Notes 1.

Transfer rate in the SNOOZE mode is 4800 bps only.

Use it with VDD

≥ Vb.

The maximum operating frequencies of the CPU/peripheral hardware clock (fCLK) are:

HS (high-speed main) mode: 24 MHz (2.7 V

≤ VDD ≤ 5.5 V)

16 MHz (2.4 V

≤ VDD ≤ 5.5 V)

LS (low-speed main) mode: 8 MHz (1.8 V

≤ VDD ≤ 5.5 V)

The smaller maximum transfer rate derived by using fMCK/6 or the following expression is the valid

maximum transfer rate.

Expression for calculating the transfer rate when 4.0 V

≤ VDD ≤ 5.5 V and 2.7 V ≤ Vb ≤ 4.0 V

Maximum transfer rate =

[bps]

{–Cb × Rb × ln (1 –

2.2

Vb )} × 3

Transfer rate × 2 – {–Cb × Rb × ln (1 –

2.2

Vb )}

Baud rate error (theoretical value) =

× 100 [%]

(

Transfer rate ) × Number of transferred bits

* This value is the theoretical value of the relative difference between the transmission and reception sides.
