Rochester Electronics Controllers QE82527-G

The QE82527-G is a serial communications controller that supports the CAN Specification 2.0, accommodating both standard and extended data and remote frames. It features a programmable global mask for message identifiers and supports 15 message objects with an 8-byte data length, including 14 transmit/receive buffers and one receive buffer with a programmable mask. This controller offers a flexible CPU interface, supporting 8-bit and 16-bit multiplexed modes, as well as 8-bit non-multiplexed synchronous and asynchronous modes, along with a serial interface. It includes a programmable bit rate and clock output, a flexible interrupt structure, and a configurable output driver and input comparator. Additionally, it provides two 8-bit bidirectional I/O ports and comes in a 44-lead PLCC package, maintaining pinout compatibility with the 82526 model. Engineers should note that the specifications are subject to change, and it is advisable to verify the latest datasheet before finalizing any design.
