General Description
The USB MCU OTP body is suitable for USB mouse de-
vices. It consists of a Holtek high performance 8-bit
MCU core for control unit, built-in USB SIE, 2K´14 ROM
and 96 bytes data RAM.
The mask version HT82M99A is fully pin and functionally
compatiblewww.DataSheet.net/ with the OTP version HT82M99E device.
