General Description
The ET4003MTC 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 an infrared receiving and transmitting
circuit.
The ET4003MTC is best suited for applications such as ordinary remote or learning 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, adjustment error is less than + / 0.5%
Sleep mode current is about 1.0uA (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 Transistor for IR LED Drive
IOL = 220mA at VDD =3V & VO =0.3V and pwm_curt=1
