3 ATMEGA8515(l) 2512fs?avr?12/03 overview the ATMEGA8515 is a low-power cmos 8-bit microcontroller based on the avr enhanced risc architecture. by executing powerful instructions in a single clock cycle, the ATMEGA8515 achieves throughputs approaching 1 mips per mhz allowing the sys- tem designer to optimize power consumption versus processing speed. block diagram figure 2. block diagram internal oscillator watchdog timer mcu ctrl. & timing oscillator timers/ counters interrupt unit stack pointer eeprom sram status register usart program counter program flash instruction register instruction decoder programming logic spi comp. interface porta drivers/buffers porta digital interface general purpose registers x y z alu + - portc drivers/buffers portc digital interface portb digital interface portb drivers/buffers portd digital interface portd drivers/buffers xtal1 xtal2 reset control lines vcc gnd pa0 - pa7 pc0 - pc7 pd0 - pd7 pb0 - pb7 avr cpu internal calibrated oscillator porte drivers/ buffers porte digital interface pe0 - pe2
4 ATMEGA8515(l) 2512fs?avr?12/03 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 ATMEGA8515 provides the following features: 8k bytes of in-system programmable flash with read-while-write capabilities, 512 bytes eeprom, 512 bytes sram, an external memory interface, 35 general purpose i/o lines, 32 general purpose working registers, two flexible timer/counters with compare modes, internal and external inter- rupts, a serial programmable usart, a programmable watchdog timer with internal oscillator, a spi serial port, and three 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 hard- ware reset. 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. 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 t he 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-programmable flash on a monolithic chip, the atmel ATMEGA8515 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. the ATMEGA8515 is supported with a full suite of program and system development tools including: c compilers, macro assemblers, program debugger/simulators, in-cir- cuit emulators, and evaluation kits. disclaimer typical values contained in this datasheet are based on simulations and characteriza- tion of other avr microcontrollers manufactured on the same process technology. min and max values will be available after the device is characterized. at90s4414/8515 and ATMEGA8515 compatibility the ATMEGA8515 provides all the features of the at90s4414/8515. in addition, several new features are added. the ATMEGA8515 is backward compatible with at90s4414/8515 in most cases. however, some incompatibilities between the two microcontrollers exist. to solve this problem, an at90s4414/8515 compatibility mode can be selected by programming the s8515c fuse. ATMEGA8515 is 100% pin compati- ble with at90s4414/8515, and can replace the at90s4414/8515 on current printed circuit boards. however, the location of fuse bits and the electrical characteristics dif- fers between the two devices. at90s4414/8515 compatibility mode programming the s8515c fuse will change the following functionality: the timed sequence for changing the watchdog time-out period is disabled. see ?timed sequences for changing the configuration of the watchdog timer? on page 52 for details. the double buffering of the usart receive registers is disabled. see ?avr usart vs. avr uart ? compatibility? on page 135 for details. porte(2:1) will be set as output, and porte0 will be set as input.
