ST公司的SPC584Cx和SPC58ECx系列产品是用于汽车电子的32位Power Architecture MCU,采用两个处理器核e200z420和一个处理器和e200z0,工作频率高达180MHz,满足规范AEC-Q100,具有可变长度编码(VLE),集成了4224 KB (4096 KB代码闪存+128 KB 数据闪存)闪存,以及384 KB通用SRAM,主要用在汽车电子.本文介绍了SPC584Cx和SPC58ECx主要特性,以及评估板AEKD-USBTYPEC1(AEK-USB-2TYPEC1和SPC58EC-DISP)主要特性,框图,电路图和材料清单.

The SPC584Cx and SPC58ECx microcontroller are the first in a new family of devices superseding the SPC564Cx and SPC56ECx family. SPC584Cx and SPC58ECx build on the legacy of the SPC564Cx and SPC56ECx, while introducing new features coupled with higher throughput to provide substantial reduction of cost per feature and significant power and performance improvement (MIPS per mW). On the SPC584Cx and SPC58ECx devices, there are two processor cores e200z420 and one e200z0 core embedded in the Hardware Security Module.

评估板AEKD-USBTYPEC1

USB Type-C™ and USB Power Delivery evaluation kit based on the automotive grade SPC58 MCU and AutoDevKit development initiative

The AEKD-USBTYPEC1 evaluation kit is designed to let you test the USB PowerDelivery protocol stack implemented on the ASIL-B automotive grade 32-bit PowerArchitecture® microcontroller SPC58 C (Chorus) line (from 1 to 10 MB flash, single ormulti-core, including ISO CAN FD and Ethernet peripherals).

The USB Type-C and USB Power Delivery specifications allow smarter connectivity with fewer cables, lessconnectors and universal chargers. The Type-C connector supports all the features of previous standards, andports can be configured to only supply power in a Provider role, only sink power in a Consumer role, or be able to switch between both in a Dual role.

Both data and power roles can be independently and dynamically swapped using the USB Power Deliveryprotocol.

Most automotive applications require support for the Provider role only. When a USB device is connected, theProvider and the device (Consumer) negotiate a contract for the power objects through configuration channels.

The message exchange between Provider and Consumer are listed below:
1. The Provider sends a Source Capabilities message to the Consumer, advertising its powercapabilities.
2. The device then sends a Request for one of the advertised power profiles.
3. The provider accepts or rejects this request according to its power balance
4. If confirmed, provider sends as an Accept message to the device
5. The provider then switches to the requested power profile and sends a PS_Readyconfirmation message

Each received message is acknowledged with a GoodCRCto confirm correct reception. Incorrect receptions areignored and persistent communication errors should trigger a soft reset to re-establish communication. If the errorpersists,a hard reset is performed.
