Internal Flash memory

Doc ID 12303 Rev 3

Internal Flash memory

4.1

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.

Flash modules structure

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).
