MCU incorporates high-resolution conversion
The C8051F350 is precision mixed-signal microcontroller that integrates an eight-channel, 24bit ADC with a high-speed 8051-compatible CPU.
The C8051F41x also offers versatile voltage supply from 2 to 5.25V with an on-chip programmable voltage regulator and up to 5V tolerant independent I/O voltage control.
The small size of the C8051F41x makes it ideal for portable equipment, instrumentation and measurement devices, consumer medical products and industrial meters.
The C8051F41x features Silicon Laboratories' high-speed, pipelined 50MIPS 8051 core, 16 to 32Kbyte Flash memory, 2Kbyte RAM and versatile voltage range operation.

The Si3110 is heralded as the industry's smallest, high-performance, integrated analogue front end (AFE) for ADSL and ADSL2+ applications.
The C8051F41x integrates on-chip peripherals such as a 12bit 200Ksample/s analogue-to-digital convertor, two 12bit digital-to-analogue convertors, temperature sensor, programmable voltage reference and comparators.
The on-chip voltage regulator may be used to supply power to external ICs in the system making it ideal for legacy systems with high-voltage supplies as well as new battery powered systems that require low-voltage operation.
The C8051F41x integrates a 2%-accurate precision internal oscillator that eliminates the need for an external crystal or resonator.
Onboard serial communication peripherals include UART, SMBus and SPIbus serial ports.
The C8051F41x also includes a "SmaRTclock", an embedded real-time clock that enables the MCU to automatically detect power supply failures and switch to a battery backup that will allow continued operation of the backup RAM down to 1V.
The smart clock can keep time accurately and reliably and detect a clock failure, even when the MCU is sleeping, and alert the CPU so that recovery is possible.
"Silicon Laboratories' new small form factor MCUs leverage our core competency in mixed-signal design to provide customers with industry leading integration and performance", said Derrell Coker, Vice President of Silicon Laboratories.
"The combination of the increased memory, small size, versatile voltage supply and SmaRTclock make the C8051F4x ideal for a number of growing applications including XFP modules, battery-powered portable equipment, instrumentation and measurement devices".
A low cost evaluation kit (C8051F411EK) is available for evaluation of Silicon Laboratories' C, versatile voltage supply and software development tools.
A reference design kit (Voice-Record-RD) is also available for evaluation of the device's high-performance analogue and CPU throughput capability.
The C8051F41x products include on-chip debug circuitry facilitating nonintrusive, full-speed, in-circuit debugging before and after installation without requiring an emulator.
Like all Silicon Laboratories' MCU products, the C8051F41x products are also supported with a complete, professional development kit (C8051F410DK) that includes everything required to immediately begin the system design: IDE, target board, cables and power supply.
The C8051F411/3 comes in 28-pin QFN and C8051F410/2 comes in a 32-pin QFN.
Pricing begins at $2.56 in quantities of 10,000.
The professional C8051F410DK development kit is available for $99, the low cost C8051F411EK is available for a special promotional price of $29 and the reference design kit is available for $49.
