TM USE ULTRA37000 FOR CY7C344 ALL NEW DESIGNS 32-Macrocell MAX EPLD densest EPLD of this size. Eight dedicated inputs and 16 Features bidirectional I/O pins communicate to one logic array block. In High-performance, high-density replacement for TTL, the CY7C344 LAB there are 32 macrocells and 64 expander 74HC, and custom logic product terms. When an I/O macrocell is used as an input, two expanders are used to create an input path. Even if all of the 32 macrocells, 64 expander product terms in one LAB I/O pins are driven by macrocell registers, there are still 16 8 dedicated inputs, 16 I/O pins buried registers available. All inputs, macrocells, and I/O pins are interconnected within the LAB. 0.8-micron double-metal CMOS EPROM technology The speed and density of the CY7C344 makes it a natural for 28-pin, 300-mil DIP, cerDIP or 28-pin HLCC, PLCC all types of applications. With just this one device, the designer package can implement complex state machines, registered logic, and combinatorial glue logic, without using multiple chips. This Functional Description architectural flexibility allows the CY7C344 to replace Available in a 28-pin, 300-mil DIP or windowed J-leaded multichip TTL solutions, whether they are synchronous, ceramic chip carrier (HLCC), the CY7C344 represents the asynchronous, combinatorial, or all three. 1 Logic Block Diagram Pin Configurations HLCC 15(22) INPUT INPUT 1(8) Top View 15(23) INPUT INPUT/CLK 2(9) 27(6) INPUT INPUT 13(20) 28(7) INPUT INPUT 14(21) 43 2 1 28 27 26 5 I/O 25 I/O 6 I/O MACROCELL 2 MACROCELL 1 I/O 3(10) INPUT 24 7 23 INPUT INPUT I/O 4(11) MACROCELL 4 MACROCELL 3 8 INPUT 22 INPUT G MACROCELL 6 MACROCELL 5 I/O 5(12) I 9 INPUT/CLK 21 INPUT L I/O 6(13) MACROCELL 8 MACROCELL 7 O 10 20 INPUT I/O O 11 19 I/O I/O 9(16) I/O MACROCELL 10 MACROCELL 9 12 13 14 1516 1718 B C I/O 10(17) MACROCELL 12 MACROCELL 11 A O I/O 11(18) MACROCELL 14 MACROCELL 13 L N MACROCELL 16 MACROCELL 15 I/O 12(19) T CerDIP I/O 17(24) MACROCELL 18 MACROCELL 17 B Top View R I/O 18(25) MACROCELL 20 MACROCELL 19 U O I/O 19(26) MACROCELL 22 MACROCELL 21 INPUT INPUT S 1 28 L INPUT/CLK INPUT I/O 20(27) 2 27 MACROCELL 24 MACROCELL 23 I/O I/O 3 26 MACROCELL 26 MACROCELL 25 I/O 23(2) I/O 4 25 I/O I/O 24(3) MACROCELL 28 MACROCELL 27 I/O I/O 5 24 I/O 25(4) MACROCELL 30 MACROCELL 29 I/O I/O 6 23 I/O 26(5) MACROCELL 32 MACROCELL 31 V V CC 7 22 CC GND GND 8 21 I/O I/O 9 20 I/O I/O 10 19 32 64 EXPANDER PRODUCT TERM ARRAY I/O I/O 11 18 I/O I/O 12 17 INPUT INPUT 13 16 INPUT INPUT 14 15 Selection Guide 7C344-15 7C344-20 7C344-25 Unit Maximum Access Time 15 20 25 ns Maximum Operating Current Commercial 200 200 200 mA Military 220 220 Industrial 220 220 220 Maximum Standby Current Commercial 150 150 150 mA Military 170 170 Industrial 170 170 170 Note: 1.
