1 / 94 page  HT48R063/064/065/066/0662/067 Enhanced I/O Type 8-Bit OTP MCU Rev. 1.30 1 June 11, 2010 General Description The Enhanced I/O 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 · Idle/Sleep mode and wake-up functions to reduce power consumption · Oscillator types: External high freuency Crystal -- HXT External RC -- ERC Internal high frequency RC -- HIRC External low frequency crystal -- LXT · Four operational modes: Normal, Slow, Idle, Sleep · Fully integrated internal 4MHz, 8MHz and 12MHz oscillator requires no external components · Watchdog Timer function · LIRC oscillator function for watchdog timer · All instructions executed in one or two instruction cycles · Table read instructions · 63 powerful instructions · Up to 8-level subroutine nesting · Bit manipulation instruction · Low voltage reset function · Wide range of available package types Peripheral Features · Up to 42 bidirectional I/O lines · Software controlled 4-SCOM lines LCD COM driver with 1/2 bias · External interrupt input shared with an I/O line · Up to three 8-bit programmable Timer/Event Counter with overflow interrupt and prescaler · Time-Base function · Programmable Frequency Divider - PFD · Up to 3 channel 8-bit PWM Technical Document · Application Note - HA0075E MCU Reset and Oscillator Circuits Application Note |
