PSD MODULE
I
The PSD Module provides configurable
Program and Data memories to the 8032 CPU
core (MCU). In addition, it has its own set of I/O
ports and a PLD with 16 macrocells for general
logic implementation.
I
Ports A,B,C, and D are general purpose
programmable I/O ports that have a port
architecture which is different from the I/O ports
in the MCU Module.
I
The PSD Module communicates with the MCU
Module through the internal address, data bus
(A0-A15, D0-D7) and control signals (RD, WR,
PSEN, ALE, RESET). The user defines the
Decoding PLD in the PSDsoft Development
Tool and can map the resources in the PSD
Module to any program or data address space.
Figure 40 shows the functional blocks in the
PSD Module.
Functional Overview
I
512Kbit Flash memory. This is the main Flash
memory. It is divided into 4 sectors (16KBytes
each) that can be accessed with user-specified
addresses.
I
Secondary 128Kbit Flash boot memory. It is
divided into 2 sectors (8KBytes each) that can
be accessed with user-specified addresses.
This secondary memory brings the ability to
execute code and update the main Flash
concurrently.
I
16Kbit SRAM. The SRAM’s contents can be
protected from a power failure by connecting an
external battery.
I
CPLD with 16 Output Micro Cells (OMCs) and
up to 20 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) that decodes address for
selection of memory blocks in the PSD Module.
I
Configurable I/O ports (Port A,B,C and D) that
can be used for the following functions:
– MCU I/Os
– PLD I/Os
– Latched MCU address output
– Special function I/Os.
– I/O ports may be configured as open-drain
outputs.
I
Built-in JTAG compliant serial port allows full-
chip In-System Programmability (ISP). With it,
you can program a blank device or reprogram a
device in the factory or the field.
I
Internal page register that can be used to
expand the 8032 MCU Module 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 the 8032 CPU
core activity and put the PSD Module 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)
