C8051T62x/T32x USB Microcontrollers

Silicon Labs’ USB Microcontrollers (MCUs), contain an embedded full-speed USB 2.0, best-in class analog peripherals and a high performance CPU. In addition, USBXpress development kits are available to provide a complete host and device software solution.

The C8051T62x/T32x EPROM-based memory family is ideal for cost-sensitive applications requiring robust analog and digital peripherals and high performance processing capabilities. The USB MCUs feature an on-board, fully integrated universal serial bus (USB) 2.0, function controller and transceiver. No external resistors, crystal or voltage regulator are required. Best-in-class, on-chip analog peripherals include a multi-channel high performance ADC up to 500 Ksps, comparators and internal voltage reference (non-ADC versions are also available).

Some members of the C8051T62x/T32x family are pin and code compatible with the C8051F32x flash-based devices offering a migration path for cost-sensitive applications.

Customers may use their own vendor ID (VID) or they may use the silicon Labs VID for USB products. If the Silicon Labs VID is used, the customer must request a unique product ID.

USB Design Considerations

Choosing the right USB communications option depends on several factors, and each solution has different requirements and degrees of flexibility for both the developer and end-user. Download this white paper to determine the easiest, most cost-effective way to add USB communications to new designs or a legacy system.

USB Connectivity in a Complex World
Although USB connectivity has become a key requirement for many embedded applications, in most cases, it is just one of several design requirements for a typical application. Read this white paper to find an easier path to achieving USB connectivity that also provides the performance and analog capabilities required to enable you to cost-effectively achieve your design goals.

USB Simplified
USB has become an enormous success in industrial and commercial applications as it continues to replace many legacy serial connections (i.e. RS-232, 485). However, for embedded solution designers, adding USB requires expert knowledge of the USB protocol, exhaustive software development and significant design time. Silicon Labs offers an easier way to retrofit existing systems using USB bridge devices. Read the white paper to find out how.
