Caution The pins mounted depend on the product. Refer to 2.1.1 20-pin products to 2.1.14 128-pin products,
and 2.1.15 Pins for each product (pins other than port pins).

Notes 1. Transfer rate in the SNOOZE mode : MAX. 1 Mbps
2. Use it with EVDD0 ≥ Vb.
3. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp setup time becomes “to SCKp↓”
when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
4. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The SIp hold time becomes “from SCKp↓”
when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
5. When DAPmn = 0 and CKPmn = 0, or DAPmn = 1 and CKPmn = 1. The delay time to SOp output becomes
“from SCKp↑” when DAPmn = 0 and CKPmn = 1, or DAPmn = 1 and CKPmn = 0.
Caution Select the TTL input buffer for the SIp pin and SCKp pin and the N-ch open drain output (V
DD tolerance)
mode for the SOp pin by using port input mode register g (PIMg) and port output mode register g
(POMg).

b[Ω]:Communication line (SOp) pull-up resistance, Cb[F]: Communication line (SOp) load capacitance,
V
b[V]: Communication line voltage
2. p: CSI number (p = 00, 01, 10, 20, 30, 31), m: Unit number (m = 0, 1), n: Channel number (n = 00, 01, 02, 10,
12, 13), g: PIM and POM number (g = 0, 1, 4, 5, 8, 14)
3. f
MCK: Serial array unit operation clock frequency
(Operation clock to be set by the CKSmn bit of serial mode register mn (SMRmn).
m: Unit number, n: Channel number (mn = 00, 01, 02, 10, 12, 13))
4. V
IH and VIL below are observation points for the AC characteristics of the serial array unit when
communicating at different potentials in CSI mode.
4.0 V ≤ EV
DD0 ≤ 5.5 V, 2.7 V ≤ Vb ≤ 4.0 V: VIH = 2.2 V, VIL = 0.8 V
2.7 V ≤ EV
DD0 < 4.0 V, 2.3 V ≤ Vb ≤ 2.7 V: VIH = 2.0 V, VIL = 0.5 V
1.8 V ≤ EV
DD0 < 3.3 V, 1.6 V ≤ Vb ≤ 2.0 V: VIH = 1.5 V, VIL = 0.32 V
5. CSI01 of 48-, 52-, 64-pin products, and CSI11 and CSI21 cannot communicate at different potential. Use
other CSI for communication at different potential.
