DescriptionThe PIC16F873A-I/SO is one member of the PIC16F873 family which is designed as the 28/40-pin, enhanced flash-based 8-bit CMOS microcontroller. This device has a 13-bit program counter capable of addressing a 8K x 14 (0000h-1FFFh) for the program memory space. The Reset vector is at 0000h and the interrupt vector is at 0004h.
Features of the PIC16F873A-I/SO are:(1)All single-cycle instructions except branches;(2)Interrupt capability;(3)8-level deep hardware stack;(4)Direct, Indirect and Relative Addressing modes;(5)Power-Saving Sleep mode;(6)Wide operating voltage range (2.0 V-5.5 V);(7)Industrial and Extended Temperature range;(8)Power-on Reset (POR);(9)Power-up Timer (PWRT) and Oscillator Start-up Timer (OST);(10)Brown-out Reset (BOR) with software control option.
The absolute maximum ratings of the PIC16F873A-I/SO can be summarized as:(1)Ambient temperature under bias: -40°C to +125°C;(2)Storage temperature: -65°C to +150°C;(3)Voltage on VDD with respect to VSS: -0.3 V to +6.5 V;(4)Voltage on MCLR with respect to Vss: -0.3 V to +13.5 V;(5)Voltage on all other pins with respect to VSS: -0.3 V to (VDD + 0.3 V);(6)Total power dissipation: 800 mW;(7)Maximum current out of VSS pin: 300 mA;(8)Maximum current into VDD pin: 250 mA;(9)Input clamp current, IIK (VI < 0 or VI > VDD): +/- 20 mA;(10)Output clamp current, IOK (Vo < 0 or Vo >VDD): +/- 20 mA.
