ZHCSJB4D April 2019 – January 2024 TAS2563
PRODUCTION DATA
The TAS2563 has a global 7-bit I2C address 0x48. When enabled the device will additionally respond to I2C commands at this address once it is put in I2C Mode. This is used to speed up device configuration when using multiple TAS2563 devices and programming similar settings across all devices. The I2C ACK / NACK cannot be used during the multi-device writes since multiple devices are responding to the I2C command. The I2C CRC function should be used to ensure each device properly received the I2C commands. At the completion of writing multiple devices using the global address, the CRC at I2C_CKSUM register should be checked on each device using the local address for a proper value. The global I2C address can be disabled using I2C_GBL_EN register. The I2C address is detected by sampling the address pins when SDZ pin is released. Additionally, the address may be re-detected by setting I2C_AD_DET high after power up and the pins will be resampled.
