Philips Development System for P89LPC900 family Microcontrollers
SPECIFICATIONS
PDS900
Architecture
Single-board in-circuit emulator
Footprint specific emulation adaptor
Programmer with package adaptors
Fast USB interface to host PC (cable included)
Windows-based debugger
Field-upgradeable FPGA logic and control firmware
Emulation
Transparent (except steals 2 bytes of stack)
Real-time to beyond rated target device speed
Full 16k bytes of memory for user programs
Trace Memory
112k frames deep, 32 bits wide
One frame recorded per machine cycle:
14-bit program address
Cycle status (instruction fetch, operand
fetch, interrupt, idle, etc.)
12x digital user input signal channels
Breakpoints
16k on program fetch address (hardware)
16k on fetch address and external input
Break on trace full (112k frames)
Break after N instructions (N=1..2 32 )
Break on fetch outside valid program
Trigger Output
For synchronising external equipment
16k trigger points on program fetch address
4 modes each (none, pulse-invert, set, clear)
Other Interface Signals
Watchdog output - to hold off external watchdog
resets when execution stopped, or use as basic
digital signal source (independently programmable
high - low period from 100us to 6s in 100us steps)
Uncommitted input for future feature
Optional reset to user’s target system
Processor Clock
From internal device clock sources or external
PLL synthesiser with quartz crystal reference
Synthesiser programmable from 25kHz to 100MHz
at better than 0.1% accuracy for any frequency
(usable upper freq. limited by target device)
Optimise for PLL jitter or frequency accuracy
Processor clock may be optionally routed to target
Processor and System Power Supply
Programmable from 0 to 3.6V in 25mV steps
(usable lower voltage limited by target device)
Up to 250mA at the programmed voltage can
optionally be supplied to target with current
limit programmable in 1mA steps
Supplied with isolated universal mains power supply
Indicators
System power
USB communications/system activity
Microcontroller running (executing user code)
Microcontroller in idle state
Microcontroller in power-down state
Microcontroller in reset state
Current-limit exceeded
Physical and Environmental
Board-level product in shielded plastic base
130 x 110 x 15mm (excluding adaptors, etc.)
Complies with European CE specifications
Programming Adaptor
Parallel mode for maximum functionality
Detects device presence and correct orientation
Connects in place of emulation footprint adaptor
Supported by Windows debugging environment
PLCC28 socket on-board for low-volume use
Package adaptors available for higher volume use
(PLCC28) and other device packages
Start button and Pass/Fail LED indicators
WINDOWS DEBUGGING ENVIRONMENT
Requirements

Trace record
Watch (display/modify) any SFR or variable in any
supported format:
binary, octal, hex, unsigned, signed, float, ASCII
character, Pascal or C string (numerical
values from 1..4 bytes, big- or little-endian)
Emulation Controls (representative subset)
Reset target
Set execution point (PC)
Run/Stop
Run until instruction at cursor
Step/Step N times
Step into procedure/function
Step over procedure/function
Leave (run until procedure/function exits)
Follow (reposition view at destination of instruction)
Clear trace buffer
Run until trace buffer full or filled again
Program/verify device Flash program array
Program/verify device configuration data
Trace Display
112k lines (frames)
Address, Status, 12x digital user inputs
Disassembly of executed instruction
Special cycles (eg INTACK) highlighted
