Silicon Laboratories introduce two USB MCU families for range of apps

Silicon Laboratories Inc has introduced two new C8051F38x and C8051T62x/32x USB MCU families for applications such as home automation systems, thermostats, USB dongles, smart card readers, GPS localizers, touch panels, sensor data loggers, portable medical devices, weigh scales, USB speakers, serial communication bridges, games and electronic toys.

Silicon Labs developed the new USB MCU families to simplify the addition of USB connectivity to embedded designs. The families, which include 22 products with flash and one-time-programmable (OTP) options, feature a full-speed USB 2.0 interface engine, analog functionality, and clock recovery capability to enable crystal-less USB operation for reduced component count and BOM cost.

The flash-based F38x devices are pin- and code-compatible with Silicon Labs' existing C8051F34x USB MCUs for easy migration while offering an additional I2C interface, a higher performance analog-to-digital converter (ADC), lower power consumption and additional timers.

The F38x and T62x/32x families feature on-chip ADC and high-speed comparators to ease the development of analog-intensive applications such as sensor data loggers, weigh scales, gaming controls and blood pressure monitors.

"We continue to see strong demand for our USB solutions because we enable easy, cost-effective USB connectivity better than any other MCU supplier," said Mark Thompson, vice president of Silicon Labs' Embedded Mixed-Signal products. "The combination of our high-performance processing cores, crystal-less operation and precision analog functionality simplifies embedded designs and reduces component count and BOM cost without sacrificing performance."

Package: QFN
Availability: Now
Price: Begins at $2.12 in 10,000-unit quantities for the F38x flash-based devices and $1.07 for the T62/32x OTP MCUs.
