Part Review Report

Thought for 4 sec

I’ll review the part metadata, find and set the official datasheet URL if needed, then compare symbol/footprint/pin details against the datasheet and summarize any issues.

The pinout and footprint geometry match the datasheet; I found only metadata-level issues so far. I’m creating a short review file with the full comparison and recommendations.

Completed the RV-8803-C7 part review and created the detailed report: RV-8803-C7 Part Information Review.

Open items:

Datasheet URL was already populated, so I did not replace it; I noted the official Micro Crystal URL in the report.
No pinout or footprint mismatches found.
Metadata refinements flagged: missing Part Type, underspecified package, unspecified terminal pin types, and lid-to-VSS note.

Suggested next steps:

Update Part Type and package metadata.
Add terminal pin electrical types for better ERC.
Optionally replace the uploaded datasheet URL with the official Micro Crystal PDF URL.

RV-8803-C7 Part Information Review

Date: 2026-07-14

Scope

Reviewed the published Flux part project for Micro Crystal AG RV-8803-C7 against the available part metadata, schematic symbol terminals, footprint payload, and datasheet content.

Official manufacturer datasheet also found at: https://www.microcrystal.com/fileadmin/Media/Products/RTC/Datasheet/RV-8803-C7.pdf

The Datasheet URL property was already populated, so it was not changed under the requested condition. If the project should prefer manufacturer-hosted links, replace the current uploaded-copy URL with the official Micro Crystal URL above.

Datasheet key specifications

Table

Parameter	Datasheet value
Function	SMT real-time clock module with integrated CMOS RTC IC and 32.768 kHz crystal
Interface	I2C-bus, Fast Mode up to 400 kHz
I2C address	7-bit 0x32; write 0x64, read 0x65
Supply voltage	1.5 V to 5.5 V for timekeeping and 100 kHz I2C; 2.0 V to 5.5 V for 400 kHz I2C
Timekeeping current	240 nA typ at 3 V, I2C inactive, CLKOUT disabled; datasheet extraction also reports max values up to 600 nA at 1.5/3 V and 700 nA at 5 V
Accuracy	+/-3 ppm from -40°C to +85°C; +/-7 ppm from +85°C to +105°C with limitations

Symbol pin cross-check

Table

Pin	Flux terminal	Datasheet terminal	Datasheet description	Result
1	SDA	SDA	Serial Data	Match
2	CLKOUT	CLKOUT	Clock Output	Match
3	VDD	VDD	Power Supply Voltage	Match
4	CLKOE	CLKOE	Clock Output Enable	Match
5	VSS	VSS	Ground	Match
6	~INT	INT	Interrupt Output	Functional match; naming differs by active-low marker
7	EVI	EVI	Event Input	Match
8	SCL	SCL	Serial Clock Input	Match

Notes:

Pin numbers and terminal names are aligned with the datasheet top-view pin table.
Flux uses ~INT while the datasheet labels the pin INT. This is acceptable if the symbol convention intentionally marks active-low interrupt behavior, but it is not the exact datasheet label.
Terminal Pin Type properties are all currently Unspecified; these could be improved for ERC quality.

Suggested pin type refinements:

SDA: Bi-Directional / I2C data
CLKOUT: Output
VDD: Power In
CLKOE: Input
VSS: Ground
INT / ~INT: Output or Open Collector/Open Drain if confirmed from the detailed datasheet/application manual
EVI: Input
SCL: Input

Footprint cross-check

Flux footprint payload summary:

Footprint name/description: RV8803C7, SON-8.
Body fab outline: 3.2 mm x 1.5 mm.
Pads: 8 SMD rectangular pads.
Pad size: 0.5 mm x 0.8 mm.
Horizontal pitch: 0.9 mm.
Row center spacing: 1.2 mm, which gives 0.4 mm edge-to-edge gap with 0.8 mm pad height.
Pad numbering top-view pattern: top row 1-2-3-4, bottom row 8-7-6-5.
Pin-1 silk marker near the top-left pad.

Datasheet comparison:

Recommended pad size 0.5 mm x 0.8 mm: match.
Horizontal pitch 0.9 mm: match.
Vertical pad gap 0.4 mm: match.
Package body 3.2 mm x 1.5 mm: match.
Top-view pad numbering/orientation: match.

No footprint geometry or pad numbering mismatch found.

Review check results

Flux Component Review Checks reported one warning:

Project: Part Type is not set.

Mismatches / issues flagged

Table

Severity	Area	Finding	Recommendation
Warning	Metadata	Part Type is not set.	Set Part Type to Integrated Circuit, RTC, or a platform-supported RTC/clock category if available.
Warning	Metadata	Package or Case Code is only `Module`, while the datasheet calls out C7 / SON-8, 3.2 x 1.5 x 0.8 mm.	Refine package metadata to `C7 / SON-8, 3.2 x 1.5 x 0.8 mm` if supported.
Info	Datasheet URL	Existing property points to an uploaded PDF copy; official manufacturer URL was found.	Prefer the official Micro Crystal PDF URL for long-term traceability if Flux allows replacing the current value.
Info	Symbol naming	Pin 6 is named `~INT`; datasheet label is `INT`.	Keep if intentional to show active-low behavior; otherwise rename to exact datasheet label and document polarity separately.
Info	Symbol metadata	All terminal Pin Type properties are `Unspecified`.	Add pin electrical types to improve ERC and part quality.
Info	Package note	Datasheet states metal lid is connected to VSS pin 5, but no visible metadata note was found.	Add a role/details note or package note: `Metal lid connected to VSS / pin 5`.

Conclusion

The RV-8803-C7 part is substantially correct. The schematic pin numbering, terminal mapping, footprint pad count, pad size, pitch, body outline, and pin-1 orientation all match the datasheet. The remaining issues are metadata completeness/refinement items rather than functional symbol or footprint errors.
