AT90S2313

0839I–AVR–06/02

Description

The AT90S2313 is a low-power CMOS 8-bit microcontroller based on the AVR RISC

architecture. By executing powerful instructions in a single clock cycle, the AT90S2313

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 AT90S2313 provides the following features: 2K bytes of In-System Programmable

Flash, 128 bytes EEPROM, 128 bytes SRAM, 15 general purpose I/O lines, 32 general

purpose working registers, flexible Timer/Counters with compare modes, internal and

external interrupts, a programmable serial UART, programmable Watchdog Timer with

internal Oscillator, an SPI serial port for Flash memory downloading and two software
