IN90S2313DW,
8-BIT MICROCONTROLLER WITH 2K BYTES BUILD-IN
PROGRAMMABLE FLASH
Description
The IN90S2313 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 IN90S2313 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 IN90S2313 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
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 hardware reset. The device is manufactured using
Atmel’s high density non-volatile memory technology. The on-chip In-System
Programmable Flash allows the program memory to be reprogrammed in-system
through an SPI serial interface or by a conventional nonvolatile memory programmer. By
combining an enhanced RISC 8-bit CPU with In-System Programmable Flash on a
monolithic chip, the Atmel IN90S2313 is a powerful microcontroller that provides a highly
flexible and cost effective solution to many embedded control applications.
The IN90S2313 AVR is supported with a full suite of program and system development
tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit
emulators, and evaluation kits.
