AT90S/LS4433

Description

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.

Pin Descriptions

VCC

GND

Port B (PB5..PB0)

Supply voltage.

Ground.

Port B is a 6-bit bi-directional I/O port with internal pull-up 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 AT90S4433 as listed

on page 73.

The Port B pins are tri-stated 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 pull-up 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 tri-stated 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 AT90S4433 as listed

on page 81.

The Port D pins are tri-stated 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.

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

Output from the inverting oscillator amplifier

AVCC is the supply voltage for Port A and the A/D Converter. If the ADC is not used,

this pin must be connected to V

. If the ADC is used, this pin should be connected to

via a low-pass filter. See page 64 for details on operation of the ADC.

AREF is the analog reference input for the A/D Converter. For ADC operations, a volt-

age in the range 2.0V to AVCC must be applied to this pin.

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

ground plane. Otherwise, connect to GND.
