Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'IZQWR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Check for obsolescence status, as this part number may be discontinued or superseded by newer revisions in the MSP430BT family. Ensure compatibility with required operating temperature ranges (-40°C to +85°C).

Application Specific Microcontrollers Selection Notes

Select this component when both 16-bit processing performance and integrated Bluetooth functionality are required in a compact form factor. Compare against standard MSP430F series if wireless capability is not needed, as those variants may offer different peripheral sets or lower costs. Verify that the 113-pin BGA footprint fits the PCB design constraints.

Application Specific Microcontrollers Part Context

This part belongs to the MSP430BT family, which combines the ultralow-power MSP430 MCU with a Bluetooth radio. It is distinct from the MSP430F series, which lacks the integrated wireless transceiver. The 'IZQWR' suffix indicates the specific package variant and packaging method.

Application Specific Microcontrollers Replacement Considerations

Check for direct replacements within the MSP430BT family, such as MSP430BT5190IPZR (LQFP-100 package), if pinout compatibility is required. Verify functional equivalence regarding flash size, RAM, and Bluetooth profile support before substituting.
