Parameters

Parameter Type Required Comments
ACCESS_MODE String No

Specifies the access mode for the user flash memory. Values are "READ_WRITE" and "READ_ONLY". This parameter is used with the parallel or SPI interface protocol only.

ERASE_TIME Integer No

Specifies the erase time for the user flash memory. This parameter is used for simulation purposes only and allows you to shorten the user flash memory simulation time. Values can range from 1600 ns to 999 μs. If omitted, the default value is 500000000ps (500 μs). If you use the ERASE_TIME parameter, the device still requires a maximum of 500 ms to erase.

LPM_FILE String No

Name of the Memory Initialization File (.mif) Definition or Hexadecimal (Intel-Format) File (.hex) Definition containing RAM initialization data ("<file name>"), or "UNUSED". If you use a Hexadecimal (Intel-Format) 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.

OSC_FREQUENCY Integer No

Specifies the oscillator frequency for the user flash memory. This parameter is used for simulation purposes only. Values are 180000 ps (5.56MHz) or 300000 ps (3.33MHz). If omitted, the default value 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 3.33MHz (300000 ps) to 5.56MHz (180000 ps).

PROGRAM_TIME Integer No

Specifies the program time for the user flash memory. This parameter is used for simulation purposes only and allows you to shorten the user flash memory simulation time. Values can range from 1600 ns to 100 μs. If omitted, the default is 1600000ps (1600 ns). If you use the PROGRAM_TIME parameter, the device still requires a maximum value of 100 μs to program.

WIDTH_ADDRESS Integer Yes

Specifies the width for the addr bus. This parameter is used with the parallel interface protocol only.

WIDTH_DATA Integer Yes

Specifies the width for the data bus. This parameter is used with the parallel interface protocol only.

WIDTH_UFM_ADDRESS Integer Yes Specifies the internal address width for the user flash memory.
