Supported Operating Systems: 8051
Supported 8-bit Architectures: 8-bit, 8051

The C8051F3xx USB MCU family includes a USB 2.0 function controller with an integrated transceiver and on-chip clock recovery. No external resistors, crystal, voltage regulator, EEPROM or other components are required. On-chip resources include a high-speed 8051 CPU with up to 64 kB Flash, UARTs, I2C, SPI, timers, counters and PWM generators. On-chip analog features include a multi-channel 10-bit ADC, precision voltage reference, internal oscillator, comparators and a temperature sensor.

FEATURES & BENEFITS

• A single-chip solution for embedded USB applications
• 10-bit ADCs with programmable throughput up to 200 ksps, ±1 LSB INL with no missing codes
• ADCs also feature up to 17 external inputs that can be programmed to operate in single-ended or differential mode
• Other analog peripherals include two comparators, built-in temperature sensor and internal precision voltage reference
• High level of integration results in small package sizes, saving board space and reducing overall system cost

Silicon Laboratories’ development kits include advanced debug features enabling the user to fully develop and integrate hardware and software design. Since the MCU has built in debug capabilities, it can be installed into the end application. This development system is not encumbered with sockets, target cables or “ICE Chips.” The development kit supports the following debug features: Run, halt and single-step, set hardware breakpoints, inspect/modify memory and registers, download program memory.

TECHNICAL SPECS

• USBXpress Development Software provides a complete host and device software solution, including Microsoft Windows device drivers

• No USB protocol or hardware expertise is required. A simple, high-level API is used on both the host and USB MCU to achieve high-performance USB connectivity
• USBXpress Development Software includes royalty- free, Microsoft-certified device drivers, INF driver installation files, host API library and MCU API library
• Microsoft Windows 2000, XP, Vista and WinCE (4.2, 5.0 and 6.0)* are supported
