ATmega164/324/644

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 conventional CISC microcontrollers.

The ATmega164/324/644 provides the following features: 16/32/64K bytes of In-System

Programmable Flash with Read-While-Write capabilities, 512B/1K/2K bytes EEPROM,

1/2/4K bytes SRAM, 32 general purpose I/O lines, 32 general purpose working regis-

ters, Real Time Counter (RTC), three flexible Timer/Counters with compare modes and

PWM, 2 USARTs, a byte oriented 2-wire Serial Interface, a 8-channel, 10-bit ADC with

optional differential input stage with programmable gain, programmable Watchdog

Timer with Internal Oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test

interface, also used for accessing the On-chip Debug system and programming and six

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 dur-

ing ADC conversions. In Standby mode, the Crystal/Resonator 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 Oscillator and the Asyn-

chronous Timer continue to run.

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

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

by an 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. Soft-

ware 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-Program mable Flash on a monolithic ch ip, the Atmel

ATmega164/324/644 is a powerful microcontroller that provides a highly flexible and

cost effective solution to many embedded control applications.

The ATmega164/324/644 AVR is supported with a full suite of program and system

development tools including: C compilers, macro assemblers, program debugger/simu-

lators, in-circuit emulators, and evaluation kits.
