HT82K95AE数据手册Holtek中文资料规格书

描述 Description

This device is an 8-bit high performance RISC architecture microcontroller designed for USB product applications. It is particularly suitable for use in products such as keyboards. A HALT feature is included to reduce power consumption. The mask version HT82K95AE is fully pin and functionally compatible with the OTP version HT82K95EE device.
There are two dice in the HT82K95EE/HT82K95AE package: one is the HT82K95E/HT82K95A MCU, the other is a 128×8  bits EEPROM used for data memory purpose. The two dice are wire-bonded to form HT82K95EE/HT82K95AE.
