ARCHITECTURAL OVERVIEW
The high performance of the PIC12F519 device can
be attributed to a number of architectural features
commonly found in RISC microprocessors. To begin
with, the PIC12F519 device uses a Harvard architec-
ture in which program and data are accessed on sep-
arate 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 instruc-
tions (33) execute in a single cycle (500 ns @ 8 MHz,
1
μs @ 4 MHz) except for program branches.
Table 3-1 below lists memory supported by the
PIC12F519 device.
TABLE 3-1:
PIC12F519 MEMORY
The PIC12F519 device 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 PIC12F519 device
has a highly orthogonal (symmetrical) instruction set
that makes it possible to carry out any operation, on
any register, using any addressing mode. This symmet-
rical nature and lack of “special optimal situations”
make programming with the PIC12F519 device simple,
yet efficient. In addition, the learning curve is reduced
significantly.
The PIC12F519 device contains an 8-bit ALU and
working register. The ALU is a general purpose arith-
metic unit. It performs arithmetic and Boolean functions
between data in the working register and any register
file.
The ALU is 8 bits wide and capable of addition,
subtraction, shift and logical operations. Unless other-
wise 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.
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, respec-
tively, in subtraction. See the SUBWF and ADDWF
instructions for examples.
A simplified block diagram is shown in Figure 3-1, with
the corresponding device pins described in Table 3-2.
