Flash Memory Characteristics
The flash memory characteristics are shown in Table 25 and Table 26.
6 Thermal characterization parameter indicating the temperature difference between package top and the junction
temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written
in conformance with Psi-JT.
The average chip-junction temperature (TJ) in C can be obtained from:
(1)
Where:
TA
= ambient temperature,
C
JA
= package thermal resistance, junction-to-ambient,
C/W
PD
= PINT PI/O
PINT
= chip internal power, IDD VDD, watts
PI/O
= power dissipation on input and output pins — user determined, watts
For most applications PI/O PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is:
(2)
Solving equations 1 and 2 for K gives:
K = PD (TA + 273 C) + JMA PD
2 (3)
where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for
any value of TA.
