General Description The ET4002MC/MTC is a high performance, low cost CMOS 8bit single chip microcontroller with an embedded 8K*16bit OTPROM,a high precision 5MHz oscillator, 13 general IO or 13 key scan IO and transmitting circuit(For ET4002MTC). The ET4002MC/MTC is best suited for applications such as ordinary remote controller, general IO application controller etc.
Features
8bit microcontroller,53 single word instructions Embedded 8K*16 bit program memory, 512byte data memory Program memory can be configured as 4k*16 bit MTP and program twice CPU operation voltage rang is from 2.0V to 3.6V Embedded 5MHz oscillator, and the frequency can be finetuning When the work voltage range is from 2.0v to 3.6v, and the temperature range is from 20°to 85°,the CPU frequency error is less than +/ 1% Sleep mode current is less than 1.0µA(when key scan is disable), and is about 1.0µA(when key scan is enable) 8level hardware stacks 15 Interrupt sources(internal:2 Timer,external:13 Input port) All 13 I/O can be configured as General Purpose I/O or keyboard scan IO Support Ttype keyboard and the key code can be read by hardware Embedded Timer A(include PWM generator)and Timer B 3 programmable PWM output port(the two PWM output port is sharing by two general IO port) Key wakeup, Mtype or Ttype key change wakeup from SLEEP mode Built in
