VG-PD6729, PCI-to-PC Card Controller

The Amphus VG-PD6729 PC Card controller is pin compatible and functionally equivalent to the Intel discontinued SPD6729 PC Card Controller.   The Amphus VG- PD6729 PCI-to-PC Card controller is a single- chip solution that provides direct connection to the PCI bus.   It is optimized for embedded applications where reduced form factor and low-power consumption are important design objectives.   Applications include customer premises equipment (CPE), routers, network switches, remote access servers, DSL access multiplexers (DSLAMs), and intelligent hand-held devices.   The PC Card interface can be used to support software updates, memory expansion, configuration storage and event logs, and both wireless and wire-line communications.

The Amphus VG-PD6729 accommodates various PC Card functions, including wireless, flash memory, and 10/100 Ethernet.   It is capable of controlling two fully independent PC Card sockets and is fully compatible with PCMCIA 2.1 and JEIDA 4.1. Fully buffered PCMCIA signals require no external logic to buffer incoming and outgoing signals, and allow power consumption to be controlled by limiting signal transitions on the PCMCIA bus.   The controller features energy efficient mixed voltage technology that can significantly reduce system power consumption. Suspend mode stops the internal clock, and automatic low-power dynamic mode stops transactions on the PCMCIA bus, stops internal clock distribution, and turns off internal circuitry.

Lead-Free version of VG-PD6729 is available now.   It is a Pin Compatible and Functional Equivalent to VG-PD6729.   It has the same silicon die as in VG-PD6729.   The only difference is the package material composition for the package used. Lead-content and other non-friendly environmental substances are completely removed from the package materials.   Because of the material differences, solder reflow profile for VG-PD6729-LF is slightly different from VG-PD6729.   The VG-PD6729-LF is fully compliant to RoHS environmental standards.
