General Description
The USB MCU HT82M99EE/HT82M99AE are suitable
for USB mouse devices. It consists of a Holtek high per-
formance 8-bit MCU core for control unit, built-in USB
SIE, 2K´14 program memory and 96 bytes data RAM.
The mask version HT82M99AE is fully pin and functionally
compatible with the OTP version HT82M99EE device.
There are two dice in the HT82M99EE/HT82M99AE
package: one is the HT82M99EE/HT82M99AE MCU,
the other is a 128´8 bits EEPROM used for data mem-
ory purpose. The two dice are wire-bonded to form
HT82M99EE/HT82M99AE.
