I'm hoping to identify more micros similar to Atmel AT89C51cc003 - by this I mean micros that ship with a boot loader and can be programmed serially via CAN/LIN/ASYN with a single pin selection (PSEN) or micros like the zilog Z8 that can be programmed and debugged with just GND and DBG BUT - in automotive grade. Thanks

Many STM32 devices can be programmed via CAN. All of them can be programmed via UART (as far as I know).

1 | 5.2 External Signal Description |
2 | A single-wire interface pin called the background debug interface |
3 | (BKGD) pin is used to communicate with the BDM system. During reset, |
4 | this pin is a mode select input which selects between normal and |
5 | special modes of operation. After reset, this pin becomes the |
6 | dedicated serial interface pin for the background debug mode. |
