The recommended crystal oscillator frequency for the CY8C28545-24AXI is 32.768 kHz. This frequency is used as the clock source for the internal real-time clock (RTC) and watchdog timer.
To configure the CY8C28545-24AXI for low-power operation, you can use the Power Manager component to set the device to a low-power mode, such as Sleep or Hibernate. You can also use the Clock Management component to reduce the clock frequency and disable unused peripherals.
Yes, the CY8C28545-24AXI has an external memory interface that supports asynchronous and synchronous memory interfaces, including SRAM, DRAM, and Flash. You can use the External Memory Interface (EMIF) component to configure the interface and access external memory.
To implement a custom boot loader for the CY8C28545-24AXI, you can use the Bootloader Host (BLH) component to create a custom boot loader that loads firmware from an external source, such as a serial interface or external memory. You will need to write custom code to implement the boot loader logic and interface with the BLH component.
The maximum operating temperature range for the CY8C28545-24AXI is -40°C to +85°C. However, the device can be operated at temperatures up to 105°C for short periods of time, such as during device startup or shutdown.
