ELECTRICAL SPECIFICATIONS (TA = –40 to +85°C) R01DS0131EJ0350 Rev.3.50 118 of 200 Jun 30, 2020 2.9 Dedicated Flash Memory Programmer Communication (UART) (TA = –40 to +85°C, 1.8 V ≤ EVDD0 = EVDD1 ≤ VDD ≤ 5.5 V, VSS = EVSS0 = EVSS1 = 0 V) Parameter Symbol Conditions MIN. TYP. MAX. Unit Transfer rate During serial programming 115,200 1,000,000 bps 2.10 Timing of Entry to Flash Memory Programming Modes (TA = –40 to +85°C, 1.8 V ≤ EVDD0 = EVDD1 ≤ VDD ≤ 5.5 V, VSS = EVSS0 = EVSS1 = 0 V) Parameter Symbol Conditions MIN. TYP. MAX. Unit Time to complete the communication for the initial setting after the external reset is released tSUINIT POR and LVD reset must be released before the external reset is released. 100 ms Time to release the external reset after the TOOL0 pin is set to the low level tSU POR and LVD reset must be released before the external reset is released. 10 µs Time to hold the TOOL0 pin at the low level after the external reset is released (excluding the processing time of the firmware to control the flash memory) tHD POR and LVD reset must be released before the external reset is released. 1 ms RESET TOOL0 <1> <2> <3> tSU <4> tSUINIT 723 µs + tHD processing time 1-byte data for setting mode <1> The low level is input to the TOOL0 pin. <2> The external reset is released (POR and LVD reset must be released before the external reset is released.). <3> The TOOL0 pin is set to the high level. <4> Setting of the flash memory programming mode by UART reception and complete the baud rate setting. Remark tSUINIT: Communication for the initial setting must be completed within 100 ms after the external reset is released during this period. tSU: Time to release the external reset after the TOOL0 pin is set to the low level tHD: Time to hold the TOOL0 pin at the low level after the external reset is released (excluding the processing time of the firmware to control the flash memory) |
