CAT9532 16-bit Programmable LED Dimmer with I2C Interface FEATURES 16 LED drivers with dimming control 256 brightness steps 16 open drain outputs drive 25 mA each 2 selectable programmable blink rates: – frequency: 0.593Hz to 152Hz – duty cycle: 0% to 99.6% I/Os can be used as GPIOs 400kHz I2C bus compatible* 2.3V to 5.5V operation 5V tolerant I/Os Active low reset input RoHS-compliant 24-Lead SOIC, TSSOP and 24-pad TQFN (4 x 4mm) packages DESCRIPTION The CAT9532 is a CMOS device that provides 16-bit parallel input/output port expander optimized for LED dimming control. The CAT9532 outputs can drive directly 16 LEDs in parallel. Each individual LED may be turned ON, OFF, or blinking at one of two programmable rates. The device provides a simple solution for dimming LEDs in 256 brightness steps for backlight and color mixing applications. The CAT9532 is suitable in I2C and SMBus compatible applications where it is necessary to limit the bus traffic or free-up the bus master’s timer. The CAT9532 contains an internal oscillator and two PWM signals that drive the LED outputs. The user can program the period and duty cycle for each individual PWM signal. After the initial set-up command to program the Blink Rate 1 and Blink Rate 2 (frequency and duty cycle), only one command from the bus master is required to turn each individual open drain output ON, OFF, or cycle at Blink Rate 1 or Blink Rate 2. Each open drain LED output can provide a maximum output current of 25mA. The total current sunk by all I/Os must not exceed 200mA.

The SCL line requires a pull-up resistor if it is driven by an open drain output. SDA: Serial Data/Address The bidirectional serial data/address pin is used to transfer all data into and out of the device. The SDA pin is an open drain output and can be wire-ORed with other open drain or open collector outputs. A pullup resistor must be connected from SDA line to VCC. LED0 to LED15: LED Driver Outputs / General Purpose I/Os The pins are open drain outputs used to drive directly LEDs. Any of these pins can be programmed to drive the LED ON, OFF, Blink Rate1 or Blink Rate2. When not used for controlling the LEDs, these pins may be used as general purpose parallel input/output. ¯¯¯¯¯¯ RESET: External Reset Input Active low Reset input is used to initialize the 2 CAT9532 internal registers and the I C state machine. The internal registers are held in their default state while Reset input is active. An external pull-up resistor of maximum 25kΩ is required when this pin is not actively driven. Doc.

The CAT9532 supports the I C Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol defines any device that sends data to the bus to be a transmitter and any device receiving data to be a receiver. The transfer is controlled by the Master device which generates the serial clock and all START and STOP conditions for bus access. The CAT9532 operates as a Slave device. Both the Master device and Slave device can operate as either transmitter or receiver, but the Master device controls which mode is activated. I C Bus Protocol The features of the I2C bus protocol are defined as follows: (1) Data transfer may be initiated only when the bus is not busy. (2) During a data transfer, the data line must remain stable whenever the clock line is high. Any changes in the data line while the clock line is high will be interpreted as a START or STOP condition (Figure 2). START and STOP Conditions The START Condition precedes all commands to the device, and is defined as a HIGH to LOW transition of 2 2 SDA when SCL is HIGH. The CAT9532 monitors the SDA and SCL lines and will not respond until this condition is met. A LOW to HIGH transition of SDA when SCL is HIGH determines the STOP condition. All operations must end with a STOP condition. Device Addressing After the bus Master sends a START condition, a slave address byte is required to enable the CAT9532 for a read or write operation. The four most significant bits of the slave address are fixed as binary 1100 (Figure 3). The CAT9532 uses the next three bits as address bits. The address bits A2, A1 and A0 are used to select which device is accessed from maximum eight devices on the same bus. These bits must compare to their hardwired input pins. The 8th bit following the 7bit slave address is the R/W bit that specifies whether a read or write operation is to be performed. When this bit is set to “1”, a read operation is initiated, and when set to “0”, a write operation is selected. Following the START condition and the slave address byte, the CAT9532 monitors the bus and responds with an acknowledge (on the SDA line) when its address matches the transmitted slave address. The CAT9532 then performs a read or a write operation depending on the state of the R/W bit. Figure 2. Start/Stop Timing SDA SCL START CONDITION STOP CONDITION Figure 3.

No. MD-9001 Rev. E CAT9532 Acknowledge After a successful data transfer, each receiving device is required to generate an acknowledge. The acknowledging device pulls down the SDA line during the ninth clock cycle, signaling that it received the 8 bits of data. The SDA line remains stable LOW during the HIGH period of the acknowledge related clock pulse (Figure 4). The CAT9532 responds with an acknowledge after receiving a START condition and its slave address. If the device has been selected along with a write operation, it responds with an acknowledge after receiving each 8- bit byte. W hen the CAT9532 begins a READ mode it transmits 8 bits of data, releases the SDA line, and monitors the line for an acknowledge. Once it receives this acknowledge, the CAT9532 will continue to transmit data. If no acknowledge is sent by the Master, the device terminates data transmission and waits for a STOP condition. The master must then issue a stop condition to return the CAT9532 to the standby power mode and place the device in a known state. Registers and Bus Transactions After the successful acknowledgement of the slave address, the bus master will send a command byte to the CAT9532 which will be stored in the Control Register. The format of the Control Register is shown in Figure 5. The Control Register acts as a pointer to determine which register will be written or read. The four least significant bits, B0, B1, B2, B3, are used to select which internal register is accessed, according to the Table 1. If the auto increment flag (AI) is set, the four least significant bits of the Control Register are automatically incremented after a read or write operation. This allows the user to access the CAT9532 internal registers sequentially. The content of these bits will rollover to “0000” after the last register is accessed. T able 1.

E CAT9532 Write Operations Data is transmitted to the CAT9532 registers using the write sequence shown in Figure 6. If the AI bit from the command byte is set to “1”, the CAT9532 internal registers can be written sequentially. After sending data to one register, the next data byte will be sent to the next register sequentially addressed. Read Operations The CAT9532 registers are read according to the timing diagrams shown in Figure 7 and Figure 8. Data from the register, defined by the command byte, will be sent serially on the SDA line. After the first byte is read, additional data bytes may be read when the auto-increment flag, AI, is set. The additional data byte will reflect the data read from the next register sequentially addressed by the (B3 B2 B1 B0) bits of the command byte. W hen reading Input Port Registers (Figure 8), data is clocked into the register on the failing edge of the acknowledge clock pulse. The transfer is stopped when the master will not acknowledge the data byte received and issue the STOP condition. Figure 6.

W hen used as input, the user should program the corresponding LED pin to Hi-Z (“00” for the LSx register bits). The pin state can be read via the Input Register according to the sequence shown in Figure 8. For use as output, an external pull-up resistor should be connected to the pin. The value of the pull-up resistor is calculated according to the DC operating characteristics. To set the LED output high, the user has to program the output Hi-Z writing “00” into the corresponding LED Selector (LSx) register bits. The output pin is set low when the LED output is programmed low through the LSx register bits (“01” in LSx register bits).

The external Reset timing is shown in Figure 9. Power-On Reset Operation The CAT9532 incorporates Power-On Reset (POR) circuitry which protects the internal logic against powering up in the wrong state. The device is in a reset state for VCC less than the internal POR threshold level (VPOR). When VCC exceeds the VPOR level, the reset state is released and the CAT9532 internal state machine and registers are initialized to their default state. Figure 8.
