L6260 datasheet

 

Description :

The L6260 is single chip sensorless (DC) spindle motor and voice coil controllers including power stages suitable for use in small disk drives. These devices have a serial interface for a micro processor running up to 10 Mega bits per second. There are registers on chip to allow the setting of the desired spindle speed via the on chip Frequency Locked Loop (F.L.L.). No external components are required in the sensor-less operation as the control functions are integrated on chip (e.g. B.E.M.F. processing, digital masking, digital delay and sequencing).

Features

1. 5V OPERATION. REGISTER BASED ARCHITECTURE
2. MINIMUM EXTERNAL COMPONENTS
3. SLEEP AND IDLE MODES FOR LOW POWERCONSUMPTION
4. SELECTABLE GAINS FOR BOTH V.C.M. AND SPINDLE

Function

1. POWER UP SEQUENCING
2. POWER DOWN SEQUENCING
3. LOW VOLTAGE SENSE
4. ACTUATOR RETRACTION
5. DYNAMIC BRAKE
6. THERMAL SHUTDOWN

JMC261 datasheet

 

Description :

The JMC261 is a single-chip PCI-Express Fast Ethernet combo Card Reader Host controller. The  Fast Ethernet  function  is compliant  to  IEEE  802.3  Media  Access  Controller,  and  IEEE 802.3u 100BASE-TX/10BASE-T. The MAC supports IPV4, IPV6, TCP, UDP checksum, segmentation task-offload, priority encoding and IEEE802.1Q VLAN features. It also supports Receive Side Scaling (RSS) to balance the loading for received data processing across multiple CPUs.

Features

1. Compliant with PCI Express Base Spec. Revision 1.1
2. Integrated one-lane 2.5GHz PCI Express PHY
3. Support multi-entry MSI and multi-vector MSI-X.
4. Compliant with IEEE 802.3, IEEE 802.3u, and IEEE 802.3ab
5. Integrated 10/100Mbps transceiver
6. Support Auto Negotiation
7. Support Wake-on-LAN
