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, 8K´16 ROM and 224 bytes data RAM.
· 8-level stacks
· Two 8-bit indirect addressing registers
· One 8-bit programmable timer counter with overflow
interrupt (shared with PA6, vector 08H)
· 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 and PB7 support wake-up function
· Internal Power-On reset (POR)
· Watchdog Timer (WDT)
· 20 I/O ports
· 24/28-pin SSOP package
32-pin QFN package
The mask version HT82M9BA is fully pin and functionally
compatible with the OTP version HT82M9BE device.
