The Super Accelerator 1 (SA1) chip was used in a number of SNES games, including the popular Super Mario RPG: Legend of the Seven Stars. [10]

Similar to the 5A22 CPU in the SNES console, the SA1 contains a processor core based on the 65C816 with several programmable timers. [2] The SA1 does not function as a slave CPU for the 5A22; both can interrupt each other independently. The SA1 also features a range of enhancements over the standard 65C816: Upgraded 10 MHz clock speed, up from a maximum of 3.58 MHz Faster RAM Memory mapping capabilities Limited data storage and compression New DMA modes such as bitmap to bit plane transfer Built-in CIC lockout, for copy protection and regional marketing control
