EEMBC Benchmarks Infineon’s XC167CI Flash Microcontroller

Device is First 16-Bit Chip to Face Off With Consortium’s Microcontroller Suite

EL DORADO HILLS, Calif.—January 15, 2004—The first certified score for a 16-bit device to be tested against the EEMBC 8-/16-bit Microcontroller benchmark suite was announced today by the Embedded Microprocessor Benchmark Consortium with the publication of benchmark results for Infineon’s XC167CI flash microcontroller.

In out-of-the-box benchmark tests using the Keil V4.27 compiler, the 40-MHz XC167CI achieved a MicroMark™ score of 5631 based on its performance in a range of automotive/industrial benchmark kernels tailored for 8- and 16-bit devices. Components of the MicroMark score include device performance in bit manipulation, memory access, pointer chasing, PWM, response to remote request (CAN), road-speed calculation, and tooth-to-spark.

The 8-/16-bit Microcontroller benchmarks also include a hand-coded, task-based benchmark suite that performs memory transfers, a checksum calculation, multiplication, UART data transfers, and shift operations typical of CRC and encryption algorithms, for which the XC167CI achieved a score of 474 iterations per second. These certified scores can be put into perspective by viewing other published scores on the EEMBC Web site.

EEMBC President Markus Levy stated: “Although 8- and 16-bit microcontrollers are oftentimes recognized for their wealth of on-chip peripherals, performance is critical for many applications. EEMBC’s Microcontroller benchmark suite is a valuable tool for evaluating the behavior of a microcontroller whether it is running at 32 kHz or 40 MHz.”

Built using Infineon’s C166V2 core and manufactured in a 0.22-micron process, the XC167CI features a five-stage pipeline that yields a twofold performance increase in comparison with Infineon’s C167 microcontroller. On-chip features of the XC167CI include a 128-kilobyte advanced program flash memory, a multiply-accumulate unit, a 16-priority-level interrupt system on eight group levels, up to 103 I/O lines, a twin CAN interface, two 16-bit capture-compare modules, and a PWM unit for motor control applications.

“The XC167CI is the newest member of the popular C166 microcontroller family, which has a 10-year history of successful deployment and extensive applications support,” said Stefan Wierzoch, senior marketing manager for Automotive and Industrial Microcontrollers at Infineon. “Based on the enhanced C166V2 architecture, the new-generation MCU doubles CPU performance compared with its predecessors. Impressive DSP performance and advanced interrupt handling combined with a powerful, integrated peripheral set and high-performance, on-chip flash or ROM memory make the XC167CI the instrument of choice for industrial and automotive applications.”
