1 / 2 page  Features CSR8670™ BGA ■ Bluetooth® v3.0 specification fully qualified software ■ Bluetooth v4.0 specification compliant hardware ■ Radio includes integrated balun and RF performance of 10dBm transmit power and -90dBm receive sensitivity ■ 80MHz RISC MCU and 80MIPS Kalimba DSP ■ 16Mb internal flash memory (64-bit wide, 45ns); optional support for 64Mb of external SPI flash ■ Stereo codec with 2 channels of ADC and up to 6 microphone inputs (includes bias generators and digital microphone support) ■ Support for latest CVC technology for narrow- band and wideband voice connections including wind noise reduction ■ Audio interfaces: I²S, PCM and SPDIF ■ Serial interfaces: UART, USB 2.0 full-speed, master and slave bit-serialiser (I²C and SPI) ■ Integrated dual switch-mode regulators, linear regulators and battery charger ■ 3 hardware LED controllers (for RGB) and ability to drive LCD segment display directly ■ Support for up to 6 capacitive touch sensor inputs ■ 6.5 x 6.5 x 1mm, 0.5mm pitch 112‑ball VFBGA ■ Green (RoHS compliant and no antimony or halogenated flame retardants) Low-power Solution for DSP Intensive Audio Applications Production Information CSR8670 Issue 2 2.4GHz Radio + Balun I/O BT_RF RAM Baseband MCU Kalimba DSP Flash XTAL Serial Flash External Memory UART/USB PIO Audio In /Out PCM/I2S/ SPDIF SPI/I2C LED /PO Audio Interface Capacitive Sense Clock Generation General Description CSR8670 consumer audio platform for wired and wireless applications integrates an ultra-low-power DSP and application processor with embedded flash memory, a high-performance stereo codec, a power management subsystem, LED and LCD drivers and capacitive touch sensor inputs in a SOC IC. The dual-core architecture with flash memory enables manufacturers to easily differentiate their products with new features without extending development cycles. BlueCore5-Multimedia® platform is software-portable to the CSR8670, with easy migration of a broad range of solutions from eXtension partners. This migration enables rapid time-to-market deployment of a broad range of consumer electronics products. The enhanced Kalimba DSP coprocessor with 80MIPS supports enhanced audio and DSP applications. Applications Home Entertainment Ecosystem ■ TVs ■ Smart remote controllers ■ Wired or wireless soundbars ■ Wired or wireless speakers and headphones Tablets / PCs / Mobile Connectivity ■ Wearable audio (on-the-go) ■ Wearable audio with sensors (health and well- being applications) ■ Wired or wireless stereo headphones for music/ gaming/multimedia content ■ Wired or wireless speakers ■ Wired or wireless speakerphones ■ Mono headsets for voice The audio codec supports 2 ADC channels, up to 6 microphone inputs, stereo output and a variety of audio standards.
