CSI mode connection diagram (during communication at different potential)
Caution Select the TTL input buffer for the SIp, SCKp and SSIp pins and N-ch open-drain output mode for the
SOp pin.
Remarks 1. Rb [Ω]: Communication line (SOp) pull-up resistance, Cb [F]: Communication line (SOp) load capacitance,
V
b [V]: Communication line voltage
2. p: CSIp (p = 00, 01, 10, 11), m: Unit m (m = 0, 1), n: Channel n (n = 0, 1)
3. AC characteristics of the serial array unit during communication at different potential in CSI mode are
measured with the
VIH and VIL below:
When 4.0 V  EVDD0  5.5 V, 2.7 V  Vb  4.0 V: VIH = 2.2 V, VIL = 0.8 V
