1 / 88 page  HT46F46E/HT46F47E/HT46F48E/HT46F49E Cost-Effective A/D Flash Type 8-Bit MCU with EEPROM Rev. 1.40 1 July 28, 2009 General Description The Cost-Effective A/D Flash Type MCU with EEPROM Devices are a series of 8-bit high performance RISC ar- chitecture microcontrollers, designed especially for ap- plications 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 fSYS=12MHz: 4.5V~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 · Flash program memory can be re-programmed up to 100,000 times · EEPROM data memory can be re-programmed up to 1,000,000 times · Flash program memory data retention > 10 years · EEPROM data memory data retention > 10 years · ISP (In-System Programming) interface · Range of packaging types Technical Document · Tools Information · FAQs · Application Note - HA0052E Microcontroller Application - Battery Charger - HA0075E MCU Reset and Oscillator Circuits Application Note - HA0123E HT48F MCU Series - Using C Language to Write to the 1K EEPROM Data Memory - HA0125E HT48F MCU Series - Using C Language to Write to the 2K EEPROM Data Memory |
