Product Name

System LSI for Event data recorder

Type

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

･Interrupt Controller

･External Memory Interface

･Timer/Timer Counter

･GPIO(16ch, PWM 4ch(shared), IRQ 4ch(shared))

･UART(2ch)

･SD Card Interface/SD Card Controller

･I2C Master Controller

･SSI(Synchronous Serial Interface)

･Camera Interface (up to 2M pixels)

･Watch Dog Timer

･JPEG Codec

･ADPCM Audio Codec with IIS Interface

･Clock Controller/PLL

･TV Encoder(within 75

Ω driver)

･A/D Converter(4ch)
