Connecting to L4969

L4969 is a combined voltage regulator and low-speed CAN interface from

STMicroelectronics.

The following figure shows how to connect the L4969 CAN interface to the ST10F27x

microcontroller when working on an SPI bus with multiple peripherals.

Note:

For further information on the L4969, please refer to the L4969 datasheet and the available

application notes for this device.

When no other peripherals are connected to the SPI bus, the L4969 can be directly

connected to the ST10 SPI lines without any further constraints.
