1.2 56F826 Description
The 56F826 is a member of the 56800 core-based family of processors. It combines, on a single chip, the
processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to
create an extremely cost-effective solution for general purpose applications. Because of its low cost,
configuration flexibility, and compact program code, the 56F826 is well-suited for many applications.
The 56F826 includes many peripherals that are especially useful for applications such as: noise
suppression, ID tag readers, sonic/subsonic detectors, security access devices, remote metering, sonic
alarms, POS terminals, feature phones.
The 56800 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 microprocessor-style programming
model and optimized instruction set allow straightforward generation of efficient, compact code for both
DSP and MCU applications. The instruction set is also highly efficient for C/C++ Compilers to enable
rapid development of optimized control applications.
The 56F826 supports program execution from either internal or external memories. Two data operands can
be accessed from the on-chip Data RAM per instruction cycle. The 56F826 also provides two external
dedicated interrupt lines, and up to 46 General Purpose Input/Output (GPIO) lines, depending on
peripheral configuration.
The 56F826 controller includes 31.5K words (16-bit) of Program Flash and 2K words of Data Flash (each
programmable through the JTAG port) with 512 words of Program RAM, and 4K words of Data RAM. It
also supports program execution from external memory.
The 56F826 incorporates a total of 2K words of Boot Flash 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 page
sizes of 256 words. The Boot Flash memory can also be either bulk- or page-erased.
