32 Kbyte Flash Module (S12FTS32KV1)
18.1
The
array of
The Flash array may be read as either bytes, aligned words, or misaligned words. Read access time is one
bus cycle for byte and aligned word, and two bus cycles for misaligned words.
The Flash array is ideal for program and data storage for single-supply applications allowing for field
reprogramming without requiring external voltage sources for program or erase. Program and erase
functions are controlled by a command driven interface. The Flash module supports both mass erase and
sector erase. An erased bit reads 1 and a programmed bit reads 0. The high voltage required to program
and erase is generated internally. It is not possible to read from a Flash array while it is being erased or
programmed.
