tenx launched a new TM52F8276/F8273 high efficiency type F51 series
    TM52F8276/F8273 integrates high efficiency F51 internal core, with accurate 12-
bit resolution ADC, low power consumption real time clock and LCD/LED display 
function, TM52F8276/F8273 is very suitable for home appliances, for example 
LCD/LED display rice cooker, coffee maker, electric stove,  thermos, battery 
chargers, hood, etc… AC home appliances, while TM52F8276 also has touch key 
function, can be applied in products such as: LCD/LED display touch key rice cooker, 
touch key electric stove, touch key coffer 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.

    TM52F8276/F8273 uses tenx F51 CPU Core, compared to the traditional 8051 IC, 
the overall operating speed is faster and more efficient. TM52F8276/F8273 keeps 
most of the characteristics in standard 8051, program memory provides 16K Bytes 
flash memory space, and also provides ICP/ISP/IAP storage function; developers 
can store data directly into EEPROM 128Bytes memory space, while internal IRAM 
provides 256 Bytes storage space, and internal XRAM provides 768 Bytes storage 
space, Provide 2 sets of UART interfaces 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.

    TM52F8276/F8273 provides very varied LCD display architecture, the driving 
capability is up to 8 COM 1/2 Bias, it also supports LED transductive output, LED can 
support up to 4 COM * 6 SEG pixel max. 48 dots output. In internal 
TM52F8276/F8273 provides dual frequency input FRC 12.9024 MHz or SRC 68 KHz, 
while external also provides dual frequency input FXT 1~12 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.

    TM52F8276/F8273 provides 3 sets of 8+2 PWM digital output, while external input 
provides 14-ch input 12-bit ADC and internal VBG. Besides, TM52F8276 provides 16-
ch capacitive touch key, 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, TM52F8276 touch key structure is highly-integrated IC, 
only needs very little external element, yet can provide up to 16 touch key inputs.

    For TM52F8276/F8273, tenx plans of using convenient USB development tool T-Link 
ICE Board connection EV8276 board, which can directly use the original IC (Real 
chip) to do ICE in-line trimming. Using USB EV8276 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 QFN20/24/28, TSSOP20,SSOP28,SOP20/24/28 and 
DIP20 provide the best possible package pin.
