HDMI interface in 64TFBGA — what the package and status mean for your BOM
The TDA19989BET/C1551 is an HDMI interface IC from NXP Semiconductors, supplied in a 64-ball TFBGA package. The TFBGA (Thin Fine-Pitch Ball Grid Array) footprint demands a controlled-impedance PCB stack-up with microvia fan-out — the 0.50 mm ball pitch typically requires a 4-layer board to escape the inner rows. The part is designated for the Memory (DRAM / SRAM / Flash / EEPROM) category, indicating it likely serves as a bridge between an HDMI source and a memory-backed display buffer or frame grabber. Production status is Active per the manufacturer's lifecycle record. This means the TDA19989BET/C1551 remains in NXP's current portfolio — no end-of-life notice, no last-time-buy window. For a BOM line that already carries this order code, the supply channel is stable through authorized and independent distribution; new designs can commit to it without a migration timeline.
Sourcing posture — Active part, quoted to order
The TDA19989BET/C1551 is sourced through independent distribution channels. Availability and current pricing are confirmed at RFQ against the specific BOM quantity. No stock-holding claim is made; each order is quoted individually. The Bulk packaging format (tray or tube, not tape-and-reel) is typical for engineering samples or low-volume production runs — factor this into your pick-and-place setup if the line expects reel-fed parts.
