SWCS037D – MAY 2008 – REVISED JUNE 2009
Introduction
The TPS65920/TPS65930 devices are power-management ICs for OMAP™ and other mobile
applications. The devices include power-management, a universal serial bus (USB) high-speed (HS)
transceiver, light-emitting diode (LED) drivers, an analog-to-digital converter (ADC), a real-time clock
(RTC), and embedded power control (EPC). In addition, the TPS65930 includes a full audio codec with
two digital-to-analog converters (DACs) and two ADCs to implement dual voice channels, and a stereo
downlink channel that can play all standard audio sample rates through a multiple format inter-integrated
sound (I2S™)/time division multiplexing (TDM) interface.
These optimized devices support the power and peripheral requirements of the OMAP application
processors. The power portion of the devices contains three buck converters, two controllable by a
dedicated SmartReflex™ class-3 interface, multiple low dropout (LDO) regulators, an EPC to manage the
power sequencing requirements of OMAP, and an RTC and backup module. The RTC can be powered by
a backup battery when the main supply is not present, and the devices include a coin-cell charger to
recharge the backup battery as needed.
The USB module provides a HS 2.0 OTG transceiver suitable for direct connection to the OMAP UTMI+
low pin interface (ULPI), with an integrated charge pump and full support for the carkit CEA-936A
specification. An ADC is provided for monitoring signals, such as supply voltage, entering the device, and
two additional external ADC inputs are provided for system use.
The devices provide driver circuitry to power two LED circuits that can illuminate a panel or provide user
indicators. The drivers also provide pulse width modulation (PWM) circuits to control the illumination levels
of the LEDs. A keypad interface implements a built-in scanning algorithm to decode hardware-based key
presses and reduce software use, with multiple additional general-purpose input/output devices (GPIOs)
that can be used as interrupts when configured as inputs.
This TPS65920/TPS65930 data manual presents the electrical and mechanical specifications for the
TPS65920 and TPS65930 devices. It covers the following topics:
• TPS65920/TPS65930 terminals: Assignment, multiplexing, electrical characteristics, and functional
description (see Section 2, Terminal Description)
• Electrical characteristic requirements: Maximum and recommended operating conditions, digital
input/output (I/O) characteristics (see Section 3, Electrical Characteristics)
• Power module: Power provider, power references, power control, power consumption, and power
management, with the on and off sequence (see Section 4, Power Module)
• RTC and EPC (see Section 5, Real-Time Clock and Embedded Power Controller)
• Audio/voice module (TPS65930 device only): Electrical characteristics and application schematics for

(1) This column provides the connection when the associated feature is not used or not connected. When there is a pin muxing, not all
functions on the muxed pin are used. But even if a function is not used, the Default Configuration After Reset Released column still
applies.
Connection criteria:
– Analog pins:
– For input: GND
– For output: Floating (except VPRECH is connected to GND)
– For I/O if input by default: GND (except for audio features input: capacitor to ground with a 100-nF typical value capacitor)
– Digital pins:
– For input: GND (except keypad and STP are left floating)
– For input and pullup: Floating
– For output: Floating
– For I/O and pullup: Floating
N/A (not applicable): When the associated feature is mandatory for correct functioning of the TPS65920/TPS65930 device
(2) The signals VPRECH, VBATS, and VCCS must be connected to each other and to the CPRECH capacitor to GND.
(3) Signal not functional indicates that no signal is presented on the pad after a release reset.

VDD1 dc-dc Regulator
4.1.1.1 VDD1 dc-dc Regulator Characteristics
The VDD1 dc-dc regulator is a stepdown dc-dc converter with a configurable output voltage. The
programming of the output voltage and the characteristics of the dc-dc converter are
SmartReflex-compatible. The regulator can be put in sleep mode to reduce its leakage (PFM) or in
power-down mode when it is not in use. Table 4-2 describes the regulator characteristics.

VIO dc-dc Regulator
4.1.3.1 VIO dc-dc Regulator Characteristics
The I/O and memory dc-dc regulator is a 600-mA stepdown dc-dc converter (internal FET) with two output
voltage settings. It supplies the memories and all I/O ports in the application and is one of the first power
providers to switch on in the power-up sequence. This dc-dc regulator can be placed in sleep or
power-down mode; however, care must be taken in the sequencing of this power provider, because
numerous ESD blocks are connected to this supply. Table 4-4 describes the regulator characteristics.

VMMC1 LDO Regulator
The VMMC1 LDO regulator is a programmable linear voltage converter that powers the multimedia card
(MMC) slot. It includes a discharge resistor and overcurrent protection (short-circuit). This LDO regulator
can also be turned off automatically when MMC card extraction is detected. The VMMC1 LDO can be
powered through an independent supply other than the battery; for example, a charge pump. In this case,
the input from the VMMC1 LDO can be higher than the battery voltage. Table 4-7 describes the regulator
characteristics.

Charge Pump
The charge pump generates a 4.8-V (nominal) power supply voltage from the battery to the VBUS pin.
The input voltage range is 2.7 to 4.5 V for the battery voltage. The charge pump operating frequency is
1 MHz.
The charge pump tolerates 7 V on VBUS when it is in power-down mode. The charge pump integrates a
short-circuit current limitation at 450 mA. Table 4-10 lists the charge pump output load conditions.

4.1.10 USB LDO Short-Circuit Protection Scheme
The short-circuit current for the LDOs and dc-dcs in the TPS65920 and TPS65930 devices is
approximately twice the maximum load current. When the output of the block is shorted to ground, the
power dissipation can exceed the 1.2-W requirement if no action is taken. A short-circuit protection
scheme is included in the TPS65920 and TPS65930 devices to ensure that if the output of an LDO or
dc-dc is short-circuited, the power dissipation does not exceed the 1.2-W level.
The three USB LDOs, VRUSB3V1, VRUSB1V8, and VRUSB1V5, are included in this short-circuit
protection scheme, which monitors the LDO output voltage at a frequency of 1 Hz and generates an
interrupt (sc_it) when a short-circuit is detected.
The scheme compares the LDO output voltage to a reference voltage and detects a short-circuit if the
LDO voltage drops below this reference value (0.5 or 0.75 V programmable). In the case of the
VRUSB3V1 and VRUSB1V8 LDOs, the reference is compared with a divided down voltage (1.5 V typical).
If a short-circuit is detected on VRUSB3V1, the power subchip FSM switches this LDO to sleep mode.
If a short-circuit is detected on VRUSB1V8 or VRUSB1V5, the power subchip FSM switches off the
relevant LDO.

Power References
The bandgap voltage reference is filtered (resistance/capacitance [RC] filter) using an external capacitor
connected across the VREF output and an analog ground (REFGND). The VREF voltage is scaled,
distributed, and buffered in the device. The bandgap is started in fast mode (not filtered), and is set
automatically by the power state-machine in slow mode (filtered, less noisy) when required.

Backup Battery Charger
If the backup battery is rechargeable, it can be recharged from the main battery. A programmable voltage
regulator powered by the main battery allows recharging of the backup battery. The backup battery charge
must be enabled using a control bit register. Recharging starts when two conditions are met:
• Main battery voltage > backup battery voltage
• Main battery > 3.2 V
The comparators of the backup battery system (BBS) give the two thresholds of the backup battery charge
startup. The programmed voltage for the charger gives the end-of-charge threshold. The programmed
current for the charger gives the charge current.
Overcharging is prevented by measurement of the backup battery voltage through the GP ADC.
Table 4-12 lists the characteristics of the backup battery charger.

VRRTC LDO Regulator
The VRRTC voltage regulator is a programmable, low dropout, linear voltage regulator supplying (1.5 V)
the embedded real-time clock (32.768-kHz oscillator) and dedicated I/Os of the digital host counterpart.
The VRRTC regulator is also the supply voltage of the power-management digital state-machine. The
VRRTC regulator is supplied from the UPR line, switched on by the main or backup battery, depending on
the system state. The VRRTC output is present as long as a valid energy source is present. The VRRTC
line is supplied by an LDO when VBAT > 2.7, and a clamp circuit when in backup mode. Table 4-14
describes the regulator characteristics.

Real-Time Clock and Embedded Power Controller
The TPS65930 and TPS65920 devices contain an RTC to provide clock and timekeeping functions and an
EPC to provide battery supervision and control.
5.1
RTC
The RTC provides the following basic functions:
• Time information (seconds/minutes/hours) directly in binary-coded decimal (BCD) code
• Calendar information (day/month/year/day of the week) directly in BCD code
• Interrupt generation periodically (1 second/1 minute/1 hour/1 day) or at a precise time (alarm function)
• 32-kHz oscillator drift compensation and time correction
• Alarm-triggered system wake-up event
5.1.1
Backup Battery
The TPS65030 and TPS65920 devicesdevice implement a backup mode in which a backup battery can
keep the RTC running to maintain clock and time information even if the main supply is not present. If the
backup battery is rechargeable, the device also provides a backup battery charger so it can be recharged
when the main battery supply is present.
The backup domain powers the following:
• Internal 32.768-kHz crystal oscillator
• RTC
• Eight general-purpose (GP) storage registers
• Backup domain low-power regulator (VBRTC)
5.2
EPC
The EPC provides five system states for optimal power use by the system, as listed in Table 5-1.
Table 5-1. System States
System State
NO SUPPLY
Description
The system is not powered by any battery.
BACKUP
The system is powered only with the backup battery and maintains
only the VBRTC supply.
WAIT-ON
The system is powered by the main battery and maintains only the
VRRTC supply. It can accept switch-on requests.
ACTIVE
The system is powered by the main battery; all supplies can be
enabled with full current capability.
SLEEP
The main battery powers the system; selected supplies are enabled,
but in low consumption mode.
Three categories of events can trigger state transitions:
• Hardware events: Supply/battery insertion, wake-up requests, USB plug, and RTC alarm
• Software events: Switch-off commands, switch-on commands, and sleep on commands
• Monitoring events: Supply/battery level check, main battery removal, main battery fail, and thermal
shutdown

FS is the sampling frequency (8, 11.025, 12, 16, 22.05, 24, 32, 44.1, or 48 kHz).
6.1.5
Boost Stage
The boost effect adds emphasis to low frequencies. It compensates for a HPF created by the capacitor
resistor (CR) filter of the headset (in ac-coupling configuration).
There are four modes. Three effects are available, with slightly different frequency responses, and the
fourth setting disables the boost effect:
• Boost effect 1
• Boost effect 2
• Boost effect 3
• Flat equalization: The boost effect is in bypass mode.
NOTE
Boost effect modes are defined in Table 6-5.
Table 6-5 and Table 6-6 include the typical values according to the frequency response versus input
frequency and FS frequency.

Audio Uplink (TX) Module
The audio uplink path includes two input amplification stages:
• MIC_MAIN_P, MIC_MAIN_M (differential main handset input)
• AUXR (common terminal: single-ended auxiliary)
NOTE
If two audio inputs are needed, and mic bias is not needed, the AUXR input can be used
with MIC_MAIN to provide the two inputs.
6.2.1
Microphone Bias Module
A bias generator provides an external voltage of 2.2 V to bias the analog microphones (MICBIAS1
terminal). The typical output current is 1 mA.

NOTE
To improve the rejection, ensure that MICBIAS_GND is as clean as possible. This ground
must be shared with AGND of the TPS65920 or TPS65930 device and must not share
with AVSS4, which is the ground used by RX class AB output stages.
In differential mode, adding a low-pass filter (made by RSB and CB) is highly
recommended if coupling between RX output stages and the microphone is too high (and
not enough attenuation by the echo cancellation algorithm). The coupling can come from:
• The internal TPS65920/TPS65930 coupling between MICBIAS.OUT voltage and RX
output stages
• Coupling noise between MICBIAS.GND and AVSS4
In pseudodifferential mode, the dynamic resistance of the microphone improves the
rejection versus MICBIAS.OUT:
PSRR = 20*log((RB + RDyn_mic)/RB).
6.2.1.2 Silicon Microphone Module Characteristics
Based on silicon micro-electrical-mechanical system (MEMS) technology, the new microphone achieves
the same acoustic and electrical properties as conventional microphones, but is more rugged and exhibits
higher heat resistance. These properties offer designers of a wide range of products greater flexibility and
new opportunities to integrate microphones.

The silicon microphone is the integration of mechanical elements and electronics on a common silicon
substrate through microfabrication technology.
The complementary metal oxide semiconductor (CMOS) MEMS microphone is more like an analog IC
than a classical microphone, or electric condenser microphone (ECM). It is powered as an IC with a direct
connection to the power supply. The on-chip isolation between the power input and the rest of the system
adds power supply rejection (PSR) to the component. This makes the CMOS MEMS microphone
inherently more immune to power supply noise than an ECM and eliminates the need for additional
filtering circuitry to keep the power supply line clean.

PHY Electrical Characteristics
The PHY is the physical signaling layer of the USB 2.0. It contains the drivers and receivers for physical
data and protocol signaling on the DP and DM lines.
The PHY interfaces with the USB controller through the UTMI.
The transmitters and receivers in the PHY are of two main classes:
• FS and LS transceivers (legacy USB1.x transceivers)
• HS transceivers
To bias the transistors and run the logic, the PHY also contains reference generation circuitry which
consists of:
• A DPLL that does a frequency multiplication to achieve the 480-MHz low-jitter lock necessary for USB,
and the clock required for the switched capacitor resistance block
• A switched capacitor resistance block that replicates an external resistor on chip
Built-in pullup and pulldown resistors are used as part of the protocol signaling.
The PHY also contains circuitry that protects it from an accidental 5-V short on the DP and DM lines and
from 8-kV IEC ESD strikes.
7.1.4.1 HS Differential Receiver
The HS receiver consists of the following blocks:
• A differential input comparator to receive the serial data
• A squelch detector to qualify the received data
• An oversampler-based clock data recovery scheme followed by a nonreturn to zero inverted (NRZI)
decoder, bit unstuffing, and serial-to-parallel converter to generate the UTMI DATAOUT
Table 7-5 lists the characteristics of the HS differential receiver.

7.1.4.2 HS Differential Transmitter
The HS transmitter is always operated on the UTMI parallel interface. The parallel data on the interface is
serialized, bit stuffed, NRZI encoded, and transmitted as a dc output current on DP or DM, depending on
the data. Each line has an effective 22.5-Ω load to ground, which generates the voltage levels for
signaling.
A disconnect detector is also part of the HS transmitter. A disconnect on the far end of the cable causes
the impedance seen by the transmitter to double, thereby doubling the differential amplitude seen on the
DP/DM lines.

General Description
www.ti.com
The TPS65920/TPS65930 device provides the MADC resource to the host processors in the system
(hardware and software conversion modes).
The MADC generates interrupt signals to the host processors. Interrupts are handled primarily by the
MADC internal secondary interrupt handler and secondly at the upper level (outside the MADC) by the
TPS65920/TPS65930 interrupt primary handler.

When a key button of the keyboard matrix is pressed, the corresponding row and column lines are shorted
together. To allow key press detection, all input pins (KBR) are pulled up to VCC and all output pins (KBC)
are driven to a low level.
Any action on a button generates an interrupt to the sequencer.
The decoding sequence is written to allow detection of simultaneous press actions on several key buttons.
The keyboard interface can be used with a smaller keyboard area than 6 × 6. To use a 3 × 3 keyboard,
KBR(4) and KBR(5) must be tied high to prevent any scanning process distribution.

clock provider in the system about the clock request and starts a timer (maximum of 5.2 ms using the
32.768-kHz clock). When the timer expires, the TPS65920/TPS65930 device opens a gated clock, the
timer automatically reloads the defined value, and a high-frequency output clock signal is available
through the HFCLKOUT pin. The output drive of HFCLKOUT is programmable (minimum load 10 pF,
maximum load 40 pF) and must be at 40 pF by default.
With a register setting, the mirroring of CLKEN can be enabled on CLKEN2. When this mirroring feature is
not enabled, CLKEN2 can be used as a general-purpose output controlled through I2C accesses.
CLKREQ, when enabled, has a weak pulldown resistor to support the wired-OR clock request.

The timer default value must be the worst case (10 ms) for the clock providers. For legacy or workaround
support, the NSLEEP1 and NSLEEP2 signals can also be used as a clock request even if it is not their
primary goal. By default, this feature is disabled and must be enabled individually by setting the register

When the external clock signal is present on the HFCLKIN ball, it is possible to use this clock instead of
the internal RC oscillator and then synchronize the system on the same clock. The RC oscillator can then
go to idle mode.

11.2.3 32-kHz Input Clock
A 32.768-kHz input clock (often abbreviated to 32-kHz) generates the clocks for the RTC. It has a low-jitter
mode where the current consumption increases for lower jitter. It is possible to use the 32-kHz input clock
with an external crystal or clock source. Depending on the mode chosen, the 32K oscillator is configured
one of two ways:
• An external 32.768-kHz crystal through the 32KXIN/32KXOUT balls (see Figure 11-5). This
configuration is available only for master mode (for more information, see Section 12).
• An external square/sine wave of 32.768 kHz through 32KXIN with amplitude equal to 1.8 or 1.85 V
(see Figure 11-7, Figure 11-8, and Figure 11-9). This configuration is available for the master and
slave modes (for more information, see Section 12).

CXIN and CXOUT represent the total capacitance of the printed circuit board (PCB) and components,
excluding the crystal. Their values depend on the datasheet of the crystal, the internal capacitors, and the
parallel capacitor. The frequency of the oscillations depends on the value of the capacitors. The crystal
must be in the fundamental mode of operation and parallel resonant.
NOTE
For the values of CXIN and CXOUT, see Table 14-1.

11.2.3.2 External Clock Description
When an external 32K clock is used instead of a crystal, three configuration can be used:
• A square- or sine-wave input can be applied to the 32KXIN pin with amplitude of 1.85 or 1.8 V. The
32KXOUT pin can be driven to a dc value of the square- or sine-wave amplitude divided by 2. This
configuration, shown in Figure 11-7, is recommended if a large load is applied on the 32KXOUT pin.
• A square- or sine-wave input can be applied to the 32KXIN pin with amplitude of 1.85 or 1.8 V. The
32KXOUT pin can be left floating. This configuration, showed in Figure 11-8, is used if no charge is
applied on the 32KXOUT pin.
• The oscillator is in bypass mode and a square-wave input can be applied to the 32KXIN pin with
amplitude of 1.8 V. The 32KXOUT pin can be left floating. This configuration, shown in Figure 11-9, is
used if the oscillator is in bypass mode.

Figure 11-11. 32.768-kHz Clock Output Block Diagram
The TPS65920/TPS65930 device has an internal 32.768-kHz oscillator connected to an external
32.768-kHz crystal through the 32KXIN/32KXOUT balls or an external digital 32.768-kHz clock through the
32KXIN input (see Figure 11-11). The TPS65920/TPS65930 device also generates a 32.768-kHz digital
clock through the 32KCLKOUT pin and can broadcast it externally to the application processor or any
other devices. The 32KCLKOUT clock is broadcast by default in TPS65920/TPS65930 active mode, but
can be disabled if it is not used.
The 32.768-kHz clock (or signal) is also used to clock the RTC embedded in the TPS65920/TPS65930
device. The RTC is not enabled by default. The host processor must set the correct date and time and
enable the RTC functionality.
The 32KCLKOUT output buffer can drive several devices (up to 40-pF load). At startup, 32KCLKOUT
must be stabilized (frequency/duty cycle) before the signal output. Depending on the startup conditions,
this can delay the startup sequence.
Table 11-9 lists the electrical characteristics of the 32KCLKOUT output clock.

12.3 I2C Timing
The TPS65920/TPS65930 device provides two I2C HS slave interfaces (one for general-purpose and one
for SmartReflex). These interfaces support standard mode (100 Kbps), fast mode (400 Kbps), and HS
mode (3.4 Mbps). The general-purpose I2C module embeds four slave hard-coded addresses (ID1 = 48h,
ID2 = 49h, ID3 = 4Ah, and ID4 = 4Bh). The SmartReflex I2C module uses one slave hard-coded address
(ID5). The master mode is not supported.

12.4 Audio Interface: TDM/I2S Protocol
The TPS65920/TPS65930 device acts as a master for the TDM and I2S interfaces or as a slave for only
the I2S interface. If the TPS65920/TPS65930 device is the master, it must provide the frame
synchronization (TDM/I2S_SYNC) and bit clock (TDM/I2S_CLK) to the host processor. If it is the slave,
the TPS65920/TPS65930 device receives frame synchronization and the bit clock.
The TPS65920/TPS65930 device supports the I2S, TDM, left-justified, and right-justified data formats, but
does not support TDM slave mode.

12.5 JTAG Interfaces
The TPS65920/TPS65930 device JTAG TAP controller handles standard IEEE JTAG interfaces. This
section describes the timing requirements for the tools used to test TPS65920/TPS65930 device power
management.
The JTAG/TAP module provides a JTAG interface according to IEEE Std1149.1a. This interface uses the
four I/O pins TMS, TCK, TDI, and TDO. The TMS, TCK, and TDI inputs contain a pullup device, which
makes their state high when they are not driven. The output TDO is a 3-state output, which is high
impedance except when data are shifted between TDI and TDO.
• TCK is the test clock signal.
• TMS is the test mode select signal.
• TDI is the scan path input.
• TDO is the scan path output.
TMS and TDO are multiplexed at the top level with the GPIO0 and GPIO1 pins. The dedicated external
TEST pin switches from functional mode (GPIO0/GPIO1) to JTAG mode (TMS/TDO). The JTAG
operations are controlled by a state-machine that follows the IEEE Std1149.1a state diagram. This
state-machine is reset by the TPS65920/TPS65930 internal power-on reset (POR). A test mode is
selected by writing a 6-bit word (instruction) into the instruction register and then accessing the related
data register.
Table 12-9 and Table 12-10 assume testing over the recommended operating conditions (see
Figure 12-5).

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
