DESCRIPTION
The M39832 is a memory device combining Flash
and EEPROM into a single chip and using single
supply voltage. The memory is mapped in two
arrays: 8 Mbit of Flash memory and 256 Kbit of
EEPROM memory. Each space is independant for
writing, in concurrent mode the Flash Memory can
be read while the EEPROM is being written.
An additional 64 bytes of EPROM are One Time
Programmable.
The M39832 EEPROM memory array is organized
in byte only (regardless on the BYTE pin). It may
be written by byte or by page of 64 bytes and the
integrity of the data can be secured with the help
of the Software Data Protection (SDP).
