Substitute Part Grouping Explanation

The FS32V234CON2VUBR qualifies as a manufacturer-recommended substitute based on the following alignment criteria:

Matching Parameters:

• Identical series designation (FS32V23)
• Identical clock speed (1GHz)
• Identical package type and pinout (621-FCPBGA 17x17)
• Identical I/O voltage levels (1V, 1.8V, 3.3V)
• Identical additional interfaces (I2C, SPI, PCI, UART)
• Identical RAM controller support (DDR3, DDR3L, LPDDR2)
• Identical security features (AES, ARM TZ, Boot, CSE, OCOTP_CTRL, System JTAG)
• Identical mounting type (Surface Mount)
• Identical RoHS and REACH compliance status

Architectural Differences: The substitute part consolidates processor architecture to ARM Cortex-A53 only (4 Core, 32/64-Bit), removing the dedicated ARM Cortex-M4 core present in the original part. Graphics acceleration is not supported in the substitute variant. These differences represent functional reduction rather than incompatibility, as the primary A53 core maintains instruction set compatibility and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FS32V234CON2VUBR is the manufacturer-recommended substitute for the obsolete FS32V234CON1VUB. Selection of the substitute part is appropriate when:

• The application does not require dedicated ARM Cortex-M4 real-time processing capabilities
• Graphics acceleration hardware is not a functional requirement
• The extended operating temperature range of the substitute (-40°C ~ 125°C TJ) meets or exceeds application thermal specifications
• Pin-compatible PCB layouts and firmware targeting the FS32V23 series are already established

The substitute maintains identical package geometry, pinout, I/O voltage specifications, and interface controller feature sets. Both parts comply with REACH regulations and maintain equivalent security feature implementations. The substitute part is currently in active production status, ensuring supply chain availability for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Are the FS32V234CON1VUB and FS32V234CON2VUBR pin-compatible?

A: Yes. Both parts use the identical 621-FCPBGA (17x17) package with matching pinout. PCB layouts designed for the original part are compatible with the substitute without modification.

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

A: The original part includes a dedicated ARM Cortex-M4 core and graphics acceleration hardware. The substitute consolidates to ARM Cortex-A53 architecture only, with the Cortex-M4 functionality repositioned as a co-processor option. Applications not requiring dedicated real-time M4 processing or graphics acceleration will function identically.

Q: Does the substitute part support the same interfaces and controllers?

A: Yes. Both parts provide identical display and interface controller implementations (APEX2-CL, DCU, ISP, LCD, MIPICSI2, Video, VIU) and identical additional interfaces (I2C, SPI, PCI, UART). RAM controller support (DDR3, DDR3L, LPDDR2) is identical.

Q: What is the temperature operating range difference?

A: The original part operates from -40°C to 105°C (TA). The substitute operates from -40°C to 125°C (TJ), providing an extended upper temperature specification. Applications within the original range are fully supported by the substitute.

Q: Are security features equivalent between the two parts?

A: Yes. Both parts implement identical security features: AES, ARM TrustZone, Boot security, CSE, OCOTP_CTRL, and System JTAG capabilities.

Q: Why is the original part classified as Obsolete?

A: The FS32V234CON1VUB has reached end-of-life status. NXP USA Inc. recommends the FS32V234CON2VUBR as the active production alternative for new designs and ongoing supply requirements.
