Holtek New HT82K75Rx / HT82M75Rx series of 2.4GHz Wireless MCUs

April 2, 2010

After the successful release of its of 27MHz wireless solution range, Holtek takes pleasure in the announcement of its new series of 2.4GHz wireless devices. With a high level of functional integration, high performance, low power consumption and low cost these devices offer users excellent performance/price ratios. This new device series can be used together with other different 2.4GHz RF ICs. These MCU devices are aimed squarely at a diverse range of wireless applications and have already achieved excellent market feedback.

The high level of functional integration in the HT82K75R/HT82M75R sees the devices fully equipped with an internal DC-DC converter and high speed 6MHz oscillator circuit which reduce the need for an external voltage regulator or oscillator components. These integrated features minimize the need for external components and consequently reduce overall product costs. The HT82K75R/HT82M75R devices contain 160 and 128 bytes of Data Memory and up to 40 and 24 I/O pins respectively. Both devices contain 4Kx15 of Program Memory and have an integrated SPI circuit. The HT82K75RE/HT82M75RE devices also contain 128 bytes of EEPROM, which reduce the need to add an external EEPROM and therefore reduce PCB area requirements and result in lower costs and higher competitiveness.

This device series is suitable for battery powered 2.4GHz wireless applications such as wireless keyboard/mouse, remote controllers, wireless presenters and so on. The HT82K75R/HT82K75RE devices are available in 48-pin SSOP packages while the HT82M75R is available in 20/28-pin SOP, 28-pin SSOP and 32-pin QFN package types. The HT82M75RE is only available in 32-pin QFN package types. All devices are available as customer samples or in volume orders.

The devices are as usual fully supported by Holtek’s suite of the windows based HT-IDE3000 development tools. Included in this set of tools is an in-circuit-emulator which with features such as read/write functions, hardware breakpoints with logical setups, trace analyzer etc. all of which combine to ensure that designers have their products designed as efficiently and rapidly as possible.
