DescriptionRequiredTypeParameter Name

Specifies the oscillator frequency for the user flash

memory. This parameter is used for simulation

purposes only. Values are 180000 ps (5.56 MHz)

or 300000 ps (3.33 MHz). If omitted, the default is

180000 ps. The OSC_FREQUENCY setting

controls the oscillator frequency during simulations

and does not affect the device’s oscillator frequency,

which can range from 3.33 MHz (300000 ps) to

5.56 MHz (180000 ps).

NoIntegerOSC_FREQUENCY

Specifies the internal address width for the user

flash memory.

YesIntegerWIDTH_UFM_ADDRESS

Identifies the library of parameterized modules

(LPM) entity name in VHDL Design Files (.vhd).

NoStringLPM_TYPE

Table 15: ALTUFM_I2CParameters

DescriptionRequiredTypeParameter Name

Specifies the access mode. Values are READ_

WRITE and READ_ONLY. If omitted, the default

is READ_WRITE.

YesStringACCESS_MODE

Create the ALTMULT_ADD IP core with the

parameter editor to calculate the value for this

parameter. (1)

NoStringINTENDED_DEVICE_

FAMILY

Specifies the erase method. Values are MEM_

ADD, A2_ERASE, DEV_ADD_111, and NO_

ERASE. If omitted, the default is MEM_ADD.

NoStringERASE_METHOD

4-bit address that specifies the 4 MSBs of the

device address.

YesStringFIXED_DEVICE_ADD

Name of the Memory Initialization File (.mif) or

Hexadecimal (Intel-Format) Files (.hex)

containing RAM initialization data (<file name>

), or UNUSED. If you use a HEX file to initialize

with the memory, you must use a word size of

16 bits. Data bits need to be located in the MSBs

of the data word and pad the LSBs with 1.

NoStringLPM_FILE

If the ERASE_METHOD parameter has a value

of MEM_ADD, the MEM_ADD_ERASE0

parameter must specify the 8-bit memory address

that erases sector 0 of the UFM block.

NoStringMEM_ADD_ERASE0

If the ERASE_METHOD parameter has a value

of MEM_ADD, the MEM_ADD_ERASE1

parameter must specify the 8-bit memory address

that erases sector 1 of the UFM block.

NoStringMEM_ADD_ERASE1
