4 Loop Airbag Deployment ASSP

CrosSave^TM

T h e T L e 7 7 1 4 / 3 4 is intꢀndꢀd to bꢀ usꢀd in an Automotivꢀ Rꢀstrain

control modulꢀ. Tꢁꢀ dꢀvicꢀ allows individual control of up to four squib dꢀvicꢀs

in CrosSavꢀ^TMstandard conﬁguration. It providꢀs also a communication solution

witꢁ a Mastꢀr µC dꢀvicꢀ (MCU) via a 16-Bit full duplꢀx 8 Mhz SPI intꢀrfacꢀ. Tꢁꢀ IC

is ꢀquippꢀd witꢁ tꢁꢀ rꢀquirꢀd ꢁardwarꢀ to avoid or ꢀnablꢀ dꢀploymꢀnt as wꢀll as
