System LSI for Event data recorder
BU1511KV2
Function
BU1511KV2 is a system LSI for event data recorder that makes developing it easier
BU1511KV2 have built-in specific hardware to communicate and control with a 3-axis
accelerometer and a camera module, SD card, etc. that are recommended for event data
recorder.
The specific hardware are controllerable by built-in ARM946E-S, which can execute various
applications.
The following function blocks are built-in.
・ARM946E-S
・External Memory Interface
・Interrupt Controller
・Timer/Timer Counter
・GPIO(16ch, PWM 4ch(shared), IRQ 4ch(shared)) ・UART(2ch)
・SD Card Interface/SD Card Controller
・SSI(Synchronous Serial Interface)
・Watch Dog Timer
・I2C Master Controller
・Camera Interface (up to 2M pixels)
・JPEG Codec
・ADPCM Audio Codec with IIS Interface
・TV Encoder(within 75Ω driver)
・Clock Controller/PLL
・A/D Converter(4ch)
