The bootloader I may have to provide would be RS232 but that could b...

We would like to know of micros that have UART bootloaders loaded at the factory so that the parts can be programmed in system from a serial port on the test computer. Requirements are simple: 8 bit ADC, a few timers for PWM. Cost is
