HT82K95EE/HT82K95AE USB Keyboard MCU with EEPROM

March 6, 2006

Two new USB keyboard OTP microcontrollers devices, in the form of the HT82K95EE/ HT82K95AE, have just been released to complement the already released HT82K95E/HT82K95A devices, expanding yet further Holtek's PC peripheral device range. With a host of integrated functions, design convenience, and competitive pricing, the existence of these two new devices will provide related PC peripheral vendors with an even further choice for their products. Holtek, as a leading domestic competitive company, in providing these highly stable and compatible devices provides the means for customers from domestic and overseas regions to design their products in as quickly a time as possible. 

The two new HT82K95EE/ HT82K95AE USB keyboard devices include an internal EEPROM data memory of 128 bytes capacity and meet the specification for USB HID 1.1 compatible products. Each device includes 128 bytes of internal EEPROM data memory in addition to 4K X 15 of Program Memory, 160 bytes of conventional Data Memory and 32 I/O lines. The memory capacity of the devices is well within the requirements of most related USB products. The devices would be suitable for use in products such as Boot Device Keyboards, Mouse products and also suitable for products which have both PS2 and USB interfaces for which auto-detection is required. The devices allow the facility for customers to add their own VID, PID, product strings etc variables, or to include other special design needs.
