  192-macrocell max ? epld cy7c341 cypress semiconductor corporation  3901 north first street  san jose  ca 95134  408-943-2600 document #: 38-03034 rev. *a revised december 11, 2001 41 features ? 192 macrocells in 12 logic array blocks (labs)  eight dedicated inputs, 64 bidirectional i/o pins  0.8-micron double-metal cmos eprom technology  programmable interconnect array  384 expander product terms  available in 84-pin hlcc, plcc, and pga packages functional description the cy7c341 is an erasable programmable logic device (epld) in which cmos eprom cells are used to configure logic functions within the device. the max ? architecture is 100% user-configurable, allowing the devices to accom- modate a variety of independent logic functions. the 192 macrocells in the cy7c341 are divided into 12 labs, 16 per lab. there are 384 expander product terms, 32 per lab, to be used and shared by the macrocells within each lab. each lab is interconnected with a programmable inter- connect array, allowing all signals to be routed throughout the chip. the speed and density of the cy7c341 allows them to be used in a wide range of applications, from replacement of large amounts of 7400-series ttl logic, to complex controllers and multifunction chips. with greater than 37 times the function- ality of 20-pin plds, the cy7c341 allows the replacement of over 75 ttl devices. by replacing large amounts of logic, the cy7c341 reduces board space and part count, and increases system reliability. each lab contains 16 macrocells. in labs a, f, g, and l, eight macrocells are connected to i/o pins and eight are buried, while for labs b, c, d, e, h, i, j, and k, four macrocells are connected to i/o pins and 12 are buried. moreover, in addition to the i/o and buried macrocells, there are 32 single product term logic expanders in each lab. their use greatly enhances the capability of the macrocells without increasing the number of product terms in each macrocell. logic array blocks there are 12 logic array blocks in the cy7c341. each lab consists of a macrocell array containing 16 macrocells, an expander product term array containing 32 expanders, and an i/o block. the lab is fed by the programmable interconnect array and the dedicated input bus. all macrocell feedbacks go to the macrocell array, the expander array, and the program- mable interconnect array. expanders feed themselves and the macrocell array. all i/o feedbacks go to the programmable interconnect array so that they may be accessed by macro- cells in other labs as well as the macrocells in the lab in which they are situated. externally, the cy7c341 provides eight dedicated inputs, one of which may be used as a system clock. there are 64 i/o pins that may be individually configured for input, output, or bidirec- tional data flow. programmable interconnect array the programmable interconnect array (pia) solves inter- connect limitations by routing only the signals needed by each logic array block. the inputs to the pia are the outputs of every macrocell within the device and the i/o pin feedback of every pin on the device. unlike masked or programmable gate arrays, which induce variable delay dependent on routing, the pia has a fixed delay. this eliminates undesired skews among logic signals, which may cause glitches in internal or external logic. the fixed delay, regardless of programmable interconnect array config- uration, simplifies design by assuring that internal signal skews or races are avoided. the result is ease of design imple- mentation, often in a single pass, without the multiple internal logic placement and routing iterations required for a program- mable gate array to achieve design timing objectives. timing delays timing delays within the cy7c341 may be easily determined using warp ? , warp professional ? , or warp enterprise ? software. the cy7c341 has fixed internal delays, allowing the user to determine the worst case timing delays for any design. design recommendations for proper operation, input and output pins must be constrained to the range gnd < (v in or v out ) < v cc . unused inputs must always be tied to an appropriate logic level (either v cc or gnd). each set of v cc and gnd pins must be connected together directly at the device. power supply decoupling capacitors of at least 0.2 f must be connected between v cc and gnd. for the most effective decoupling, each v cc pin should be separately decoupled to gnd, directly at the device. decoupling capacitors should have good frequency response, such as monolithic ceramic types. design security the cy7c341 contains a programmable design security feature that controls the access to the data programmed into the device. if this programmable feature is used, a proprietary design implemented in the device cannot be copied or retrieved. this enables a high level of design control to be obtained since programmed data within eprom cells is invisible. the bit that controls this function, along with all other program data, may be reset simply by erasing the device. the cy7c341 is fully functionally tested and guaranteed through complete testing of each programmable eprom bit and all internal logic elements thus ensuring 100% programming yield. the erasable nature of these devices allows test programs to be used and erased during early stages of the production flow. the devices also contain on-board logic test circuitry to allow verification of function and ac specification once encapsu- lated in non-windowed packages.
