ISP1362
Single-chip USB OTG Controller
10. On-The-Go (OTG) Controller
10.1 Introduction
OTG is a supplement to the Hi-Speed USB (USB 2.0) specication that augments existing
USB peripherals by adding to these peripherals limited host capability to support other
targeted USB peripherals. It is primarily targeted at portable devices because it addresses
concerns related to such devices, such as a small connector and low power. Non-portable
devices (even standard hosts), nevertheless, can also benet from OTG features.
The ISP1362 OTG Controller is designed to perform all the tasks specied in the OTG
supplement. It supports Host Negotiation Protocol (HNP) and Session Request Protocol
(SRP) for dual-role devices. The ISP1362 uses software implementation of HNP and SRP
for maximum exibility. A set of OTG registers provides the control and status monitoring
capabilities to support software HNP or SRP.
Besides the normal USB transceiver, timers and analog components required by OTG are
also integrated on-chip. The analog components include:
Built-in 3.3 V-to-5 V charge pump
Voltage comparators
Pull-up or pull-down resistors on data lines
Charge or discharge resistors for VBUS
10.2 Dual-role device
When port 1 of the ISP1362 is congured in OTG mode, it can be used as an OTG
dual-role device. A dual-role device is a USB device that can function either as a host or
as a peripheral. As a host, the ISP1362 can support all four types of transfers (control,
bulk, isochronous and interrupt) at full-speed or low-speed. As a peripheral, the ISP1362
can support two control endpoints and up to 14 congurable endpoints, which can be
programmed to any of the four transfer types.
The default role of the ISP1362 is controlled by the ID pin, which in turn is controlled by
the type of plug connected to the mini-AB receptacle. If ID = LOW (mini-A plug
connected), it becomes an A-device, which is a host by default. If ID = HIGH (mini-B plug
connected), it becomes a B-device, which is a peripheral by default.
Both the A-device and the B-device work on a session base. A session is dened as the
period of time in which devices exchange data. A session starts when VBUS is driven and
ends when VBUS is turned off. Both the A-device and the B-device may start a session.
During a session, the role of the host can be transferred back and forth between the
A-device and the B-device any number of times by using HNP.
If the A-device wants to start a session, it turns on VBUS by enabling the charge pump. The
B-device detects that VBUS has risen above the B_SESS_VLD level and assumes the role
of a peripheral, asserting its pull-up resistor on the DP line. The A-device detects the
remote pull-up resistor and assumes the role of a host. Then, the A-device can
communicate with the B-device as long as it wishes. When the A-device nishes
communicating with the B-device, the A-device turns-off VBUS and both the devices nally
