1.0
The PIC16C432 is a 20-pin EPROM-based member of
the versatile PICmicro
mance, CMOS, fully-static, 8-bit microcontrollers with
an integrated LIN transceiver.
The LIN physical layer is implemented in hardware with
a voltage range from 0V to 18V, with a 40V transient
capability. The LIN protocol is to be implemented in
firmware, which enables flexibility with future revisions
of the LIN protocol.
All PICmicro
RISC architecture. The PIC16C432 device has
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
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.
PIC16C432 microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC16C432 has 12 I/O pins and an 8-bit timer/
counter with an 8-bit programmable prescaler. In addi-
tion, the PIC16C432 adds two analog comparators with
a programmable on-chip voltage reference module.
The comparator module is ideally suited for applica-
tions requiring a low cost analog interface (e.g., battery
chargers,
controllers, etc.).
PIC16C432 devices have special features to reduce
external components, thus reducing system cost,
enhancing system reliability and reducing power con-
sumption. There are four oscillator options, of which the
single pin RC oscillator provides a low cost solution, the
LP oscillator minimizes power consumption, XT is a
standard crystal, and the HS is for High Speed crystals.
The SLEEP (power-down) mode offers power savings.
The user can wake-up the chip from SLEEP through
several external and internal interrupts and RESET.

Preliminary
A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software lock-
up.
A UV erasable CERDIP packaged version is ideal for
code development, while the cost effective One-Time-
Programmable (OTP) version is suitable for production
in any volume.
A simplified block diagram of the PIC16C432 is shown
in Figure 4-1.
The PIC16C432 series fits perfectly in automotive and
industrial applications, which require LIN as a commu-
nication platform. The EPROM technology makes
customization of application programs (detection
levels, pulse generation, timers, 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 per-
formance, ease of use and I/O flexibility make the
PIC16C432 very versatile.
1.1
The PIC16C432 family is supported by a full-featured
macro assembler, a software simulator, an in-circuit
emulator, a low cost development programmer and a
full-featured programmer. A “C” compiler is also
available.
