XC2385A, XC2387A
XC2000 Family / Base Line
Summary of Features
The XC238xA types are offered with several SRAM memory sizes. Figure 1 shows the
allocation rules for PSRAM and DSRAM. Note that the rules differ:
• PSRAM allocation starts from the lower address
• DSRAM allocation starts from the higher address
For example 8 Kbytes of PSRAM will be allocated at E0’0000h-E0’1FFFh and 8 Kbytes
of DSRAM will be at 00’C000h-00’DFFFh.
