Introduction FM1288 is the new generation of Fortemedia's system-on-chip (SoC)solution that provides high performance voice processing for automotive hands-free applications. It delivers state of the art single microphone and dual-microphone noise suppression with acoustic echo cancellation technologies for in vehicle and personal navigation devices(pnd)based hands-free voice communications 11 Overview Incorporating the latest Fortemedia technologies for removing ambient noise and acoustic echoes, the FM1288 preserves voice naturalness for greater speech intelligibility in a variety of noisy automotive enviroments. Designed to be compatible with a wide range of host processors and blue-tooth devices the FM1288 voice processor is designed for easy system integration The FM1288 provides system designer the flexibilities to customize each processing module and fine-tune the algorithms to the unique needs and acoustic path characteristics of the manufacturer's automotive model cabin or handsfree communication device 1.2 Key Features Highly integrated soc o Digital Signal Processor(dSP)with Hardware Accelerators RAM, and rom o 3 ADC (Analog to Digital Converter) o 2 DAC(Digital to Analog Converter) o Differential i o on all analogs to improve noise immunit 2 On-chip analog microphone inputs IIC-Compatible Serial (SHi) and UART control interface to host processor o IIS-Compatible and pCm data interface to host or bluetooth processor o Built-in PLL supports highly flexible clocking input o Can operate as Co-processor or as standalone processor High performance o Advanced algorithms for acoustic echo cancellation and noise reduction Robust full-duplex for in-vehicle applications o Preserves voice naturalness and effective in automotive environment o Wideband(hd voice and narrowband voice processing o Bright Voice Enhancement(BVE) for downlink listening improvement o Dynamic Range Control(DRC) for range control o Equalization(EQL) on uplink and downlink voice paths o Line in and Line out signal path automatic Gain Control (AGC) o Configurable processing modules performance o Non-invasive run-time performance tuning via UART and IIc-compatible port Run time switching between processing mode and various by-pass modes o User-selectable between two microphone inputs usage-one for front-seat passengers and another for back-seat passengers in vehicle cabins Available in 48-pin LQFP packages, Automotive Grade 8P a g 1.3 Pin Configuration (LQFP) 出9a口 z¥三 十 VDD C SDA VSS A MICO P VAD LED MIC0N囗 MUTE OUT MIC1 P MUTE IN MIC1 N VDD D LINE IN P OO LINE IN_N囗 GPIO VSS A O SCL EE VREF SDA EE LINE OUT P口 TEST2 Pin 1 SPK OUT_P囗 UART TX 廿凵 乙呈兰兰9总影 u Figure 1: LQFP 48-Pin Configuration-Top View 9P a g 1. 4 Device Terminal Functions Analog Audio I/O Lead Pad type Supply Description Domain LINE OUT N Analogue VDD A AudIo LINE OUTPUT () LINE OUT P Analogue VDD A Audio LINE OUTPUT (+ sPK。UTN Analogue VDD Audio SPEAKER OUTPUT(-) SPK QUT P 48 Analogue VDD A Audio SPEAKER OUTPUT (+) LINE IN N Analogue VDD A Audio LINE INPUT(-) LINE IN P 43 Analogue VDD A Audio LINE INPUT(+) MICO 40 Analogue VDD A Audio MIC INPUT(-) MICO P 39 Analogue VDD A Audio MIC INPUT (+) M工c1N 42 Analogue VDD A Audio MIC INPUT(-) MICI P 41 Analoque VDD Audio Mic INPut(+) oscilator and clock Lead Pad Type Supply Description Domain XTAL_ IN/MCLK_IN 27 Ial VDD D For crystal or external clock in XTAL OUT/MCLK_OUT 28 Digital VDD D Drive for crystal 0P a g
