2490R–AVR–02/2013

ATmega64(L)

The ATmega64 provides the following features: 64 Kbytes of In-System Programmable Flash

with Read-While-Write capabilities, 2 Kbytes EEPROM, 4 Kbytes SRAM, 53 general purpose I/O

lines, 32 general purpose working registers, Real Time Counter (RTC), four flexible Timer/Coun-

ters with compare modes and PWM, two USARTs, a byte oriented Two-wire Serial Interface, an

8-channel, 10-bit ADC with optional differential input stage with programmable gain, program-

mable 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 contin-

ues 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 crys-

tal/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 asynchronous timer continue to run.

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

On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI

serial interface, by a conventional non-volatile memory programmer, or by an On-chip Boot pro-

gram 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 ATmega64 is a powerful microcontroller that provides a highly-flexible

and cost-effective solution to many embedded control applications.

The ATmega64 AVR is supported with a full suite of program and system development tools

including: C compilers, macro assemblers, program debugger/simulators, In-Circuit Emulators,

and evaluation kits.

ATmega103 and

ATmega64

Compatibility

The ATmega64 is a highly complex microcontroller where the number of I/O locations super-

sedes the 64 I/O location reserved in the AVR instruction set. To ensure backward compatibility

with the ATmega103, all I/O locations present in ATmega103 have the same location in

ATmega64. Most additional I/O locations are added in an Extended I/O space starting from 0x60

to 0xFF (that is, in the ATmega103 internal RAM space). These location can be reached by

using LD/LDS/LDD and ST/STS/STD instructions only, not by using IN and OUT instructions.

The relocation of the internal RAM space may still be a problem for ATmega103 users. Also, the

increased number of Interrupt Vectors might be a problem if the code uses absolute addresses.

To solve these problems, an ATmega103 compatibility mode can be selected by programming

the fuse M103C. In this mode, none of the functions in the Extended I/O space are in use, so the

internal RAM is located as in ATmega103. Also, the extended Interrupt Vectors are removed.

The ATmega64 is 100% pin compatible with ATmega103, and can replace the ATmega103 on

current printed circuit boards. The application notes “Replacing ATmega103 by ATmega128”

and “Migration between ATmega64 and ATmega128” describes what the user should be aware

of replacing the ATmega103 by an ATmega128 or ATmega64.

ATmega103

Compatibility Mode

By programming the M103C Fuse, the ATmega64 will be compatible with the ATmega103

regards to RAM, I/O pins and Interrupt Vectors as described above. However, some new fea-

tures in ATmega64 are not available in this compatibility mode, these features are listed below:

•

One USART instead of two, asynchronous mode only. Only the eight least significant bits of

the Baud Rate Register is available.

One 16 bits Timer/Counter with two compare registers instead of two 16 bits Timer/Counters

with three compare registers.

Two-wire serial interface is not supported.

Port G serves alternate functions only (not a general I/O port).

Port F serves as digital input only in addition to analog input to the ADC.

Boot Loader capabilities is not supported.

It is not possible to adjust the frequency of the internal calibrated RC Oscillator.

The External Memory Interface can not release any Address pins for general I/O, neither

configure different wait states to different External Memory Address sections.

Only EXTRF and PORF exist in the MCUCSR Register.

No timed sequence is required for Watchdog Timeout change.

Only low-level external interrupts can be used on four of the eight External Interrupt sources.

Port C is output only.

USART has no FIFO buffer, so Data OverRun comes earlier.

The user must have set unused I/O bits to 0 in ATmega103 programs.

Pin Descriptions

VCC

GND

Port A (PA7..PA0)

Digital supply voltage.

Ground.

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

Port A output buffers have symmetrical drive characteristics with both high sink and source

capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up

resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,

even if the clock is not running.

Port A also serves the functions of various special features of the ATmega64 as listed on

page

73.

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 serves the functions of various special features of the ATmega64 as listed on

page
