The DProbeCR16C emulator concept is based on the latest FPGA and ASIC-technology. The handheld size and its modular upgrade capability make this development tool a valuable help for any design engineer. The DProbeCR16C is available in several variants for different families of SC14xxx DECT based derivatives from National Semiconductor. This guaranties that all derivative specific properties are emulated in the correct way. Different processor boards are available to change to a new derivative within a specific family. Various adapters are available to easily switch to another package. To make a change from one derivative family to another easy and with low cost, the add-on DBox16 is universal for all derivatives and can also be used with other architectures. The extended features of DBox16 make this product a high-end in-circuit emulator for the professional system engineer.
Outstanding is the Rias feature which provides additional debugging capabilities.

At the moment several processor boards for the emulation of the following SC14xxx derivatives are available:

• SC14428, SC14429 and other CR16C based SC14xxx derivatives with Nexus debug interface

The DProbeCR16C in-circuit emulator is dedicated to support specific SC14xxx derivatives with Nexus debug interface. Maximum benefit can be obtained with the full functional feature set available:

• Small high-end real-time in-circuit emulator, non-intrusive
• Supports up to the maximum operating frequency without wait-states
• Excellent price / performance ratio
• Modular system, no overhead
• Easy emulation processor setup
• Interrupt support while emulation is halted (planned)
• Watchdog support
• Full DIP debug support
• GENDSP support
• Support of FLASH programming (planned)
• Support for 2 and 3 cell mode
• 2 MB dual-ported emulation memory, on-the-fly access to variables
• 1M software breakpoints for code located in the emulation memory
• Virtually unlimited number of software breakpoints for code located in the target RAM
• 8 complex hardware breakpoints for code, data read or data write for the complete 16 MB address range
• Rias (with DBox16)
• Trace and Trigger to on-chip resources using bondout technology (with DBox16)
• Macro language HiSCRIPT
• Support for all popular compilers (IAR, National Semiconductor)

For more emulation features, the DProbeCR16C functionality can be expanded by the universal module DBox16.
