PCB top side (main component side).
- Hitachi HD61747B16 - SoC processor (CPU, LCD & KB driver, ROM)
- Hitachi HD61914C- 1KByte static RAM

This fx-5200P uses the same chip set as found on other Casio machines, only differing on the ROM firmware. For instance:

- fx-4000P
SoC processor: Hitachi HD61747B38
Memory: HD61914 8kbit static RAM

- FC-200
SoC processor: HD61747B55
Memory: HD61914 1KByte static RAM.
