AT89LP51RC2-20PU Frequently Asked Questions (FAQ)
-
The AT89LP51RC2-20PU can operate up to 20 MHz with an external clock source, but it's recommended to check the clock frequency limitations for specific operating conditions and voltage levels in the datasheet.
-
The power consumption in sleep mode (Idle mode) depends on the clock frequency, voltage, and other factors. According to the datasheet, the typical current consumption in Idle mode is around 10 μA at 3V and 4 MHz, but it's recommended to check the datasheet for specific values and conditions.
-
The AT89LP51RC2-20PU has an internal oscillator that can be used, but it's not as accurate as an external crystal oscillator. If high accuracy is required, an external crystal oscillator is recommended. The internal oscillator can be calibrated using the OSCICL trim bits.
-
The AT89LP51RC2-20PU can be programmed using a variety of methods, including in-system programming (ISP), in-application programming (IAP), and programming using a dedicated programmer. The microcontroller supports serial programming mode (SPM) and can be programmed using a serial programmer or a development board.
-
The AT89LP51RC2-20PU has 8 KB of flash memory, and the entire memory space can be programmed. However, some areas of the memory are reserved for the bootloader and other system functions, so the available user program memory is around 7.5 KB.
