KEY FEATURES
I
A simple interface to 8-bit microcontrollers that
use either multiplexed or non-multiplexed
busses. Thebus interface logic usesthe control
signals generated by the microcontroller
automatically when the address is decoded and
a read or write is performed. A partial list of the
MCU families supported include:
– Intel 8031, 80196, 80186, 80C251, and
80386EX
– Motorola 68HC11, 68HC16, 68HC12, and
683XX
– Philips 8031 and 8051XA
– Zilog Z80 and Z8
I
Internal 1 or 2 Mbit Flash memory. This is the
main Flash memory. It is divided into eight
equal-sized blocks that can be accessed with
user-specified addresses.
I
Internalsecondary256 KbitFlashboot memory.
Itis divided into fourequal-sized blocks that can
be accessed with user-specified addresses.
This secondary memory brings the ability to
execute code and update the main Flash
concurrently
.
I
Optional 16, 64or 256 Kbit SRAM. TheSRAM’s
contents can be protected from a power failure
by connecting an external battery.
I
CPLD with 16 Output Micro Cells (OMCs) and
24 Input Micro Cells (IMCs). The CPLD may be
used to efficiently implement a variety of logic
functions for internal and external control.
Examples include state machines, loadable
shift registers, and loadable counters.
I
Decode PLD (DPLD) thatdecodes address for
selection of internal memory blocks.
I
27 individually configurable I/O port pins that
can be used for the following functions:
– MCU I/Os
– PLD I/Os
– Latched MCU address output
– Special function I/Os.
– 16 of the I/O ports may be configured as
open-drain outputs.
I
Standby current as lowas 50
μ
Afor 5 Vdevices.
I
Built-in JTAG compliant serial port allows full-
chip In-System Programmability (ISP). With it,
you canprogram a blank device orreprogram a
device in the factory or the field.
I
Internal page register that can be used to
expand the microcontroller address space by a
factor of 256.
I
Internal programmable Power Management
Unit (PMU) that supports a low power mode
called Power Down Mode. The PMU can
automatically detect a lack of microcontroller
activity and put the PSD8XXF into Power-down
mode.
I
Erase/Write cycles:
– Flash memory – 100,000 minimum
– PLD – 1,000 minimum
– Data Retention: 15 year minimum (for Main
Flash memory, Boot, PLD and Configuration
bits)
