Application Specific Microcontrollers Part Context

Rochester Electronics specializes in the sourcing and distribution of obsolete and hard-to-find integrated circuits. The MQ82380 series originates from TEMIC Semiconductor, which was later acquired by Infineon Technologies. Rochester Electronics provides these legacy components to support long-term production runs where original manufacturer availability is limited.

Application Specific Microcontrollers Replacement Considerations

Direct pin-for-pin replacements may include other MQ82380 variants with different suffixes indicating packaging or temperature grade variations. Cross-referencing with original TEMIC/Infineon datasheets is required to verify electrical compatibility and firmware compatibility before substitution.
