Holtek 公司的HT48R065V 是24V VFD 型8位OTP MCU, 可直接驱动12~24V的VFD(真空荧光显示屏) , 內建5V LDO輸出,可將輸入的12~24V高压转换為5V电压供給MCU Core及外部5V元件,並內建高压Buzzer 驱动器与灯絲(Filament)高压輸出,可大幅精簡VFD應用的顯示驅動、電源處理等電路設計. 目标应用为家電、音響、DVD 播放器、STB及汽車等.本文介绍HT48R065V主要特性,方框图, 系统时钟配置框图,各种I/O端口图和典型应用电路图.

HT48R065V 24V VFD Type 8-Bit OTP MCU

The 48R065V is a 24V VFD Type 8-bit high performance, RISC architecture microcontrollers specifically designed for a wide range of applications. The usual Holtek microcontroller features of low power consumption, I/O flexibility, timer functions, oscillator options, power down and wake-up functions, watchdog timer and low voltage reset, combine to provide devices with a huge range of functional options while still maintaining a high level of cost effectiveness. The fully integrated system oscillator HIRC, which requires no external components and which has three frequency selections, opens up a huge range of new application possibilities for these devices, some of which may include industrial control, consumer products, household appliances subsystem controllers, etc.
