3 EPROM
EPROM memory provides an on-chip user-
programmable non-volatile memory, which allows
fast and reliable storage of user data.
EPROM memory can be locked by the user. In
fact, a memory location called Lock Cell is devoted
to lock EPROM and avoid external operations. A
software identification code, called ID CODE,
distinguishes which software version is stored in
the memory.
32 kbits of memory space with an 8-bit internal
parallelism (up to 4 kbytes) addressed by a 12-bit
bus are available. The data bus is 8 bits.
Memory has a double supply: V
PP
is equal to
12V
±
5% in Programming Phase or to V
SS
during
Working Phase. V
DD
is equal to 5V
±
10%.
ST52T410/ST52x420 EPROM memory is divided
into three main blocks (see Figure ):
I
Interrupt Vectors memory block
(3 through 17)
contains the addresses for the interrupt routines.
Each address is composed of three bytes.
Figure 3.1 Program Memory Organization
I
Mbfs Setting memory block
(18 through
MemAdd
) contains the coordinates of the
vertexes of every Mbf defined in the program.
I
The maximum value of MemAdd is 1023. This
area is dynamically assigned according to the
size of the fuzzy routines. The unused memory
area, if any, is assigned to the Program
Instruction Set memory block.
I
The Program Instructions Set memory block
(MemAdd through 4095) contains the instruction
set of the user program.
Locations 0, 1 and 2 contain the address of the first
microcode instruction.The operations that can be
performed on EPROM during the Programming
Phase are: Stand By, Memory Writing, Reading
and Verify/Margin Mode, Memory Lock, IDCode
Writing and Verify.
