DESCRIPTION
The M39208 is a memory device combining Flash
and EEPROM into a single chip and using single
supply voltage. The memory is mapped in two
blocks: 2 Mbit of Flash memory and 64 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.
