80-pin products

• 80-pin plastic LQFP (14 × 14 mm, 0.65-mm pitch)

• 80-pin plastic LFQFP (12 × 12 mm, 0.50-mm pitch)

Caution

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. 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.
