One customer is asking about the flash spec of the ADuC812. The datasheets tells, that the data in the flash will remain for 10 years, but this spec is for 5V supply!
What about this spec under 3.3V operation? Also 10 years?
I would like to use the multiprocessor feature of the serial interface of the ADuC812, in which bit 9 causes an serial interrupt if set. Unfortunately I can't get this feature working, so I wonder if there is a software error or if this feature…
Can the PSEN pin be pulled low during the duration of the serial programming or are there any specific timing requirements re this line during serial programming? I am not using any external memory with the ADuC812 so can I leave this pin always…
1)For our needs we found that the total power dissipation of the ADUC821 is typically 100mW. How can we know how long(how many minutes or hours) the micro controller can work before the battery becomes insufficient? 2)In the data sheets we found…
I need more information about the TEMP Sensor of the ADuC812. What I need is the temperature dependance between exteranal temperature and the internal temperature. If I want to messure the external temperature how can I calculate it from the value…
During testing new series of drivers which depend on ADuC812 in one of his dispositon the incident hapend: 1. Microconverter was several times programmed - OK 2. Microconverter worked with different programs - OK 3. During next programming can't…
I have got a new problem with this mico-c, the serial RxD-TxD die, I use the same wiring as mentioned in user's manual chap. 1.11 others hardware considerations. I have downloaded many times and suddently it do not work. Is there any trick ?…
At programming AduC812 of production after 2001 the chip is written 1-2 times by the program download.exe version 2.07 well. At the subsequent attempts to write AduC812 by the program download.exe version 2.07 the reset of the chip and record is…
