tenx launched a new TM52FN8273/ 76 /74 / 78 high efficiency type TM52series
    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
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 
TM52FN8273/76/74/78 retain most of the standard 8051 features.
TM52FN8273/76/74/78 provides dual frequency input fast clock FRC 14.7456MHz or slow clock SRC 80 KHz,
External dual frequency input FXT 1~16 MHz and SXT32.768 KHz are also provided, 
and the system frequency is selected by the developer.
Different working frequencies can be selected in different working modes (Fast/Slow/Idle/Stop) to achieve overall power saving.
16K Bytesflash memory space provided by TM52FE8273/76 program memory, 8K Bytesflash memory space provided by TM52FE8274/78 program memory,
And provide ICP/ISP/IAP storage function, 
developers can also directly store data in EEPROM 128Bytes memory.
In the memory memory IRAM provides 256 Bytes storage space, and the memory memory XRAM provides 768Bytes storage space, 
a set of UART interface is compatible with standard 8051,
And provides 1 set of SPI interface, Timer0/1/2 is standard 8051 timer, and Timer3 can use external 32.768KHz oscillator,
And provides a 15-bit timer for time counting, providing developers with a very accurate clock source. In addition, TM52FN8273/76/74/78 provides 3 groups of 8+2 PWM digital outputs,
The external input provides a precise 12-bit 14-ch input AD converter, as well as the internal reference voltage VBG, and 4 kinds of ADC internal reference voltage sources: 2.5V/ VCC.

3. Application
TM52FN8273/76/74/78 can be applied to AC home appliances such as rice cookers, 
coffee pots, thermos, chargers, range hoods, etc. with LCD/LED display.
TM52FN8276/78 also has FTK touch function, 
which can be applied to touch electric appliances such as touch rice cookers, touch induction cookers, 
touch thermos, touch range hoods, and touch coffee machines.

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.
