1.1 Introduction

The original AM263x Control Card (TMDSCNCD263) was developed to enable easy and rapid prototyping of the AM263x and all of the peripherals. The changes between the original Control Card and this specific version, TMDSCNCD263-PMIC, is showcased in Table 2-1.

Table 1-1 Control Card Differences
Subsystem TMDSCNCD263 TMDSCNCD263-PMIC TMDSCNCD263-PMIC Part Number
Power Discrete power Power Management Integrated Chip (PMIC) O3850QDCARQ1
Voltage Supervisor N/A 1x Automotive, multichannel window supervisor with very-high accuracy for 1.2 V and 3.3 V supply rails TPS37042A3OFDDFRQ1
Ethernet 3x Industrial Ethernet PHYs with RJ45 connectors 1x Industrial Ethernet PHY with RJ45 Connector DP83826ERHBT
2x Automotive Ethernet PHY with MATEnet connectors DP83TG720SWRHARQ1

This EVM supports integrated power and safety monitoring that is consistent with ISO26262 ASIL-D by using a PMIC designed for safety-relevant applications as well as an independent, automotive-grade voltage supervisor.

The Control Card described in this user guide has an E1 and E2 revision. The E1 revision of the Control Card requires Hardware modifications for proper use. The E1 design Hardware Modifications are described in Section 5.2. The E2 Design files serve as a reference for the proper implementation of the PMIC with the AM263x. Design files for both E1 and E2 versions of the TMDSCNCD263-PMIC can be found in Section 4.
