... Description The ATF1502AS is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 32 logic macrocells and inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1502AS’s enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications ...

Block Diagram 32 Each of the 32 macrocells generates a buried feedback that goes to the global bus. Each input and I/O pin also feeds into the global bus. The switch matrix in each logic block then selects 40 individual ...

... Atmel provides ISP hardware and software to allow programming of the ATF1502AS via the PC. ISP is performed by using either a download cable, a comparable board tester or a simple microprocessor interface. When using the ISP hardware or software to program the ATF1502AS devices, four I/O pins must be reserved for the JTAG interface. However, the logic features that the macrocells have associated with these I/O pins are still available to the design for burned logic functions ...
