But for how long from now? Anyway, it’ll cost much more than, say, a Cortex M0+ processor. And if you need one of the gazillion formerly existing pinouts (like the LPC9xx series from NXP), you’re out of luck.

Ten years ago the 8051 was already painfully obsolete, PIC was getting pushed that way by Atmega (Microchip buying Atmel was a Roald Dahl twist), and inexpensive ARM dev boards like the STM32 VL Discovery board with an STM32F100 were not quite the price of a coffee like now but not quite the price of a Chinese takeaway lunch.
