2.0 PIC12C67X DEVICE VARIETIES
A variety of frequency ranges and packaging options
are available. Depending on application and production
requirements, the proper device option can be selected
using the information in the PIC12C67X Product Iden-
tification System section at the end of this data sheet.
When placing orders, please use that page of the data
sheet to specify the correct part number.
For example, the PIC12C67X device “type” is indicated
in the device number:
1. C, as in PIC12C671. These devices have
EPROM type memory and operate over the
standard voltage range.
2. LC, as in PIC12LC671. These devices have
EPROM type memory and operate over an
extended voltage range.
3. CE, as in PIC12CE674. These devices have
EPROM type memory, EEPROM data memory
and operate over the standard voltage range.
4. LCE, as in PIC12LCE674. These devices have
EPROM type memory, EEPROM data memory
and operate over an extended voltage range.
2.1 UV Erasable Devices
The UV erasable version, offered in windowed pack-
age, is optimal for prototype development and pilot pro-
grams.
The UV erasable version can be erased and repro-
grammed to any of the configuration modes.
Microchip's PICSTART® Plus and PRO MATE® pro-
grammers both support the PIC12C67X. Third party
programmers also are available; refer to the Microchip
Third Party Guide for a list of sources.
Note:
Please note that erasing the device will
also erase the pre-programmed internal
calibration value for the internal oscillator.
The calibration value must be saved prior
to erasing the part.
2.2 One-Time-Programmable (OTP)
Devices
The availability of OTP devices is especially useful for
customers who need the flexibility for frequent code
updates and small volume applications.
The OTP devices, packaged in plastic packages, per-
mit the user to program them once. In addition to the
program memory, the configuration bits must also be
programmed.

2.3 Quick-Turn-Programming (QTP)
Devices
Microchip offers a QTP Programming Service for fac-
tory production orders. This service is made available
for users who choose not to program a medium to high
quantity of units and whose code patterns have stabi-
lized. The devices are identical to the OTP devices, but
with all EPROM locations and configuration options
already programmed by the factory. Certain code and
prototype verification procedures apply before produc-
tion shipments are available. Please contact your local
Microchip Technology sales office for more details.
2.4 Serialized Quick-Turn Programming
(SQTPSM) Devices
Microchip offers a unique programming service where
a few user-defined locations in each device are pro-
grammed with different serial numbers. The serial num-
bers may be random, pseudo-random, or sequential.
Serial programming allows each device to have a
unique number which can serve as an entry-code,
password, or ID number.

4.0 MEMORY ORGANIZATION
4.1 Program Memory Organization
The PIC12C67X has a 13-bit program counter capable
of addressing an 8K x 14 program memory space.
For the PIC12C671 and the PIC12CE673, the first 1K x
14 (0000h-03FFh) is implemented.
For the PIC12C672 and the PIC12CE674, the first 2K
x 14 (0000h-07FFh) is implemented. Accessing a loca-
tion above the physically implemented address will
cause a wraparound. The reset vector is at 0000h and
the interrupt vector is at 0004h.

4.2 Data Memory Organization
The data memory is partitioned into two banks, which
contain the General Purpose Registers and the Special
Function Registers. Bit RP0 is the bank select bit.
RP0 (STATUS<5>) = 1 Bank 1
RP0 (STATUS<5>) = 0 Bank 0
Each Bank extends up to 7Fh (128 bytes). The lower
locations of each Bank are reserved for the Special
Function Registers. Above the Special Function Regis-
ters are General Purpose Registers implemented as
static RAM. Both Bank 0 and Bank 1 contain Special
Function Registers. Some "high use" Special Function
Registers from Bank 0 are mirrored in Bank 1 for code
reduction and quicker access.
Also note that F0h through FFh on the PIC12C67X is
mapped into Bank 0 registers 70h-7Fh as common
RAM.
4.2.1 GENERAL PURPOSE REGISTER FILE
The register file can be accessed either directly or indi-
rectly through the File Select Register FSR
(Section 4.5).
