1143 / 1504 page  Section 25 Flash Memory Rev. 2.00 Sep. 24, 2008 Page 1111 of 1468 REJ09B0412-0200 25.4 Block Structure 25.4.1 Block Diagram of H8SX/1663 Figure 25.4 (1) shows the block structure of the 384-Kbyte user MAT. The heavy-line frames indicate the erase blocks. The thin-line frames indicate the programming units and the values inside the frames stand for the addresses. The user MAT is divided into five 64-Kbyte blocks, one 32-Kbyte block, and eight 4-Kbyte blocks. The user MAT can be erased in these divided block units. Programming is done in 128-byte units starting from where the lower address is H'00 or H'80. RAM emulation can be performed in the eight 4-Kbyte blocks.
