The C8051F39x/7x MCUs are based on a patented, pipeline 8051 core that provides 2.5x faster CPU performance (up to 50 MIPS) than competing devices. Finer resolution pulse-width modulation (PWM) offers the ability to execute more complex algorithms, enabling a greater range of motor speeds and higher efficiency in motor control applications. Support for four interrupt priorities allows fast interrupt handling for real-time applications.Addressing the industry need for low-power operation and green energy compliance, the C8051F39x/7x MCUs are designed to consume an ultra-low 160 µA/MHz in active mode, enabling up to an 80 percent power savings compared to competing devices. Low-power active mode is vital for portable applications to extend battery life and for space-constrained and enclosed applications such as optical transceiver modules to minimize self-heating. The C8051F37x devices are the first Silicon Labs MCUs with 512B of EEPROM, supporting ten times more write/erase cycles (1M vs. 100k typical) and faster programming times (3.5 ms vs. 112 ms) compared to standard flash implementations. These increased write/erase cycles are useful for applications such as wireless sensor nodes and data loggers that must constantly write to memory. The faster programming times often are needed for applications such as industrial controls and optical modules that require tight calibration loops. “The new C8051F39x/7x MCUs leverage our mixed-signal capabilities to provide enhanced on-chip analog peripherals such as our high-precision temperature sensor without compromising product cost, performance or size,” said Mike Salas, vice president and general manager of Silicon Labs’ microcontroller products. “Our customers are faced with the need to pack more functionality in smaller footprints, and we excel at architecting MCUs that deliver the utmost in computational throughput, integration, power efficiency and analog performance.” Comprehensive Development Kits Silicon Labs’ development kits for the C8051F39x/7x MCU family provide everything embedded developers need to evaluate hardware and develop code including C8051F390 or C8051F370 target boards, USB debug adaptor/programmer, power supply, cables, quick-start guide and complimentary downloadable software tools. Silicon Labs’ TOOLSTICK370-A-DC daughter card provides a cost-effective, easy-to-use development system that enables designers to develop and debug application firmware directly on the target C8051F39x/7x MCU using the Silicon Labs Integrated Development Environment (IDE).
