CHAPTER 31 ELECTRICAL SPECIFICATIONS
(2) Serial interface: Serial array unit (9/18)
Remarks 1. Rb[Ω]:Communication line (TxDq) pull-up resistance, Cb[F]: Communication line (TxDq) load
capacitance, Vb[V]: Communication line voltage
2. q: UART number (q = 0 to 3) , g: PIM number (g = 1, 7), x: POM number (x = 1, 7, 8)
3. fMCK: Serial array unit operation clock frequency
(Operation clock to be set by the CKSmn bit of the SMRmn register. m: Unit number (m = 0, 1),
n: Channel number (n = 0, 2))
4. VOH and VoL below are observation points for the AC characteristics of the serial array unit when
communicating at different potentials in UART mode.
4.0 V ≤ VDD = EVDD ≤ 5.5 V, 2.7 V ≤ Vb ≤ 4.0 V: VOH = 2.2 V, VoL = 0.8 V
2.7 V ≤ VDD = EVDD < 4.0 V, 2.3 V ≤ Vb < 2.7 V: VOH = 2.0 V, VoL = 0.5 V
