TC1793
History
• specify wording for limitation of pad performance in section Extended Range
Operating Conditions
• remove incorrect test conditions for RDSONx parameters
• remove ADC 3 from ADC parameters
• adjust typo in temperature profile
• removed RDSON parameters for class F pads weak driver as only medium is
available
• add parameter f_SYSD for the SYSPLL
• changed RDSON values for class F pads
• updated class B pads rise and fall times definitions
• add RDSON parameters to class B pads
• supply range of 1.8 V for V_DDEBUwas removed
• update all current values of table 28 (Power Supply Parameters)
• rework the 3.3 V current part of the Power Supply Parameters for better description
and usage
– Parameters I_{DDP_FP}, I_DDFL3E and I_DDFL3R are removed and replaced in the following
way
– I_{DDP_FP} is replaced by I_DDP with the condition including flash programming current
– I_DDFL3E is replaced by I_DDP with the condition including flash erase verify current
– I_DDFL3R is replaced by I_DDP with the condition including flash read current
– parameter I_DDFL3R was renamed to I_DDFL3
The rework of the 3.3 V current part of the Power Supply Parameters was done for
simplification and clarification. Former given values could still be used if liked, the new
definition results in the same resulting values or slightly better values. The flash module
is supplied via I_DDFL3 and I_DDP. For the different flash operating modes in worst case
different allocations for the two domains resulting.
The application typical case ‘flash read’ has max I_DDP of 25 mA and max I_DDFL3 of 98 mA
resulting is a sum of 123 mA.
The case ‘flash programming’ has max I_DDP of 55 mA and max I_DDFL3 of 29 mA resulting
is a sum of 84 mA.
The case ‘flash erase verify’ has max I_DDP of 40 mA and max I_DDFL3 of 98 mA resulting
is a sum of 138 mA.
So for the old parameter I_DDP with 35 mA, the new version reads as
I_DDP = 25+I_{DDP_PORST} = 32 mA for the same application relevant case.
The following changes where done between Version 0.7 and 1.0 of this document:
• improve parameters I_DDFL3
• change for parameter N_E note from Max. data retention to Min.
• change description of parameter t_CAL for the ADC
• correct typo for class D pads in tables 14 and 15
• adapt Absolute Maximun Rating
• add footnote to Flash parameter t_ERD
