Block Diagram
The AVR core combines a rich instruction set with 32 gen-
eral 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 through-
puts up to ten times faster than conventional CISC micro-
controllers.
The AT90S4434/8535 provides the following features:
4K/8K bytes of In-System Programmable Flash, 256/512
bytes EEPROM, 256/512 bytes SRAM, 32 general purpose
I/O lines, 32 general purpose working registers, RTC, three
flexible timer/counters with compare modes, internal and
external interrupts, a programmable serial UART, 8-chan-
nel, 10-bit ADC, programmable Watchdog Timer with inter-
nal oscillator, an SPI serial port and three 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. In Power Save mode, the timer
oscillator continues to run, allowing the user to maintain a
timer base while the rest of the device is sleeping.
The device is manufactured using Atmel’s high density
non-volatile memory technology. The on-chip ISP Flash
