The low-current IC of the 3.0 x 1.0 mm Bright LED pixel. Same cell as the BB-HRGB32K but with a 6 mA drive and a different, slower timing table (T0L 1.0 us typ, T1L 0.7 us typ, reset 150 us typ) - kept separate from aboc-bb because the tables differ.

Refresh & flicker

6 mA per channel, 800 kHz, static current 0.5 mA at 4.5 V, delay 80 ns, DIN thresholds 0.7 / 0.3 VDD, power consumption 0.1 W (feature list). R, G, B order, MSB first (‘Follow the order of RGB’).
