Hello troops,
been looking for a modern 8051 with low power standby (<<0.5mA) and an
internal RTC (hardware RTC).
Does anyone have any ideas?
Yes, I know there are other parts (PIC, AVR, ARM, etc etc etc), but I would
like to stay with the 8051. Also would really like to prevent an external
I2C or SPI RTC if at all possible.
Thanks,
Said
The I2C approach or external spi allows you to just power the RTC part
for low power.
I did an STC I2C part for linux, was not much fuss at all. It would not
be hard to use the linux driver code if you are using c, or if you are
not, it is still simple enough to do in assembler code.
