26 / 189 page  Internal Flash memory ST10F272Z2 26/189 5 Internal Flash memory 5.1 Overview The on-chip Flash is composed by one matrix module, 256 KBytes wide. This module is on ST10 Internal bus, so it is called IFLASH Figure 5. Flash structure The programming operations of the flash 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 for fetch accesses to IFLASH, while it is 16 bit wide for read accesses to IFLASH. Read/write accesses to IFLASH Control Registers area are 16 bit wide. 5.2 Functional description 5.2.1 Structure The following table shows the Address space reserved to the Flash module. Flash Control Bank 0: 256 Kbyte Program Memory HV and Ref. Generator Program/Erase Controller I-BUS Interface + 8 Kbyte Test-Flash IFLASH Control Section Registers Table 4. Address space reserved to the Flash module Description Addresses Size IFLASH sectors 0x00 0000 to 0x04 FFFF 256 Kbyte Reserved IBUS area 0x05 0000 to 0x07 FFFF 192 Kbyte Registers and Flash internal reserved area 0x08 0000 to 0x08 FFFF 64 Kbyte |
