Microchip Technology’s MCP2515 is a stand-alone Controller Area Network (CAN) controller that implements the CAN specification, version 2.0B. It is capable of transmitting and receiving both standard and extended data and remote frames. The MCP2515 has two acceptance masks and six acceptance filters that are used to filter out unwanted messages, thereby reducing the host MCU’s overhead. The MCP2515 interfaces with microcontrollers (MCUs) via an industry standard Serial Peripheral Interface (SPI).
Implements CAN V2.0B - Programmable bit rate up to 1 Mb/s - One programmable mask - Two programmable filters - Three auto-transmit buffers - Two message reception buffers - Does not require synchronization or configuration messages
Hardware Features - Non-volatile memory for user configuration - User configuration automatically loaded on power-up - Eight general-purpose I/O lines individually selectable as inputs or outputs - Individually selectable transmit-on-pinchange for each input - Four 10-bit, analog input channels with programmable conversion clock and VREF sources (MCP2505X devices only) - Message scheduling capability - Two 10-bit PWM outputs with independently programmable frequencies - Device configuration can be modified via CAN bus messages - In-Circuit Serial Programming™ (ICSP™) of default configuration memory - Optional 1-wire CAN bus operation
