DESCRIPTION
Added the note “Guaranteed by design; not production tested.” to
several Performance Specifications table parameters (V_OH and V_OL in
the Output Logic Levels table; VBAT current in the Supply Current
table; VREF(T) deviation from VNOM(T) and VBIAS voltage in the
VREF, VBIAS table; Voltage to Current Crosstalk in the ADC
Converter, Voltage to Current Crosstalk V3P3A Referenced table;
Temperature Error in the Temperature Sensor table) and Timing
Specifications table parameters (Reset pulse fall time in the RESET
and V1 table)
Changed the Response Time (V1) condition from ±100mV overdrive to
split +100mV and -100mV overdrive conditions with new MIN and MAX
numbers for -100mV in the Power-Fault Comparator table
Added < 25°C and > 25°C to BROWNOUT mode in the VBAT current
parameter of the Supply Current table
Changed the XIN to XOUT Capacitance parameter from 3pF (max) to
3pF (typ) and changed XIN/XOUT for Capacitance to DGND from 5pF
(max) to 5pF (typ) in the Crystal Oscillator table
Changed the THD (First 10 harmonics) parameters for 250mV-pk and
20mV-pk from -75dB (max) and -90dB (max) to -75dB (typ) and -90dB
(typ) in the ADC Converter, V3P3A Referenced table
Deleted the Optical Interface parameters table
Added part type 71M6521DH
Added description of 71M6521DH in Hardware Overview
Added specification of temperature coefficients TC1/TC2 in Electrical
Specifications for 71M6521DH
Separated numbers from units by one space, e.g. 5 mA.
Rephrased accuracy statement on title page (“up to 0.1% Wh accuracy
over 2,000:1 current range”). Added 20 ppm/°C for 71M6521DH.
Added explanation of how TC1 and TC2 are generated for the
71M6521DH from the TRIMBGA, TRIMBGB, TRIM, and TRIMT fuses.
Corrected ALT MUX Sequence in Table 1
Updated Ordering Information Table (71M6521DH future product).
Added 71M6521DH version to header.
Added 71M6521DH to FLASH memory description.
Changed TRIMM to TRIMM[2:0].
Added formula to convert TC1/TC2 to PPMC1/PPMC2.
Added explanation of “box” temperature concept.
Added description of TRIMSEL[3:0] and TRIM[7:0] to I/O RAM
DESCRIPTION.
Added VREF(T) deviation from VNOM(T) description for 71M6521DH
in VREF, VBIAS section.
Added section explaining the distinction between
71M6521DE/71M6521FE and 71M6521DH parts.
