Description
Atmel AT90S8535-8JI IC Microcontrollers 8-BIT, FLASH, 8MHz, RISC , PQCC44, PLASTIC, MS-018AC, LCC-44
The is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the AT90S4434/8535 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AT90S4434 has 4K bytes of In-System Programmable Flash, 256 bytes of EEPROM, and 256 bytes of internal SRAM. The AT90S8535 has 8K bytes of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of internal SRAM. Table 1 summarizes the different memory sizes for the two devices.
