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.
In its capacity as a specialised remote-control device, one distinctive internal feature is its ability to generate a carrier frequency via an internal programmable frequency divider (PFD) output.
As the carrier frequency is under software control, the device has the flexibility to suit a wide range of universal remote control (URC) applications.
Other features include: one 8bit and one 16bit internal timer/event counter, one external interrupt and an eight-level stack, 224 x 8bit of internal RAM and 23 I/O pins.
Program memory is subdivided into three areas, each of which has a capacity of 8K x 16bit.
With an operating voltage range between 2.2 and 3.6V the processor is suitable for all two-cell battery applications.
Operating frequency ranges from 400kHz to 4MHz.
An internal power down function ensures a supply current of less than 1mA when the device is in the low power mode.
The device has full pin and functional compatibility with its sister OTP device, the HT48RA3.
The HT48RA3 OTP device, is available to give designers the necessary programming flexibility during the product development and market evaluation stages to reduce the risks involved before moving into high volume mask device production.
Devices are available in 28-pin SKDIPs and SOPs.
