EM78P45ISAQ

The EM78P45ISAQ is one kind of 8-bit microprocessor which designed and developed with low-power, high speed CMOS technology. It is very suitable for wired communication and is equipped with the Serial Peripheral Interface (SPI) function.

Features of the EM78P45ISAQ are:(1)operating voltage range:2.3V to 5.5V;(2)operating temperature range:0°C to 70°C;(3)low power consumption:less then 3 mA at 5V/4MHz and typically 10A during sleep mode;(4)serial peripheral interface (SPI) available;(5)4K * 13 bits on chip ROM;(6)11 special function registers;(7)140* 8 bits on chip general-purposed registers;(8)5 bi-directional I/O ports (35 I/O pins);(9)3 LED direct sinking pins with internal serial resist-ors;(10)built-in RC oscillator with external serial resistor, ±10% variation;(11)two machine clocks or four machine clocks per instruction cycle;(12)8-bit real time clock/counter (TCC) with overflow interrupt;(13)5 stacks for subroutine nesting;(14)built-in power-on reset.

The absolute maximum ratings of the EM78P45ISAQ can be summarized as:(1)temperature under bias:0°C to 70°C;(2)storage temperature:-65°C to 150°C;(3)input voltage:-0.3V to +6.0V;(4)output voltage:-0.3V to +6.0V;(5)operating frequency (2clk):DC to 20MHz.
