Mixed-Signal Microcontroller – for precision measurement applications

Silicon Laboratories Inc announced the newest member of the company's precision mixed-signal microcontroller (MCU) product family, the C8051F350 , which integrates an eight-channel, 24-bit analog-to-digital converter (ADC) with a high-speed 8051-compatible CPU.

Available in a small 5×5 mm package, the highly-integrated C8051F350 is 30% smaller than competing solutions. Based on the industry's fastest 8051 CPU, the C8051F350 delivers up to 50 MIPS throughput with a 50 MHz clock. The combination of high-precision analog data conversion, high-speed data processing, in-system programmability and small size makes the C8051F350 the ideal choice for precision measurement applications, such as weigh scales, process control and smart sensors.

The ADC has programmable analog data conversion rates up to 1,000 conversions per second and is complemented by dual 8-bit sensor-excitation digital-to-analog converters and an on-board temperature sensor. The C8051F350 has 17 flexible digital I/O pins that are 5 V compatible. On-board serial communication peripherals include UART, SPI and SMBus serial ports. The MCU also incorporates a precision internal oscillator eliminating the need for an external crystal or resonator.

As with all of Silicon Laboratories' MCU products, the C8051F350 features in-system debugging that eliminates the need for an emulator. It is supported with a complete, low-cost professional development kit that includes everything required to immediately begin the system design: IDE, target board, cables and power supply.

Silicon Laboratories offers the C8051F350 packaged in a 32-pin LQFP or a 28-pin MLP. Pricing begins at $4.38 in quantities of 10,000. The C8051F350 development kit is available now for $129.
