CAST C8051
The C8051 processor core is a single-chip, 8-bit microcontroller that executes all ASM51 instructions and has the same instruction set and timing of the 80C31. The microcode-free design was developed for reuse in ASICs and FPGAs. It is strictly synchronous, with positive-edge clocking (except for a flip-flop for internal reset and two flip-flops for gated clocks in the PMU), no internal tri-states and a synchronous reset.| Part No. | C8051 |
