PSD8XXF Family
Preliminary Information
6
PSD8XXF devices contain several major functional blocks. Figure 1 on page 3 shows the
architecture of the PSD8XXF device family. The functions of each block are described
briefly in the following sections. Many of the blocks perform multiple functions and are user
configurable.
5.1 Memory
The PSD8XXF contains the following memories:
A 1 or 2 Mbit Flash
A secondary 256 Kbit Flash boot memory
An optional 16 or 64 Kbit SRAM.
Each of the memories is briefly discussed in the following paragraphs. A more detailed
discussion can be found in section 9.
The 1 or 2 Mbit Flash is the main memory of the PSD8XXF. It is divided into eight
equally-sized sectors that are individually selectable.
The 256 Kbit Flash Boot memory is divided into four equally-sized sectors. Each sector is
individually selectable.
The optional 16 or 64 Kbit SRAM is intended for use as a scratchpad memory or as an
extension to the microcontroller SRAM. If an external battery is connected to the
PSD8XXF’s Vstby pin, data will be retained in the event of a power failure.
Each block of memory can be located in a different address space as defined by the user.
The access times for all memory types includes the address latching and DPLD decoding
time.
5.2 Page Register
The eight-bit Page Register expands the address range of the microcontroller by up to
256 times.The paged address can be used as part of the address space to access
external memory and peripherals or internal memory and I/O. The Page Register can also
be used to change the address mapping of blocks of Flash memory into different memory
spaces for in-circuit reprogramming.
5.3 PLDs
The device contains two PLD blocks, each optimized for a different function, as shown in
Table 2. The functional partitioning of the PLDs reduces power consumption, optimizes
cost/performance, and eases design entry.
The Decode PLD (DPLD) is used to decode addresses and generate chip selects for the
PSD8XXF internal memory and registers. The CPLD can implement user-defined logic
functions. The DPLD has combinatorial outputs. The CPLD has 16 Output Micro
Cells
and 3 combinatorial outputs. The PSD8XXF also has 24 Input Micro
Cells that can be
configured as inputs to the PLDs. The PLDs receive their inputs from the PLD Input Bus
and are differentiated by their output destinations, number of Product Terms, and
Micro
Cells.
The PLDs consume minimal power by using Zero-Power design techniques. The speed
and power consumption of the PLD is controlled by the Turbo Bit in the PMMR0 register
and other bits in the PMMR2 registers. These registers are set by the microcontroller at
runtime. There is a slight penalty to PLD propagation time when invoking the non-Turbo
bit.
