1.1.5
1.2 Device Description
The 56F8323 and 56F8123 are members of the 56800E core-based family of controllers. Each combines,
on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a
microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because
of their low cost, configuration flexibility, and compact program code, the 56F8323 and 56F8123 are
well-suited for many applications. The devices include many peripherals that are especially useful for
automotive control (56F8323 only); industrial control and networking; motion control; home appliances;
general purpose inverters; smart sensors; fire and security systems; power management; and medical
monitoring applications.
The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in
parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model
and optimized instruction set allow straightforward generation of efficient, compact DSP and control
code. The instruction set is also highly efficient for C Compilers to enable rapid development of
optimized control applications.
The 56F8323 and 56F8123 support program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. These devices also provide one external
dedicated interrupt line and up to 27 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
1.2.1
The 56F8323 controller includes 32KB of Program Flash and 8KB of Data Flash, each programmable
through the JTAG port, with 4KB of Program RAM and 8KB of Data RAM. A total of 8KB of Boot Flash
is incorporated for easy customer inclusion of field-programmable software routines that can be used to
program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be
independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash
page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8323 is the inclusion of one Pulse Width Modulator (PWM)
module. This module incorporates three complementary, individually programmable PWM signal output
pairs and is also capable of supporting six independent PWM functions to enhance motor control
functionality. Complementary operation permits programmable dead time insertion, distortion correction
via current sensing by software, and separate top and bottom output polarity control. The up-counter value
is programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned
