The second generation FLASH for M•CORE (SGFM) is constructed with
building blocks of 32,768 by 16 bits that can be used to generate 128-,
256-, 384- and 512-Kbyte electrically erasable and programmable
read-only memory arrays using two, four, six, and eight blocks
respectively. The SGFM is ideal for program and data storage for
single-chip applications and allows for field reprogramming without
external high-voltage sources.
The voltages required to program and erase the FLASH is generated
internally by on-chip charge pumps. Program and erase operations are
performed under CPU control through a command driven interface to an
internal state machine. All FLASH physical blocks can be programmed
or erased at the same time; however, it is not possible to read from a
FLASH physical block while the same block is being programmed or
erased. For 256-Kbyte and larger arrays, it is possible to program or
erase one pair of FLASH physical blocks under the control of software
routines executing out of another pair.
