Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSR1024A05-ILLP-R is determined by the following critical parameters:

• RF Family/Standard: Bluetooth v4.2 protocol support
• Type: Integrated TxRx + MCU architecture
• Serial Interfaces: Minimum support for I2C, SPI, UART
• Supply Voltage: Operating range compatibility
• Package: Physical form factor and pin count
• Compliance: RoHS3 and REACH status

The CC1350F128RGZT from Texas Instruments qualifies as a substitute based on matching RF standard (Bluetooth v4.2), integrated transceiver-MCU architecture, overlapping serial interface support, and equivalent compliance certifications. Differences in package form factor (48-VFQFN vs. 36-WFLGA), memory configuration, and electrical characteristics require design-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The CC1350F128RGZT is suitable as a substitute for the CSR1024A05-ILLP-R based on the following factors:

• Both components maintain Bluetooth v4.2 protocol compliance and integrated TxRx + MCU architecture
• Both achieve ROHS3 compliance and REACH Unaffected status
• The CC1350F128RGZT carries Active product status, ensuring long-term availability and support
• The CSR1024A05-ILLP-R is designated Not For New Designs, making transition to an active alternative necessary for new development

Design considerations include package form factor change (36-pin to 48-pin), reduced flash memory (128kB vs. 256kB), and modified GPIO count (30 vs. 15). The CC1350F128RGZT provides superior RF performance (9dBm output, -124dBm sensitivity) and wider supply voltage range (1.8V ~ 3.8V).

Frequently Asked Questions (FAQ)

Q: Can the CC1350F128RGZT directly replace the CSR1024A05-ILLP-R without PCB redesign?

A: No. The package form factor differs (48-VFQFN vs. 36-WFLGA), requiring PCB layout modification. Pin assignments and GPIO count also differ, necessitating firmware and schematic updates.

Q: Are the serial interfaces compatible between these parts?

A: Both support I2C, SPI, and UART. The CSR1024A05-ILLP-R includes I2S and PCM; the CC1350F128RGZT includes I2S but not PCM. Applications requiring PCM must implement alternative solutions.

Q: What are the memory implications of substitution?

A: The CC1350F128RGZT provides 128kB Flash and 28kB SRAM versus the CSR1024A05-ILLP-R's 256kB Flash and 80kB RAM. Applications exceeding these limits require code optimization or alternative component selection.

Q: Does the CC1350F128RGZT support the same operating temperature range?

A: The CC1350F128RGZT extends the lower temperature limit to -40°C compared to the CSR1024A05-ILLP-R's -30°C, providing broader environmental compatibility.

Q: Are compliance certifications equivalent?

A: Both components are ROHS3 Compliant and REACH Unaffected, maintaining equivalent regulatory compliance for EU and international markets.
