8051 EMBEDDED CONTROLLER

The embedded controller used in the SEC1110 and SEC1210 is an R8051XC2 from Evatronix. The R8051XC2 is a high

performance 8-bit embedded processor. The processor core is a low gate count core, with low-latency interrupt process-

ing that features:

• Single clock per machine cycle: an average of 2.12 machine cycles per instruction

• Industry standard MCS51 instruction set

• Dual Data Pointers (2 x DPTR)

The R8051XC2’s interrupt controller is closely integrated with the processor core to achieve low latency interrupt pro-

cessing, incorporating the following features:

• 13 external interrupts

• 4 priority levels for each interrupt

The embedded controller provides low-cost debug solutions, including:

• JTAG port for debugging using EASE OCDS debugging

• Software and 4 hardware breakpoints

The R8051XC2 bus interfaces include:

• 256 bytes internal data memory RAM

• Program Memory Write Mode

• Supports 128 KB program memory space with banking

• Supports 128 KB of external data memory space with banking
