Emulate the CDP1802 with an ARM

5 V-tolerant IOs or better 5 V supply
48 MHz clock
> 36 IOs
96 KiB Flash
- 64 KiB Flash for emulating external ROM memory
- 32 KiB emulating program
16 KiB RAM
- 8 KiB RAM for emulating external RAM memory
- 8 KiB RAM emulating program
LQFP48 package (7 x 7 mm) or QFN64 (8 x 8 mm), it has to fit between DIL40

STM most IOs are 5 V tolerant
