The AT89S52 is one of the most easiest microcontrollers to work with.
The simple interface to ISP (In System Programming) allows to do any experiment with software and download the .hex file to the microcontrollers' flash just in seconds. The AT89ISP programmer from ATMEL is very easy to operate. The AT89S8253 has more flash (12K) and EEPROM. Take care of the optional RESET line during programming. For testing and experimental a simple switch is needed, for production better consider a supervisor RESET chip. Another part of former Philips now NXP with UART option for ISP is P89V51RD2. It has more options like more Flash(64K), CCU, x2, UART ISP. [http://www.nxp.com/acrobat/datasheets/P89V51RB2_RC2_RD2_4.pdf] This part is programmed with Flashmagic Tool using the serial port. You just have to provide a serial connection with MAX232 or a FTDI chip and the programming interface is easy too. The programming tool is the Flasmagic http://www.flashmagictool.com/ Have fun K.L.Angelis Yes... Also DS89C4XX from Dallas-Maxim with serial programmer..only with serial terminal.
