Microchip Technology

The MCP23017/MCP23S17 (MCP23X17) device family provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface. • MCP23017 – I2C interface • MCP23S17 – SPI interface The MCP23X17 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B). The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.

The MCP23X18 device provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface. • MCP23018 - I2C interface • MCP23S18 - SPI interface The MCP23X18 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits. The data for each input or output is kept in the corresponding input or output register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.

The MCP2502X/5X devices operate as I/O expanders for a Controller Area Network (CAN) system, supporting CAN V2.0B active, with bus rates up to 1 Mb/s. Contains up to 8 digital I/O and up to 2 PWM ouputs configurable by the user. The MCP2502X/5X allows a simple CAN node to be implemented without the need for a microcontroller.

CAN Input/Output Expander. Contains up to 8 digital I/O, up to 2 PWM outputs, and a one-wire line driver option configurable by the user.

Mixed-Signal Input/Output Expander. Contains up to 8 digital I/O, up to 4 10-bit A/D converters and up to 2 PWM outputs configurable by user.

Mixed Signal Input/Output Expander. Contains up to 8 digital I/O, up to 4 10-bit A/D converters, up to 2 PWM outputs and a one-wire line driver option configurable by the user.

The MCP2510 18-pin stand-alone CAN (Control Area Network) controller features an industry standard SPI serial interface, enabling an easy connection to virtually any microcontroller. The MCP2510 provides immediate CAN support across the entire breadth of Microchip’s 100+ PICmicro® microcontrollers, providing a seamless migration path and maximum design flexibility for CAN designs. The MCP2510 contains on-board features, such as interrupt capability, message masking and filtering, message prioritization, multi-purpose I/O pins, and multiple transmit/receive buffers which significantly offload the microcontroller overhead required to handle CAN message traffic. Applications for the MCP2510 include motor control, smoke detectors, CO detectors, sensors, meters, automotive electronics, climate control and instrument clusters.

The MCP2515 is a second generation stand-alone CAN controller. It is pin and function compatible with the MCP2510 and also includes upgraded features like faster throughput, databyte filtering, and support for time-triggered protocols.
