From 1 January 2011 Acqura Systems will no longer supply Philips microcontroller development products. We would like to thank our customers for their support over the last eight years.

	PDS51E PDS51E Emulation System Motherboard Supported Devices P87C51MB2, P87C51MC2, P89C669 Related Products PDE51MX, PDE669, PDS900 Show all related products PDF Cost US $749.00 Quantity Required PDS51E is a high-performance universal motherboard which forms the basis for an affordable fully-featured in-circuit emulation system.  In combination with a growing range of companion daughterboards (PDE series - such as the PDE51MX daughterboard) and various footprint adaptors (each available separately) it provides development support for Philips latest 8051-derived microcontroller variants, and in particular those variants based on Philips MX (Memory eXtension) core or variants having a wide- and/or low supply voltage. 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 typically include: transparent real-time in-circuit emulation with wide/deep execution trace. flexible motherboard + daughterboard + adaptor architecture. sophisticated Windows debugger supporting all popular compilers. fast easy-to-install USB interface to host PC. 256k bytes of emulation memory for user code. 256k x 32 bits (or 128k x 64 bits) trace buffer with 12 digital input channels. programmable PLL-synthesised clock frequency (25kHz-100MHz, 0.1%). programmable power supply voltage (0-5.5V in 25mV steps). programmable current limit (0-250mA in 1mA steps). multiple breakpoint sources, unlimited execution address breakpoints. trigger output for synchronising external equipment with execution. completely 'soft' logic and firmware, free live updates via the web. NOTE: The actual programmed supply voltage is limited by the emulator to the range specified by the manufacturer for the target microcontroller device selected. The upper clock frequency is not limited but operation beyond the frequency range specified by the manufacturer is not guaranteed. The current limit applies to current supplied to the daughterboard from the programmable power supply. and (optionally) then to the user's target system. Some PDE-series daughterboards support neither the supply of power to the user's target, nor the current limit feature. In some cases the PDS51E system will also emulate older devices supported originally by the earlier PDS51-Mk2A system but with the advantage of increased performance and functionality. Except in these cases, the PDS51-Mk2A system should be used for emulation of older devices.
