The AT90S8515 is a low voltage (2.7V - 6V), high performance CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. A rich instruction set is combined with 32 general purpose working registers. Each register is connected to the ALU, allowing two independent registers to be accessed in a single instruction. This allows additions, subtractions, comparisions to be completed in a single clock cycle. The AT90S8515 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.
The AT90S8515 provides the following features:
~ 8K bytes of Flash Memory ~ 512 bytes of EEPROM! ~ 512 bytes of Internal Ram ~ 32 I/O lines ~ one 8 bit timer/counter ~ one16-bit timer/counter ~ Programmable Serial UART ~ Dual 10 bit PWM ~ Analog Comparator ~ 8051 Pin Compatible
In addition, the AT90S8515 is designed with static logic for operation down to zero frequency. Also, the I/O lines have programmable internal pull up resistors which can be individually enabled for greater flexibility.
