The high performance of the PIC16LF505 devices can be attributed to a number of architectural features commonly found in RISC microprocessors after Retrieve PIC MCU.

The PIC12F510/16F506 devices use a Harvard architecture in which program and data are accessed on separate buses. This improves bandwidth over traditional von Neumann architectures where program and data are fetched on the same bus. Separating program and data memory further allows instructions to be sized differently than the 8-bit wide data word. Instruction opcodes are 12 bits wide, making it possible to have all single-word instructions. A 12-bit wide program memory access bus fetches a 12-bit instruction in a single cycle. A two-stage pipeline overlaps fetch and execution of instructions. Consequently, all instructions (33) execute in a single cycle (200 ns @ 20 MHz, 1 ìs @4 MHz) except for program branches when Retrieve PIC MCU.

Table 3-1 lists program memory (Flash) and data memory (RAM) for the PIC12F510/16F506 devices.

The PIC12F510/16F506 devices can directly or indirectly address its register files and data memory. All Special Function Registers (SFR), including the PC, are mapped in the data memory. The PIC16lF505 devices have a highly orthogonal (symmetrical) instruction set that makes it possible to carry out any operation, on any register, using any addressing mode. This symmetrical nature and lack of “special optimal situations” make programming with the PIC16LF505 devices simple, yet efficient. In addition, the learning curve is reduced significantly if Retrieve PIC MCU.

The PIC16LF505 devices contain an 8-bit ALU and working register. The ALU is a general purpose arithmetic unit. It performs arithmetic and Boolean functions between data in the working register and any register file. 4 MHz) except for program branches when Retrieve PIC MCU.

Table 3-1 lists program memory (Flash) and data memory (RAM) for the PIC12F510/16F506 devices.

The ALU is 8 bits wide and capable of addition, subtraction, shift and logical operations. Unless otherwise mentioned, arithmetic operations are two’s complement in nature. In two-operand instructions, one operand is typically the W (working) register. The other operand is either a file register or an immediate constant. In single-operand instructions, the operand is either the W register or a file register for the purpose of Retrieve PIC MCU.

The W register is an 8-bit working register used for ALU operations. It is not an addressable register. Depending on the instruction executed, the ALU may affect the values of the Carry (C), Digit Carry (DC) and Zero (Z) bits in the STATUS register. The C and DC bits operate as a borrow and digit borrow out bit, respectively, in subtraction. See the SUBWF and ADDWF instructions for examples for Retrieve PIC MCU.
