R5F100LEAFB Electrical Characteristics
This chapter describes the following electrical specifications.
Target products A: Consumer applications TA = -40 to +85°C R5F100xxAxx, R5F101xxAxx
- D: Industrial applications TA = -40 to +85°C R5F100xxDxx, R5F101xxDxx
- G: Industrial applications when TA = -40 to +105°C products is used in the range of TA = -40 to +85°C R5F100xxGxx
- Cautions 1. The RL78 microcontrollers have an on-chip debug function, which is provided for development and evaluation. Do not use the on-chip debug function in products designated for mass production, because the guaranteed number of rewritable times of the flash memory may be exceeded when this function is used, and product reliability therefore cannot be guaranteed. Renesas Electronics is not liable for problems occurring when the on-chip debug function is used.
- With products not provided with an EVDD0, EVDD1, EVSS0, or EVSS1 pin, replace EVDD0 and EVDD1 with VDD, or replace EVSS0 and EVSS1 with VSS.
- The pins mounted depend on the product. Refer to 2.1 Port Function to 2.2.1 Functions for each product in the RL78 User's Manual.

- Notes 1. Connect the REGC pin to Vss via a capacitor (0.47 to 1 μF). This value regulates the absolute maximum rating of the REGC pin. Do not use this pin with voltage applied to it.
- Must be 6.5 V or lower.
- Do not exceed AVREF(+) + 0.3 V in case of A/D conversion target pin .
Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded.
- Remarks 1. Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port pins.
- AVREF (+) : + side reference voltage of the A/D converter.
- VSS : Reference voltage
