1 / 71 page HT46R01B/02B/01N/02N HT48R01B/02B/01N/02N Small Package 8-Bit OTP MCU Rev.1.10 1 February 12, 2010 General Description The Small Package MCUs are a series of 8-bit high per- formance, RISC architecture microcontrollers specifi- cally designed for a wide range of applications. The usual Holtek microcontroller features of low power con- sumption, I/O flexibility, timer functions, oscillator op- tions, power down and wake-up functions, watchdog timer and low voltage reset, combine to provide devices with a huge range of functional options while still main- taining a high level of cost effectiveness. The fully inte- grated system oscillator HIRC, which requires no external components and which has three frequency selections, opens up a huge range of new application possibilities for these devices, some of which may in- clude industrial control, consumer products, household appliances subsystem controllers, etc. Features CPU Features · Operating voltage: fSYS= 4MHz: 2.2V~5.5V fSYS= 8MHz: 3.0V~5.5V fSYS= 12MHz: 4.5V~5.5V · Up to 0.33ms instruction cycle with 12MHz system clock at VDD=5V · Sleep mode and wake-up functions to reduce power consumption · Oscillator types: External high frequency Crystal External RC Internal RC External low frequency crystal Watchdog Timer internal RC oscillator · Three operational modes: Normal, Slow, Sleep · Fully integrated internal 4MHz, 8MHz and 12MHz oscillator requires no external components · OTP Program Memory: 1K´15~2K´15 · RAM Data Memory: 96´8 · Watchdog Timer function · LIRC oscillator function for watchdog timer · All instructions executed in one or two instruction cycles · Table read instructions · 63 powerful instructions · 6-level subroutine nesting · Bit manipulation instruction · Low voltage reset function · 10-pin MSOP, 16-pin NSOP package types Peripheral Features · Up to 10 bidirectional I/O lines · 4 channel 12-bit ADC · 1 channel 8-bit PWM · External interrupt input shared with an I/O line · Two 8-bit programmable Timer/Event Counter with overflow interrupt and prescaler · Time-Base function · Programmable Frequency Divider - PFD Technical Document · Application Note - HA0075E MCU Reset and Oscillator Circuits Application Note |
