New functionalities

2.1

CAN module

The ST10F168 has only one CAN module of the B-CAN type.

The ST10F276 has two CAN modules of the C-CAN type.

The C-CAN cells provide additional Message Objects and new functionalities like Time

Triggered Protocol capability. The main difference is that the Message Objects are no longer

directly accessed as memory but are available through a Message Interface. This changes the

programming model of the modules.

2.1.1

Hardware impact

None.

2.1.2

Software impact

Re-write the CAN Drivers

2.2

Real time clock

This is a new functionality of the ST10F276.

The Real Time Clock is an independent timer. Its clock is directly derived from the clock

oscillator so that it can keep on running even in idle or power down mode (if enabled).

2.2.1

Hardware impact

None

2.2.2

Software impact

None. By default, this peripheral is disabled.

2.3

MAC unit

This Multiply and Accumulate Unit is a feature added on the ST10F276.

2.3.1

Hardware impact

None

2.3.2
