Features

1.1.1

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.

1.1.2

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.

1.1.3

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.

1.1.4

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)
