Product details
Overview
AEK-CON-C1D9031 from STMicroelectronics is a dedicated connector board bridging the AEK-MCU-C1MLIT1 SPC582B automotive MCU board and AEK-AUD-D903V1 FDA903D Class D audio amplifier board. It integrates an L9616 CAN transceiver, I2S level translator (SN74LVC2T45), 5V-compliant potentiometer interface, and voltage regulation for debug signal conditioning - enabling synchronized audio monitoring and remote CAN-based command control in automotive AVAS systems.
For engineers reviewing the AEK-CON-C1D9031 datasheet, AEK-CON-C1D9031 pinout, AEK-CON-C1D9031 application, or AEK-CON-C1D9031 equivalent, this board serves as a validated interconnect solution for SPC5-based infotainment and Electric Vehicle Warning Sound (AVAS) sub-modules requiring I2S synchronization, CAN command routing, analog slider input, and level-shifted test signal integrity.
Technical Context
The board implements bidirectional level translation between the audio board's 3.3V I2S TEST_IN signal and the MCU's 5V-tolerant GPIO, using SN74LVC2T45 with DIR-controlled directionality. It routes 19-pin and 20-pin female headers for MCU and audio board mating, plus a 15-pin male header (J2) for internal interconnection - all requiring full jumpering except pins 19–20 for I2S test path isolation.
CAN communication is enabled via L9616 transceiver (TXO/RXO pins connected to MCU's CAN3_TX/CAN3_RX), with dedicated 6-pin male header (J4) for CAN-H/CAN-L/GND/+5V. Two 4-pin headers (J5, J6) accept external 5V-slider potentiometer boards, feeding ADC_SPEED and ADC_VOL signals directly to MCU analog inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Connector/interposer board - no active IC functionality; provides signal routing, level translation, and interface standardization |
| I2S Level Translation | SN74LVC2T45 dual-bit translator shifts 3.3V I2S TEST_IN from audio board to 5V-compatible logic level for MCU GPIO capture |

| Analog Input Support | Two 4-pin headers (J5/J6) accept 5V-slider potentiometers; outputs feed MCU ADC channels ADC_SPEED and ADC_VOL |
| Power Regulation | LK112M33TR 3.3V LDO supplies regulated power to level translator and CAN transceiver logic side |
| Header Configuration | 19×2 female (J1) for MCU board; 20×2 female (J3) for audio board; 15×2 male (J2) for internal bridge; jumpers required on all positions except 19–20 |

FAQ
What is the primary function of AEK-CON-C1D9031 in an automotive audio system?
AEK-CON-C1D9031 serves as a physical and electrical interface board that connects the SPC582B MCU board (AEK-MCU-C1MLIT1) and FDA903D Class D amplifier board (AEK-AUD-D903V1). It enables synchronized I2S audio data transfer, CAN-based command routing, analog slider input for volume/speed control, and level translation for debug signals - forming a complete AVAS sub-module foundation.
Which MCU and amplifier boards is AEK-CON-C1D9031 specifically designed to interconnect?
AEK-CON-C1D9031 is engineered exclusively for use between AEK-MCU-C1MLIT1 (SPC582B Chorus family MCU with 1MB Flash) and AEK-AUD-D903V1 (FDA903D automotive Class D digital amplifier). Its pinout, jumper configuration, and signal routing match the native interfaces of these two boards - including I2S, CAN, ADC inputs, and power domains.
How does the board handle level mismatch between the audio board's I2S test signal and the MCU's GPIO?
The board uses an SN74LVC2T45 dual-bit level translator with DIR pin controlled to shift the 3.3V I2S TEST_IN signal from AEK-AUD-D903V1 to a 5V-compatible logic level for reliable sampling by the SPC582B's GPIO. This ensures timing-aligned capture of the debug signal without signal degradation or voltage overstress.
Can AEK-CON-C1D9031 be used outside the AutoDevKit™ ecosystem?
No - AEK-CON-C1D9031 is not a general-purpose breakout or adapter. Its mechanical layout, pin mapping, jumper requirements, and signal routing are tightly coupled to AEK-MCU-C1MLIT1 and AEK-AUD-D903V1. It lacks standalone power management, firmware, or configuration logic and requires both host boards to operate as intended in AVAS or infotainment reference designs.
