Working Principle of CY37512P256-83BGC

The CY37512P256-83BGC operates using a programmable logic architecture. The logic cells can be configured to perform the desired logic functions. The design of the programmable logic elements is based on the Altera-Lattice LCP optimized architecture. The user can program the device using VHDL, Verilog, or Quartus II (Altera\'s high-level VLSI design system). Each logic element consists of two 5-input look-up tables (LUTs), one flip-flop, and two clock distribution cells.

The look-up tables are configurable per bit-slice and can represent any combinational or sequential logic function. The flip-flop is a Second Level Storage (LSB) register that stores the logic pattern output by the LUTs. The clock distribution cell is used to synchronize the logic elements. The programmable logic array is interfaced with the logic core and I/O system.

The I/O pin drivers are matched to the package being used so that the device can be interfaced with various types of I/O standards. The device can also be configured to be used with 5V-tolerant I/O. Voltage level shifting and bus emulation circuitry are provided to support the different I/O standards.
