Choose the right EZ-PD™ PMG1 MCU for your application requirement - KBA232687

Version: **

EZ-PD PMG1 (Power Delivery Microcontroller Gen1) is a family of high-voltage USB-C power delivery (PD) microcontrollers. PMG1 can be employed in any embedded system that provides/consumes power to/from a high-voltage USB-C PD port, and leverages the microcontroller to provide additional control capability.

These chips include an Arm® Cortex® – M0 CPU and USB PD controller along with analog and digital peripherals.

There are three different PMG1 chips offered presently, each with unique features. So, a basic understanding of the important features and key differences between the chips would help you choose the most suitable PD MCU for your application.

The following table presents the notable differences between the chips and will assist you in selecting the appropriate PMG1 MCU. For a detailed look on the differences between the chips, see the datasheets (https://www.cypress.com/products/ez-pd-pmg1).
