With their integrated 8bit to 9bit internal ADC, the new HT46R46, HT46R46E and HT46R47E 8bit MCU devices from Holtek Semiconductor provide three new MCU device solutions in the cost-effective A/D series range, said the press release.

The HT46R46 uses an 8bit MCU core from the company, and has a maximum operating frequency of 8MHz and a 1K word Program Memory. Its integrated peripheral functions include a 4-channel 8bit ADC which can process external environmental signals such as those of temperature and humidity. Other integrated functions include a Pulse Width Modulation (PWM) output, which has applications in motor control, and 13 available I/O pins that can be used for standard I/O control functions. The addition of a Programmable Frequency Divider (PFD), which can provide a range of audio frequencies, in addition to other integrated functions, provides product designers with an extremely flexible and highly functional device with which to implement a wide range of applications, shared Holtek.

The HT46R46E and the HT46R47E incorporate two integrated circuits, an 8bit MCU device and a 1K bit Data EERPOM into a single device package. Although incorporating an EEPROM, both products are functionally similar to their sister devicesthe HT46R46 and the HT46R47.

By providing users with a superior range of features, added the company, these products are extremely suited for use in a range of household appliance, automotive peripheral and other intelligent controller product applications.

The HT46R46, HT46R46E and HT46R47E devices are all available in 18-pin SOP/SKDIP package types.
