Table 2-5. PLL Signal Descriptions
For more information on the PLL, please see details of additional technical documentation at the end of this data
sheet.
sysMEM Memory
The MachXO1200 and MachXO2280 devices contain sysMEM Embedded Block RAMs (EBRs). The EBR consists
of a 9-Kbit RAM, with dedicated input and output registers.
sysMEM Memory Block
The sysMEM block can implement single port, dual port, pseudo dual port, or FIFO memories. Each block can be
used in a variety of depths and widths as shown in Table 2-6.
