Pin description
SPEAr300
The following modes can be selected by programming some control registers present in the
reconfigurable array subsystem.
● NAND mode
● NOR Mode
● PHOTO_FRAME Mode (PHOTO FRAME)
● LEND_IP_PHONE Mode (LOW END IP PHONE)
● HEND_IP_PHONEMode (HIGH END IP PHONE)
● LEND_WIFI_PHONE Mode (LOW END WI-FI PHONE)
● HEND_WIFI_PHONE Mode (HIGH END WI-FI PHONE)
● ATA_PABX_wI2S Mode (ATA PABX without I2S)
● ATA_PABX_I2S Mode (ATA PABX with I2S)
● CAMl_LCDw Mode (8-bit CAMERA without LCD)
● CAMu_LCD Mode (14-bit camera with LCD)
● CAMu_wLCD Mode (14-bit camera without LCD)
● CAMl_LCD Mode (8-bit camera with LCD)
Configuration 1 is the default mode for SPEAr300. It supports the FSMC interface for NAND
Flash connectivity and boot pins used for selecting the boot mode.
Mode 1: NAND interface
NAND mode mainly provides:
● NAND Flash interface (16 bits, 5 control signals)
Mode 2: NOR interface
NOR mode mainly provides:
● External Memory Interface (16 data bits, 24 address bits and 4 chip selects)
Mode 3: Photo frame
Photo frame mode mainly provides:
● NAND Flash interface (16 bits, 5 control signals)
● CLCD controller interface
● TDM for voice/music capabilities
● SDIO interface supporting SPI, SD1, SD4 and SD8 mode
● GPIOs with interrupt capability
Mode 4: Low end IP phone
Low end IP phone mode mainly provides:
● 9x9 keyboard
● 8 SPI/I2C control signals
● I2S block
● GPIOs with interrupt capability
● Digital-to-analog converter (DAC)
