Silicon Labs C8051F38x and C8051T62x/T32x USB Microcontrollers

Silicon Laboratories introduced the C8051F38x (flash-based) and C8051T62x/32x (OTP) USB microcontroller (MCU) families. The C8051F38x and C8051T62x/32x USB MCUs are available now in space-saving 4 mm x 4 mm and 5 mm x 5 mm QFN packages. Prices start at $2.12 in 10,000-unit quantities for the F38x and $1.07 for the T62/32x. The new Silicon Labs microcontrollers are ideal for 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.
