Airoha Technology has selected STMicroelectronics’ “dynamic NFC tag” memories for its Bluetooth audio modules.
ST’s M24SR is the key component for Bluetooth pairing and parameter storage on Airoha’s AB1510/AB1511 optimized single-chip solution with integrated baseband and radio for stereo and mono-A2DP1 headset and speaker applications. Instead of the cumbersome device connection setup, users can now simply start streaming dynamic sounds from NFC-enabled smartphones or tablets with a single tap.
“With the increasing demand for NFC in Bluetooth speaker designs, ST’s “dynamic NFC tag” memories make it extremely easy for users to pair an NFC-enabled smartphone or tablet with portable speakers to instantly stream high-quality music via Bluetooth,” said Arnaud Julienne, Senior Director of MMS, Greater China and South Asia Region, STMicroelectronics. “The cooperation with Airoha has produced the world’s first Bluetooth module that takes advantages of our new dynamic NFC tags.”
“The 64K EEPROM in ST’s M24SR eliminates the need for external EEPROM, reduces the overall module size as well as the development time. The MCU embedded in the new AB1510/AB1511 works well with ST’s dynamic NFC tags directly, resulting in fast and easy production, “ said Dr. David Chang, President and CEO of Airoha Technology. “Our new audio solutions based on ST’s dynamic NFC tag memories have already been adopted by many Tier-1 headset and speaker manufacturers.”
Features of the M24SR family include:
NFC Forum Tag Type 4 based on ISO 14443 RF interface
1 MHz I²C serial interface operating from 2.7 to 5.5V
EEPROM memory density from 2 Kbits to 64 Kbits with built-in NDEF message support
RF disable pin allowing the application to control RF access from NFC phones
128-bit password protection
General-purpose output pin allowing flexibility for the applications (wake up on several types of events)
Simple antenna design, backward compatible with M24LR series
