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 25 mA. The total current sunk by all I/Os must not exceed 200 mA.

The CAV24C02 is a EEPROM Serial 2-Kb I2C - Automotive Grade device organized internally as 16 pages of 16 bytes each. This device supports both the Standard (100 kHz) as well as Fast (400 kHz) I2C protocol.Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a Page Write Buffer, and then writing all data to non-volatile memory in one internal write cycle. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count.External address pins make it possible to address up to eight CAV24C02 devices on the same bus.

The CAV24C04 is a EEPROM Serial 4-Kb I2C - Automotive Grade device organized internally as 32 pages of 16 bytes each. This device supports both the Standard (100 kHz) as well as Fast (400 kHz) I2C protocol.Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a Page Write Buffer, and then writing all data to non-volatile memory in one internal write cycle. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count.External address pins make it possible to address up to four CAV24C04 devices on the same bus.

The CAV24C256 is a EEPROM Serial 256-Kb I2C - Automotive Grade, internally organized as 32,768 words of 8 bits each.It features a 64-byte page write buffer and supports the Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I2C protocol.Write operations can be inhibited by taking the WP pin High (this protects the entire memory).External address pins make it possible to address up to eight CAV24C256 devices on the same bus.On-Chip ECC (Error Correction Code) makes the device suitable for high reliability applications.
