Infineon Technologies AG has extended its XC2000 automotive microcontroller portfolio in an effort to provide 32-bit equivalent performance at 8-bit costs. The 16-bit 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.
Typical applications addressed by the latest XC2000 16-bit devices include low-cost body control modules (BCM), low-cost airbags or low-end engine management designs.
The latest additions are based on a C166SV2 CPU with 5-stage pipeline and provide a multiply accumulate (MAC) unit with DSP functionality for dedicated filter algorithms.
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 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 32KB, 64KB, 96KB and 160KB, which expands the scalability of the whole XC2000 family from 32KB to 1.6MB flash memory.
There is 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 further enlarges the XC2200 microcontroller family to the low-end offering memory sizes of 64KB to 160KB flash and up to 12KB RAM. 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 suitable 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 such as cost-optimized control of advanced auxiliaries including fans and pumps.
Engineering samples of the low-end 16-bit XC2000 automotive microcontrollers are available with volume production scheduled for mid of 2011.
