Specification :

1, the more low cost OTP type or goes directly alternative PIC16CXX type, tube feet all compatible, software convertible, corresponding relations EM78P153 - PIC12C508, EM78P156: PIC16C54/56, EM78P447 - - PIC12C55/57. 2, 11 ~ 35 two-way I/O port (10mA input/output, with programmable pull up and down resistance), has the TCC timed interruption, external interruption, I/O change interrupt sensei SLEEP. 3, a watchdog, since run type low voltage detection reset circuit, and the program confidential bits. 4, EM78P153 containing RC oscillation, avoid external oscillators, smaller, more cost-effective. 5, faster instruction cycle: RC (maximum 8MHZ), XT (ceramic or crystals, 0 ~ 36MHZ) oscillation programming choose the 13th word length single-byte single cycle instructions, 0.1 us / 20MHZ. 6 and lower power consumption: 32KHZ 3V: 15uA, SLEEP / : 1uA. 7, EM78P153 for 14pin encapsulation, have: DIP - 14, SOP - 14 and SSOP - 14 three encapsulation.
