Specification :

EM78P447 microcontroller EM78P447 is YiLong company USES high-speed Taiwan CMOS process manufacturing 8-bit microcontroller, its internal sets have 13bitOTP 4096 x (one-time) ROM (program memory), the user through simulators writing, and testing the correct opcode files by EMC programmer burn into seven bits, chip OPTION structure selector (CODE) to meet user requirements. Among them 1 bit for encryption bits, can prevent program is read. Main feature working voltage: 2.3-5.5 V working temperature: 0-70 ¡æ clock frequency: DC - 18MHz low power consumption: in 5V / 4MHz working conditions, the current 3V / 2.2 mA, less than 32kHz conditions, the current 30uA, sleep patterns for 1uA. Under current only for 4096 x 13bit program memory (OTPROM), 148 x 8 slices of RAM (SDRAM) within.
