Microchip Technology 12CE673
1.0 GENERAL DESCRIPTION
The PIC12CE67X devices are low-cost, high-perfor-
mance, CMOS, fully-static, 8-bit microcontroller with
integrated analog-to-digital (A/D) converter and
EEPROM data memory in the PIC12CEXXX Micro-
controller family.
All PICmicro™ microcontrollers employ an advanced
RISC architecture. The PIC12C67X microcontrollers
have enhanced core features, eight-level deep stack,
and multiple internal and external interrupt sources.
The separate instruction and data buses of the Harvard
architecture allow a 14-bit wide instruction word with
the separate 8-bit wide data. The two stage instruction
pipeline allows all instructions to execute in a single
cycle, except for program branches which require two
cycles. A total of 35 instructions (reduced instruction
set) are available. Additionally, a large register set gives
some of the architectural innovations used to achieve a
very high performance.
PIC12C67X microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC12CE67X devices have 128 bytes of RAM, 16
bytes of EEPROM data memory, 5 I/O pins and 1 input
pin. In addition a timer/counter is available. Also a 4-
channel high-speed 8-bit A/D is provided. The 8-bit res-
olution is ideally suited for applications requiring low-
cost analog interface, e.g. thermostat control, pressure
sensing, etc.
The PIC12CE67X device has special features to
reduce external components, thus reducing cost,
enhancing system reliability and reducing power con-
sumption. The Power-On Reset (POR), Power-up
Timer (PWRT), and Oscillator Start-up Timer (OST)
eliminate the need for external reset circuitry. There are
five oscillator configurations to choose from, including
INTRC precision internal oscillator mode and the
power-saving LP (Low Power) oscillator mode. Power
saving SLEEP mode, Watchdog Timer and code
protection features improve system cost, power and
reliability.The SLEEP (power-down) feature provides a
power saving mode. The user can wake up the chip
from SLEEP through several external and internal
interrupts and resets.
PIC12CE67X
A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software lock-
up.
A UV erasable windowed package version is ideal for
code development while the cost-effective One-Time-
Programmable (OTP) version is suitable for production
in any volume. The customer can take full advantage of
Microchip’s price leadership in OTP microcontrollers
while benefiting from the OTP’s flexibility.
The PIC12CE67X device fits perfectly in applications
ranging from security and remote sensors to appliance
control and automotive. The EPROM technology
makes customization of application programs (trans-
mitter codes, motor speeds, receiver frequencies, etc.)
extremely fast and convenient. The small footprint
packages make this microcontroller series perfect for
all applications with space limitations. Low cost, low
power, high performance, ease of use and I/O flexibility
make the PIC12CE67X very versatile even in areas
where no microcontroller use has been considered
before (e.g. timer functions, communications and
coprocessor applications).
1.1 Family and Upward Compatibility
The PIC12CE67X products are compatible with other
members of the 14-Bit, PIC12C67X and PIC16CXXX
families.
1.2 Development Support
The PIC12CE67X device is supported by a full-fea-
tured macro assembler, a software simulator, an in-cir-
cuit emulator, a low-cost development programmer and
a full-featured programmer. A “C” compiler and fuzzy
logic support tools are also available.
