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.

It is supplied with two bondouts each covering a different subset of Philips 8051-derived microcontroller range.  The PDB66x bondout provides emulation for the 8xC660, 662, 664, and 668 devices.  The PDB51Rx2 bondout provides emulation of the 8xC51/52/54/58, 8xC51FA/FB/FC, 8xC51RA/RB/RC/RD, 8xC51RA+/RB+/RC+/RD+, 8xC51RA2/RB2/RC2/RD2, 8XC51RA2H/RB2H/RC2H/RD2H, 8xC51RA2X2/RB2X2/RC2X2/RD2X2, 8xC60X2/61X2, and 8xC652/654 devices. Also supplied are footprint adaptors for DIP40 and PLCC44 device packages.  Footprint adaptors for other package styles are available as separate items. 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) or 30 MHz (12-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 PDB66x-Rx2 daughterboard is tested during production at higher speeds and will typically run at 17/34 (6/12-clock) MHz. The PDB66x-Rx2 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. The recently introduced P89C669 device is based on Philips MX (Memory eXtension) core and cannot be emulated by the PDB66x-Rx2 daughterboard. In order to emulate the P80C669 device you will instead need our PDS51E emulation system. This emulation system can also be used to support development using some of the devices supported by the PDB66x-Rx2 but with the advantage of increased performance and functionality.
