N.C. – No internal connection DESCRIPTION/ORDERING INFORMATION The TLC59116F is an I2C-bus controlled 16-channel LED driver optimized for red/green/blue/amber (RGBA) color mixing applications. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97 kHz with a duty cycle that is adjustable from 0% to 99.6% to allow the LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190 Hz and an adjustable frequency between 24 Hz to once every 10.73 seconds with a duty cycle that is adjustable from 0% to 99.6% that is used to either dim or blink all LEDs with the same value. Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values. The TLC59116F operates with a supply voltage range of 3 V to 5.5 V and the outputs are 17 V tolerant. LEDs can be directly connected to the TLC59116F device outputs. Software programmable LED group and three sub call I2C bus addresses allow all or defined groups of TLC59116F devices to respond to a common I2C bus address, allowing for example, all the same color LEDs to be turned on or off at the same time or marquee chasing effect, thus minimizing I2C bus commands. Four hardware address pins allow up to 14 devices on the same bus. The software reset (SWRST) call allows the master to perform a reset of the TLC59116F through the I2C bus, identical to the power-on reset (POR) that initializes the registers to their default state causing the outputs to be set high (LED off). This allows an easy and quick way to reconfigure all device registers to the same condition.

A master device must internally provide a hold time of at least 300 ns for the SDA signal (refer to the VIL of the SCL signal) in order to bridge the undefined region of SCL's falling edge. The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time (tf) for the SDA output stage is specified at 250 ns. This allows series protection resistors to be connected between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. Cb = total capacitance of one bus line in pF. Input filters on the SDA and SCL inputs suppress noise spikes less than 50 ns. Resetting the device while actively communicating on the bus may cause glitches or errant STOP conditions. Upon reset, the full delay will be the sum of tRESET and the RC time constant of the SDA bus.

Regular I2C Bus Slave Address The I2C bus slave address of the TLC59116F is shown in Figure 5. To conserve power, no internal pullup resistors are incorporated on the hardware-selectable address pins, and they must be pulled high or low. For buffer management purpose, a set of sector information data should be stored in a certain buffer. Slave Address 1 0 1 Fixed A3 A2 A1 A0 R/W Hardware Selectable Figure 5. Slave Address The last bit of the address byte defines the operation to be performed. When set to logic 1, a read is selected; a logic 0 selects a write operation. LED All-Call I2C Bus Address • • • Default power-up value (ALLCALLADR register): D0h or 1101 000 Programmable through I2C bus (volatile programming) At power-up, LED All Call I2C bus address is enabled. TLC59116F sends an ACK when D0h (R/W = 0) or D1h (R/W = 1) is sent by the master. See Register Definitions for more detail. NOTE The default LED all-call I2C bus address (D0h or 1101 000) must not be used as a regular I2C bus slave address since this address is enabled at power-up. All the TLC59116Fs on the I2C bus will acknowledge the address if sent by the I2C bus master. LED Sub-Call I2C Bus Address • • • • Three different I2C bus addresses can be used Default power-up values: – SUBADR1 register: D2h or 1101 001 – SUBADR2 register: D4h or 1101 010 – SUBADR3 register: D8h or 1101 100 Programmable through I2C bus (volatile programming) At power-up, sub-call I2C bus address is disabled. TLC59116F does not send an ACK when D2h (R/W = 0) or D3h (R/W = 1) or D4h (R/W = 0) or D5h (R/W = 1) or D8h (R/W = 0) or D9h (R/W = 1) is sent by the master. See Register Definitions for more detail. Copyright © 2009–2011, Texas Instruments Incorporated 9 TLC59116F SCLS714B – MARCH 2009 – REVISED JULY 2011 www.ti.com NOTE The default LED Sub Call I2C bus address may be used as a regular I2C bus slave address as long as the Sub Call addresses are disabled in MODE1 (default). Software Reset I2C Bus Address The address shown in Figure 6 is used when a reset of the TLC59116F needs to be performed by the master. The Software Reset address (SWRST Call) must be used with R/W = 0. If R/W = 1, the TLC59116F does not acknowledge the SWRST. See Register Definitions for more detail. R/W 1 1 0 1 0 1 1 0 The software reset I2C bus address is reserved address and cannot be use as regular I2C bus slave address or as an LED All-Call or LED Sub-Call address. Figure 6. Software Reset Address Control Register Following the successful acknowledgment of the slave address, LED All Call address or LED Sub Call address, the bus master will send a byte to the TLC59116F, which will be stored in the Control register. The lowest 5 bits are used as a pointer to determine which register will be accessed (D[4:0]). The highest three bits are used as Auto-Increment flag and Auto-Increment options (AI[2:0]). Auto-Increment Flag AI2 AI1 AI0 Register Address D4 D3 D2 D1 D0 Auto-Increment Options Figure 7. Control Register When the Auto-Increment flag is set (AI2 = logic 1), the five low order bits of the Control register are automatically incremented after a read or write. This allows the user to program the registers sequentially. Four different types of Auto-Increment are possible, depending on AI1 and AI0 values. Table 1. Auto-Increment Options (1) (1) 10 AI2 AI1 AI0 0 0 0 No auto-increment PIN DESCRIPTION 1 0 0 Auto-increment for all registers. D[4:0] roll over to '0 0000' after the last register (1 1011) is accessed. 1 0 1 Auto-increment for individual brightness registers only. D[4:0] roll over to '0 0010' after the last register (1 0001) is accessed. 1 1 0 Auto-increment for global control registers only. D[4:0] roll over to '1 0010' after the last register (1 0011) is accessed. 1 1 1 Auto-increment for individual and global control registers only. D[4:0] roll over to '0 0010' after the last register (1 0011) is accessed. Other combinations not shown in Table 1 (AI[2:0] = 001, 010 and 011) are reserved and must not be used for proper device operation. Copyright © 2009–2011, Texas Instruments Incorporated TLC59116F SCLS714B – MARCH 2009 – REVISED JULY 2011 www.ti.com AI[2:0] = 000 is used when the same register must be accessed several times during a single I2C bus communication, for example, changes the brightness of a single LED. Data is overwritten each time the register is accessed during a write operation. AI[2:0] = 100 is used when all the registers must be sequentially accessed, for example, power-up programming. AI[2:0] = 101 is used when the four LED drivers must be individually programmed with different values during the same I2C bus communication, for example, changing color setting to another color setting. AI[2:0] = 110 is used when the LED drivers must be globally programmed with different settings during the same I2C bus communication, for example, global brightness or blinking change. AI[2:0] = 111 is used when individually and global changes must be performed during the same I2C bus communication, for example, changing color and global brightness at the same time. Only the five least significant bits (LSBs) D[4:0] are affected by the AI[2:0] bits. When Control register is written, the register entry point determined by D[4:0] is the first register that will be addressed (read or write operation), and can be anywhere between 0 0000 and 1 1011 (as defined in ). When AI[2] = 1, the Auto-Increment flag is set and the rollover value at which the point where the register increment stops and goes to the next one is determined by AI[2:0]. See for rollover values. For example, if the Control register = 1111 0100 (F4h), then the register addressing sequence will be (in hex): 14 → … → 1B → 00 → … → 13 → 02 → … → 13 → 02 → … as long as the master keeps sending or reading data.

Default power-up values are D2h, D4h, D8h and the device(s) will not acknowledge these addresses right after power-up (the corresponding SUBx bit in MODE1 register is equal to 0). Once sub-addresses have been programmed to their right values, SUBx bits need to be set to 1 in order to have the device acknowledging these addresses (MODE1 register). Only the 7 MSBs representing the I2C bus sub-address are valid. The LSB in SUBADRx register is a read-only bit (0). When SUBx is set to 1, the corresponding I2C bus sub-address can be used during either an I2C bus read or write sequence. LED All-Call I2C Bus Address (ALLCALLADR) Register Table 10.

This address is programmable through the I2C bus and can be used during either an I2C bus read or write sequence. The register address can also be programmed as a Sub Call. Only the 7 MSBs representing the All Call I2C bus address are valid. The LSB in ALLCALLADR register is a read-only bit (0). If ALLCALL bit = 0 (MODE1), the device does not acknowledge the address programmed in register ALLCALLADR. Power-On Reset When power is applied to VCC, an internal power-on reset holds the TLC59116F in a reset condition until VCC reaches VPOR. At this point, the reset condition is released and the TLC59116F registers and I2C bus state machine are initialized to their default states causing all the channels to be deselected. Thereafter, VCC must be lowered below 0.2 V to reset the device. 16 Copyright © 2009–2011, Texas Instruments Incorporated TLC59116F www.ti.com SCLS714B – MARCH 2009 – REVISED JULY 2011 External Reset A reset can be accomplished by holding the RESET pin low for a minimum of tW. The TLC59116F registers and I2C state machine will be held in their default state until the RESET input is once again high. This input requires a pullup resistor to VCC if no active connection is used. Software Reset The software reset call (SWRST Call) allows all the devices in the I2C bus to be reset to the power-up state value through a specific formatted I2C bus command. To be performed correctly, it implies that the I2C bus is functional and that there is no device hanging the bus. The SWRST Call function is defined as the following: 1. A START command is sent by the I2C bus master. 2. The reserved SWRST I2C bus address '1101 011' with the R/W bit set to '0' (write) is sent by the I2C bus master. 3. The TLC59116F device(s) acknowledge(s) after seeing the SWRST Call address '1101 0110' (D6h) only. If the R/W bit is set to '1' (read), no acknowledge is returned to the I2C bus master. 4. Once the SWRST Call address has been sent and acknowledged, the master sends 2 bytes with 2 specific values (SWRST data byte 1 and byte 2): (a) Byte1 = A5h: the TLC59116F acknowledges this value only. If byte 1 is not equal to A5h, the TLC59116F does not acknowledge it. (b) Byte 2 = 5Ah: the TLC59116F acknowledges this value only. If byte 2 is not equal to 5Ah, the TLC59116F does not acknowledge it. If more than 2 bytes of data are sent, the TLC59116F does not acknowledge any more. 5. Once the right 2 bytes (SWRST data byte 1 and byte 2 only) have been sent and correctly acknowledged, the master sends a STOP command to end the SWRST Call: the TLC59116F then resets to the default value (power-up value) and is ready to be addressed again within the specified bus free time (tBUF). The I2C bus master must interpret a non-acknowledge from the TLC59116F (at any time) as a 'SWRST Call Abort'. The TLC59116F does not initiate a reset of its registers. This happens only when the format of the START Call sequence is not correct. Individual Brightness Control With Group Dimming/Blinking A 97-kHz fixed frequency signal with programmable duty cycle (8 bits, 256 steps) is used to control individually the brightness for each LED. On top of this signal, one of the following signals can be superimposed (this signal can be applied to the 4 LED outputs): • A lower 190 Hz fixed frequency signal with programmable duty cycle (8 bits, 256 steps) is used to provide a global brightness control. • A programmable frequency signal from 24 Hz to 1/10.73 s (8 bits, 256 steps) is used to provide a global blinking control.

Minimum pulse width for LEDn brightness control is 40 ns. B. Minimum pulse width for group dimming is 20.48 µs. C. When M = 1 (GRPPWM register value), the resulting LEDn brightness control and group dimming signal will have two pulses of the LED brightness control signal (pulse width = N × 40 ns, with N defined in the PWMx register). D. The resulting brightness plus group dimming signal shown above demonstrate a resulting control signal with M = 4 (8 pulses). Figure 9. Brightness and Group Dimming Signals Characteristics of the I2C Bus The I2C bus is for two-way, two-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pullup resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. Bit Transfer One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the high period of the clock pulse as changes in the data line at this time will be interpreted as control signals (see Figure 10). SDA SCL Data line stable; data valid Change of data allowed Figure 10. Bit Transfer 18 Copyright © 2009–2011, Texas Instruments Incorporated TLC59116F SCLS714B – MARCH 2009 – REVISED JULY 2011 www.ti.com START and STOP Conditions Both data and clock lines remain high when the bus is not busy. A high-to-low transition of the data line while the clock is high is defined as the START condition (S). A low-to-high transition of the data line while the clock is high is defined as the STOP condition (P) (see Figure 11). SDA SDA SCL SCL S P START Condition STOP Condition Figure 11. Definition of START and STOP Conditions System Configuration A device generating a message is a transmitter; a device receiving is the receiver. The device that controls the message is the master and the devices controlled by the master are the slaves (see Figure 12). SDA SCL MASTER TRANSMITTER/ RECEIVER SLAVE TRANSMITTER/ RECEIVER SLAVE RECEIVER MASTER TRANSMITTER MASTER TRANSMITTER/ RECEIVER 2 I C BUS MULTIPLEXER SLAVE Figure 12. System Configuration Acknowledge The number of data bytes transferred between the START and the STOP conditions from transmitter to receiver is not limited. Each byte of eight bits is followed by one acknowledge bit. The acknowledge bit is a high level put on the bus by the transmitter, whereas the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse, so that the SDA line is stable low during the high period of the acknowledge related clock pulse; set-up time and hold time must be taken into account. A master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line high to enable the master to generate a STOP condition.
