TC1791
History
• removed RDSON parameters for class F pads weak driver as only medium is
available
• add parameter f_SYSD for the SYSPLL
• 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:
• add product options SAK-TC1791S-512F240EP, SAK-TC1791S-384F200EP, and
SAK-TC1791N-384F200EP
• update block diagrams to cover new options
• add note to TC1791 Logic Symbol figure and pin list for E-RAY pins availability
• add identification registers for new options
• adapt Absolute Maximum Rating
• clarify pad supply levels in Pin Reliability in Overload section
• correct errors for analog inputs in tables 12 and 13
• add note at the end of Pin Reliability in Overload section
• clarify wording for valid operating conditions
• add negative limit for class S pad leakage
• change description of parameter t_CAL for the ADC
• update footnote 10 for the ADC
• split FADC DNL parameter into two conditions and change value for gain 4 and 8
• add footnote 5 to I_DDP
