Silicon Laboratories Announces the Highest Performance Small Form Factor MCU.

The C8051F360 MCU Offers 100 MIPS, 32 kB Flash in a 5x5 mm Package

NUREMBERG, Germany -- Silicon Laboratories Inc. (Nasdaq:SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced at Embedded World 2007 the first mixed-signal 8-bit MCU family to offer 100 MHz CPU operation in a 5x5 mm package. The C8051F360 Small Form Factor MCU family adds to Silicon Laboratories' portfolio of the most functionally dense small form factor MCUs, ideal for consumer and industrial electronics applications that require precision motion control and signal processing.

Silicon Laboratories' highly integrated C8051F360 offers customers increased functionality, providing a 2-cycle 16x16 MAC, a 2% internal oscillator and 32 kB of in-system programmable Flash memory. The C8051F360 has configurable I/O port pins and a variety of communications peripherals including crystal-less UART, SPI and SMBus. The functional density of the C8051F360 allows the engineer to work within space constraints while enhancing the performance of the end product. In addition, the C8051F360 integrates precision analog capability with a linear 10-bit 200 ksps SAR ADC and programmable DAC for measurement and control.

The C8051F360 is pin compatible with Silicon Laboratories' C8051F310 MCU family. This allows designers using these solutions to easily provide both upgraded and lower cost versions of their products without having to develop multiple hardware platforms.

The C8051F360 also has low-cost development tools that designers can begin using immediately to develop their end applications. The C8051F360DK is a full-featured development kit containing all the hardware and software required to develop an embedded system. Included with the development kit is the target board, an integrated development environment (IDE) that interfaces with the on-chip debug circuitry of the C8051F360 and an evaluation version of the Keil C51 toolchain. In addition, a ToolStickSK daughter card is available to provide a convenient, portable development tool in a USB stick format.

"Silicon Laboratories has built a leading portfolio of functionally dense, small form factor 8-bit MCUs," said Derrell Coker, vice president of Silicon Laboratories. "With the C8051F360 family, designers can use an 8-bit CPU in applications that traditionally use more expensive 16-bit MCUs and DSPs. The C8051F360 family is optimized for applications that require parameter sampling, information processing and communication functions within one embedded system."

Pricing and Availability

The C8051F360 Small Form Factor MCU family is available now with pricing beginning at $2.47 in quantities of 10K.
