The MAX3420EETG+ is an advanced USB peripheral controller integrated circuit (IC) designed for low-power embedded applications requiring a USB peripheral/host interface. The MAX3420EETG+ includes a USB transceiver, contacts controllers in a 20-pin Thin TSSOP (TSSOP-20) package, and is ideal for integrating a USB authoring interface into consumer products. With the MAX3420EETG+, designers can add an integrated, low-power USB interface to peripheral ports in consumer products such as digital media players, printers, scanners, cameras, and cell phones.

The MAX3420EETG+ features two serial communications ports: an Enhanced Universal Serial Bus (USB) port and an I/O port. The USB port supports both full- and low-speed USB and is intended for connecting to external USB hosts or peripherals, while the I/O port provides flexible interface support for microcontroller-based applications. The MAX3420EETG+ also includes on-chip pullup resistor regulators and wake-up circuits, enabling the device to operate under low-power conditions.

The MAX3420EETG+ features an 8-bit embedded microprocessor that executes external firmware instructions. The internal microprocessor contains an address bus, data bus and program counter, allowing embedded firmware to be used to configure, control and monitor the MAX3420EETG+ operations. The MAX3420EETG+ can be set up to autonomously control and manage USB transactions in a variety of applications, including USB host and device communications, device enumeration and configuration, and peripheral support for USB bulk, isochronous and control transfer applications. The MAX3420EETG+ also includes programmable USB interrupt, suspend and reset pins.

The MAX3420EETG+ is designed for low-power applications that require a low-cost and efficient USB interface solution. Its low operating voltage (5V maximum on the I/O port and 3.3V maximum on the USB port) and wide operating temperature range (-40 to +85 degrees Celsius) make it an ideal solution for embedded applications. The internal microprocessor can be programmed to autonomously manage USB transactions, allowing embedded firmware code to configure, control and monitor the operations of the MAX3420EETG+. This allows the device to operate under low-power conditions while meeting the requirements of USB peripherals or hosts.

The MAX3420EETG+ is designed with several low-power features that make it suitable for use in powering a wide range of embedded applications. The on-chip pullup regulators provide stable power for the Main and I/O ports, allowing for low-power operation of the device. In addition, the MAX3420EETG+ also includes programmable wake-up and reset pins that allow the device to remain in low-power mode until a specified event occurs.

The MAX3420EETG+ is ideal for integrated, low-power USB interfaces for applications such as digital media players, printers, scanners, cameras, and cell phones. Its 8-bit embedded microprocessor can be programmed to autonomously manage USB transactions, allowing the device to meet the requirements of USB hosts and peripherals without the need for external hardware or firmware. The on-chip low-power features make the device ideal for powering embedded devices with long periods of idle or low power states, while the wide operating temperature range allows the device to operate in extreme environments.
