PIC16F62X
2.0
ARCHITECTURAL OVERVIEW
The high performance of the PIC16F62X family can be
attributed to a number of architectural features
commonly found in RISC microprocessors. To begin
with, the PIC16F62X uses a Harvard architecture, in
which, program and data are accessed from separate
memories using separate buses. This improves
bandwidth over traditional Von Neumann architecture
where program and data are fetched from the same
memory. Separating program and data memory further
allows instructions to be sized differently than 8-bit
wide data word. Instruction opcodes are 14-bits wide
making it possible to have all single-word instructions.
A 14-bit wide program memory access bus fetches a
14-bit instruction in a single cycle. A two-stage pipeline
overlaps
fetch
and
execution
of
instructions.
Consequently, all instructions (35) execute in a single
cycle
(200 ns
@
20 MHz)
except
for
program
branches.
The Table below lists program memory (FLASH, Data
and EEPROM).
TABLE 2-1:
DEVICE DESCRIPTION
The PIC16F62X can directly or indirectly address its
register files or data memory. All Special Function
registers, including the program counter, are mapped in
the data memory. The PIC16F62X have an 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
PIC16F62X simple yet efficient. In addition, the learning
curve is reduced significantly.
The PIC16F62X 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.
The ALU is 8-bit 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,
typically
one
operand
is
the
working
register
(W register). The other operand is 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,
respectively, bit in subtraction. See the SUBLW and
SUBWF
instructions for examples.
A simplified block diagram is shown in Figure 2-1, and
a description of the device pins in Table 2-1.
Two types of data memory are provided on the
PIC16F62X
devices.
Non-volatile
EEPROM
data
memory is provided for long term storage of data such
as calibration values, lookup table data, and any other
data which may require periodic updating in the field.
This data is not lost when power is removed. The other
data memory provided is regular RAM data memory.
Regular RAM data memory is provided for temporary
storage of data during normal operation. It is lost when
power is removed.
