MPC5777M Microcontroller Data Sheet, Rev. 6Electrical characteristicsNXP Semiconductors823.15.3 Flash memory Array Integrity and Margin Read specificationsTable 42. Flash memory Array Integrity and Margin Read specifications (characterized but not tested)Symbol Characteristic Min Typical Max 11 Array Integrity times need to be calculated and are dependent on system frequency and number of clocks per read.The equation presented require Tperiod (which is the unit accurate period, thus for 200 MHz, Tperiod would equal5e-9) and Nread (which is the number of clocks required for read, including pipeline contribution. Thus for a read setupthat requires 6 clocks to read with no pipeline, Nread would equal 6. For a read setup that requires 6 clocks to read,and has the address pipeline set to 2, Nread would equal 4 (or 6 - 2).)Units 22 The units for Array Integrity are determined by the period of the system clock. If unit accurate period is used in theequation, the results of the equation are also unit accurate.tai16kseq Array Integrity time for sequential sequence on 16KB block. — — 512 ×Tperiod ×Nread—tai32kseq Array Integrity time for sequential sequence on 32KB block. — — 1024 ×Tperiod ×Nread—tai64kseq Array Integrity time for sequential sequence on 64KB block. — — 2048 ×Tperiod ×Nread—tai256kseq Array Integrity time for sequential sequence on 256KB block. — — 8192 ×Tperiod ×Nread—taifullseq Array Integrity time for sequential sequence full array. — — 3.77e5 ×Tperiod ×Nread—taifullprop Array Integrity time for proprietary sequence (applies to fullarray or single block).— — 9.96e6 ×Tperiod ×Nread—t mr16kseq Margin Read time for sequential sequence on 16KB block. 73.81 — 110.7 μst mr32kseq Margin Read time for sequential sequence on 32KB block. 128.43 — 192.6 μst mr64kseq Margin Read time for sequential sequence on 64KB block. 237.65 — 356.5 μst mr256kseq Margin Read time for sequential sequence on 256KB block. 893.01 — 1,339.5 μstmrfull Margin Read time for sequential sequence full array. 45.21 — 60.26 ms
