Flash Memory Programming (all Ax-steps)
1. Flash Memory Overview
The C167CS-32F/ C161CI-32F/ C161SI-32F devices provide 256 KBytes of flash memory on-chip
for both instruction code and constant data. The flash memory is segmented in 8 flash sectors of 32
KBytes each (all Ax steps).
The lower 32 KBytes of the on-chip flash memory of the C167CS-32F/ C161CI-32F/ C161SI-32F
devices can be mapped to either segment 0 (00’0000
H
to 00’7FFF
H
) or segment 1 (01’0000
H
to
01’7FFF
H
) during the initialization phase to allow external memory to be used for additional system
flexibility. The upper 224 KBytes of the on-chip flash memory are assigned to locations 01’8000
H
to
04’FFFF
H
