Cameras

LR38666Y

• Power supplies

DESCRIPTION

– +2.5 V for digital/analog circuits

– +3.3 V for digital circuits

The LR38666Y is a CMOS digital signal processor

for color digital still camera systems of 1 310 k/ 2 140 k/

3 300 k/3 370 k/4 200 k-pixel CCDs with primary

color mosaic filters.

• Package : 240-ball CSP (T-TFBGA240-1414)

FEATURES

• ARM7TDMI is used as the CPU core

• CCD signal processor modules

– Supported image size : 1 310 k/ 2 140 k/3 300 k/

3 370 k/4 200 k pixels

– R, G and B primary color mosaic filters :

Bayer matrix, 10 bits per color

– Built-in auto focus, auto exposure and auto

white balance functions

– Built-in digital clamp and gamma correction

functions

• Video encoder module

– Composite analog signal output mode :

Switchable between NTSC and PAL

– Built-in OSDC function

• JPEG encoding/decoding module :

Built-in circuits for encoding and decoding

– Encoding rate : Max. 66 ms per frame

(for 1/10-compression in VGA mode)

– Decoding rate : Max. 66 ms per frame

(for decompression in VGA mode)

(Assuming that SDRAM is used and the internal

bus is occupied by the JPEG module)

• SDRAM/flash memory controller module

• Synchronous/asynchronous SIO

• USB 1.0 is supported

• General purpose I/O ports

• Built-in audio I/F
