TM52M8264/M8268 integrates high efficiency F51 internal core, with accurate 12-
bit resolution ADC, low power consumption real time clock function, TM52M8264 is
very suitable for home appliances, for example rice cooker, coffee maker, electric
stove, thermos, battery chargers, hood, etc… AC home appliances, while
TM52M8268 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, suitable for use in a variety of AC
power supply product field.
TM52M8264/M8268 uses tenx F51 CPU Core, compared to the traditional 8051
IC, the overall operating speed is faster and more efficient. TM52M8264/M8268
keeps most of the characteristics in standard 8051, program memory provides 8 K
Bytes MTP memory space; developers can store data directly into MTP memory
space, while internal IRAM provides 512 Bytes storage space, UART interface is
compatible with standard 8051, 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 TM52M8264/M8268 provides dual frequency input FRC 14.7456 MHz
or SRC 68 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.
TM52M8264/M8268 provides 2 sets of 8+2 PWM digital output, while external
input provides 10-ch input 12-bit ADC and internal VBG. Besides, TM52M8268
provides 15-ch capacitive touch, 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, TM52M8268 touch key structure is highly-integrated IC,
only needs very little external element, yet can provide up to 15 touch key inputs.
For TM52M8264/M8268, 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 TSSOP20, 20/24-SOP/DIP, MSOP10,QFN20 provide
the best possible package pin.
