Infineon extends XC2000 automotive microcontroller family

June 21, 2011 // By Christoph Hammerschmidt
Giving the medium-sized and compact car category access to the safety and convenience applications of the premium segment and enabling their compliance with the strictest fuel consumption and pollutant emission requirements, Infineon has introduced a cost-optimized extension of its successful XC2000 automotive microcontroller portfolio. The company promises 32-bit equivalent performance at 8-bit costs.

The 16-bit XC2000 devices address low-end and ultra-low-cost automotive applications and support cost reductions of existing body (with XC2200 series), safety (with XC2300 series) and powertrain (with XC2700 series) designs. With this family extension, Infineon in particular assists automotive system suppliers that seek to broaden offerings towards a wider performance range without introducing multiple microcontroller platforms. Infineon's approach provides scalable automotive solutions with a high degree of hardware and software reuse that achieves significant cost savings.

Typical applications addressed by the new XC2000 16-bit devices include low-cost body control modules (BCM), low-cost airbags or low-end engine management designs. To further optimize the PCB size Infineon offers its new XC2000 devices in cost-optimized and very small packages.

The new members of the XC2000 family are based on a high-performance C166SV2 CPU with 5-stage pipeline. The products offer a Multiply Accumulate (MAC) unit with DSP functionality for dedicated filter algorithms. In addition, they provide an optimized peripheral set for low-cost applications with up to two CAN nodes, up to four flexible serial interfaces and up to 19 AD converter (ADC) channels. The high-speed 12-bit ADC provide a fast conversion time of less than 1 µs. An integrated window watch dog with independent clock reduces the demand of external components for automotive applications. On-chip power supply, power control and debug support enable an easy design. The devices are offered with flash capacities of 32 KB, 64 KB, 96 KB and 160 KB, which expands the scalability of the whole XC2000 family from 32 KB to 1.6 MB flash memory. An optimized PIN-out results in an increased number of available I/Os with up to 49 I/Os within a 64-pin package. In addition, Infineon offers derivates in cost optimized packages like VQFN-48 with small dimensions of 7-mm x 7-mm for footprint critical applications.

The XC2200L series, with the XC223xL (LQFP-64) and XC222xL (VQFN-48) derivatives enlarges the XC2200 microcontroller family to the low-end offering memory sizes
