The DP83EC315-Q1 is a 100Mbps, ultra-low latency Remote Control Edge (RCE) device designed for automotive ECU applications, including lighting, door, seat and tailgate. The device supports the control of multiple analog drivers using SPI, I2C, QSPI and UART interfaces. These interfaces feature programmable baud rates and configurable timing parameters to meet diverse analog driver requirements. To enhance functional safety, a hardware-based state machine is integrated to mitigate risks associated with firmware/flash tampering and the safety qualification of operating systems or firmware.
DP83EC315-Q1 Transport protocol is based on IEEE1722-2025 ABB/GBB protocol and aligned with OA TC18 RCP draft v0.5 specifications. DP83EC315-Q1 supports Layer 2 frame header decode and offers ingress filters for DMAC, VLAN and stream-id.
DP83EC315-Q1 can interface with micro LED (uLED) controllers and TI’s DLP controllers at frame rates as high as 120fps along with controlling complete HD Headlamp functions (low beam, high beam, DRL, Tail Indicator, leveling). The RCE supports streaming serial peripherals including High Speed UART (HS-UART) and QSPI to suit different pixel uLEDs from 4K up to 100K pixels.
The DP83EC315-Q1 has inbuilt safe state manager to monitor communication health and perform preconfigured safe state operation in event of communication failure. DP83ED315-Q1 also can download initialization configuration for fast start-up time.
The DP83EC315 has integrated 100Base-T1 PHY and fully interoperable with PHYs and Switches compliant to 100Base-T1 standards. DP83EC315 is also compliant to Open Alliance EMC specification of the 100Base-T1 PHY.
