8-bit AVR Microcontroller with 16KB 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 and

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.

The Atmel® ATtiny1634 provides the following features:

● 16KB of in-system programmable Flash

● 1KB 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 USARTs 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 high density nonvolatile memory technology from Atmel. The Flash program memory can

be re-programmed in-system through a serial interface, by a conventional nonvolatile memory programmer or by an on-chip

boot code running on the AVR core.

The Atmel 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.
