MCZ33897AEFR2

Drivers, Receivers, Transceivers Overview

The MCZ33897AEFR2 is a Single Wire CAN (SWCAN) transceiver manufactured by NXP USA Inc. It provides the physical layer for digital communications over a single-wire medium using CSMA/CR protocols. The device operates directly from a vehicle's 12 V battery system or broad DC-power sources, supporting data rates of 33.33 kbps and 83.33 kbps. It features a high-voltage wake-up capability to control module regulators and includes a control terminal for sleep mode activation. The component complies with GMW3089v2.4 specifications and is housed in a 14-terminal SOICN package.

Drivers, Receivers, Transceivers Feature Summary

• Provides waveshaping functionality to minimize electromagnetic interference (EMI).
• Detects and automatically handles loss of ground conditions to maintain bus integrity.
• Includes current limit protection to prevent damage resulting from bus shorts.
• Features built-in thermal shutdown on the bus output for enhanced safety.

Drivers, Receivers, Transceivers Applications

• Single Wire Controller Area Network (SWCAN) physical layer implementation.
• Automotive modules requiring low power consumption via regulator control.
• Factory or assembly line communication systems utilizing high-speed modes.
• Applications compliant with General Motors GMW3089v2.4 specifications.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EF indicates Pb-free packaging design as documented in the datasheet. Confirm the device variant matches the required pin configuration and functional differences compared to other series members. Ensure compatibility with the intended operating temperature range and voltage supply requirements before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 14-pin package with a Control (CNTL) terminal is required for regulator management. The 'A' variation offers a maximum load voltage of 0.1 V in sleep mode, differing from the standard 1.0 V limit. Consider the presence of the CNTL pin for applications needing explicit sleep mode signaling to external logic.

Drivers, Receivers, Transceivers Part Context

This part belongs to the 33897 Series, which encompasses multiple variations including 33897, 33897T, 33897C, and 33897D. These variants differ in package size, ESD ratings, and specific electrical characteristics such as quiescent current and load voltage limits. The MCZ prefix typically denotes automotive-grade qualification within this family.

Drivers, Receivers, Transceivers Replacement Considerations

MC33897CTEF is listed as a parameter equivalent substitute for discontinued parts in the series. Verify pinout and functional equivalence against the specific requirements of the original design before substitution.
