PZ254V-11-05P

hand-fit SWD header — XFCN — C492404 — board-l J3; swd-adapter J2 — rec-c492404

Everything below is projected from this project's stored component evidence. Values keep the exact wording, conditions, units and verdicts they were recorded with — nothing here is re-typed, corrected, or combined into an overall judgement about the part.

This record in the catalog: PZ254V-11-05P

Subordinate record

This is a subordinate record. It is a component in its own right, with its own orderable identity and its own placements, but its evidence is audited as part of rec-c529334, because its behaviour is only meaningful in that part's circuit. Read the parent record for the shared context; the facts below are the ones specific to this line.

Coverage

Coverage is stated one domain at a time and is never rolled up. A domain marked open is a question that has not been answered; it is not a finding that the part is unsuitable. A record with no open domains has not thereby been declared safe.

Facts in this domain:

Blocked by: no blocking fact is recorded. What is missing has not been reduced to a specific recorded fact, so the reason above is the whole of what is known.

Facts

Each fact keeps its value, its unit, the conditions it holds under, where it came from and how far it has been confirmed as separate fields, because they are separate claims. A value without its conditions is not the same fact, and a verdict is about the evidence for the value, not about the part.

GUARANTEED_ELECTRICAL

A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.

PROJECT_STATE

A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.

Pin maps

The mapping between schematic pins and PCB pads, or physical terminals for an external part, as recorded. A record may carry more than one map when the same part is documented in more than one context.

Interactions

Behaviour that is not a property of this part alone. Each interaction names the records it spans, the conditions it holds under, and how far it has been confirmed. An interaction that spans several parts appears on every one of their pages, under the same identifier, because it is equally a fact about each.

int-c492404-programming

  • Records involved: rec-c529334, rec-c492404 (this record), rec-c4749199

  • Conditions: Board L J3 and adapter J1/J2 are DNP; use a straight pin-for-pin 1x5 cable, power the target, align both pin-1 marks and the 20-pin shroud key, keep J1.19 isolated, and verify fitment, continuity, target sense and debugger behavior before use

  • Verdict: NEEDS BENCH

Facts this rests on:

Cross-component rules

Rules that span several parts at once and are published in full on the integration page. Each rule's verdict below is that rule's own — it is a statement about the cross-component question, not about this part — and the exact wording of what the rule refuses to conclude is published with the rule itself.

No cross-component rule names this record.

Legend

What the recorded terms on this page mean, in ordinary words. The exact terms above are the ones that count; these descriptions explain them and never replace them.

Verdict

Recorded termWhat it means
NOT APPLICABLEThe parameter does not apply to this part as it is used here.
PASS - primary-source confirmedConfirmed against the manufacturer's own document for this exact part.

Provenance

Recorded termWhat it means
PRIMARY-SPECTaken from the manufacturer's own specification document.
PROJECT-CHOICEA decision made by this project. No vendor asserts it.

Fact class

Recorded termWhat it means
GUARANTEED_ELECTRICALA parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.
PROJECT_STATEA value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.

Coverage status

Recorded termWhat it means
COVEREDEvery question this domain asks is answered by the facts listed against it.
OPENUnresolved. Open means the question has not been answered, not that the part is unsafe — the reason states what is missing.

Source availability

Recorded termWhat it means
AVAILABLEThe document was retrieved and is on record.
SOURCE UNAVAILABLEThe document could not be retrieved. It stays listed so the gap is visible; anything resting on it remains unsourced.

Source authority

Recorded termWhat it means
MANUFACTURER_PRIMARYThe manufacturer's own document for this exact part.
PROJECT_GENERATORA document this project generated, such as a schematic or netlist export.

Identity state

Recorded termWhat it means
UNRESOLVEDThe exact orderable part is not yet confirmed. Substituting a same-name part from another vendor is not permitted on that basis.

Source state

Recorded termWhat it means
SOURCE UNAVAILABLENo document backing this line could be retrieved.

Unit

Recorded termWhat it means
NONEThe value is not a physical quantity, so it carries no unit. Recorded as `NONE`.
