100-pin products

• 100-pin plastic LFQFP (14 × 14 mm, 0.50-mm pitch)

Caution 1. Connect the EVSS pin to the same ground as the VSS pin.

Caution 2. Connect the REGC pin to VSS via a capacitor (0.47 to 1 µF).

Remark 1. For pin identification, see 1.4 Pin Identification.

Remark 2. When using the microcontroller for an application where the noise generated inside the microcontroller must be reduced,

it is recommended to connect the VSS and EVSS pins to separate ground lines.

Remark 3. Functions in parentheses can be assigned via settings in the peripheral I/O redirection registers (PIORx). For details, see

4.3.10 Peripheral I/O redirection registers (PIORx) in the RL78/L23 User’s Manual.
