16-bit automotive MCUs offering 32-bit performance at 8-bit cost

Infineon has extended its 16-bit XC2000 automotive microcontroller with a low cost version offering 32 bit performance. Infineon has developed this MCU to reduce the cost of existing body (with XC2200 series), safety (with XC2300 series) and powertrain (with XC2700 series) designs in cost optimized cars.

Infineon suggests automotive suppliers single microcontroller platform such as this for wider product offerings with increased performance range. The targeted applications of this new XC2000 include low-cost body control modules (BCM), low-cost airbags or low-end engine management electronics.

"The new XC2000 devices with 32-bit equivalent performance at 8-bit prices complete the industry's most scalable 16-bit MCU portfolio, addressing the diverse needs of automotive system suppliers from emerging markets to luxury class. Infineon gives the medium-sized and compact car category access to the safety and convenience applications of the premium segment," said Peter Schaefer, Vice President and General Manager, Microcontrollers, Infineon Technologies AG. "Our customers can select the most appropriate devices with cost optimized peripherals and re-using existing software across a complete family, exactly fulfilling their design needs and market requirements."

Key features of the new cost-optimized XC2000 MCU devices include:

1. Based on a high-performance C166SV2 CPU with 5-stage pipeline offering a Multiply Accumulate     (MAC) unit with DSP functionality for dedicated filter algorithms.
2. Peripherals include two CAN nodes, up to four flexible serial interfaces and up to 19 AD converter     (ADC) channels.
3. Offers high-speed 12-bit ADC with a fast conversion time of less than 1 µs.
4. Has an integrated window watch dog with independent clock reduces the demand of external      components for automotive applications.
5. Features on-chip power supply, power control and debug support.
6. Offered with flash capacities of 32KB, 64KB, 96KB and 160KB, which expands the scalability of the      whole XC2000 family from 32KB to 1.6MB flash memory.
7. 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.

Rounding off into the low-end: New derivates of XC2200 (body), XC2300 (safety) and XC2700 (powertrain) series

The XC2200L series, with the XC223xL (LQFP-64) and XC222xL (VQFN-48) derivatives further enlarges the XC2200 microcontroller family to the low-end offering memory sizes of 64KB to 160KB Flash and up to 12KB RAM. The XC2200L microcontrollers were developed for use in cost-sensitive body applications. The devices provide up to 60 MIPS peak performance with a 66MHz CPU clock.

The XC2200U series, with the XC222xU (VQFN-48) and XC221xU (TSSOP-38) variants address the 16-bit entry-level segment. With up to 40MHz and a memory size of 32KB to 64KB Flash and up to 8KB RAM, the microcontrollers of this series are well suited for the 8-bit body application segment.

The XC2300D series, with the XC233xD (LQFP-64) and XC232xD (VQFN-48) derivatives operate up to 66MHz. With up to 160KB Flash and 12KB RAM and dedicated peripherals they are ideal for low-cost safety applications.

The XC2300S series, with the XC232xS (VQFN-48) and XC231xS (TSSOP-38) variants address the entry-level 16-bit segment. With up to 40MHz and a maximum memory size of 64KB Flash and up to 8KB RAM, the XC2300S microcontrollers are well suited to start with a 16-bit MCU in the very low-end 8-bit safety application segment.

The XC2700 series, with the XC2733X (LQFP-64) and XC2723X (VQFN-48) derivatives operate up to 40MHz. With up to 160KB Flash and up to 12KB RAM they are an ideal solution for the cost-sensitive powertrain segments including 2- and 3-wheel vehicle applications. With a maximum memory size of 64KB Flash and up to 8KB RAM the XC2722X (VQFN-48) and XC2712X (TSSOP-38) series address e.g. cost-optimized control of advanced auxiliaries (fans, pumps, etc.).

Availability: Engineering samples of the new low-end 16-bit XC2000 automotive microcontrollers are available with volume production scheduled for mid of 2011.
