Note to Table 18:
(1) The Texas Instruments (TI) naming conventions differ from those of Altera
Corporation. The TI data sheet for the DAC 904 D/A converter lists bit 1 as the
most significant bit (MSB) and bit 14 as the least significant bit (LSB).
SRAM Memory (U43 & U44)
U43 and U44 are two 256 Kbyte x 16-bit asynchronous SRAM devices.
They are connected to the Stratix II device so they can be used by a
Nios® II embedded processor as general-purpose memory. The two 16-bit
devices can be used in parallel to implement a 32-bit wide memory
subsystem.
Table 19 lists the reference information for the SRAM memory.
