The CP2103 is a highly-integrated?USB-to-UART Bridge Controller?providing a simple solution for updating RS-232/RS-485 designs to USB using a minimum of components and PCB space. The CP2103 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5x5 mm QFN-28 package (sometimes called ?MLF? or ?MLP?). No other external USB components are required.

The device reduces external components by integrating the USB termination resistors. The?MCP2200?also has 256 bytes of integrated user EEPROM.The?MCP2200?has eight general purpose input/output pins. Four pins have alternate functions to indicate USB and communication status.

The?MCP2551?is a high-speed?Controller Area Network?(CAN), fault-tolerant?device that serves as the interface between a?CAN?protocol controller?and the physical bus. The MCP2551?device provides differential transmit and receive?capability for the CAN protocol controller, and is fully?compatible with the ISO-11898 standard, including 24V?requirements. It will operate at speeds of up to 1 Mb/s.

Typically, each node in a CAN system must have a?device to convert the digital signals generated by a?CAN controller to signals suitable for transmission over?the bus cabling (differential output). It also provides a?buffer between the CAN controller and the high-voltage?spikes that can be generated on the CAN bus by?outside sources (EMI, ESD, electrical transients, etc.).

The MT8870D/MT8870D-1 is a complete DTMF receiver integrating both the band split filter and digital decoder functions. The filter section uses switched capacitor techniques for high and low group filters; the decoder uses digital counting techniques to detect and decode all 16 DTMF tone pairs into a 4-bit code. External component count is minimized by on chip provision of a differential input amplifier, clock oscillator and latched three-state bus interface.
