tPCFG (Typ) = 6.146/FMRPCLK + 0.3133 [msec], tPCFG (Max) = 266.5/FMRPCLK + 6.331 [msec] for normal program mode.

tPCFG (Typ) = 5.184/FMRPCLK + 0.02754 [msec], tPCFG (Max) = 267.5/FMRPCLK + 6.025 [msec] for high speed program mode.

Note 6. Read and program operations for the extra MRAM cannot be executed simultaneously. This value is for independent program

operation without arbitration between read and program.

Note 7. The update cycle is the number of a configuration set command that can be issued configuration area. Programming the same data

to the same address also increases the update cycle count by one.

Note 1. The reference value at VCC = 3.3 V and room temperature.

Note 2. Perform rewrite 50% of bits at Typ. condition.

Note 3. To calculate the updating time at other frequencies, using approximate formula below listed. (FMRPCLK: frequency of MRPCLK

[MHz])

tOTPE (Typ) = 0.5065/FMRPCLK + 8.123 [ms], tOTPE (Max) = 4.433/FMRPCLK + 114.1 [ms] for normal speed mode.

tOTPE (Typ) = 0.3389/FMRPCLK + 4.067 [ms], tOTPE (Max) = 2.428/FMRPCLK + 57.08 [ms] for high speed mode 0.

tOTPE (Typ) = 0.1458/FMRPCLK + 0.2312 [ms], tOTPE (Max) = 0.3904/FMRPCLK + 3.166 [ms] for high speed mode 1.

Note 4. Read and program operations for the extra MRAM cannot be executed simultaneously. This value is for independent program

operation without arbitration between read and program.
