The Holtek launch new eight 12 Bit the A / D-type microcontroller --- HT46R51/52/53/54 

 2/25/2005 


 HT46R51, HT46R52, HT46R53, HT46R54 new development is Holtek completed eight General Purpose 12-bit A / D Series microcontrollers, 1k, 2k, 2k, 4k, the OTP program memory. Internal features include a precision high 12 Bit ADC converter and PWM output function. The level of the ADC based on the product ranging from five-channel and 8 channel ADC reference voltage by the external VREF the Pin input. Respectively 14, 22 I / O port according to the grade of products for customers the flexibility to control the use. The full range of products to 88 a Byte Data RAM and an 8-bit the Timer and an external interrupt function to receive the external trigger signal. In addition, the PFD output, which can produce the audio signal. This series of products, high anti-noise characteristics as the Holtek other 8-Bit MCU with Watchdog (Watchdog) and LVR function to strengthen the ability of the MCU anti-crash. 

 HT46R51, HT46R52, HT46R53, HT46R54 with 12 Bit ADC to detect the external sensor signal changes, and with excellent value for money. Especially suitable for field application of the battery charger. External controller, all kinds of small appliances and other products use in the car are very appropriate. 

 This series of products currently HT46R51, HT46R52 provide the 18-pin both the DIP and 20-pin SSOP package type. HT46R53, HT46R54 then the-the pin SKDIP 28 and 28-pin the SOP and other two package types.
