whose datasheet is offered in the DE2_115_datasheets\IR_Receiver folder on DE2-115 system CD.

Note that for this all-in-one receiver module, it is only compatible with the 38KHz carrier Standard,

with a maximum data rate of about 4kbps for its product information. The accompanied remote

controller with an encoding chip of uPD6121G is very suitable of generating expected infrared

signals. Figure 4-32 shows the related schematic of the IR receiver, and the pin assignments of the

associated interface are listed in Table 4-26.

 SRAM

The DE2-115 board has 2MB SRAM memory with 16-bit data width. Being featured with a

maximum performance frequency of about 125MHz under the condition of standard 3.3V single

power supply makes it suitable of dealing with high-speed media processing applications that need

ultra data throughput. The related schematic is shown in Figure 4-33.
