Based on the second-generation MAX architecture, it offers 128 macrocells organized into 8 Logic Array Blocks (LABs), each containing 16 macrocells. The device provides 2500 usable gates and 84 I\/O pins, making it suitable for medium-complexity digital logic implementations. The MAX 7000S architecture supports in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, allowing designers to reprogram the device directly on the PCB without removing it from the system. Each macrocell features a programmable register that can be configured as D, T, JK, or SR flip-flop, with programmable clock control including global clock, clock enable, and product-term clock modes. The device also incorporates shareable and parallel expander product terms to supplement macrocell logic resources for implementing complex functions. With 10ns pin-to-pin propagation delay, the EPM7128SQI100-10N is well-suited for high-speed digital applications.","working_principle":"The EPM7128SQI100-10N operates using a Logic Array Block (LAB) based architecture. Each LAB contains 16 macrocells, a shared logic array with 16 shareable expanders, and a local interconnect. Each macrocell consists of a programmable AND\/OR logic array, a configurable register, and I\/O control blocks. The Programmable Interconnect Array (PIA) routes signals between LABs and from I\/O pins. Product terms from the logic array feed into the macrocell's register for clocked operations or bypass it for combinatorial functions. The JTAG interface enables ISP by writing configuration data to the on-chip EEPROM, which retains the programming even when power is removed. Expander product terms (shareable and parallel) allow logic functions exceeding the 5 native product terms per macrocell to be implemented without consuming additional macrocells.","pin_description":"
