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.
