One channel distance measurement photo IC for indirect TOF (time-of-flight) The S13021-01CT is a distance measurement device using the indirect TOF method. It integrates Hamamatsu’s CMOS sensor and signal processing circuit. The sensor outputs signals proportional to the time for the pulse-modulated light to reﬂect by the target object and return. The output value can be used to calculate the distance to the target object. The S1302101CT runs on low voltage (3.3 V) and supports I2C interface and SPI. Distance measurement Presence or absence of objects Structure Parameter Speciﬁcation 0.4 × 0.4 Glass epoxy Epoxy resin Photosensitive area Package Seal material Absolute maximum ratings (Ta=25 °C) Parameter Symbol Value Supply voltage Vdd -0.3 to +4.6 Load current Io ±10 Power dissipation P 100 Operating temperature Topr -25 to +65 Storage temperature Tstg -40 to +85 Soldering temperature Tsol 240 (once)*1 *1: Reﬂow soldering, IPC/JEDEC J-STD-020 MSL 5a, see P.14 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to product within the absolute maximum ratings.
