ADSP-BF538F EZ-KIT Lite Hardware Reference

The core voltage and the core clock rate can be set on the fly by the pro- cessor. The input clock is 25 MHz. A 32.768 kHz crystal supplies the real-time clock (RTC) inputs of the processor. The default boot mode for the processor is flash boot. See “Boot Mode Select Switch (SW3)” on page 2-13for information about changing the default boot mode.

External Bus Interface Unit

The external bus interface unit (EBIU) connects external memory to the ADSP-BF538F processor. The unit includes a 16-bit wide data bus, an address bus, and a control bus. On the EZ-KIT Lite, the EBIU connects to the SDRAM, flash memory, and expansion interfaces.

The 64 Mbytes (32M x 16 bits) of SDRAM connect to the synchronous memory select 0 pin (~SMS0). Refer to “SDRAM Interface” on page 1-8for information about SDRAM configuration. Note that SDRAM clock is the processor’s clock out (CLK OUT), which must not exceed 133 MHz.

The flash memory device connects to the asynchronous memory select sig- nals, ~AMS3 through ~AMS0. The device provides a total of 4 MB of external flash memory or 1 MB of internal flash memory. The processor can use flash memory for both booting and storing information during a standard mode of operation. Refer to “Flash Memory” on page 1-10for details.

All of the address, data, and control signals are available externally via the expansion interface (J1–3). The pinout of these connectors can be found in “ADSP-BF538FEZ-KIT Lite Schematic” on page B-1.
