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.
