PSD813F devices contain several major functional blocks. Figure 1 on page 3 shows the
architecture of the PSD813F 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 PSD813F contains the following memories:
A 1 Mbit Flash
An optional secondary 256 Kbit EEPROM or Flash boot memory
An optional 16 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 Mbit Flash is the main memory of the PSD813F. It is divided into eight equally-sized
sectors that are individually selectable.
The optional 256 Kbit EEPROM or Flash is divided into four equally-sized sectors. Each
sector is individually selectable.
The optional 16 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 PSD813F’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
PSD813F 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 PSD813F 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 (ZPSD only) 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 ZPSD features.
