architecture
The TMS28F200Axy uses a blocked architecture to allow independent erasure of selected memory blocks. The
block to be erased is selected by using any valid address within that block.
block-memory maps
The TMS28F200Axy is available with the block architecture mapped in either of two configurations: the boot
block located at the top or at the bottom of the memory array, as required by different microprocessors. The
TMS28F200AxB (bottom boot block) is mapped with the 16K-byte boot block located at the low-order address
range (00000h to 01FFFh). The TMS28F200AxT (top boot block) is inverted with respect to the
TMS28F200AxB with the boot block located at the high-order address range (1E000h to 1FFFFh). Both of these
address ranges are for word-wide mode. The TMS28F002Axy is mapped as the 8-bit configuration of the
TMS28F200Axy, except that the least signficant bit (LSB) is A0 instead of A
–1
. Figure 1 and Figure 2 show the
memory maps for these configurations.
