AT89LP4052-20SU Frequently Asked Questions (FAQ)

  • The maximum clock frequency for the AT89LP4052-20SU is 20 MHz, as indicated by the '-20' in the part number. However, the device can operate at lower frequencies, and the clock frequency can be divided internally using the clock prescaler.

  • The AT89LP4052-20SU has an internal oscillator that can be configured using the FOSC (Frequency Oscillator Select) bits in the CKCON (Clock Control) register. The oscillator can be set to operate at 12 MHz, 9.6 MHz, or 4 MHz, or it can be disabled to allow an external clock source to be used.

  • The power consumption of the AT89LP4052-20SU depends on the operating frequency, voltage, and mode of operation. According to the datasheet, the typical active mode current consumption is around 10 mA at 20 MHz and 3V, while the idle mode current consumption is around 2 mA. The power-down mode current consumption is typically around 10 uA.

  • The AT89LP4052-20SU can be programmed using a variety of methods, including in-system programming (ISP), in-application programming (IAP), and parallel programming. The device can be programmed using a programmer or a development board, and the programming software is typically provided by the manufacturer or a third-party vendor.

  • The main difference between the AT89LP4052-20SU and the AT89S4052 is the operating voltage range. The AT89LP4052-20SU is a low-power version of the device that operates from 2.7V to 5.5V, while the AT89S4052 operates from 4V to 5.5V. The AT89LP4052-20SU also has a lower power consumption than the AT89S4052.
