HT83F22数据手册Holtek中文资料规格书

描述 Description

The HT83F22 is an A/D type 8-bit high performance Flash Memory MCU which includes a digital voice recorder, synthesizer and tone generator. It is specifically designed for applications which require multiple I/Os and sound effects, such as voice and melodies. Additionally, it can provide various sampling rates and beats, tone levels, tempos for speech synthesisers and melody generators. Furthermore, with the internal amplifer, auto gain control, SCF filter and the fast 12-bit A/D converter features, this device provides a means of implementing digital audio recorder applications. Offering users the convenience of Flash Memory multi-programming features, this device also includes a wide range of functions and features. Analog features include a multi-channel 12-bit A/D converter and comparator. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully integrated SPI or I2C interface functions, two popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.It also includes an integrated high quality, voltage type DAC output, a two-stage amplifier with Auto Gain Control for microphone input signal amplification and a power amplifier for speaker driving. The external interrupt can be triggered with falling edges or both falling and rising edges.
A full choice of HXT, LXT, ERC, HIRC and LIRC oscillator functions are provided including a fully integrated system oscillator which requires no external components for its implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimise power consumption.
The inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the devices will find excellent use in applications such as voice recorder, answering machine, electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.
This device is fully supported by the Holtek range of fully functional development and programming tools, providing a means for fast and efficient product development cycles.
