Time Delay relay

Arizona Microchip PIC16F722-I/SO is a mid-range PIC16 family 8-bit powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS flash based Microcontroller packs powerful PIC®(RISC) architecture. This product offers all of the advantages of the well recognized mid-range x14 architecture with standardized features including 3.5kB of addressable program memory size, 128bytes of data memory size, 25 general-purpose I/O pins and 11-channel 8-bit analog-to-digital (A/D) converter. This device operates at a maximum frequency of 20MHz with wide operating voltage of 1.8 to 5.5V.

Arizona Microchip PIC16F1827-I/P is a 8-bit 18-pin Flash Microcontroller with nanoWatt XLP technology. This family of device contains an enhanced mid-range 8-bit CPU core. The CPU has 49 instructions. Interrupt capability includes automatic context saving. The hardware stack is 16 levels deep and has overflow and underflow reset capability. The microcontroller with direct, indirect and relative addressing modes. Two file select registers (FSRs) provides the ability to read program and data memory. The enhanced mid-range core has a 15-bit program counter capable of addressing a 32k x 14 program memory space. Accessing a location above these boundaries will cause a wrap-around within the implemented memory space. The Reset vector is at 0000h and the interrupt vector is at 0004h.
