Internal Flash memory
Overview
The on-chip Flash is composed of two matrix modules, each one containing one array
divided in two banks that can be read and modified independently of one another: one bank
can be read while another bank is under modification.
Figure 4.
The write operations of the four 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).
