code efficient while achieving

throughputs up to ten times faster than conventional CISC microcontrollers.

ATtiny1634 provides the following features:

• 16K bytes of in-system programmable Flash

• 1K bytes of SRAM data memory

• 256 bytes of EEPROM data memory

• 18 general purpose I/O lines

• 32 general purpose working registers

• An 8-bit timer/counter with two PWM channels

• A16-bit timer/counter with two PWM channels

• Internal and external interrupts

• A 10-bit ADC with 5 internal and 12 external channels

• An ultra-low power, programmable watchdog timer with internal oscillator

• Two programmable USART’s with start frame detection

• A slave Two-Wire Interface (TWI)

• A Universal Serial Interface (USI) with start condition detector

• A calibrated 8MHz oscillator

• A calibrated 32kHz, ultra low power oscillator

• Four software selectable power saving modes.

The device includes the following modes for saving power:

• Idle mode: stops the CPU while allowing the timer/counter, ADC, analog comparator, SPI, TWI, and interrupt

system to continue functioning

• ADC Noise Reduction mode: minimizes switching noise during ADC conversions by stopping the CPU and all

I/O modules except the ADC

• Power-down mode: registers keep their contents and all chip functions are disabled until the next interrupt or

hardware reset

• 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 Atmel’s high density non-volatile memory technology. The Flash program mem-

ory can be re-programmed in-system through a serial interface, by a conventional non-volatile memory

programmer or by an on-chip boot code, running on the AVR core.

The ATtiny1634 AVR is supported by a full suite of program and system development tools including: C compilers,

macro assemblers, program debugger/simulators and evaluation kits.
