614, lajpat rai market (mehta bros) gave me a L serios of 8535 and I had to spend 2 weekends to realize it runs only on +2.5 volts while my programer was trying it with 5. the programming was tweaked to send +2.1v and then both avrdude and avr-prog were happy. It was real hard work to just let the programing even tell me that they found the chip. the limitation only is that atmega8535L can only run on a max 8mz crystal unlike 16mhz max for a general ATmega8535.
