Silicon Laboratories C8051F7xx MCU Family

The C8051F7xx, from Silicon Laboratories, is a family of high pin-count MCUs for cost-sensitive, high I/O embedded systems. The C8051F7xx family offers a new, patent-pending touch sensing feature that is robust, accurate, responsive and easy to configure. The new MCUs offer up to 54 general purpose I/O pins and a 25 MIPS 8051 CPU. The C8051F7xx family is ideal for industrial controls, security systems, residential HVAC, home appliances, keyboards, cash machines, and fax/printer/scanner front panels. The C8051F700 MCU family is available now in QFP64, QFP48, and QFN48 packages with pricing beginning at $1.90 in quantities of 10K.
