Overview
INTEGRATED CIRCUITS DATA SHEET SAA8122 Digital Still Camera Preliminary specification Supersedes data of File under Integrated Circuits, ICXX 1999 sep 01 Philips Semiconductors Preliminary specification Digital Still Camera FEATURES • Support a wide range of CCD (VGA,SVGA,QGA,XGA,EQGA) • Perform an advanced RGB to YUV conversion • Support smart measurement unit to speed up the control loop (Focus, auto white balance,.
.
.
) • Support a wide range of LCD and TV format (NTSC and PAL) with text re-insertion features • Support an embedded JPEG encoder/decoder unit.
• MIPS PR3001 CPU, running in a frequency range from 12 to 28 MHz.
SAA8122 • PRISC compatible PI-bus architecture, interrupt, power management, clock and reset architectures.
• Support a dedicated video bus and SDRAM memory for picture storage • Support for ROM, DRAM,SRAM, flash and PC Card (Compact Flash and SSFDC).
• Integrated general purpose peripherals like a USB,FIR,UART, timers, an I2C transceiver, ADC converters, RTC and IO ports.
EXTERNAL UNTERFACES • a dedicated interface to IEEE 1394 devices (such as Philips’ PDI 1394 chip-set) • two UART (RS-232) data ports with DMA capabilities (≤ 187.
5kbit/s) including hardware flow control RxD, TxD, RTS, CTS for modem support • 32 general purpose, bidirectional I/O interface pins, the first 8 bits may also be used as interrupt inputs • two PWM output (8 bit resolution) CPU relqted features • a 32-bit PR3001 core • 1 KB (kilo byte) data cache and 4 KB instruction cache • a programmable low-power mode, including wake-up on interrupt • a memory management unit (TLB: translation lookaside buffer) • two built in 24-bit general purpose timers and one 24-bit watchdog timer in coprocessor zero two built in 24-bit general purpose timers • a real-time clock unit (active in sleep mode) • an on-chip 8 KBytes SRAM for storing code which needs fast execution GENERAL DESCRIPTION The DSC SAA8122E/C1 is a high performance, low power, single-chip MIPS based microprocessor whi...
