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.
64 kbits of memory space with an 8-bit internal
parallelism (up to 8 kbytes) addressed by an 13-bit
bus are available. The data bus is 8 bits.
Memory has a double supply: VPP is equal to
12V
±5% in Programming Phase or to VSS during
Working Phase. VDD is equal to 5V±10%.
ST52x430 EPROM memory is divided into three
main blocks (see Figure ):
I Interrupt Vectors memory block (3 through 20)
contains the addresses for the interrupt routines.
Each address is composed of three bytes.
I Mbfs Setting memory block (21 through
MemAdd) contains the coordinates of the
vertexes of every Mbf defined in the program.
Figure 3.1 Program Memory Organization
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 MemAddx) contains the
instruction set of the user program. The
following table summarizes the values of Mem
Addx for the different devices
Table 3.1 Mem Addx
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.
