For the preceding example, with a 3-clock acquisition time, total conversion time is 19 ADC clocks or 9. The microcontroller is an optimized core offering up to 20 MIPS peak performance. To use the internal PLL, connect a Port 2 emits the middle order datazheet byte during accesses to the external bit external data memory space. A block diagram of the TIC is shown in Figure Power-up time for adu8c41 internal reference is determined by the value of the decoupling capacitor chosen for the CREF pin.

Set by the user enabling the response to any interrupt afuc841 be executed at the fastest core clock frequency, regardless of the configuration of the CD2—0 bits see below. Interrupt Priority Interrupt Vectors The interrupt enable registers are written by the user to enable individual interrupt sources, while the interrupt priority registers allow datashwet user to select one of two priority levels for each interrupt.

The lowest 32 bytes are grouped into four banks of eight registers addressed as R0 to R7. The signal is the rms amplitude of the fundamental. But at clock speeds slower that kHz, the ADC can no longer function correctly. Ability to respond to four separate addresses when operating in slave mode. Dahasheet Lifecycle Production At least one model within this product family is in production and available for purchase.


Twenty-Four Hour Select Bit. The external memory must be preconfigured. Port 1 digital output capability is not supported on this device. Cleared by the user to disable the interval counter.

While the stack may reside anywhere in on-chip RAM, the SP register is initialized to 07H after a reset, which causes the stack to begin at location 08H. Normally, this pin is hardwired either high or low to select execution from internal or external program memory space, as described earlier. Port 3 Alternate Pin Functions P3. PSEN enables serial download mode when pulled low through a resistor on power-up or reset. Set by the user to enable the time clock to the time interval counters.

When Timer datasgeet is in Mode 3, Timer 1 can be turned on and off by switching it out of and into its own Mode 3, or it can still be used by the serial interface as a baud rate generator. Cleared by hardware when the program counter PC vectors to the interrupt service routine.

Reduced code range of to adkc841, 0 V to VDD range.

SNR levels of 71 dB are obtained across the sampling range of the parts. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. The divider ratio is selected as follows: There are no restrictions on the duty cycle of the external input signal, but to ensure that a given level is sampled at least once before it changes, it must be held for a minimum of one full machine cycle.


This bit should always contain 0. Set by software to specify edge-sensitive detection, that is, 1-to-0 transition.

A read-only status bit that is set during a valid ADC conversion or during a calibration cycle. The dotted line in Figure 43 indicates the ideal transfer function, and the solid line represents what the transfer function might look like with endpoint nonlinearities due to saturation of the output amplifier.

Therefore, it cannot be accidentally erased or reprogrammed by erroneous code execution, which makes it very suitable to use the 6 kBytes as a bootloader. It indicates when any of the supply pins drops below one of two user selectable voltage trip points, 2. Set by hardware at the end of the 8th bit in Mode 0, or halfway through the stop bit in Modes 1, 2, and 3.

The stack can be located anywhere in the internal memory address space, and the stack depth can be expanded up to bytes. Cleared by the user to enable Timer 1 overflow to be used for the receive clock.

All other on-chip peripherals are, however, shut down. When set, this bit starts the selected calibration cycle. Timer 0 high byte and low byte. TH0 holds a value that dwtasheet to be reloaded into TL0 each time it overflows. Application Note uC at www. This is the date Analog Devices, Inc. T0, T1, or T2.
