1 Feature set dependent on selected peripheral multiplexing; table shows example.

2 Based on 125 C ambient operating temperature and subject to full device characterisation.

3 The e200z0h can run at speeds up to 80 MHz. However, if system frequency is >80 MHz (e.g., e200z4d running at 120 MHz) the e200z0h needs

to run at 1/2 system frequency. There is a configurable e200z0 system clock divider for this purpose.

4 DMAMUX also included that allows for software selection of 32 out of a possible 57 sources.

5 Not shared with 12-bit ADC, but possibly shared with other alternate functions.

6 There are 23 dedicated ANS plus 4 dedicated ANX channels on LQPF176. For higher pin count packages, there are 29 dedicated ANS plus 4

dedicated ANX channels.

7 16x precision channels (ANP) and 3x standard (ANS).

8 Not shared with 10-bit ADC, but possibly shared with other alternate functions.

9 As a minimum, all timer channels can function as PWM or Input Capture and Output Control. Refer to the eMIOS section of the device reference

manual for information on the channel configuration and functions.

10 CAN Sampler also included that allows ID of CAN message to be captured when in low power mode.

11 STCU controls MBIST activation and reporting.

12 Estimated I/O count for proposed packages based on multiplexing with peripherals.
