3.7 Data Memory STOP Mode Low Supply Voltage Data Retention Characteristics 
(T
A = −40 to +105°C, VSS = 0 V) 
Parameter Symbol  Conditions  MIN. TYP. MAX. Unit 
Data retention supply voltage  VDDDR 
1.44
Note
 5.5 V 
Note  The value depends on the POR detection voltage. When the voltage drops, the data is retained before a 
POR reset is effected, but data is not retained when a POR reset is effected.

Number of data flash rewrites 
Notes 1,2,3
Retained for 1 years
TA = 25°C   1,000,000 
Retained for 5 years  TA = 85°C 100,000    
Retained for 20 years
TA = 85°C 10,000    
Notes 1.  1 erase + 1 write after the erase is regarded as 1 rewrite.The retaining years are until next rewrite 
after the rewrite. 
  2.  When using flash memory programmer and Renesas Electronics self programming library. 
  3.  These are the characteristics of the flash memory and the results obtained from reliability testing by 
Renesas Electronics Corporation.
