Silicon Labs - mixed-signal MCUs
Smallest automotive communications controller for body electronics
Silicon Laboratories announced the industry’s smallest automotive
communications controller. The C8051F50x family of mixed-signal MCUs is
the first to integrate an ultra high-performance internal precision
oscillator to support both CAN and LIN communication networks without
an external crystal or resonator. Silicon Labs’
highly-integrated, mixed-signal MCUs are ideal for applications where
end-product size is critical such as window lifters, seat positioning
and steering angle sensing.
The C8051F50x family provides the highest functional density for
automotive applications by integrating a 50 MIPS core, up to 64 kB of
high-endurance Flash, four kB of RAM, 32-message buffer CAN 2.0B
hardware controller and a hardware LIN 2.0 controller in a 5 x 5 mm2
package, providing customers with the memory and computational
resources for real-time applications requiring CAN and LIN software
stacks. The 50-MHz instruction clock provides up to five times better
8-bit CPU throughput than the competition, offering 16-bit class
performance at a lower system cost. The internal precision oscillator
provides an accuracy of ±0.5 percent across the entire
temperature (-40 to +125 ºC) and voltage (1.8 to 5.25 V) range,
insuring the four-corner operation that Silicon Labs’ customers
have come to expect.
By integrating world-class analog on-chip, Silicon Labs provides a
number of advantages. The integrated 12-bit, 200 ksps, 32-channel
analog to digital converter (ADC) has the highest signal-to-noise ratio
(SNR) than any other integrated MCU device in this space, offering
higher precision and accuracy when simultaneous analog and digital
processing is required. Analog performance is further enhanced through
the inclusion of a precision voltage reference, typically not found on
integrated solutions. The programmable comparator can be dynamically
re-mapped to different I/O pins during run-time providing a simple but
powerful solution for motor commutation. Additionally, the integrated
temperature sensor provides an internal mechanism for diagnostics and
system calibration.
“Increasing reliance on electronics to develop more efficient,
safer and more full-featured automobiles is driving demand for
cost-effective, high-performance, mixed-signal solutions,” said
Derrell Coker, vice president and general manager. “With the
addition of this new family of automotive 8-bit MCUs, we’re able
to provide customers with a portfolio that further simplifies in-car
communication networks while enabling new features.”
Silicon Labs delivers industry-leading, low cost tools to help speed
design and accelerate market entry. A complete, low-cost professional
development kit is available for all family members and includes
everything required to immediately begin system design including IDE,
target board, cables and power supply. An inexpensive ToolStick
daughter card, base adapter and programming card are also available.
All members of the C8051F50x family are available in 32-pin and 48-pin QFN and QFP packages.
Silicon Labs is an ISO/TS-16949 registered company, and all of the company’s automotive products are AEC-Q100 qualified.
