5 / 62 page  HT48R005/HT46R005 Rev. 1.00 5 November 29, 2011 General Description The HT46R005 and HT48R005 are a series of 8-bit high performance, RISC architecture microcontrollers spe- cifically 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= 12MHz: 2.2V~5.5V fSYS= 16MHz: 3.0V~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 freuency Crystal -- HXT External RC -- ERC Internal RC -- HIRC · Two operational modes: Normal, Sleep · Fully integrated internal 4MHz, 8MHz and 12MHz oscillator requires no external components · OTP Program Memory: 0.5K´14 · RAM Data Memory: 32´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 · 2-level subroutine nesting · Bit manipulation instruction · Low voltage reset function · Wide range of available package types Peripheral Features · 6 bidirectional I/O lines · 3 channel 12-bit ADC · External interrupt input shared with an I/O line · Single 8-bit programmable Timer/Event Counter with overflow interrupt and prescaler · Buzzer driving pair supported · Package types: 10-pin MSOP |
