STMicroelectronics SPC56ELADPT144S

Overview

SPC56ELADPT144S from STMicroelectronics is a mini evaluation module designed for the SPC56ELxx automotive microcontroller family, supporting 144-pin LQFP packages. It interfaces with the SPC56XXMB motherboard to provide full access to CPU I/O signals, dual CAN (HS + LS/FT), dual LIN, SCI, dual FlexRay, user buttons/LEDs, analog potentiometer input, and configurable 3.3 V/5 V logic-level peripherals.

For engineers reviewing the SPC56ELADPT144S datasheet, SPC56ELADPT144S pinout, SPC56ELADPT144S application, or SPC56ELADPT144S equivalent, this module enables rapid validation of automotive powertrain, body control, and chassis communication stacks using real-world CAN/LIN/FlexRay signal routing, voltage-regulated I/O domains, and hardware-configurable transceiver modes.

Technical Context

The SPC56ELADPT144S operates as a daughter card in a modular evaluation system, requiring the SPC56XXMB motherboard for power, debug, and peripheral interface. It routes all 144 pins of the target SPC56ELxx MCU to expansion headers and prototyping areas while enabling hardware-selectable logic levels (3.3 V or 5 V) per peripheral group.

It integrates jumper-configurable dual CAN channels (one HS-only, one HS/LS-FT selectable), two LIN channels (one populated, one footprint-only), one SCI channel with DB9 female connector, and two FlexRay channels (one fully populated, one footprint-only), all synchronized to the host motherboard's clock and power domains.

FAQ

Does the SPC56ELADPT144S include the SPC56ELxx microcontroller?

No. The SPC56ELADPT144S is a carrier board only - the target SPC56ELxx MCU (e.g., SPC56EL60L5) must be purchased separately and mounted on the mini module. It is not pre-populated and requires manual placement or socketing.

What motherboard is required to use this module?

The SPC56ELADPT144S requires the SPC56XXMB motherboard to operate. The motherboard provides 12 V power distribution, JTAG/SWD debugging, USB-to-SCI bridge, and interconnect for all high-speed buses (CAN, LIN, FlexRay). No standalone operation is supported.

How are the CAN and LIN transceivers configured?

CAN Channel 1 uses a fixed high-speed transceiver with DB9 male connector; CAN Channel 2 allows jumper selection between high-speed and low-speed fault-tolerant modes. LIN Channel 1 has a populated transceiver with pin header; LIN Channel 2 has only footprints - no components installed.

Can logic voltage levels be changed for peripherals?

Yes. Jumpers enable selection between 3.3 V and 5 V I/O domains for CAN, LIN, SCI, and FlexRay peripherals - matching target ECU voltage requirements without external level shifters or redesign.
