DZPD6710VCB

Product Summary

The DZPD6710VCB is a single-chip PC Card (PCMCIA) controller solution capable of controlling one PC Card sockets. The chip is compliant with PC Card Standard, PCMCIA 2.1, and JEIDA 4.1 and is optimized for use in embedded applications and notebook/handheld/mobile computer systems where reduced form factor and low power consumption are critical design objectives. With the DZPD6710VCB, a complete PC Card solution with power-control logic can occupy less than 1.5 square inches (excluding the socket connector). The chip employs energy-efficient mixed-voltage technology that can reduce system power consumption by over 50 percent. The chip DZPD6710VCB also provides: a Low-Power Dynamic mode, which automatically stops the internal clock during periods of card inactivity; a software-controlled Suspend mode, which dramatically reduces power by disabling most of the internal circuitry and stopping data transactions to the PC Cards; and a hardware-controlled Super Suspend mode, which reduces current to the μA range.
