1 / 45 page HT46R47E/HT46C47E Cost-Effective A/D Type 8-Bit MCU Rev. 1.30 1 July 13, 2005 General Description The HT46R47E/HT46C47E are 8-bit, high perfor- mance, RISC architecture microcontroller devices spe- cifically designed for A/D applications that interface directly to analog signals, such as those from sensors. The mask version HT46C47E is fully pin and function- ally compatible with the OTP version HT46R47E de- vice. There are two dice in the HT46R47E/HT46C47E pack- age: one is the HT46R47/HT46C47 MCU, the other is a 128 ´8 bits EEPROM used for data memory purpose. The two dice are wire-bonded to form HT46R47E/ HT46C47E. The advantages of low power consumption, I/O flexibil- ity, programmable frequency divider, timer functions, oscillator options, multi-channel A/D Converter, Pulse Width Modulation function, HALT and wake-up func- tions, enhance the versatility of these devices to suit a wide range of A/D application possibilities such as sen- sor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc. Features · Operating voltage: fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V · 13 bidirectional I/O lines (max.) · 1 interrupt input shared with an I/O line · 8-bit programmable timer/event counter with overflow interrupt and 7-stage prescaler · On-chip crystal and RC oscillator · Watchdog Timer · 2048´14 program memory · 64´8 data memory RAM · 128´8 data EEPROM · Supports PFD for sound generation · HALT function and wake-up feature reduce power consumption · Up to 0.5ms instruction cycle with 8MHz system clock at VDD=5V · Six-level subroutine nesting · 4 channels 9-bit resolution A/D converter · 1 channel 8-bit PWM output shared with an I/O line · Bit manipulation instruction · 14-bit table read instruction · 63 powerful instructions · All instructions in one or two machine cycles · Low voltage reset function · 18-pin DIP/SOP package Technical Document · Tools Information · FAQs · Application Note - HA0049E Read and Write Control of the HT1380 - HA0051E Li Battery Charger Demo Board - Using the HT46R47 - HA0052E Microcontroller Application - Battery Charger - HA0083E Li Battery Charger Demo Board - Using the HT46R46 - HA0085E 8-bit Pseudo-Random Number Generator |
