CD covers full range of microcontrollers and tools
Available now free from Sunrise Electronics is a new CD featuring all the latest information on NEC's extensive range of microcontroller families and development tools.
It complies with the Universal Serial Bus Specification Revision 2.0 and works up to 480Mbit/s.
It has low power and high performance to enable bus powered USB device configuration capability and high bandwidth.
The uPD720130 integrates CISC processor, IDE controller, endpoint controller (EPC), RAM, serial interface engine (SIE), on-chip ROM and USB 2.0 transceiver into a single chip.
The USB 2.0 protocol and class specific protocol (bulk only protocol) are handled by the USB 2.0 transceiver, SIE and EPC.
The transport layer is performed by the on-chip V30MZ CISC processor.
An on-chip ROM contains the operational firmware.
NEC's uPD720130 is compliant with Universal Serial Bus Specification Revision 2.0 and with ATA/ATAPI-6 (with support for LBA48, and Ultra DMA/66 Mode 0-4).
It supports USB 2.0 specifications for high-speed bus-powered device capability.
Each device implements one USB 2.0 high-/full-speed transceiver/receiver, including a USB 2.0 high-/full-speed packet protocol sequencer (serial interface engine) with automatic chirp assertion and high-/full-speed mode change.
It offers USB reset, suspend and resume signalling detection and supports remote wakeup functionality.
It also supports power control functionality for ATAPI devices such as CD-ROM.
This device complements NEC's new upgraded host controller, the uPD720101, the world's first EHCI 1.0 host controller.
This five-port USB 2.0 host controller is fully compliant with PCI 2.2 (32bit 33MHz) and PCI Power Management 1.1.
Operating from either 3.3 or 5V power supplies (5V PCI signal tolerant) this device has extremely low power consumption at only 220mA.
It is offered in a choice of two low pin count packages, a 144-pin LQFP and 144-pin plastic BGA outlines, sampling now for volume production in September 2002.
