AT90S4433 (Atmel AVR series, 8 MHz (8 MIPS)) 4 Kbyte ISP flash, 128 bytes SRAM, 256 bytes EEPROM, two Timers, 6ch ADC, UART, PWM, WDT with Internal RC Oscillator and more.

MR-Servo Board is a small pre-assembled R/C (Radio Control) servo controller, which has 16 R/C servo connectable I/O pins. The MR-Servo Board can control up to 8 R/C servos at the same time. The MR-Servo Board uses an AT90S4433 (Atmel AVR series) CPU chip as a microcontroller. The AT90S4433 has a 4K bytes In-System Programmable Flash memory, 128 bytes SRAM, 256 bytes EEPROM and many other peripherals. The user can download a program to the board without a ROM Writer using the ISP function. A free C-compiler (Microrobot AVR GCC) is provided.
