8-BIT MICROCONTROLLER WITH 2K/4K BYTES
BUILD-IN PROGRAMMABLE FLASH
Description
The IN90S2333 is a low-power CMOS 8-bit
microcontroller based on the AVR RISC architecture. By
executing powerful instructions in a single clock cycle, the
28
IN90S2333 achieves throughputs approaching 1 MIPS
1
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 AT90S2333/4433 provides the following features: 2K/4K bytes of In-System
Programmable Flash, 128/256 bytes EEPROM, 128 bytes 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
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 nonvolatile memory
technology. The on-chip Flash program memory can be reprogrammed in-system through
an SPI serial interface or by a conventional nonvolatile memory programmer. By
combining a RISC 8-bit CPU with In-System Programmable Flash on a monolithic chip, the
Atmel AT90S2333/4433 is a powerful microcontroller that provides a highly flexible and
cost effective solution to many embedded control applications. The AT90S2333/4433 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.
