We are looking for a microcontroler with 4 PWM outputs and 2 serial ports. Microchip has a new device (PIC18F6620)wich is perfect for our application..., but this product is not yet released to production!

Please help us finding the miraculous chip.

Thanks

 

Try GE Fanuc IC200UDD110.

 

Check out "www.infineon.com":http://www.infineon.com and look for 8-bit microcontrollers i think there is a MCU C515c-L that should have 4 PWM outputs. It is a 8051 derivative.

Good Luck!!

Try Atmel Atmega128 , has 8 independent PWM outputs, 2 independent USART's , 1 SPI/2 wire interface, 128kB in circuit programmable flash,
4kb of ram and is available in industrial temp range.

Otherwise, use whatever micro you prefer with 4 PWM outputs and an SPI interface and add to it any number of Maxim Max3110 ( UART chips) to
obtain the number of serial ports you need. These talk SPI in/out to the micro and both TTL level and RS232 level rs232 to the serial link, have a
fifo buffer , low power, and low cost .

Try MSP430F149 from Texas Instrument. It is much cheaper than Microchip and has all you need.
