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.
