Does anyone have an update on the
availability of the Philips P89C51Rx2
micros? I'm trying to find other micros
with In-System Programmability (ISP)
through the UART. I've found the
P89C51Rx2 family from Philips, the
ADuC812 and ADuC824 from Analog Devices,
and the T89C51RD2 from Tecmic (now Atmel).

All of the Atmel AT89xxx chips that
I've looked at either use the SPI port
for ISP or program only in a byte-wise
mechanism, neither of which are usable.
(Steve Taylor, I've just recently
discovered my inability to use the
AT89LS53, much to my dismay.)

Can anyone point to other sources of
UART-based ISP 8K+ (16K+ preferred)
Flash-memory micros?

Thanks.
