IEEE 1588 auxiliary clock functions typically require ±50 ppm or tighter. An external crystal or TCXO is required for any precision timing application."},{"question":"Can I run I²C, SPI, and all 8 ADC channels simultaneously on this MCU?","answer":"The 12 GPIO pins are shared between the 8 ADC channels and the communication peripherals. You cannot route all 8 ADC channels independently while I²C and SPI are simultaneously active on their dedicated pins — the shared pins are consumed by the communication function, and firmware must sequence acquisition between communication windows. The pin-mux table in the TI datasheet defines the exact constraints."},{"question":"What is the realistic FRAM budget for a Modbus-RTU stack on this part?","answer":"3.75KB is very tight. A Modbus-RTU master stack with protocol state machine, CRC table, register map, and UART driver typically exceeds 4KB of compiled flash in MSP430 GCC — already over the available space on this device without hand-optimisation or a slave-only implementation. Plan for a stripped-down stack or move to a larger FR2xxx variant if Modbus master functionality is required alongside other peripherals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2111IPW16R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR2111IPW16R when reusing this data.
