HT46R01T3/HT48R01T3
8-Bit OTP MCU with RF Transmitter
General Description
These devices provide a combination of a fully featured MCU plus an RF transmitter function, giving
them great flexibility for use in wide range of wireless I/O control applications such as industrial
control, consumer products, subsystem controllers, etc.
Analog features include a multi-channel 12-bit A/D converter. Multiple and extremely flexible
Timer/Event Counters provide full timing functions. Protective features such as an internal Watchdog
Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that
reliable operation is maintained in hostile electrical environments. An extensive choice of 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 devices also include flexible I/O programming
features Time-Base functions and a range of other features.
The RF transmitter is a high performance and easy to use transmitter operating in the 300MHz to
450MHz frequency band. One only needs to add a crystal reference frequency, and a limited number of
external components to create a complete and versatile RF transmitter system. The device is capable of
delivering more than +9dBm into a 50W load. Such a power level enables a small form factor
transmitter to operate near the maximum limit of the transmission regulations. The device can operate
with ASK - Amplitude Shift Keying, and OOK - On-Off Keying, UHF receiver types from wide-band
super-regenerative radios to narrow-band, high performance super-heterodyne receivers. The data rate
is higher than 10kbps, allowing the device to support more complicated control protocols.
For enhanced power saving, the device includes a data tracking function. The data tracking function
enables the PLL to be activated as long as high transient data input trigger signals are received. The
PLL will also be automatically switched off if there are no data input transients for a time exceeding
approximately 300ms. As there is a reference clock input on line PB0, the MCU can use its internal RC
clock rather than using an additional crystal for the system clock. These features add up to ensure that
the devices can offer excellent capabilities in terms of functionality and power-saving as well as being
highly cost effective in a huge range of remote wireless applications
