Frequently asked questions
The 8×10b SAR and 7×24b Sigma Delta share the 62 I/O — are there dedicated fixed analog pins?
No fixed block. Both converter banks map to the 62-I/O GPIO pool through port-mux registers at firmware init. Pin allocation is a register configuration decision, not a hardware hard-wired assignment — the firmware team needs to plan channel-to-pin mapping before PCB routing is locked.
Does the MSP430F6778AIPZR have a hardware CRC engine for Class B safety firmware?
The CPUXV2 core in the MSP430F6xxx family includes an on-die CRC module that can cover Flash memory ranges — useful for UL/IEC 60730 Class B boot and vector table integrity checks. Confirm the exact CRC polynomial and address-range coverage against the device-specific errata and family reference manual, as coverage scope can vary by silicon stepping.
Does the MSP430F6778AIPZR support LINbus and is it a drop-in replacement for the MSP430F67771?
LINbus is confirmed on-die, operating up to the 20 kBd LinSpec rate. Regarding pin compatibility with the earlier MSP430F67771AIPZR: both share the 100-LQFP (14×14 mm) package, but pinout compatibility is a per-signal mapping question that requires referencing the two device datasheets side-by-side — the LCD segment routing and UART pin assignment in particular can differ between F67771 and F6778 stepping. A PCB spin cannot be ruled out without that pinout comparison; do not assume drop-in compatibility without confirmation.
