pin in order to start EPROM programming. A signal

applied to PB1 is used to increment the memory

address; the data is supplied to PORT A (see

EPROM programming for further details).

The processor starts the working phase following

the instructions, which have been previously

loaded in the memory.

ST52x430’s internal structure includes a

computational block, CONTROL UNIT (CU) /

DATA PROCESSING UNIT (DPU), which allows

processing of boolean functions and fuzzy

algorithms.

The CU/DPU can manage up to 334 different

Membership Functions for the fuzzy rules

antecedent part. The rule consequents are “crisp”

values (real numbers). The maximum number of

rules that can be defined is limited by the

dimensions of the implemented standard

algorithm.

EPROM is then shared between fuzzy and

standard algorithms. The Membership Function

data is stored inside the first 1024 memory

locations. The Fuzzy rules are parts of the program

instructions.

The Control Unit (CU) reads the information and

the status deriving from the peripherals.

Arithmetic calculus can be performed on these

values by using the internal CU and the 128/256

bytes of RAM, which supports all computations.

The peripheral input can be fuzzy and/or arithmetic

output, or the values contained in Data RAM and

EPROM locations.
