Ever wish you had just a handful of extra input/output
(I/O) pins available Your wish has just come true! If
your application requires a few more pins than those
available in the 56F8346, the 56F8347 is the device
for you. With its 156 KB of on-chip Flash memory, the
56F8347 has the same memory footprint as the
56F8346, yet provides an additional 14 digital I/O pins
with its 160-pin LQFP package. You will continue to
benefit from the use of pulse width modulation
(PWM) outputs, analog-to-digital converter (ADC)
inputs and timer channels, along with the ability to
interface with other devices in your system via the
external memory interface. When you need the right
mix of functionality without adding memory, the
56F8345, 56F8346 and 56F8347 are the ideal devices
for you.

BENEFITS
Hybrid architecture facilitates
implementation of both control
and signal processing functions in
a single device
High-performance, secured Flash
memory helps eliminate the need for
external storage devices
Extended temperature range allows for
operation of nonvolatile memory in
harsh environments
Flash memory emulation of EEPROM
helps eliminate the need for external
nonvolatile memory
32-bit performance with 16-bit
code density
On-chip voltage regulator and power
management help reduce overall
system cost
Off-chip memory expansion capabilities
allow for glueless interfacing with the
additional memory of external devices
without sacrificing performance
This device boots directly from
Flash, providing additional
application flexibility
High-performance PWM with
programmable fault capability simplifies
design and promotes compliance with
safety regulations
PWM and ADC modules are tightly
coupled to help reduce processing
overhead
Low-voltage interrupts (LVIs) help
protect the system from brownout
or power failure
General-purpose input/output (GPIO)
pins support application-specific needs
Simple in-application Flash memory
programming via Enhanced
On-Chip Emulation (EOnCE) or
serial communication
