ATmega8 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerf
ul instructions in a single clock cycle, the ATmega8 achieves
throughputs approaching 1MIPS per MHz, allowing the system designer to optimize power con-

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 inde-
struction executed in one clock cycle. The resulting architecture is more code efficient wh ile achieving throughputs up to ten times faster than conventional CISC microcontrollers.
The ATmega8 provides the following features: 8 Kbytes of In-System Programmable Flash with
Read-While-Write capabilities, 512 bytes of EEPROM, 1 Kbyte of SRAM, 23 general purpose
I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a seri al programmable USART, a byte oriented Two-
wire Serial Interface, a 6-channel ADC (eight channels in TQFP and QFN/MLF packages) with
10-bit accuracy, a programmable Watchdog Timer with Internal Os cillator, an SPI serial port,
and five software selectable power saving modes. The Idle mode stops the CPU while allowing
the SRAM, Timer/Counters, SPI port, and interr upt system to continue functioning. The Power- down mode saves the register contents but freezes the Oscillator, disabling all other chip func-
tions 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 sleep-
ing. 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 crystal/resonator Oscillator is running while the re st of the device is sleeping. This allows very
fast start-up combined with low-power consumption. The device is manufactured using Atmel’s high density non-volatile memory technology. The
Flash Program memory can be reprogrammed In-System through an SPI serial interface, by a
conventional non-volatile 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 . Software in the Boot Flash Sect ion will continue to run while the
an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel
ATmega8 is a powerful microcontroller that provides a highly-flexible and cost-effective solution
to many embedded control applications.
The ATmega8 is supported with a full suite of program and system development tools, including
C compilers, macro assemblers, program simulators, and evaluation kits. Disclaimer
Typical values contained in this datasheet ar e based on simulations and characterization of other AVR microcontrollers manufactured on t he same process technology. Minimum and Maxi- mum values will be available afte

Port B (PB7..PB0) XTAL1/XTAL2/TOSC1/ TOSC2
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 pi
ns 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.
Depending on the clock selection fuse settings, PB6 can be used as input to the inverting Oscil-
lator amplifier and input to the internal clock operating circuit.
Depending on the clock selection fuse settings, PB7 can be used as output from the inverting
Oscillator amplifier. If the Internal Calibrate d RC Oscillator is used
as chip clock source, PB7..6 is used as TOSC2..1 input for the Asynch
e AS2 bit in ASSR is set.
The various special features of Port B are elaborated in “Alternate Functions of Port B” on page
58 and
“System Clock and Clock Options” on page 25 .
Port C (PC5..PC0)
Port C is an 7-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port C output buffers have symmetrical drive c haracteristics with bot
h high sink and source
capability. As inputs, Port C pi ns that are externally pulled lo w will source current if the pull-up
resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,
even if the clock is not running. PC6/RESET
If the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical char-
acteristics of PC6 differ from those of the other pins of Port C.
If the RSTDISBL Fuse is unprogrammed, PC6 is used as a Reset input. A low level on this pin
for longer than the minimum pulse a Reset, even if the clock is not running. The minimum pulse length is given in Table 15 on page 38
. Shorter pulses are not guaranteed to generate a Reset.
The various special features of Port C are elaborated on page 61
.
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 c haracteristics with bot
h high sink and source
capability. As inputs, Port D pi ns that are externally pulled lo w 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.
