Description
1042H–AVR–04/03
The AT90S4433 is a low-power CMOS 8-bit microcontroller based on the AVR RISC
architecture. By executing powerful instructions in a single clock cycle, the AT90S4433
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 AT90S4433 provides the following features: 4K bytes of In-System Programmable
Flash, 256 bytes of EEPROM, 128 bytes of SRAM, 20 general purpose I/O lines, 32
general purpose working registers, two flexible Timer/Counters with compare modes,
internal and external interrupts, a programmable serial UART, 6-channel, 10-bit ADC,
programmable Watchdog Timer with internal Oscillator, an SPI serial port and two soft-
ware-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 Flash Program memory can be re-programmed In-System through an SPI
serial interface or by a conventional non-volatile memory programmer. By combining a
RISC 8-bit CPU with In-System Programmable Flash on a monolithic chip, the Atmel
AT90S4433 is a powerful microcontroller that provides a highly flexible and cost-effec-
tive solution to many embedded control applications.
The AT90S4433 AVR 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.
