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 i n P IC12C671. These de vices hav e
EPROM ty pe m emory a nd ope rate o ver th e
standard voltage range.
2. LC, as in PIC1 2LC671. Th ese de vices h ave
EPROM ty pe m emory an d op erate over an
extended voltage range.
3. CE, as in PIC12 CE674. These de vices hav e
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 U V erasable v ersion, offered in windowed pack-
age, is optimal for prototype development and pilot pro-
grams.
The U V erasable v ersion ca n b e e rased and rep ro-
grammed to a ny o f t he configuration modes.
Microchip's PIC START Plu s an d PR O MATE pr o-
grammers b oth s upport t he 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 e rase t he p re-programmed i nternal
calibration value for the in ternal 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 w ho ne ed t he flexibility f or fre quent code
updates and small volume applications.
The OTP devices, packaged in plastic packages, per-
mit the user to program them once. In a ddition to th e
program m emory, the configuration bits m ust a lso b e
programmed.

2.3 Quick-Turn-Programming (QTP)
Devices
Microchip offers a Q TP 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 al l EPR OM locations an d co nfiguration opti ons
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 f ew user-defined lo cations in eac h de vice are p ro-
grammed with different serial numbers. The serial num-
bers may be random, pseudo-random, or sequential.
Serial prog ramming a llows e ach de vice to have a
unique n umber w hich c an serve as a n en try-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 a bove th e ph ysically implemented add ress w ill
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 7F h (128 bytes). The lower
locations of eac h Ban k are reserved for th e Spec ial
Function Registers. Above the Special Function Regis-
ters are Ge neral Purpose R egisters im plemented as
static RAM. Both Bank 0 and Bank 1 co ntain 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 in to Ba nk 0 registers 70h-7Fh as c ommon
RAM.
4.2.1 GENERAL PURPOSE REGISTER FILE
The register file can be accessed either directly or indi-
rectly thr ough the File Select R egister FSR
(Section 4.5).
