TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of your Microchip
products. To this end, we will continue to improve our publications to better suit your needs. Our publications will be refined and
enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications Department via
E-mail at [email protected] or fax the Reader Response Form in the back of this data sheet to (480) 792-4150. We
welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page.
The last character of the literature number is the version number, (e.g., DS30000A is version A of document DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current
devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision
of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site; http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature number) you are
using.

3.0 ARCHITECTURAL OVERVIEW
The high performance of the PIC12F529T48A device
can be attributed to a number of architectural features
commonly found in RISC microprocessors. To begin
with, the PIC12F529T48A device uses a Harvard
architecture in which program and data are accessed
on separate buses. This improves bandwidth over tra-
ditional 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 possi-
ble to have all single-word instructions. A 12-bit wide
program memory access bus fetches a 12-bit instruc-
tion in a single cycle. A two-stage pipeline overlaps
fetch and execution of instructions. Consequently, all
instructions (34) execute in a single cycle (500 ns @
8 MHz, 1 s @ 4 MHz) except for program branches.
Table 3-1 below lists memory supported by the
PIC12F529T48A device.

The PIC12F529T48A 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 PIC12F529T48A
device has a highly orthogonal (symmetrical) instruc-
tion set that makes it possible to carry out any opera-
tion, on any register, using any addressing mode. This
symmetrical nature and lack of “special optimal situa-
tions” make programming with the PIC12F529T48A
device simple, yet efficient. In addition, the learning
curve is reduced significantly.
The PIC12F529T48A 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.
PIC12F529T48A
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.
