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.
