TM52F5274/F5278 integrates high efficiency F51 internal core, with accurate
12-bit resolution ADC, low power consumption real time clock and LCD/LED
display function, TM52F5274 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 TM52F5278 also has touch key
function, can be applied in products such as: LCD 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.
TM52F5274/F5278 uses tenx F51 CPU Core, compared to the traditional 8051
IC, the overall operating speed is faster and more efficient. TM52F5274/F5278
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, and internal XRAM 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.
TM52F5274/F5278 provides very varied LCD display architecture, the driving
capability is up to 4 COM * 18 SEG selectable LCD pixel, 1/3 and 1/4 duty,
provides 1/3 Bias potential and supports 8 brightness selection. Besides, it also
supports LED transductive output, LED can support up to 4 COM * 18 SEG pixel
output, each COM pin output capability is 40 mA in external output control. In
internal TM52F5274/F5278 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.
TM52F5274/F5278 provides 2 sets of 8+2 PWM digital output, while external
input provides 10-ch input 12-bit ADC. Besides, TM52F5278 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, TM52F5278 touch key structure is
highly-integrated IC, only needs very little external element, yet can provide up
to 14 touch key inputs.
For TM52F5274/F5278, tenx plans of using convenient USB development tool
T-Link ICE Board connection EV5278 board, which can directly use the original
IC (Real chip) to do ICE in-line trimming. Using USB EV5278 Board immediately
simulate IC condition, can access memory space and set register directly,
provide routine breakpoint and step, can execute tracking analysis data,
ncrease program development efficiency and debug capability, very suitable for
fast product development. Packaging with 28/32 SOP/DIP provide the best
possible package pin.
