On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
- Provides breakpoints, single stepping,
inspect/modify memory and registers
- Superior performance to emulation systems using
ICE-chips, target pods, and sockets
- Low cost, complete development kit
High-Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of
instructions in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
