Hello, I have got question: why generally 16 bit microcontrollers are not popular like 8 or 32 bit?

On the contrary, MSP430s are quite popular.

It is not a popularity contest.

Mainly I think because 32-bit solves a lot of problems related to math and address space.

Also, what characterizes a 16 vs 32-bit MCU? The Cortex-M uses a 16-bit wide instruction set. What about the Motorola 68000?
