7. User Flash Memory in MAX V Devices
January 2011
MV51007-1.1
MV51007-1.1
This chapter provides guidelines for user flash memory (UFM) applications by
describing the features and functionality of the MAX® V UFM block and the
Quartus® II ALTUFM megafunction.
Altera® MAX V devices feature a UFM block that can be used for storing non-volatile
information up to 8 Kbits, similar to a serial EEPROM. The UFM provides an ideal
storage solution that supports all protocols (serial peripheral interface (SPI), parallel,
and other protocols) for interfacing through bridging logic designed into the MAX V
logic array.

UFM Array Description
Each UFM array is organized as two separate sectors with 4,096 bits per sector. Each
sector can be erased independently. Table 7–1 lists the dimensions of the UFM array.
