ATtiny828 provides the following features:
z 8K bytes of in-system programmable Flash
z 512 bytes of SRAM data memory
z 256 bytes of EEPROM data memory
z 28 general purpose I/O lines
z 32 general purpose working registers
z An 8-bit timer/counter with two PWM channels
z A16-bit timer/counter with two PWM channels
z Internal and external interrupts
z A 10-bit ADC with 4 internal and 28 external chanels
z An ultra-low power, programmable watchdog timer with internal oscillator
z A programmable USART with start frame detection
z A slave, I2C compliant Two-Wire Interface (TWI)
z A master/slave Serial Peripheral Interface (SPI)
z A calibrated 8MHz oscillator
z A calibrated 32kHz, ultra low power oscillator
z Three software selectable power saving modes.
The device includes the following modes for saving power:
z Idle mode: stops the CPU while allowing the timer/counter, ADC, analog comparator, SPI, TWI, and interrupt
system to continue functioning
z ADC Noise Reduction mode: minimizes switching noise during ADC conversions by stopping the CPU and all I/O
modules except the ADC
z Power-down mode: registers keep their contents and all chip functions are disabled until the next interrupt or
hardware reset
The device is manufactured using Atmel’s high density non-volatile memory technology. The Flash program memory 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 boot program can use any interface to download the application program
to the Flash memory. Software in the boot section of the Flash executes while the application section of the Flash is
updated, providing true read-while-write operation.
The ATtiny828 AVR is supported by a full suite of program and system development tools including: C compilers, macro
assemblers, program debugger/simulators and evaluation kits.
