54 / 106 page ![]() 3-15 DC and Switching Characteristics MachXO2 Family Data Sheet Typical Building Block Function Performance – ZE Devices 1 Pin-to-Pin Performance (LVCMOS25 12mA Drive) Register-to-Register Performance Derating Logic Timing Logic timing provided in the following sections of the data sheet and the Lattice design tools are worst case num- bers in the operating range. Actual delays may be much faster. Lattice design tools can provide logic timing num- bers at a particular temperature and voltage. Function -3 Timing Units Basic Functions 16-bit decoder 13.9 ns 4:1 MUX 10.9 ns 16:1 MUX 12.0 ns Function -3 Timing Units Basic Functions 16:1 MUX 191 MHz 16-bit adder 134 MHz 16-bit counter 148 MHz 64-bit counter 77 MHz Embedded Memory Functions 1024x9 True-Dual Port RAM (Write Through or Normal, EBR output registers) 90 MHz Distributed Memory Functions 16x4 Pseudo-Dual Port RAM (one PFU) 214 MHz 1. The above timing numbers are generated using the Diamond design tool. Exact performance may vary with device and tool version. The tool uses internal parameters that have been characterized but are not tested on every device. |
