AR2001

The AR2001 is a single chip intergrated processor with peripherals suitable for portable and/or embedded control and computation application.There are some functions and capabilities as follows.First is 32-bit processor with seperate instruction and data cache.The second is 6 device decoder with programmable base,offset and access wait state select.Then is 1 dedicated and 6 shared general purpose I/O ports.Next is support for 32- and 16-bit SDRM device interface and 2 SDRM banks.The fifth is interrupt controller with 8 external interrupt inputs with flexible request to CPU IRQ mapping.The sixth is 316-bit programmable timers.The seventh is real time clock with alarm,stop-watch timer and watch dog timer.The eighth is ADC with touch-screen controller.The last one is crystal oscillator and clock generator PLL.

What comes next is about the absolute maximum ratings of AR2001.The T_OP (operating temperature) is from 0 to 80.The T_STG (storage temperature) is from -40 to 125.The V_DD33 (I/O supply voltage) is from -0.3 to 4.3 V.The V_DD26 (core supply voltage) is from -0.3 to 3.25 V.The V_IN (input voltage) is from -0.3 to V_DD+0.3 V.

The following is about the DC characteristics of AR2001(T_OP=0 to 70,V_DD=3.3 V±0.3 V,V_SS=0 V).The minimum V_IL (input low voltage) is -0.3 V and the maximum is 0.8 V.The minimum V_IH (input high voltage) is 2.0 V and the maximum is V_DD+0.3 V.The maximum V_OL (output low voltage) is 0.4 V.The minimum V_OH (output high voltage) is 2.4 V.The minimum I_LI (input leakage current) and I_LO (output leakage current) are both 0A.The minimum C_IN,C_OUT (input capacitance and output capacitance) is 3 pF and the maximum is 8 pF.
