This restricts signal drive to only 3.3V level signals. Disconnects internal 3.3V regulator connection to VCCIO. This mode allows for the supply of 1.8V-3.3V power from an external power supply, thus allows the JP1 Opened processing of signals with logic levels between 1.8V and 3.3V. VCCIO can be adjusted to match the interface requirements of external circuitry. Table 5.1 – Jumper JP1 Pin Description NonDefault Jumper No. Setting Status Description JP2 Shorted Default Connects VBUS to VCC. This mode is known as “USB-Powered” mode. NonDisconnects VBUS to VCC. This allows the supply of power from an external power Default supply. This mode is known as “Self-Powered” mode. Table 5.2 – Jumper JP2 Pin Description JP2 Opened Note: There should never be more than one power output supplied to the same net. If JP2 is fitted when an external power supply is applied a direct short between two power supplies will be formed, this can result in damage to the UMFT221XE module and the target circuit. 7 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 Clearance No.: FTDI# 293 5.2 Bus Powered Configuration GND Alternative connection VCCIO VCC 3V3OUT VBUS Alternative connection Current Flow GND Self-Sourced 3V3 TTL Mode Jumper JP1 - Closed Bus Powered Mode Jumper JP2 - Closed Figure 5.1 – Bus Powered Configuration A bus powered configuration draws its power from the USB host/hub. The UMFT221XE is configured by default to be in bus powered mode. Figure 5.1 illustrates the UMFT221XE 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 FT221X power input (VCC) +3.3V power is sourced from the FT221X‟s voltage regulator output and is connected to the FT221X IO port‟s power input (VCCIO). Interfacing the UMFT221XE 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 from the USB bus (either the 5V from the USB pin, or 3.3V from the 3V3OUT pin). 8 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 Clearance No.: FTDI# 293 5.3 Self Powered Configuration Vcc = 1.8V – 3.3V Vcc = 5V VIO IO0 SCLK SS# IO0 SCLK Optionial IO1 SS# Optionial IO2 Optionial IO3 MISO Optionial IO4 Optionial IO5 Optionial IO6 MISO MCU GND Optionial IO7 VCCIO VCC 3V3OUT VBUS GND Variable TTL Mode Jumper JP1 - Open Self Power Mode Jumper JP2 - Open Figure 5.2 – Self-Powered Configuration A self-powered configuration operates on the principle of drawing power 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 UMFT221XE in a typical USB self-powered configuration. 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 UMFT221XE 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 FT221X 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 UMFT221XE will override the effect of this voltage divider. When the FT221X 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 FT221X in FT1248 1-bit mode is illustrated in Figure 5.2. This example shows the wire configuration of the transfer and handshake lines. This example also illustrates that a voltage other than 3.3V can be supplied to the FT221X‟s IO port, this feature is described further and for bus powered mode in Section 5.5. Alternatively both the FT221X‟s IO port and MCU can be powered from the 3V3OUT pin; this approach is described in Section 5.4. 9 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 Clearance No.: FTDI# 293 5.4 USB Bus Powered with Power Switching Configuration VCC IO0 SCLK SS# IO0 SCLK Optionial IO1 SS# Optionial IO2 Optionial IO3 MISO MCU 0.1uF 10K PWREN# 0.1uF g Soft Start Circuit CBUS3 Optionial IO4 Optionial IO5 Optionial IO6 MISO P-Channel Power MOSFET s d 1K GND Optionial IO7 VCCIO VCC 3V3OUT VBUS GND Bus Powered Mode Self-Sorced 3.3V TTL Mode Jumper JP1 - Closed Jumper JP2 - Closed Figure 5.3 – Bus Powered with Power Switching Configuration USB bus powered mode is introduced in Section5.3 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 when in USB suspend mode. The PWREN# CBUS function can be used to remove power from external circuitry whenever the FT221X is not enumerated. (Note: It is impossible to be in suspended mode when PWREN# is low.) To implement a power switch using PWREN#, 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 FT221X without breaking USB compliancy. In this setup it is important that the VCCIO is not sourced from the drain of this MOSFET, this is because the power used to drive the gate of this transistor is sourced from VCCIO. VCCIO should be connected directly to 3V3OUT for this setup to function effectively. It is also important that the external logic must and IO core of the FT221X must not draw more that 50mA, this is because the current limit of the internal 3.3V regulator is 50mA. 10 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 Clearance No.: FTDI# 293 5.5 Variable IO Voltage Supply Vcc = 1.8V – 3.3V IO0 SCLK SS# MISO MCU IO0 SCLK Optional IO1 Optional IO2 Optional IO3 Optional IO4 Optional IO5 Optional IO6 SS# MISO GND Optional IO7 VCCIO VCC 3V3OUT VBUS GND Jumper JP1 - Open Jumper JP2 - Closed Figure 5.4 – USB Bus Powered 3.3V Logic Drive The FT221X 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 FT221X 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 with a voltage level that is equal to the level of the signals it is processing. Since the FT221X‟s embedded voltage regulator only outputs 3V3 the IO ports will need to be powered from another 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 selfpowered 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. 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 FT221X 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. 11 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 Clearance No.: FTDI# 293 5.6 3.3V Voltage Supply Vcc = 3.3V Vcc = 3.3V IO0 SCLK SS# MISO MCU IO0 SCLK Optional IO1 Optional IO2 Optional IO3 Optional IO4 Optional IO5 Optional IO6 SS# MISO GND Optional IO7 VCCIO VCC 3V3OUT VBUS GND Jumper JP1 - Closed Jumper JP2 - Open Figure 5.5 – USB Self Powered 3.3V Logic Drive The FT221X can be powered from a single 3.3V supply. This feature is an alternative to having the FT221X powered at 5V in standard self-powered configuration. The 3.3V Self Powered configuration is illustrated in Figure 5.5. Note that the 3.3V net is connected to VCC, VCCIO and 3V3OUT. 5.7 Configuring the MTP ROM The FT221X 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. 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. 12 Copyright © 2012 Future Technology Devices International Limited UMFT221XE Version 1.0 Document Reference No.: FT_000651 6 Clearance No.: FTDI# Module Dimensions 2.54 32.5 15.24 19.24 2.3 1.8 34.5 5.8 1.6 9.2 Figure 6.1 – UMFT221XE Module Dimensions All dimensions are given in millimetres.
