1.1

Features

1.1.1

Digital Signal Processing Core

•

100 Million Instructions Per Second (MIPS) with an 100 MHz clock at 3.3V.

•

Object Code Compatible with the 56000 core.

•

Data ALU with a 24

× 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

•

1.5K

× 24 Bit Y-Data RAM.

•1K

× 24 Bit X-Data RAM.

•8K

× 24 Bit Program ROM.

•

0.5K

× 24 Bit Program RAM and 192 × 24 Bit Bootstrap ROM.

•

0.75K

× 24 Bit from Y Data RAM can be switched to Program RAM resulting in up to 1.25K × 24

Bit of Program RAM.

1.1.3

Off-Chip Memory Expansion

•

External Memory Expansion Port with 8-bit data bus.

•

Off-chip expansion up to 2

× 16M × 8-bit word of Data/Program memory when using DRAM.

•

Off-chip expansion up to 2

× 256k × 8-bit word of Data/Program memory when using SRAM.

•

Simultaneous glueless interface to SRAM and DRAM.

1.1.4

Peripheral Modules

•

Enhanced Serial Audio Interface (ESAI): 6 serial lines, 4 selectable as receive or transmit and 2

transmit only, master or slave. I2S, Sony, AC97, network and other programmable protocols.

Unused pins of ESAI may be used as GPIO lines.

•

Serial Host Interface (SHI): SPI and I2C protocols, 10-word receive FIFO, support for 8, 16 and

24-bit words.

•

Four dedicated GPIO lines.
