Holtek New Product Release - HT46RU67 and HT46CU67 A/D with LCD Type Microcontroller

03/11/2008

Following on from Holtek’s A/D with LCD type MCU HT46R6x series present new releases, the HT46R65/652 and HT46RU66, now comes the new HT46RU67 and HT46CU67. These two new devices increase the application resources of this device series, expandind thier application areas and providing the user with yet further flexibility and choices.

The HT46RU67 and HT46CU67 devices contain 32K x16-bits of Program Memory, with the HT46RU67 as an OTP type and the HT46CU67 as Mask type. The devices contain 768 bytes of SRAM Data Memory, and the internal LCD Driver supports either 46x4 or 47x3 Pixel outputs. Their 32 I/O pins supply the user with a means for external device output and input control. The internal 12-bit resolution analog to digital converter and 8-bit PWM output, can be used for external analog signal monitoring and for control of temperature, motor speed, voltage, current etc.

The HT46RU67/HT46CU67 devices, in addition to their internal SPI interface can also form a bridge to other systems. The internal hardware UART interface, belongs to the full duplex asynchronous type design type whose Baud Rate can be adjusted by software. The UART function also contains automatic error detection flag functions. Because the UART function is implemented internally in hardware, it reduces the demands on software, ensuring maximum efficiency from the MCU.

As one of Holtek’s new generation of 8-bit microcontrollers , the HT46RU67 and HT46CU67 fully meet with industrial specifications and are supplied in three package types, 52-pin QFP, 56-pin SSOP and 100-pin QFP. The devices are suitable for use in application areas such as household electrical appliances which require a display, exercise equipment, medical equipment and industrial controllers etc.

Fully supporting these new devices is Holtek’s Windows based HT-IDE3000 range of hardware and software development tools. A full range of features are included in the development system such as In-circuit Emulator, full trace facilities, integrated device programmer etc. ensuring that product designers have all the necessary tools to hand to ensure that their products are designed and debugged as rapidly and efficiently as possible.
