Philips Development System

for P89LPC900 family Microcontrollers

PDS900

Emulator and Programmer

FEATURES

Emulates and programs Philips P89LPC900 family of high-

performance Flash-memory microcontrollers

DESCRIPTION

The PDS900 is an affordable fully-featured in-circuit emulation

system and device programmer for Philips new P89LPC900

family of high-performance microcontrollers.

Low-cost single-board emulation system with footprint-specific

emulation adaptors and device programming adaptor

Real-time transparent in-circuit emulation to full rated device

speed over full device voltage range

16k bytes for user program code (full extent of P89LPC900

It allows complete control over execution of a user’s program

and access to all internal registers and memory spaces of the

target microcontroller, without consuming any device resources

or introducing other non-standard behaviour, and can program

the Flash program memory and configuration data areas of

packaged devices.

A P89LPC900 family microcontroller in the user’s target system

Real-time trace (112k frames x 32 bits) including 12x user input

Multiple breakpoint sources

can be replaced with an appropriate footprint adaptor connected

via a short flexible ribbon cable to the PDS900 emulator. Program

code can then be loaded into the PDS900 and run, and registers

and data memory can be examined and modified in order to

perform program debugging and optimisation.

programming of the full address range of the P89LPC900 family

(16k bytes), and recording of a trace history comprising 112k

frames of 32-bit data. Trace data is recorded in real time for

every machine cycle and comprises address, status, and 12

channels from external inputs. Additional memory provides

16k breakpoints, ancillary control, and output functions.

Includes emulation footprint adaptors for TSSOP20, TSSOP28 and PLCC28

packages, and a programming adaptor for PLCC28 packages. Emulation and

programming adaptors for other packages available separately.

power supply, allows emulation over the full range of clock

frequencies and supply voltages supported by the target

microcontroller. The microcontroller can be clocked from this

programmable clock source or from the various internal clock

sources of the P89LPC900 family devices. For maximum

convenience the emulator can supply up to 250mA at the

programmed voltage to the user ’s target system, with a

programmable current limit for added protection. An isolated

universal mains power supply is included in the box and

eliminates potential problems with earth loops.

A trigger output permits synchronisation of an external

oscilloscope or logic analyser to any selection of fetch addresses

in the 16k address range, and an external digital input can be

qualified by any selection of fetch addresses in order to break

execution. A continuous clock source with individually-

programmable high and low periods is provided to hold off any

external watchdog when execution of user code is stopped, or

can be used as a basic digital signal source during development.

The PDS900 connects to a host PC via a USB interface that

provides ease of installation and fast communication. A

sophisticated Windows-based debugging and device

programming environment supports all popular code generation

tools from 3rd-party vendors.

The PDS900 design is uniquely “soft” in that all software,

firmware, and programmable logic can be field-upgraded in order

to improve performance or add features. Upgrades are available

free of charge from the Web and the debugger can be configured

to automatically advise of new updates and download and install

them as desired.
