General Description
The USB MCU OTP body is suitable for USB mouse
and USB joystick devices. It consists of a Holtek high
performance 8-bit MCU core for control unit, built-in
USB SIE, 4K´15 ROM and 224 bytes data RAM.
The mask version HT82M9AAE is fully pin and function-
ally compatible with the OTP version HT82M9AEE device.
· 128´8 data EEPROM
· 6MHz/12MHz internal CPU clock
· 4-level stacks
· Two 8-bit indirect addressing registers
· One 16-bit programmable timer counter with
overflow interrupt (shared with PA7, vector 0CH)
· One USB interrupt input (vector 04H)
· HALT function and wake-up feature reduce power
consumption
· PA0~PA7, PB4/SDA and PB7/SCL support wake-up
function
· Internal Power-On reset (POR)
· Watchdog Timer (WDT)
· 16 I/O ports
· 20/24-pin SOP package
There are two dice in the HT82M9AEE/HT82M9AAE
package: one is the HT82M9AE/HT82M9AA MCU, the
other is a 128´8 bits EEPROM used for data memory
purpose. The two dice are wrie-bonded to from
HT82M9AEE/HT82M9AAE.
