26 / 86 page 2–18 Chapter 2: MAX II Architecture User Flash Memory Block MAX II Device Handbook © October 2008 Altera Corporation User Flash Memory Block MAX II devices feature a single UFM block, which can be used like a serial EEPROM for storing non-volatile information up to 8,192 bits. The UFM block connects to the logic array through the MultiTrack interconnect, allowing any LE to interface to the UFM block. Figure 2–15 shows the UFM block and interface signals. The logic array is used to create customer interface or protocol logic to interface the UFM block data outside of the device. The UFM block offers the following features: ■ Non-volatile storage up to 16-bit wide and 8,192 total bits ■ Two sectors for partitioned sector erase ■ Built-in internal oscillator that optionally drives logic array ■ Program, erase, and busy signals Figure 2–14. Global Clock Network (Note 1) Notes to Figure 2–14: (1) LAB column clocks in I/O block regions provide high fan-out output enable signals. (2) LAB column clocks drive to the UFM block.
