ColdWatt Selects Silicon Laboratories' Small Form Factor MCUs

April 02, 2007

AUSTIN, Texas--(BUSINESS WIRE)--April 2, 2007--Silicon Laboratories Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, and ColdWatt Inc., a manufacturer of high-efficiency power conversion products, today announced that ColdWatt has chosen Silicon Laboratories' C8051F30x Small Form Factor MCU. The functionally dense C8051F30x combines a fast 25 MIPS 8051 CPU, Flash memory and precision analog in a 3x3 mm quad flat no-lead package. ColdWatt selected the high-performance C8051F30x for its flexible, energy efficient, digital power conversion platforms.

Silicon Laboratories' highly integrated mixed-signal MCUs eliminate several external components such as crystal oscillators and comparators. The small size and fast CPU operation of the C8051F30x make it ideal for space-constrained, power-efficient, high-performance industrial, wireless and consumer applications. The C8051F30x helps ColdWatt's modular digital power conversion platforms deliver up to 91 percent power conversion efficiency with power levels ranging from 650-1200 W.

"Silicon Laboratories' MCUs offer a lot of functionality in a very small size to enable us to develop highly efficient power conversion platforms," said Allen Rozman, vice president of engineering at ColdWatt. "By implementing the easy-to-use C8051F30x, we were also able to speed our time to market."

Development with the C8051F30x is quick and easy due to low-cost professional development tools. In addition, the C8051F30x includes on-chip 2-wire (C2) debug circuitry that provides non-intrusive, full-speed in-circuit debugging of the production part before and after installation without an emulator. The pipelined 8051 instruction set also provides over ten times the throughput when compared with other solutions.

"The C8051F30x offers unprecedented levels of integration, performance and functionality," said Derrell Coker, vice president of Silicon Laboratories. "Our Small Form Factor MCUs are redefining the 8-bit market to offer industry-leading combinations of size, speed and high-performance peripherals."
