TM52FN8273/76/74/78 integrates a high-efficiency F51 core, with a precise 12-bit A/D converter,
as well as low-power clock and LCD or LED display functions, suitable for small home appliance applications.
In terms of specifications, it meets the performance requirements of -40℃~85℃ working temperature and high anti-interference
EFT/ESD, and the FTK touch function also has the performance of passing 10V-CS conductive interference,
which is suitable for application in various AC power products.
1. Touch
TM52FN8276/78:
1) Provide 19-ch capacitive touch, support internal reference capacitance and automatic touch clock modulation;
2) Using the FTK touch hardware method for touch detection, the touch detection speed is very fast, and the overall power consumption during detection is very small;
3) The highly integrated IC can provide up to 19 Touch key inputs without external capacitive components.
2. Other
peripherals

4. Development
toolsTenspeed has planned an easy-to-use USB development tool T-Link ICE Board for TM52FN8273/76/74/78 to connect
to EV Board, you can directly use the original IC (Real chip) for online debugging,
Connect the EV Board via USB to simulate the status of the IC in real time, directly access the memory and set the register,
provide breakpoints and step (STEP) for program debugging, and perform functions such as tracking and analyzing data.
Improve program development efficiency and debug capabilities, very suitable for rapid product development.
