1
Temperature Range –40°C to +85°C.
2
ADC linearity is guaranteed during normal MicroConverter core operation.
3
ADC LSB size = V
REF
/2
12
, i.e., for internal V
REF
= 2.5 V, 1 LSB = 610 μV, and for external V
REF
= 1 V, 1 LSB = 244 μV.
4
These numbers are not production tested but are supported by design and/or characterization data on production release.
5
Offset and gain error and offset and gain error match are measured after factory calibration.
6
Based on external ADC system components, the user may need to execute a system calibration to remove additional external channel errors to achieve these
specifications.
7
SNR calculation includes distortion and noise components.
8
Channel-to-channel crosstalk is measured on adjacent channels.
9
The temperature monitor gives a measure of the die temperature directly; air temperature can be inferred from this result.
10
DAC linearity is calculated using:
Reduced code range of 100 to 4095, 0 V to V
REF
range.
Reduced code range of 100 to 3945, 0 V to V
DD
range.
DAC output load = 10 k and 100 pF.
11
DAC differential nonlinearity specified on 0 V to V
REF
and 0 V to V
DD
ranges.
12
DAC specification for output impedance in the unbuffered case depends on DAC code.
13
DAC specifications for I
SINK
, voltage output settling time, and digital-to-analog glitch energy depend on external buffer implementation in unbuffered mode. DAC in
unbuffered mode tested with OP270 external buffer, which has a low input leakage current.
14
Measured with C
REF
pin decoupled with 0.47 μF capacitor to ground. Power-up time for the internal reference is determined by the value of the decoupling capacitor
chosen for the C
REF
pin.
15
When using an external reference device, the internal band gap reference input can be bypassed by setting the ADCCON1.6 bit.
16
Flash/EE memory reliability characteristics apply to both the Flash/EE program memory and the Flash/EE data memory.
17
Endurance is qualified to 100,000 cycles as per JEDEC Std. 22 method A117 and measured at –40°C, +25°C, and +85°C. Typical endurance at 25°C is 700,000 cycles.
18
Retention lifetime equivalent at junction temperature (T
J
) = 55°C as per JEDEC Std. 22 method A117. Retention lifetime based on an activation energy of 0.6 eV derates
with junction temperature as shown in Figure 38 in the Flash/EE Memory Reliability section.
19
Power supply current consumption is measured in normal, idle, and 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 (ADuC842/ADuC843), core executing internal
software loop.
Idle Mode:
Reset = 0.4 V, digital I/O pins = open circuit, Core Clk changed via CD bits in PLLCON (ADuC842/ADuC843), PCON.0 = 1, core execution
suspended in idle mode.
Power-Down Mode:
Reset = 0.4 V, all Port 0 pins = 0.4 V, All other digital I/O and Port 1 pins are open circuit, Core Clk changed via CD bits in PLLCON
(ADuC842/ADuC843), PCON.0 = 1, core execution suspended in power-down mode, OSC turned on or off via OSC_PD bit (PLLCON.7) in
PLLCON SFR (ADuC842/ADuC843).
20
DV
DD
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.
21
Power supply currents are production tested at 5.25 V and 3.3 V for a 5 V and 3 V part, respectively.
