HT46R71D-1 is Dual Slope A/D Type 8 – Bit OTP MCU that HOLTEK semiconductor put out newly, it accords with industrial specification, have OTP Partial Lock functions at the same time, applies to needing to store on the products which correct the data, can save the demand for extra EEPROM for the customer, and then cooperate with abundant and diversified functions, suitable for electric bridge quantity of sensor examine system especially, can person who use examine pressure, temperature, product that humidity changed, for instance: Counting, pressure gauge, thermometer, hygrometer of tire pressure,etc..

HT46R71D-1 specification includes 2K OTP ROM procedure memory, 32 Byte data storing device RAM , 16- bit Timer and 8 – each one of bit Timer, possess Buzzer hardware and output the function separately. Have foot of 10 I/O Pins altogether, possesses and wakes the function Wake-up up ,One Pin foot possesses the outside and stops touching off the function. Build LCD and drive the circuit inside, can drive 30 LCD Panel to the greatest extent. Have a pair of slope simulation figure changing device Dual Slope ADC, it is a kind of ADC -type attitude of examining the system of applying within HT46R71D-1 to amount extensively, this ADC includes operation amplifier, voltage and is up to coupling devices, integrators and comparators . And offer one to step up in circuit Charge Pump And the voltage stabilizer Regula tor of output 3.3V . To noise and the intersection of protection and the intersection of function and of low-voltage, offer, guard the gate dog Watch Dog too And LVD/LVR Low Voltage Detect/Low Voltage Reset Disposition.

HOLTEK semiconductor offers the multiple functional development tool of software and hardware, including artificial device In-Circuit-Emulator at the same time , burn the recording device, Windows based software development environment HT-IDE3000 , the intersection of C and the intersection of language and compiler and various employ guide,etc., suitable for need fast and efficient the intersection of procedure making and procedure and except that the intersection of user and application that track by mistake.

HT46R71D-1 supports 48SSOP to encapsulate and naked and brilliant, can already offer customer sample to ask for and produce and place an order at present.
