Key Features
PSD8XX Family
t A simple interface to 8-bit microcontrollers that use either multiplexed or
non-multiplexed busses. The bus interface logic uses the 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, 80188, 80C251
Motorola 68HC11 and 68HC16
Philips 8031 and 80C51XA
Zilog Z80, Z8 and Z180
Infineon C500 family
t 4 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.
t Internal secondary 256 Kbit Flash boot memory. It is divided into four equal-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.
t 64 Kbit SRAM. The SRAM’s contents can be protected from a power failure by
connecting an external battery.
t CPLD with 16 Output MicroCells (OMCs) and 24 Input MicroCells (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. The CPLD can also generate eight external chip selects.
t Decode PLD (DPLD) that decodes address for selection of internal memory blocks.
t 52 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.
I/O ports may be configured as open-drain outputs.
t Standby current as low as 50 µA for 5 V devices.
t 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.
t Internal page register that can be used to expand the microcontroller address space
by a factor of 256.
t 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 PSD8XX into Power Down Mode.
t Erase/Write cycles:
Flash memory – 100,000 minimum
PLD – 1,000 minimum
