It runs at 8 MHz and carries 16 KB of on-chip Flash program memory along with 1K x 8 of RAM.
8 MHz is the core clock speed. On an 8-bit HC08 architecture that means you get roughly 8 MIPS — enough for sensor polling, simple PID loops, LIN or SCI messaging, and basic human-machine interface tasks. It is not a part for heavy math or fast data logging; the 1K x 8 RAM puts a hard ceiling on buffering.
Yes, the oscillator type is Internal, so no external crystal or resonator is required for basic operation.
The order code MC908GR16VFAE includes the suffix VFAE which specifies the 48-LQFP package and -40°C to 105°C temperature range. MC908GR16 without the suffix is a generic family designation — the exact equivalent depends on the package and temperature grade required. For a drop-in replacement, match the full order code.
