Seiko Epson Corp. has developed the S2S65A00 image controller IC, which enables simultaneously recording and transmitting images from two cameras. Based on S1S65010 network camera controller IC, S2S65A00 is designed for use as an image controller for products such as drive recorders and vehicle-mounted cameras. It features two camera interface functions and two JPEG encoder functions. It also comes equipped with CF/SD memory, USB 2.0 (supporting high speeds) and an 8-ch A/C converter.

S2S65A00 provides a one-chip solution that can be used to lower system costs, said the company. The chip is equipped with ARM720T Rev4.3 (with 8 Kbyte cache) and features a 30fps VGA hardware that makes JPEG encoding possible (compliant with ISO 10918). The image controller IC can be connected to two camera modules. It has two hardware JPEG encoders that can be installed for each camera module.

The chip also has a motion detection function to support motion detection for 16 (4 x 4) areas. It also features an audio data supported by I2S.

S2S65A00 is also compatible with CF memory card and wireless LAN interface (802.11b/g) through CompactFlash interface. Its SD memory supports connection to SC memory cards.

With its USB 2.0 - HS (device) function support, the chip can connect to PCs (EP8, 4Kbyte FIFO RAM). It also has an 8-ch ADC support that allows for connection to various types of analog sensors.

Additionally, the image controller IC is equipped with a timer for event counter and supports serial interfaces such as I2S, I2C, UART and SPI. It features two ports for memory bus, 16bit bus for FROM/SRAM and 32bit bus for SDRAM.

Packaged in PFBGA-280 (ball pitch 0.8mm), the chip has a power supply voltage of 1.8 V(core), 3.3V (I/O) and 2.4-3.6V (camera I/O).

Epson also announced that it has developed S2S65P10 I/P converter IC for multivideo input. This product uses the S2S65A00 in a chip set, making it possible to connect a maximum of eight camera sets (camera modules and NTSC/PAL decoders).
