HT82M9BAE Datasheet | Holtek Semiconductor

Features - Flexible total solution for applications that bine - 6MHz/12MHz internal CPU clock - 8-level stacks - Two 8-bit indirect addressing registers - One 8-bit programmable timer counter with overflow PS/2 and low-speed USB interface, such as mice, joysticks, and many others - USB Specification pliance - Conforms to USB specification V1.1 - Conforms to USB HID specification V1.1 - Supports 1 low-speed USB control endpoint and interrupt (shared with PA6, vector 08H) - One 16-bit programmable timer counter with 3 interrupt endpoint - Each endpoint has 8´8 bytes FIFO - Integrated USB transceiver - 3.3V regulator output - External 6MHz or 12MHz ceramic resonator or crystal - 8-bit RISC microcontroller, with 8K´16 program 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) - 20 I/O ports - 24/28-pin SOP package memory (0000H~1FFFH) - 224´8 bytes RAM (20H~FFH) - EEPROM 128´8 data memory 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. The mask version HT82M9BAE is fully pin and functionally patible with the OTP version HT82M9BEE device. There are two dice in the HT82M9BEE/HT82M9BAE package: one is the HT82M9BE/HT82M9BA MCU, the other is a 128´8 bits EEPROM used for data memory purpose. The two dice are wrie-bonded to from HT82M9BEE/ HT82M9BAE. Rev. 1.20 August 13, 2007 HT82M9BEE/HT82M9BAE ..
