The
μ
PD72012 is a dedicated LSI for a HUB connected to a universal serial bus (USB) system.
It is an upgrade of NEC’s
μ
PD72011. It complies with USB specification revision 1.1.
By putting descriptors into ROM, information such as a user’s vendor ID can be implemented in the chip.
FEATURES
{
Compliant with Chapter 11 (HUB Specifications) of USB Specification 1.1.
{
Descriptors into ROM
The user can customize the vendor ID and product ID by using Mask ROM option.
{
Supports 5 kinds of string descriptors (for Mask ROM code product only)
{
On-chip sequencer
There is an on-chip descriptor and request response sequencer. External initial setup and control is not needed
and HUB functions can be realized using only the
μ
PD72012.
{
Downstream ports
Four or five ports can be selected using a pin function.
{
Power modes
Bus power or self-power can be selected using a pin function (an external power control circuit is required).
{
Corresponds to standard descriptor products
Two kinds of standard ROM code products are provided. Standard and HUB class descriptors are on-chip in
the
μ
PD72012.
ROM code: 003 (individual overcurrent monitoring type Generic HUB)
ROM code: 004 (collective overcurrent monitoring type Generic HUB)
{
Supports two kinds of clock input
48 MHz oscillator input or a 4 MHz crystal resonator can be supported
{
Power control
Port power control and overcurrent detection functions are on-chip. Individual port control or collective control
can be selected for these.
