SIT2515T-I/SO

The SIT2515 is a standalone Controller Area Network (CAN) controller with an SPI interface, implementing the CAN Specification, Version 2.0B. This device is primarily used in automotive and industrial applications for data reception and transmission. It is capable of transmitting and receiving standard frames, extended frames, and remote frames. The SIT2515 features 2 receive masks and 6 receive filter registers for filtering out unwanted messages, thereby reducing the load on the host MCU. The SIT2515 communicates with the MCU via the industry-standard SPI interface.

Key features

• Pin-to-pin and functionally compatible with MCP2515
• Supports CAN2.0B at 1.0Mb/s, data field length 0–8 bytes, standard frames, extended frames, and remote frames
• Receive buffers, masks, and filters: two receive buffers with storage priority, 6 × 29-bit acceptance filters, 2 × 29-bit acceptance masks
• Message filtering using the first two data bytes
• Three transmit buffers with configurable transmit priority and abort transmission
• High-speed SPI interface (10MHz), SPI modes 0,0 and 1,1
• One-shot transmission mode ensures each message is sent only once
• Programmable clock prescaler pin
• Start-of-Frame (SOF) pin for SOF signal detection
• Interrupt output pin with interrupt enable control
• Buffer-full output pins configurable as RX buffer full interrupt or general-purpose input pins
• RoHS-compliant lead-free package
• Dedicated Request-to-Send (RTS) pins configurable as TX buffer RTS signals or general-purpose input pins
• Low-power CMOS process, 2.7–5.5V supply, 5mA active current (typical), 1μA standby current (typical)
• Industrial temperature range: -40°C to 85°C
