System LSI for Event data recorder
BU1511KV2
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.
ï½¥ARM946E-S
ï½¥Interrupt Controller
ï½¥External Memory Interface
ï½¥Timer/Timer Counter
ï½¥GPIO(16ch, PWM 4ch(shared), IRQ 4ch(shared)) ï½¥UART(2ch)
ï½¥SD Card Interface/SD Card Controller
ï½¥I2C Master Controller
ï½¥SSI(Synchronous Serial Interface)
ï½¥Camera Interface (up to 2M pixels)
ï½¥Watch Dog Timer
ï½¥JPEG Codec
ï½¥ADPCM Audio Codec with IIS Interface
･TV Encoder(within 75Ω driver)
ï½¥Clock Controller/PLL
ï½¥A/D Converter(4ch)
