Complex PLD (CPLD)
The CPLD can be used to implement system logic
functions, such as loadable counters and shift reg-
isters, system mailboxes, handshaking protocols,
state machines, and random logic. The CPLD can
also be used to generate three External Chip Se-
lect (ECS0-ECS2), routed to Port D.
Although External Chip Select (ECS0-ECS2) can
be produced by any Output Macrocell (OMC),
these three External Chip Select (ECS0-ECS2) on
Port D do not consume any Output Macrocells
(OMC).
As shown in Figure 11, the CPLD has the following
blocks:
s
24 Input Macrocells (IMC)
s
16 Output Macrocells (OMC)
s
Macrocell Allocator
s
Product Term Allocator
s
AND Array capable of generating up to 137
product terms
s
Four I/O Ports.
Each of the blocks are described in the sections
that follow.
The Input Macrocells (IMC) and Output Macrocells
(OMC) are connected to the PSD8XXFX internal
data bus and can be directly accessed by the
MCU. This enables the MCU software to load data
into the Output Macrocells (OMC) or read data
from both the Input and Output Macrocells (IMC
and OMC).
This feature allows efficient implementation of sys-
tem logic and eliminates the need to connect the
data bus to the AND Array as required in most
standard PLD macrocell architectures.
