1 / 77 page  HT46R46/C46/R47/C47/R48A/C48A/R49 Cost-Effective A/D Type 8-Bit MCU Rev. 1.30 1 June 5, 2008 General Description The Cost-Effective A/D Type MCU Devices are a series of 8-bit high performance RISC architecture microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors. All devices include an integrated multi-channel Analog to Digital Converter in addition to one or two Pulse Width Modulation outputs. The usual Holtek MCU features such as power down and wake-up functions, oscillator options, programmable frequency divider, etc. combine to ensure user applications require a minimum of external components. The benefits of integrated A/D and PWM functions, in addition to low power consumption, high performance, I/O flexibility and low-cost, provide these devices with the versatility to suit a wide range of application possibil- ities such as sensor signal processing, motor driving, in- dustrial control, consumer products, subsystem controllers, etc. Many features are common to all de- vices, however, they differ in areas such as I/O pin count, Program Memory capacity, A/D resolution, stack capacity and package types. Features · Operating voltage: fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V · 13 to 23 bidirectional I/O lines · External interrupt input shared with an I/O line · 8-bit programmable Timer/Event Counter with over- flow interrupt and 7-stage prescaler · On-chip crystal and RC oscillator · Watchdog Timer function · PFD for audio frequency generation · Power down and wake-up functions to reduce power consumption · Up to 0.5ms instruction cycle with 8MHz system clock at VDD=5V · 4 or 6-level subroutine nesting · 4 channels 8 or 9-bit resolution A/D converter · 1 or 2 channel 8-bit PWM output shared with I/O lines · Bit manipulation instruction · Table read instructions · 63 powerful instructions · All instructions executed in one or two machine cycles · Low voltage reset function · Range of packaging types Technical Document · Tools Information · FAQs · Application Note - HA0003E Communicating between the HT48 & HT46 Series MCUs and the HT93LC46 EEPROM - HA0049E Read and Write Control of the HT1380 - HA0051E Li Battery Charger Demo Board - Using the HT46R47 - HA0052E Microcontroller Application - Battery Charger - HA0075E MCU Reset and Oscillator Circuits Application Note - HA0083E Li Battery Charger Demo Board - Using the HT46R46 |
