Features
DSP56300 Modular Chassis
• 120 Million Instructions Per Second (MIPS) with an 120 MHz clock at 3.3V.
• Object Code Compatible with the 56K core.
• Data ALU with a 24 x 24 bit multiplier-accumulator and a 56-bit barrel shifter. 16-bit arithmetic
support.
• Program Control with position independent code support and instruction cache support.
• Six-channel DMA controller.
• PLL based clocking with a wide range of frequency multiplications (1 to 4096), predivider factors
(1 to 16) and power saving clock divider (2i: i=0 to 7). Reduces clock noise.
• Internal address tracing support and OnCE™ for Hardware/Software debugging.
• JTAG port.
• Very low-power CMOS design, fully static design with operating frequencies down to DC.
• STOP and WAIT low-power standby modes.
On-chip Memory Configuration
• 7Kx24 Bit Y-Data RAM and 8Kx24 Bit Y-Data ROM.
• 13Kx24 Bit X-Data RAM and 32Kx24 Bit X-Data ROM.
• 40Kx24 Bit Program ROM.
• 3Kx24 Bit Program RAM and 192x24 Bit Bootstrap ROM. 1K of Program RAM may be used as
Instruction Cache or for Program ROM patching.
• 2Kx24 Bit from Y Data RAM and 5Kx24 Bit from X Data RAM can be switched to Program RAM
resulting in up to 10Kx24 Bit of Program RAM.
Off-chip Memory Expansion
• External Memory Expansion Port.
• Off-chip expansion up to two 16M x 24-bit word of Data memory.
• Off-chip expansion up to 16M x 24-bit word of Program memory.
• Simultaneous glueless interface to SRAM and DRAM.
Peripheral Modules
• Serial Audio Interface (ESAI): up to 4 receivers and up to 6 transmitters, master or slave. I2S, Sony,
AC97, network and other programmable protocols.
• Serial Audio Interface I(ESAI_1): up to 4 receivers and up to 6 transmitters, master or slave. I2S,
Sony, AC97, network and other programmable protocols
The ESAI_1 shares four of the data pins with ESAI, and ESAI_1 does NOT support HCKR and
HCKT (high frequency clocks)
• Serial Host Interface (SHI): SPI and I2C protocols, multi master capability, 10-word receive FIFO,
support for 8, 16 and 24-bit words.
• Byte-wide parallel Host Interface (HDI08) with DMA support.
• Triple Timer module (TEC).
• Digital Audio Transmitter (DAX): 1 serial transmitter capable of supporting the SPDIF, IEC958,
CP-340 and AES/EBU digital audio formats.
• Pins of unused peripherals (except SHI) may be programmed as GPIO lines.
