32X block diagram

The 32X is made up of the following parts:

• MEGA Drive I/F Component (I/F chip built-in)
• 32X Cartridge
• SH2
• SDRAM (2 Mbit)
• Frame Buffer (1Mbit x 2)
• VDP
• Color Palette Component (VDP chip built-in)
• PWM Component (I/F chip built-in)

These hardware resources (excluding the SH2 and SDRAM components) contained by 32X are directly controlled by the MEGA Drive 68000 CPU. The ROM cartridge can be read from both the MEGA Drive and 32X. Images and sound made by 32X are combined with images and sound made by the MEGA Drive.
