Overview

The on-chip Flash is composed by two matrix modules each one containing one array

divided in two banks that can be read and modified independently one of the other: one

bank can be read while another bank is under modification.

I-BUS interface

X-BUS interface

The write operations of the 4 banks are managed by an embedded Flash program/erase

controller (FPEC). The high voltages needed for program/erase operations are internally

generated.

The data bus is 32-bit wide. Due to ST10 core architecture limitation, only the first

512 Kbytes are accessed at 32-bit (internal Flash bus, see I-BUS), while the remaining

320 Kbytes are accessed at 16-bit (see X-BUS).
