Not a TZ2812/TZ1815: the H1010 sheet gives no IC name, only “built-in IC”, “SID data protocol” and a different electrical table (VDD 2.5-5.5 V in the IC table, 5 mA constant current, 10 V output rating, 1 kHz PWM). Kept as its own protocol until the sheet or the maker says what chip it is.
Datasheets disagree with themselves: the supply is 3.5-5.5 V in the feature list and absolute-maximum table (page 3) but the IC electrical table (page 4) gives VDD 2.5-5.5 V; the output-port rating is 10 V in the feature list but 16 V (BVout) in the maximum table and 14 V in the leakage test condition; operating temperature is -40 to +150 C in the maximum table and -20 to +70 C in the IC table header; and the LED optical table is quoted at IF = 20 mA while the driver sets 5 mA.
Refresh & flicker
PWM 1.0 kHz typical (page 5, Iout 5 mA, 200 ohm to VDD). Quiescent current 0.35 mA typical at 4.5 V. DIN input thresholds: high at least 2.8 V, low at most 1.6 V at VDD 5 V (page 4). The 5 mA output is the sheet’s default, with a 0.6 V saturation knee and 5 percent variation over -40 to +85 C.

| Reset is the “>=80us” in the page-5 refresh-cycle diagram. The sheet says “single-wire return-to-zero SID data protocol”, 800 kbps, 24 bits per pixel sent high bit first in G, R, B order (page 5 data-structure diagram). Code high/low times are not printed, so they are unknown rather than assumed. Propagation delay DIN to DOUT: 67 ns (L to H) and 93 ns (H to L) typical, 30 pF load; DOUT transition 15 / 23 ns. | ||||||||
Library support
Not checked. With no bit-timing table in the sheet, no library timing can be matched to it.

Dating evidence
Evidence, not a release date. A library commit proves the part existed by that date and says nothing about how long before.
