24AA08 datasheet


Description :

The Microchip Technology Inc. 24AA08/24LC08B (24XX08*) is a 8 Kbit Electrically Erasable PROM. The device is organized as four blocks of 256 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.7V, with standby and active currents of only 1 μA and 1 mA, respectively. The 24XX08 also has a page write capability for up to 16 bytes of data. The 24XX08 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2×3 DFN, 2×3 TDFN and MSOP packages, and is also available in the 5-lead SOT-23 package. All packages are Pb-free and RoHS compliant.


1. Single Supply with Operation down to 1.7V for 24AA08 and 24FC08 Devices, 2.5V for 24LC08B Devices

57F68 datasheet
Description :

Based on BlueCore 5-Multimedia, the BlueTunes ROM QFN integrates a Bluetooth radio, baseband, DSP, high-quality audio codec, SMPS, LDO and a battery charger for minimal BOM, component count and PCB area. BlueTunes ROM QFN uses advanced DSP features for the latest stereo enhancements and to improve audio quality, including SBC and MP3 decoder, support for FastStream (low-latency codec) and
5‑band EQ.

BlueTunes ROM QFN includes as standard cVc dual and single microphone algorithms for echo and noise suppression. cVc dual-microphone algorithm can provide >30dB of noise suppression in both stationary and dynamic noise conditions such as; babble, road, music and competing voices. In addition an acoustic echo canceller is now integrated into the cVc dualmicrophone solution, further enhancing the far-end
user experience.
