CAST, Inc. R8051 Core

The CAST, Inc. R8051 Core is a Fast, small, single-chip, 8-bit microcontroller that executes all ASM51 instructions. It has the same instruction set as the 80C31, but its RISC- like design executes operations an average of 8 times faster. The R8051 provides software and hardware interrupts, a serial communications interface, two timers, and Intel peripherals support. On-chip debugging is an option.
