24V VFD MCU series from Holtek targeting household and STB apps

Holtek has released the HT48R065V, HT46R065V, HT45R35V and HT45R37V, a new 24V VFD device series that can directly drive a 12 to 24V VFD panel - vacuum fluorescent display with its embedded VFD driver. These VFD device series is suitable for the applications such as household appliances, stereos, DVD players, Set-top Boxes, and car appliances.

The HT48R065V as an I/O type MCU, the HT46R065V as an A/D type MCU and the HT45R35V and HT45R37V as Touch Switch type MCUs, these devices also include an integrated LDO to generate a 5V to supply the MCU core and the external 5V components. Its internal high voltage Buzzer Driver circuit and Filament high voltage output ensure that the external component requirements are kept to a minimum.

The key features of the new 24V VFD MCU series are,

Program memory capacity of 2K to 4K
Data memory SRAM capacity of 96 to 160 bytes, from 11 to 17 I/O pins and one or two 8/16-bit timers
In addition to the usual crystal and external RC oscillators, the precise internal RC oscillator, with the exception of the HT45R35V, provides 3 fixed frequencies at 4, 8 and 12Mhz
The HT46R065V and HT45R37V devices also include a 12-bit high speed ADC and 8/12 bit PWM
The HT45R35V and HT45R37V includes 9 to 12 C/R-F channels can be used to easily implement touch switch functions.

Package: 52 QFP package
