Take a look at our new forums. If you have a question about the 8xC51, LPC900, or MX families (or any 8051-related query) then ask your question here.

| Emulation and flash magic |
|
Hey everyone, hopefully this is my last question. Why is it that I can run my program fine when using the PDS emulator but when flash my device using flash magic with the same hex file my device doesnt run. PDS is telling me that my UCFG values have been read from the object file so its not that, what else do I need to look at ?
many thanx
Xarion

PDB591-551 |
|
|
PDS51 Daughterboard for P8xC591 and P8x551/553 Devices |
|
|
|
|
The PDB591-551 is a versatile bondout-based daughterboard which forms the basis for an affordable fully-featured in-circuit emulation system. In combination with a PDS51-Mk2A motherboard it emulates the 8xC591, 8xC551, and 8xC553 variants of Philips 8051-derived microcontrollers.
A footprint adaptor compatible with a standard PLCC44 device socket is supplied. A footprint adaptor for the alternate QFP44 package is available as a separate item.
The resulting emulation system allows complete control and tracing of execution of a user's program, and access to all registers and memory spaces of the target microcontroller, without consuming any device resources or introducing wait-states or other non-standard behaviour.
Features include:
- transparent real-time in-circuit emulation with execution trace.
- flexible motherboard + daughterboard + adaptor architecture.
- sophisticated Windows debugger supporting all popular compilers.
- execution up to 15 MHz (6-clock) at a 5V supply (see note)
- 64k bytes of emulation memory for user code.
- 28k x 32 bits real-time trace buffer with 12 digital input channels.
- programmable PLL-synthesised clock frequency.
- multiple breakpoint sources, unlimited execution address breakpoints.
- trigger output for synchronising external equipment with execution.
- footprint adapters for various device packages.
NOTE: Execution speed is conservatively rated - the PDB591-551 daughterboard is tested during production at higher speeds and will typically run at 17 MHz.
The PDB591-551 daughterboard can be used with both PDS51-Mk2A and PDS51-Mk2 motherboards. It is not compatible with the earlier PDS51 motherboard since this lacks support for the PLL-synthesised clock feature.
In order to emulate the P8xC551 and P8xC553 devices an alternate bondout (PDB553) device is required. Since Philips has now discontinued production of both these devices, this bondout is not included with the PDB591-551 daughterboard. Please contact us if you need this alternate bondout.
