Description

The AT90S2333/4433 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing pow-

erful instructions in a single clock cycle, the AT90S2333/4433 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 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 function-

ing. 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 mem-

ory 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.

Pin Descriptions

VCC

Supply voltage

GND

Ground

Port B (PB5..PB0)

Port B is a 6-bit bi-directional I/O port with internal pullup resistors. The Port B output buffers can sink 20 mA. As inputs,

Port B pins that are externally pulled low will source current if the pull-up resistors are activated.

Port B also serves the functions of various special features of the AT90S2333/4433.

The port B pins are tristated when a reset condition becomes active, even if the clock is not running.

Port C (PC5..PC0)

Port C is a 6-bit bi-directional I/O port with internal pullup resistors. The Port C output buffers can sink 20 mA. As inputs,

Port C pins that are externally pulled low will source current if the pull-up resistors are activated. Port C also serves as the

analog inputs to the A/D Converter.

The port C pins are tristated when a reset condition becomes active, even if the clock is not running.

Port D (PD7..PD0)

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors. The Port D output buffers can sink 20 mA. As inputs,

Port D pins that are externally pulled low will source current if the pull-up resistors are activated.

Port D also serves the functions of various special features of the AT90S2333/4433.

The port D pins are tristated when a reset condition becomes active, even if the clock is not running.

RESET

Reset input. An external reset is generated by a low level on the RESET pin. Reset pulses longer than 50 ns will generate

a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset.

XTAL1

Input to the inverting oscillator amplifier and input to the internal clock operating circuit.

XTAL2

Output from the inverting oscillator amplifier

AVCC

This is the supply voltage pin for the A/D Converter. It should be externally connected to V

via a low-pass filter. See

Datasheet for details on operation of the ADC.

AREF

This is the analog reference input for the A/D Converter. For ADC operations, a voltage in the range 2.7V to AVCC must be

applied to this pin.

AGND

If the board has a separate analog ground plane, this pin should be connected to this ground plane. Otherwise, connect to

GND.
