Introduction
Preliminary
Programmable Peripheral
PSD6XX Family
Field-Programmable Microcontroller Peripherals
with Embedded Micro
Cells
TM
The PSD6XX series is a complete family of Field Programmable Microcontroller Peripherals
with Embedded Micro
Cells
TM
. The devices are used to rapidly implement highly integrated
embedded control systems. The device family offers a variety of functions including PLDs
with embedded Micro
Cells, dynamically reconfigurable I/O Ports, programmable power
management, EPROM, SRAM and other functions.
Drawing from WSI’s years of experience with microcontroller (MCU) applications, the new
PSD6XX product family radically simplifies the addition of programmable logic to embedded
system designs. New innovative “microcontroller-macrocells”, called Micro
Cells, bring
inexpensive programmable logic to MCU-based embedded system designs. Because the
Micro
Cells are directly connected to the system address/data bus, their NVM-based
programmable logic is tightly coupled to the software programs running in the system MCU.
The MCU’s ability to communicate directly with the Micro
Cells at the flip-flop level makes
PSD6XX devices ideal for implementing the functions most frequently needed in embedded
systems.
Communicating with Microcontrollers – Regardless of the function they perform, all micro-
controller peripherals must communicate to the MCU. All MCUs require clock, data bus, chip
select, and read or write signals. To implement these signals using current industry standard
PLDs required the use of valuable product terms and macrocells in each PLD chip.
In the case of most embedded system designs, this left so few remaining usable PLD
resources to implement the peripheral function that designers dismissed the use of a PLD as
too expensive.
The Micro
Cell directly connects its PLD logic to the MCU. The MCU then sees the PLD in
the PSD6XXE1 as a decoded location in the address map. Direct read and write operations
can be easily and simply performed. Functions like counters and serial ports can be
constructed with programmable logic without any design time or resources lost interfacing to
the MCU.
When compared to industry standard CPLD implementations this architecture can save 25%
to 50% of the CPLD product term and macrocell resources.
J
A simple, programmable interface to 8 or 16 bit microcontrollers using either multiplexed
or non-multiplexed busses. The bus interface logic directly decodes microcontroller
control signals. Microcontroller families supported include the Intel 8031, 80196,
80186, 80C251 and 80386EX; Motorola 68HC11, 68HC16, 68HC12 and 683XX; Philips
8031 and 8051XA; National 16000; Zilog Z80 and Z8; and Neuron 3150.
J
Three PLDs with 12 Output Micro
Cells and 23 Input Micro
Cells, 63 inputs and
129 product terms. The PSD6XX PLDs may be used to efficiently implement a variety
of logic functions including state machines and address decoders for internal and
external control. The PLD also provides seven external chip select outputs.
J
Embedded Input and Output Micro
Cells that enable efficient implementation of user
defined system logic functions that require both microcontroller software and hardware
interaction.
J
Power Management Unit that reduces the device standby current to 25 μA typical.
