PIC16F676 Microcontroller IC

The PIC16F676 designed based on Microchip Technology. These are 8-bit, completely static, Flash-based CMOS microcontrollers that are low-cost and high-performance. With just 35 single-word/single-cycle instructions, these microcontrollers use a sophisticated RISC architecture. Except for programmed branching, which take two cycles, all instructions in this microcontroller run in a single cycle (200 s). The 14-pin PDIP, SOIC, and TSSOP packages are available for this microcontroller. The 10-bit Analog-to-Digital (A/D) converter has eight channels, a comparator, and 128 bytes of EEPROM data memory. This device may be used in a variety of fields, including automotive, industrial, appliances, and consumer entry-level products that require field reprogrammability.

 The PIC16F676 devices feature a 13-bit program counter capable of addressing an 8K x 14 program memory space. For the PIC16F676 devices, only the first 1K x 14 (0000h-03FFh) were physically implemented. As a result, accessing the location over these boundaries causes the initial 1K x 14 space to wrap around. The interrupt vector is at 0004h, whereas the reset vector is at 0000h. Meanwhile, the data memory was split into two banks, one containing the General Purpose Registers and the other containing the Special Function Registers. Each bank’s Special Function Registers are found in the first 32 places. The register positions 20h-5Fh, on the other hand, are dedicated to General Purpose Registers and are implemented as static RAM that is mapped across both banks. These registers are used by the Special Function Registers.
