Temperature range is for ADuC845BS; for the ADuC847BS and ADuC848BS (MQFP package), the range is –40°C to +125°C.
Temperature range for ADuC845BCP, ADuC847BCP, and ADuC848BCP (LFCSP package) is –40°C to +85°C.
2
These numbers are not production tested but are guaranteed by design and/or characterization data on production release.
3
System zero-scale calibration can remove this error.
4
Gain error drift is a span drift. To calculate full-scale error drift, add the offset error drift to the gain error drift times the full-scale input.
5
In general terms, the bipolar input voltage range to the primary ADC is given by the ADC range = ±(VREF 2RN )/1.25, where:
VREF = REFIN(+) to REFIN(–) voltage and VREF = 1.25 V when internal ADC VREF is selected. RN = decimal equivalent of RN2, RN1, RN0. For example, if VREF = 2.5 V and RN2,
RN1, RN0 = 1, 1, 0, respectively, then the ADC range = ±1.28 V. In unipolar mode, the effective range is 0 V to 1.28 V in this example.
6
1.25 V is used as the reference voltage to the ADC when internal VREF is selected via XREF0/XREF1 or AXREF bits in ADC0CON2 and ADC1CON, respectively.
(AXREF is available only on the ADuC845.)
7
In bipolar mode, the auxiliary ADC can be driven only to a minimum of AGND – 30 mV as indicated by the auxiliary ADC absolute AIN voltage limits. The bipolar range
is still –VREF to +VREF.
8
DAC linearity and ac specifications are calculated using a reduced code range of 48 to 4095, 0 V to VREF, reduced code range of 100 to 3950, 0 V to VDD.
9
Endurance is qualified to 100 kcycle per JEDEC Std. 22 method A117 and measured at –40°C, +25°C, +85°C, and +125°C. Typical endurance at 25°C is 700 kcycles.
10
Retention lifetime equivalent at junction temperature (TJ) = 55°C per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 eV derates
with junction temperature.
11
Power supply current consumption is measured in normal mode following the power-on sequence, and in power-down modes under the following conditions:
Normal mode: reset = 0.4 V, digital I/O pins = open circuit, Core Clk changed via CD bits in PLLCON, core executing internal software loop.
Power-down mode: reset = 0.4 V, all P0 pins and P1.2 to P1.7 pins = 0.4 V. All other digital I/O pins are open circuit, core Clk changed via CD bits in PLLCON, PCON.1 = 1,
core execution suspended in power-down mode, OSC turned on or off via OSC_PD bit (PLLCON.7) in PLLCON SFR.
12
DVDD power supply current increases typically by 3 mA (3 V operation) and 10 mA (5 V operation) during a Flash/EE memory program or erase cycle.
General Notes about Specifications
DAC gain error is a measure of the span error of the DAC.
The ADuC845BCP, ADuC847BCP, and ADuC848BCP (LFCSP package) have been qualified and tested with the base of the LFCSP
package floating. The base of the LFCSP package should be soldered to the board, but left floating electrically, to ensure good
mechanical stability.
Flash/EE memory reliability characteristics apply to both the Flash/EE program memory and Flash/EE data memory.
