tenx launched a new TM52F5264 / F5268 high efficiency type F51 series
2015/01/05
    TM52F5264/F5268 integrates high efficiency F51 internal core, with accurate 12-bit 
resolution ADC, low power consumption real time clock function, TM52F5264 is very 
suitable for home appliances, for example   rice cooker, coffee maker, electric stove, 
thermos, battery chargers, hood, etc… AC home appliances, while TM52F5268 also has 
touch key function, can be applied in products such as: Touch key rice cooker, Touch 
key electric stove, Touch key coffee maker, touch key thermos, touch key hood , touch 
key control home appliances, etc….The specification meets engineering rules -40℃
~85℃ operating temperature and high noise immunity EFT/ESD characteristics demand, 
through 10Vrms for Conducted Susceptibility (CS) test in touch, suitable for use in a 
variety of AC power supply product field.

    TM52F5264/F5268 uses tenx F51 CPU Core, compared to the traditional 8051 IC, the 
overall operating speed is faster and more efficient. TM52F5264/F5268 keeps most of 
the characteristics in standard 8051, program memory provides 8 K Bytes flash 
memory space, and also provides ICP/ISP/IAP storage function; developers can store 
data directly into Flash memory space, while internal IRAM provides 256 Bytes storage 
space, UART interface is compatible with standard 8051, and provides one set of SPI 
interface, Timer0/1/2 is standard 8051 timer. Besides, in Timer3 user can use 32.768 
KHz clock source. Timer3 provides 15-bit timer which allows time counting, provides 
developer very accurate clock source.

    In internal TM52F5264/F5268 provides dual frequency input FRC 7.3728 MHz or SRC 
24 KHz, while external also provides dual frequency input FXT 1~8 MHz and SXT 32.768 
KHz. And allows developer chooses system frequency, can select different operating 
frequency under different operating mode (Fast/Slow/Idle/Stop); can achieve the 
overall power saving.

    TM52F5264/F5268 provides 2 sets of 8+2 PWM digital output, while external input 
provides 10-ch input 12-bit ADC. Besides, TM52F5268 provides 14-ch capacitive touch 
(TK0~TK13), while providing very low power of ATK (TK0~TK3) Touch key interrupt 
structure, using touch key hardware for touch key detection. Therefore, touch key 
detection speed is very fast, the overall power consumption is very small when 
detected, TM52F5268 touch key structure is highly-integrated IC, only needs very little 
external element, yet can provide up to 14 touch key inputs.

    For TM52F5264/F5268, tenx plans of using convenient USB development tool T-Link 
ICE Board connection EV5268 board, which can directly use the original IC (Real chip) 
to do ICE in-line trimming. Using USB EV5268 Board immediately simulate IC condition, 
can access memory space and set register directly, provide routine breakpoint and 
step, can execute tracking analysis data, increase program development efficiency and 
debug capability, very suitable for fast product development. Packaging with 20/24 
SOP/DIP provide the best possible package pin.
