1 / 42 page  HT46R46/HT46C46/HT46R47/HT46C47 Cost-Effective A/D Type 8-Bit MCU Rev. 1.00 1 December 28, 2004 General Description The HT46R46/HT46C46 and HT46R47/HT46C47 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for A/D applications that interface directly to analog signals, such as those from sensors. The mask version HT46C46, HT46C47 are fully pin and functionally com- patible with the OTP version HT46R46, HT46R47 de- vice. 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 · 1024´14 program memory for HT46R46/HT46C46 · 2048´14 program memory for HT46R47/HT46C47 · 64´8 data memory RAM · 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 · 4-level subroutine nesting for HT46R46/HT46C46 · 6-level subroutine nesting for HT46R47/HT46C47 · 4 channels 8-bit resolution A/D converter for HT46R46/HT46C46 · 4 channels 9-bit resolution A/D converter for HT46R47/HT46C47 · 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 |
