core combines rich instruction with general purpose working registers. registers directly connected Arithmetic Logic Unit (ALU), allowing independent registers accessed single instruction executed clock cycle. resulting architecture more code efficient while achieving throughputs times faster than conventional CISC microcontrollers. ATmega8535 provides following features: bytes In-System Programmable Flash with Read-While-Write capabilities, bytes EEPROM, bytes SRAM, general purpose lines, general purpose working registers, three flexible Timer/Counters with compare modes, internal external interrupts, serial programmable USART, byte oriented Two-wire Serial Interface, 8-channel, 10-bit with optional differential input stage with programmable gain TQFP package, programmable Watchdog Timer with Internal Oscillator, serial port, software selectable power saving modes. Idle mode stops while allowing SRAM, Timer/Counters, port, interrupt system continue functioning. Power-down mode saves register contents freezes Oscillator, disabling other chip functions until next interrupt Hardware Reset. Power-save mode, asynchronous timer continues run, allowing user maintain timer base while rest device sleeping. Noise Reduction mode stops modules except asynchronous timer ADC, minimize switching noise during conversions. Standby mode, crystal/resonator Oscillator running while rest device sleeping. This allows very fast start-up combined with low-power consumption. Extended Standby mode, both main Oscillator asynchronous timer continue run. device manufactured using Atmel's high density nonvolatile memory technology. On-chip Flash allows program memory reprogrammed In-System through serial interface, conventional nonvolatile memory programmer, On-chip Boot program running core. boot program interface download application program Application Flash memory. Software Boot Flash section will continue while Application Flash section updated, providing true Read-While-Write operation. combining 8-bit RISC with In-System Self-Programmable Flash monolithic chip, Atmel ATmega8535 powerful microcontroller that provides highly flexible cost effective solution many embedded control applications. ATmega8535 supported with full suite program system development tools including: compilers, macro assemblers, program debugger/simulators, InCircuit Emulators, evaluation kits.
AT90S8535 Compatibility ATmega8535 provides features AT90S8535. addition, several
features added. ATmega8535 backward compatible with AT90S8535 most cases. However, some incompatibilities between microcontrollers exist. solve this problem, AT90S8535 compatibility mode selected programming S8535C fuse. ATmega8535 compatible with AT90S8535, replace AT90S8535 current Printed Circuit Boards. However, location fuse bits electrical characteristics differs between devices. AT90S8535 Compatibility Mode Programming S8535C fuse will change following functionality: timed sequence changing Watchdog Time-out period disabled.

First Analog Comparator conversion delayed Asynchronous Oscillator does stop Power-down First Analog Comparator conversion delayed device powered slow rising VCC, first Analog Comparator conversion will take longer than expected some devices. Problem Fix/Workaround When device been powered reset, disable then enable Analog Comparator before first conversion. Asynchronous Oscillator does stop Power-down asynchronous oscillator does stop when entering Power-down mode. This leads higher power consumption than expected. Problem Fix/Workaround Manually disable asynchronous timer before entering Power-down.
