ATMEGA8515-16PU

Description

ATmega8515 AVR MCU, 8 KB flash, 16 MHz, DIP-40 — external-bus capable.

ATMEGA8515-16PU AVR AVR® ATmega Microcontroller IC 8-Bit 16MHz 8KB (4K x 16) FLASH 40-PDIP 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 system designer to optimize power consumption versus processing speed. 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 interrupts, 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 butfreezes the Osci
