167 / 202 page  RL78/G13 3. ELECTRICAL SPECIFICATIONS (G: INDUSTRIAL APPLICATIONS TA = -40 to +105 C) Page 167 of 196 R01DS0131EJ0330 Rev.3.30 Mar 31, 2016 3.5.2 Serial interface IICA (TA = 40 to +105C, 2.4 V EVDD0 = EVDD1 VDD 5.5 V, VSS = EVSS0 = EVSS1 = 0 V) HS (high-speed main) Mode Standard Mode Fast Mode Parameter Symbol Conditions MIN. MAX. MIN. MAX. Unit Fast mode: fCLK 3.5 MHz 0 400 kHz SCLA0 clock frequency fSCL Standard mode: fCLK 1 MHz 0 100 kHz Setup time of restart condition tSU:STA 4.7 0.6 s Hold time Note 1 tHD:STA 4.0 0.6 s Hold time when SCLA0 = “L” tLOW 4.7 1.3 s Hold time when SCLA0 = “H” tHIGH 4.0 0.6 s Data setup time (reception) tSU:DAT 250 100 ns Data hold time (transmission) Note 2 tHD:DAT 0 3.45 0 0.9 s Setup time of stop condition tSU:STO 4.0 0.6 s Bus-free time tBUF 4.7 1.3 s Notes 1. The first clock pulse is generated after this period when the start/restart condition is detected. 2. The maximum value (MAX.) of tHD:DAT is during normal transfer and a wait state is inserted in the ACK (acknowledge) timing. Caution The values in the above table are applied even when bit 2 (PIOR2) in the peripheral I/O redirection register (PIOR) is 1. At this time, the pin characteristics (IOH1, IOL1, VOH1, VOL1) must satisfy the values in the redirect destination. Remark The maximum value of Cb (communication line capacitance) and the value of Rb (communication line pull-up resistor) at that time in each mode are as follows. Standard mode: Cb = 400 pF, Rb = 2.7 k Fast mode: Cb = 320 pF, Rb = 1.1 k IICA serial transfer timing tR tBUF tF tLOW tHIGH tHD:STA Stop condition Start condition Restart condition Stop condition tSU:DAT tSU:STA tSU:STO tHD:STA tHD:DAT SCLAn SDAAn Remark n = 0, 1 <R> |
