Product Overview CSR's popular BlueCore5-Multimedia platform is software-portable to the BlueCore CSR8670 BGA, with easy migration of a broad range of solutions from CSR's eXtension partners. This migration enables rapid time-tomarket deployment of a broad range of consumer electronics products. The enhanced Kalimba DSP coprocessor with 80MIPS supports enhanced audio and DSP applications. 2.1. Hardware Overview 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; 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 CSR's latest CVC technology for narrow-band and wideband voice connections including wind noise reduction Audio interfaces: IS, PCM and SPDIF Serial interfaces: UART, USB 2.0 full-speed, master and slave bit-serialiser (IC 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 capacitive touch sensor inputs 6.5 x 6.5 x 1mm, 0.5mm pitch 112ball VFBGA Green (RoHS compliant and no antimony or halogenated flame retardants) 2.2. Product Type Declaration This product is listed as Bluetooth Component Product. If you use this product to implement Bluetooth in your product's design further qualification and listing is required in accordance with the Bluetooth Qualification Process (ref. PRD 2.0). To start the process for a new qualification, visit https://www.bluetooth.org/TPG/. 2.3. Standard Operating Conditions The standard operating conditions for the CSR8670 BGA are: Operating Temperature: -30 to +85 Storage Temperature: -40 to +50 Voltage Supply: 3.7 V DC (c) Cambridge Silicon Radio Limited 2011 This material is subject to CSR's non-disclosure agreement Page 5 of 11 CS-216833-DCP1 www.csr.com CSR8670 Reference Integration Note Document (Miscellaneous) The BlueCore(R) CSR8670TM BGA 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.
