V8 is not designed to run such severely constrained platforms. Basically
it's targeted at "smartphone or better".
Do you even have an operating system on that platform? AFAIK even a minimal
embedded Linux kernel needs >=2MB of RAM to boot. Without modifications, V8
requires an operating system to run (Linux/OSX/Windows are officially
supported; {Open,Free,Net}BSD and Solaris seem to work too); it does not
have bare-metal support.
Even more importantly: IIUC, the STM32 and all other ARM Cortex-M based
chips don't support the regular ARM instruction set, which V8's ARM port
uses. That means you'd have to create a port of the platform-specific parts
of V8 first (which, as a rough guess, is a few man-years of work).
If I had to program a chip with 200KB of RAM, I'd probably do it in C...
