CAST, Inc. R8051XC

The CAST, Inc. R8051XC is a flexible configurable, single-clock 8051 compatible IP core with 8 times more performance than legacy 80C51 (with Dhrystone v1.1 Benchmark on identical clock speed). Features: 32 I/O lines, three 16-bit Timer/Counters, compare/capture unit, 18 interrupts/4 priority levels or 6 interrupts/2 priority levels, two serial interfaces (UARTs), serial peripheral interface (SPI), I2C interface, 16 bit multiplication-division unit, multiple data pointer (one, two or eight) with arithmetic and auto-switch, 15 bit programmable watchdog timer, power management unit. Optional available: On-Chip Debug Support for Keil uVision Debugger or hooks for FS2 debug module. The R8051XC IP core can be implemented in FPGA and ASIC.
