7.4 SPI Timing
8 Monitoring Functions
For measurement reasons the voltages are scaled to low voltage domain V33I. For scaling factors please read Table
Electrical Characteristics section
For error calculations refer following tolerances: Divider, ADC, V33I Supply (tolerance depend on configuration and
Mode).
8.1 Analog Monitoring Functions
As described in section
• Temperature voltage
• Band gap voltage
• Bus voltage
8.2 Digital Monitoring Functions
ADC unit converts a configurable count of analog signals
to 8 bit resolution digital numbers. The signal conversion
time of a selected channel is typical 5 µs at a clock fre-
quency of 4 MHz. The input channels are converted in a
continuously running conversion cycle. The ADC embed-
ded system consists of:
8 bit SAR ADC Core
• high and low level reference generator
• conversion channel mux with input buffer
• channel sequence control unit
• result registers
ELMOS Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
