Note:

1. There are additional peripherals named RF Transceiver with RF frequency of 2.4GHz and Data EEPROM

with capacity of 128 bytes in HT82M75REW and HT82K75REW devices. All information related to the

RF Transceiver and EEPROM Data Memory will be described in the corresponding section respectively.

2. As devices exist in more than one package format, the table reflects the situation for the package with the

most pins.
