Debug support for Infineon’s Audo Future
13 February 2008
Debug and test support is available for Infineon’s TC1736, TC1767 and TC1797 32bit microcontrollers in the Audo Future family.
German company pls Programmierbare Logik & Systeme’s Universal Debug Engine (UDE) 2.4 is optimised for the special features of the new microcontrollers. The TC1736, TC1767 and TC1797 all feature an increased clock frequency of up to 180MHz and 5V compatible I/O interfaces. There are also new peripheral components, such as the TC1797’s integrated FlexRay controller.
The Audo Future family offers a new debug interface. The Device Access Port (DAP) allows debug communication over two-wire or three-wire interface. With up to 80MHz clock rate, this allows significantly higher transmission rates than over previous JTAG interfaces. Three-wire with two differential data lines is claimed to achieve maximum performance and signal integrity. The pls Universal Access Device 2 (UAD2) family immediately supports the new debug interface with new firmware and a new cable to the target system.
For the two emulation devices, TC1767ED and TC1797ED which have integrated on-chip emulators, data such as instruction counter, cache hits and misses separate for program and data, interrupts, stall and idle cycles can be recorded and analyzed.
The UDE 2.4 is already being used by Infineon and selected key customers for application development.
