Industrial MCUs take analogue onboard
Devices include a dual slope analogue to digital convertor with an operational amplifier, a voltage follower, integrator and comparator functions.
MCU sounds a good idea for audio systems
The HT82A836R includes a fully integrated sigma-delta type audio codec to provide a high resolution analogue to digital convertor function.
Each category is divided according to the level of its internal resources, however each category has the choice of either OTP or mask devices, providing solutions to both low- and high-volume requirements.
With their internal ROM/RAM memory, interrupts, power down and wake-up features as well as their flexible pin shared LCD pin arrangement and dual operating frequency modes as well as two modes of power down, internal dialler I/O etc, the devices have the features and flexibility to meet the needs of a wide range of telephone related equipment.
In addition to handset applications, because these telephone controllers are equipped with substantially more resources than the standard range of MCUs, the needs of other communication devices such as small/medium PBXs, communication systems, intelligent building management systems, and other consumer and home appliance devices can all be met by these new Holtek telephone controllers.
The provision of OTP devices permits evaluation samples and small volume runs to be produced, meeting the demands of low time to market constraints.
Mask devices are available for high volume product runs providing a means of increasing further the competitive advantages of caller ID telephone related products.
