STR91xF
Functional overview
29/73
2.24 A/D converter (ADC)
The STR91xF provides an eight-channel, 10-bit successive approximation analog-to-digital
converter. The ADC input pins are multiplexed with other functions on Port 4 as shown in
Table 3
. Following are the major ADC features:
Fast conversion time, as low as 0.7 usec
Accuracy. Integral and differential non-linearity are typically within 4 conversion counts.
0 to 3.6V input range. External reference voltage input pin (AVREF) available on 128-pin
packages for better accuracy on low-voltage inputs. The voltage on AVREF can range
from 1.0V to V
DDQ
.
CPU Firmware may convert one ADC input channel at a time, or it has the option to set the
ADC to automatically scan and convert all eight ADC input channels sequentially before
signalling an end-of-conversion
Automatic continuous conversion mode is available for any number of designated ADC
input channels
Analog watchdog mode provides automatic monitoring of any ADC input, comparing it
against two programmable voltage threshold values. The ADC unit will set a flag or it will
interrupt the CPU if the input voltage rises above the higher threshold, or drops below the
lower threshold.
The ADC unit goes to stand-by mode (very low-current consumption) after any reset event.
CPU firmware may also command the ADC unit to stand-by mode at any time.

2.25 Standard timers (TIM) with DMA
The STR91xF has four independent, free-running 16-bit timer/counter modules designated
TIM0, TIM1, TIM2, and TIM3. Each general purpose timer/counter can be configured by
firmware for a variety of tasks including; pulse width and frequency measurement (input
capture), generation of waveforms (output compare and PWM), event counting, delay timing,
and up/down counting.
Each of the four timer units have the following features:
16-bit free running timer/counter
Internal timer/counter clock source from a programmable 8-bit prescale of the CCU PCLK
clock output
Optional external timer/counter clock source from pin P2.4 shared by TIM0/TIM1, and pin
P2.5 shared by TIM2/TIM3. Frequency of these external clocks must be at least 4 times
less the frequency of the internal CCU PCLK clock output. The Master clock (f
MSTR
) with a
16-bit prescaler can also be selected as an external clock source
Two dedicated 16-bit Input Capture registers for measuring up to two input signals. Input
Capture has programmable selection of input signal edge detection
Two dedicated 16-bit Output Compare registers for generation up to two output signals
PWM output generation with 16-bit resolution of both pulse width and frequency
One pulse generation in response to an external event
A dedicated interrupt to the CPU with five interrupt flags
