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 2 Mbit Flash memory. This is the main
Flash memory. It is divided into 8 equal-sized
blocks thatcanbeaccessed with user-specified
addresses.
I
Internalsecondary256 KbitFlash bootmemory.
Itisdivided into4equal-sized blocks thatcanbe
accessed with user-specified addresses. This
secondary memorybrings theability to execute
code and update the main Flash concurrently
.
I
Internal 64 Kbit SRAM. The SRAM’s contents
can be protected from a power failure by
connecting an external battery.
I
CPLD with 16 Output macrocells (OMCs) and
24 Input macrocells (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 low as 25
μ
A.
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 PSD 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)
