S6E1C3 Series
Notes on Power-on
Turn power on/off in the following order or at the same time.
Turning on : VCC →AVRH
Turning off : AVRH →VCC
Serial Communication
There is a possibility to receive wrong data due to the noise or other causes on the serial communication.
Therefore, design a printed circuit board so as to avoid noise.
Consider the case of receiving wrong data due to noise; perform error detection such as by applying a checksum of data at the end.
If an error is detected, retransmit the data.
Differences in Features Among the Products with Different Memory Sizes and Between Flash Memory
Products and MASK Products
The electric characteristics including power consumption, ESD, latch-up, noise characteristics, and oscillation characteristics among
the products with different memory sizes and between Flash memory products and MASK products are different because chip
layout and memory structures are different.
If you are switching to use a different product of the same series, please make sure to evaluate the electric characteristics.
Pull-Up Function of 5 V Tolerant I/O
Please do not input the signal more than VCC voltage at the time of Pull-Up function use of 5 V tolerant I/O.
Handling when Using Debug Pins
When debug pins (SWDIO/SWCLK) are set to GPIO or other peripheral functions, set them as output only; do not set them as input.
