ATBTLC1000A-MU-T Equivalent & Substitute Parts

Part Overview

The ATBTLC1000A-MU-T is an integrated RF transceiver with embedded microcontroller unit (MCU) designed for Bluetooth v4.1 applications operating in the 2.4GHz ISM band. This device combines both RF transmission/reception and MCU functionality in a single 32-VFQFN package, enabling compact Bluetooth Low Energy (BLE) implementations.

The ATBTLC1000A-MU-T is classified as Obsolete. Locating equivalent or substitute components is necessary for ongoing production support, design refreshes, or when inventory becomes unavailable. Substitute parts must maintain functional compatibility within the constraints of the application's RF protocol, frequency band, power budget, and physical form factor requirements.

Key Parameters

Substitute Part Grouping Explanation

The ATBTLC1000A-MU-T integrates both RF transceiver and MCU functionality in a single package. Substitution analysis must account for the following critical parameters:

RF Protocol & Frequency Band: The main part operates exclusively on Bluetooth v4.1 at 2.4GHz. The substitute part SX1231HIMLTRT is a general ISM transceiver operating in sub-1GHz frequency bands (290MHz–340MHz, 424MHz–510MHz, 862MHz–1.02GHz) without integrated MCU.

Device Architecture: The ATBTLC1000A-MU-T combines TxRx + MCU in a single IC. The SX1231HIMLTRT is a TxRx-only device, requiring an external MCU for system implementation.

Frequency Incompatibility: The SX1231HIMLTRT does not support the 2.4GHz Bluetooth band. This represents a fundamental protocol and frequency mismatch that prevents direct substitution in Bluetooth-specific applications.

Package Differences: The ATBTLC1000A-MU-T uses a 32-VFQFN package; the SX1231HIMLTRT uses a 24-VQFN package, requiring PCB layout redesign.

Compliance & Certifications: Both parts maintain ROHS3 compliance and REACH Unaffected status, supporting regulatory continuity.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Not Feasible: The SX1231HIMLTRT cannot serve as a direct substitute for the ATBTLC1000A-MU-T in Bluetooth v4.1 applications. The frequency band incompatibility (sub-1GHz vs. 2.4GHz) and absence of integrated MCU functionality create fundamental architectural differences.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and hazardous substance regulations. However, compliance alignment does not resolve protocol or frequency incompatibilities.

Product Status Consideration: The ATBTLC1000A-MU-T is Obsolete; the SX1231HIMLTRT is Active. For applications requiring Bluetooth v4.1 functionality, alternative Bluetooth-capable transceivers from active product lines should be evaluated rather than attempting substitution with incompatible ISM-band devices.

Frequently Asked Questions (FAQ)

Q: Can the SX1231HIMLTRT replace the ATBTLC1000A-MU-T in a Bluetooth application?

A: No. The SX1231HIMLTRT operates in sub-1GHz ISM bands and does not support Bluetooth v4.1 or the 2.4GHz frequency band required by the ATBTLC1000A-MU-T. Protocol and frequency incompatibility prevent substitution.

Q: What is the primary functional difference between these parts?

A: The ATBTLC1000A-MU-T integrates both RF transceiver and MCU in a single package for Bluetooth applications. The SX1231HIMLTRT is a transceiver-only device for general ISM applications, requiring an external MCU and operating at different frequencies.

Q: Are there package compatibility considerations?

A: Yes. The ATBTLC1000A-MU-T uses a 32-VFQFN package; the SX1231HIMLTRT uses a 24-VQFN package. Different pin counts and footprints require PCB redesign and cannot be used interchangeably on existing layouts.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH Unaffected. However, regulatory alignment does not address the fundamental protocol and frequency incompatibilities that prevent substitution.

Q: What should be done if the ATBTLC1000A-MU-T is no longer available?

A: For Bluetooth v4.1 applications, identify alternative Bluetooth-capable transceivers from active product lines that support the 2.4GHz band and required protocol specifications. Substitution with sub-1GHz ISM devices is not viable.
