Caution

The pins mounted depend on the product. Refer to 1.3.1 30-pin products to 1.3.10 100-pin products.

2.2.2

On-chip oscillator characteristics

Note 1.

High-speed on-chip oscillator frequency is selected with bits 0 to 4 of the option byte (000C2H/010C2H) and bits 0 to 2 of

the HOCODIV register.

Note 2.

This only indicates the oscillator characteristics. Refer to AC Characteristics for instruction execution time.

When SSOP (30-pin), WQFN (32-, 40-, 48-pin), FLGA (36-pin), LQFP (7 × 7) (48-pin), LQFP (10 × 10) (52-pin), LQFP

(12 × 12) (64-, 80-pin), LQFP (14 × 14) (80-, 100-pin), LQFP (14 × 20) (100-pin) products, these specifications show

target values, which may change after device evaluation.
