UMFT201XE USB to I2C

Development Module

UMFT201XE is a USB to I²C DIP module with a 0.6” row pitch.

1.1 Features

1 Introduction

The UMFT201XE is a development module for

FTDI’s FT201XQ, one of the devices from FTDI’s

range of USB interface bridging integrated circuit

devices. FT201X is a USB to I²C interface with a

battery charger detection feature, which can

allow batteries to be charged with a higher

current from a dedicated charger port (without

the FT201X being enumerated). In addition,

asynchronous and synchronous bit bang interface

modes are available. The internally generated

clock (6MHz, 12MHz and 24MHz) can be brought

out on one of the CBUS pins to be usedto drive a

microprocessor or external logic.

The UMFT201XE utilises the FTDI FT201XQ; all

the features of the FT201X can be utilized with

the UMFT201XE. For a full list of the FT201X’s

features please see the FT201X datasheet which

can be found by clicking here.

In addition to the features listed in the FT201X

datasheet, the UMFT201XE has the following

features:



Small PCB assembly module designed to fit a

standard 15.24mm (0.6”) wide 16 pin DIP

socket. Pins are on a 2.54mm (0.1”) pitch.



On board USB ‘mini-B’ socket allows module

to be connected to a PC or USB host via a

standard A to mini-B USB cable.

The UMFT201XE is a module which is designed to

plug into a standard 0.6” wide 16 pin DIP socket.

All components used, including the FT201XQ are

Pb-free (RoHS compliant).

Functionally configurable using on board

jumpers. The default jumper setup enables

the module to function without peripheral

wires

or

application

board.

Other

configurations enable external power supply

options and variation of logic reference

levels.

Figure 5.1 – Bus Powered Configuration

A bus powered configuration draws its power from the USB host/hub. The UMFT201XE is configured by

default to be in bus powered mode.

Figure 5.1 illustrates the UMFT201XE module in a typical USB bus powered design configuration. By

default, 3V3OUT is connected to VCCIO, and VBUS is connected to VCC.

For a bus power configuration power is supplied from the USB VBUS:

+5V VBUS power is sourced from the USB bus and is connected to the FT201X power input (VCC)

+3.3V power is sourced fromthe FT201X’s voltage regulator output and is connected to the FT201X IO

port’s power input (VCCIO).

Interfacing the UMFT201XE module to a microcontroller (MCU), or other logic devices for bus powered

configuration is done in exactly the same way as a self-powered configuration (see Section 5.3), except

that it is possible for the MCU or external device to take its power supply fromthe USB bus (either the 5V

from the USB pin, or 3.3V from the 3V3OUT pin).

Figure 5.2 – Self-Powered Configuration

A self-powered configuration operates on the principle of drawingpower from an external power supply,

as oppose to drawing power from the USB host. In this configuration no current is drawn from the USB

bus.

Figure 5.2 illustrates the UMFT201XE in a typical USB self-poweredconfiguration. In this case the jumper

connection of JP1 is removed, which allows 5V power to be supplied to the module VCC pins from an

external source. VCCIO can to be powered from 3V3OUT or the VCC of an external source.

For a self-powered configuration, it is necessary to prevent current from flowing back to the USB data

lines when the connected USB host or hub has powered down. To carry out this function the UMFT201XE

uses an on-board voltage divider network connected to the USB power bus and RESET# pin. This

operates on the principle that when no power is supplied to the VBUS line, the FT201X will automatically

be held in reset by a weak pull-down, when power is applied the voltage divider will apply a weak 3.3V

pull-up. Driving a level to the RESET# pin of the UMFT201XE will override the effect of this voltage

divider. When the FT201X is in reset the USB DP signal pull-up resistor connected to the data lines is

disconnected and no current can flow down the USB lines.

An example of interfacing the FT201X with a microcontroller’s I²C interface is also illustrated in

Figure 5.2.

Figure 5.3 – Bus Powered with Power Switching Configuration

USB bus powered mode is introduced in Section 5.2. This section describes how to use bus-powered

mode with a power switch.

USB bus powered circuits are required by USB compliance standards to consume less than 2.5mA (and

less than 100mA when not enumerated and not suspended) when connected to a host or hub in USB

suspend mode. The PWREN# CBUS function can be used to remove power from external circuitry

whenever the FT201X is not enumerated.

To implement a power switch usingPWREN#, configure a P-Channel Power MOSFET to have a soft start

by fitting a 10K pull-up, a 1K series resistor and a 100nF cap as shown in

Figure 5.3.

Connecting the source of the P-Channel MOSFET to 3V3OUT instead of VBUS can allow external logic to

source 3.3V power from the FT201X without breaking USB compliancy. In this setup it is important that

the VCCIO is not sourced fromthe drain of this MOSFET, this is because the power usedto drive the gate

of this transistor is sourced fromVCCIO. VCCIO should be connecteddirectly to 3V3OUT for this setup to

function effectively. It is also important that the external logic must and IO core of the FT201X must not

draw more that 50mA, this is because the current limit of the internal 3.3V regulator is 50mA.

Figure 5.4 – USB Bus Powered 3.3V Logic Drive

The FT201X can process signals at CMOS/TTL logic levels in the range of 1.8V to 3.3V. This section

describes how to utilise this feature.

Figure 5.4 shows a configuration where the FT201X is interfaced to a device with IOs operating in the

range of 1.8V - 3.3V. The IO ports of this module need to be powered witha voltage level that is equal to

the level of the signals it is processing. Since the FT201X’s embedded voltage regulator only outputs 3V3

the IO ports will need to be powered fromanother power source when operating at voltage levels other

than 3.3V.

By default, a short is present between 3V3OUT (embedded voltage regulator) and VCCIO (IO port’s

power input) with the connection made by JP1. If an external power supply is used to power the IO ports

this jumper needs to be open.

The configuration described in this section can be implemented in either bus-powered mode or self-

powered mode.

Note 1: The CBUS and DBUS pins are 5V tolerant; however these signals cannot drive signals at 5V

TTL/CMOS. VCCIO is not 5V tolerant; applying 5V to VCCIO will damage the chip.

13

UMFT201XEDatasheet

Version 1.2

Document Reference No.: FT_000650 Clearance No.: FTDI#292

Note 2: If power is applied to VCCIO and no power is applied to VCC all IOs will be at an unknown state,

this however will not damage the chip. The FT201X also has protective circuitry to prevent the chip being

damaged by a voltage discrepancy between VCCIO and the level of the signal being processed.

Note 3: When using VCCIO less than 3V3 on a chip from FTDI’s X-chip range, it is recommended to use

pull up resistors (47K) to VCCIO on the data lines, all of the UMFT2xxXE devices include an on-board

pull-up for these lines.

The FT201X can be powered from a single 3.3V supply. This feature is an alternative to having the

FT201X powered at 5V in standard self-powered configuration.

The 3.3V Self Powered configuration is illustratedin Figure 5.5. Note that the 3.3V input is connected to

VCC, VCCIO and 3V3OUT.

5.7 Configuring the MTP ROM

The FT201X contains an embedded MTP ROM. This can be used to configure the functions of each CBUS

pin, the current drive on each signal pin, current limit for the USB bus and the other descriptors of the

device. For details on using the MTP ROM/EEPROM programming utility FT_PROG, please see the

FT_PROG User Guide.

UMFT201XEDatasheet

Version 1.2

When programming the MTP ROM please note:

i) One of the CBUS Pins can be configured as PWREN# in the internal MTP ROM. This can be used to

switch the power supply to the external circuitry.

ii) The Max Bus Power setting of the MTP ROM should specify the maximum current to be drawn from

the USB host/hub when enumerated. For high-powered USB devices the current limit when

enumerated is between 100mA and 500mA, for low-powered USB devices the current limit is

100mA.
