The CY7C63612/13 microcontrollers provide 256 bytes of data RAM. In normal usage, the SRAM is partitioned into four areas:
program stack, data stack, user variables and USB endpoint FIFOs as shown below:
after reset
Address
8-bit PSP
0x00
Program Stack begins here and grows upward
8-bit DSP
user
Data Stack begins here and grows downward
The user determines the amount of memory required
User Variables
0xE8
USB FIFO for Address A endpoint 2
0xF0
USB FIFO for Address A endpoint 1
