Hello,
My customer is developing health care products using MSP430F6433.
They are creating FMEA of MSP430F6433.
In the process, I have received the inquiry what happens to a damage and functionality when the pin of a table is open.
Pin | Open the Pin | ||||
No. | Name | Damage | Functionality | Pin Description | Comments |
23 | P2.6/P2MAP6/R03 | General-purpose digital I/O with port interrupt and mappable secondary function, Default mapping: no secondary function, Input/output port of lowest analog LCD voltage (V5) | |||
24 | P2.7/P2MAP7/ LCDREF/R13 |
General-purpose digital I/O with port interrupt and mappable secondary function,Default mapping: no secondary function, External reference voltage input for regulated LCD voltage Input/output port of third most positive analog LCD voltage (V3 or V4) |
|||
27 | VCORE | Regulated core power supply (internal use only, no external current loading) | |||
28 | P5.2/R23 | General-purpose digital I/O Input/output port of second most positive analog LCD voltage (V2) |
|||
76 | VSSU | PU ground supply ( PU.0 and PU.1 are not used. ) | |||
80 | LDOI | LDO input ( LDO is not used. ) | |||
81 | LDOO | LDO output ( LDO is not used. ) | |||
86 | VBAK | Capacitor for backup subsystem. Do not load this pin externally. For capacitor values, see CBAK in Recommended Operating Conditions. (Backup voltage is not supplied.) |
|||
87 | VBAT | Backup or secondary supply voltage. If backup voltage is not supplied, connect to DVCC externally. (Backup voltage is not supplied.) |
Moreover, when between the pins of the next table short-circuits, I have received the inquiry what happens to a damage and functionality similarly.
Pin to Pin Short | ||||||||
No. | Name | Pin Description | No. | Name | Pin Description | Damage | Functionality | Comments |
26 | DVSS1 | Digital ground supply | 27 | VCORE | Regulated core power supply (internal use only, no external current loading) | |||
81 | LDOO | LDO output | 82 | NC | No connect.(high) | |||
85 | P7.3/XT2OUT | General-purpose digital I/O Output terminal of crystal oscillator XT2 (No connect.(high)) |
86 | VBAK | Capacitor for backup subsystem. Do not load this pin externally. For capacitor values, see CBAK in Recommended Operating Conditions. | |||
86 | VBAK | Capacitor for backup subsystem. Do not load this pin externally. For capacitor values, see CBAK in Recommended Operating Conditions. | 87 | VBAT | Backup or secondary supply voltage. If backup voltage is not supplied, connect to DVCC externally. |
Please let me know in the range to understand.
