Features
Functional Description
The CY7C341B is an Erasable Programmable Logic Device
(EPLD) in which CMOS EPROM cells are used to configure
logic functions within the device. The MAX
100% user-configurable, allowing the devices to accom-
modate a variety of independent logic functions.
The 192 macrocells in the CY7C341B are divided into 12 Logic
Array Blocks (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 interconnect array, allowing all signals to be
routed throughout the chip.
The speed and density of the CY7C341B allows it 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 functionality of 20-pin PLDs,
the CY7C341B allows the replacement of over 75 TTL devices. By
replacing large amounts of logic, the CY7C341B reduces board
space, part count, and increases system reliability.
Each LAB contains 16 macrocells. In LABs A, F, G, and L, 8
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 CY7C341B. 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 programmable 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
macrocells in other LABs as well as the macrocells in the LAB in
which they are situated.
Externally, the CY7C341B 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 bidirectional 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 configuration,
simplifies design by assuring that internal signal skews or
races are avoided. The result is ease of design implemen-
tation, often in a single pass, without the multiple internal logic
placement and routing iterations required for a programmable
gate array to achieve design timing objectives.
Design Recommendations
For proper operation, input and output pins must be
constrained to the range GND < (V
inputs must always be tied to an appropriate logic level (either V
or GND). Each set of V
together directly at the device. Power supply decoupling capacitors
of at least 0.2 F must be connected between V
the most effective decoupling, each V
decoupled to GND, directly at the device. Decoupling capacitors
should have good frequency response, such as monolithic ceramic
types.
