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
