Spectrum Signal (DSSS) processing with spreading and despreading. The device is

fully compatible with IEEE802.15.4-2011/2006/2003 and ZigBee standards.

The ATmega2564/1284/644RFR2 provides the following features: 256K/128K/64K

Bytes of In-System Programmable (ISP) Flash with read-while-write capabilities,

8K/4K/2K Bytes EEPROM, 32K/16K/8K Bytes SRAM, up to 35 general purpose I/O

lines, 32 general purpose working registers, Real Time Counter (RTC), 6 flexible

Timer/Counters with compare modes and PWM, a 32 bit Timer/Counter, 2 USART, a

byte oriented 2-wire Serial Interface, a 8 channel, 10 bit analog to digital converter

(ADC) with an optional differential input stage with programmable gain, programmable

Watchdog Timer with Internal Oscillator, a SPI serial port, IEEE std. 1149.1 compliant

JTAG test interface, also used for accessing the On-chip Debug system and

programming and 6 software selectable power saving modes.

The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and

interrupt system to continue functioning. The Power-down mode saves the register

contents but freezes the Oscillator, disabling all other chip functions until the next

interrupt or hardware reset. In Power-save mode, the asynchronous timer continues to

run, allowing the user to maintain a timer base while the rest of the device is sleeping.

The ADC Noise Reduction mode stops the CPU and all I/O modules except

asynchronous timer and ADC, to minimize switching noise during ADC conversions. In

Standby mode, the RC oscillator is running while the rest of the device is sleeping. This

allows very fast start-up combined with low power consumption. In Extended Standby

mode, both the main RC oscillator and the asynchronous timer continue to run.

Typical supply current of the microcontroller with CPU clock set to 16MHz and the radio

transceiver for the most important states is shown in the

Figure 3-2 below.

Radio transceiver and microcontroller (16MHz) supply current

The transmit output power is set to maximum. If the radio transceiver is in SLEEP mode

the current is dissipated by the AVR microcontroller only.

In Deep Sleep mode all major digital blocks with no data retention requirements are

disconnected from main supply providing a very small leakage current. Watchdog timer,

MAC symbol counter and 32.768kHz oscillator can be configured to continue to run.

42073B-MCU Wireless-09/14

ATmega2564/1284/644RFR2

The device is manufactured using Atmel’s high-density nonvolatile memory technology.

The On-chip ISP Flash allows the program memory to be reprogrammed in-system

trough an SPI serial interface, by a conventional nonvolatile memory programmer, or by

on on-chip boot program running on the AVR core. The boot program can use any

interface to download the application program in the application Flash memory.

Software in the boot Flash section will continue to run while the application Flash

section is updated, providing true Read-While-Write operation. By combining an 8 bit

RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel

ATmega2564/1284/644RFR2 is a powerful microcontroller that provides a highly

flexible and cost effective solution to many embedded control applications.

The ATmega2564/1284/644RFR2 AVR is supported with a full suite of program and

system development tools including: C compiler, macro assemblers, program

debugger/simulators, in-circuit emulators, and evaluation kits.

3.2.7 Port B (PB7...PB0)

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port B output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port B pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port B also provides functions

3.2.8 Port D (PD7...PD0)

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port D output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port D pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset

condition becomes active, even if the clock is not running.
