Freescale Semiconductor, Inc.  
HYBRID MCU/DSP  
56855  
120 MIPS Hybrid Processor  
TARGET APPLICATIONS  
BENEFITS  
• Internet audio decoding  
• DTAD  
• Voice recognition and command  
• Embedded modem/data pump  
• Voice processing  
• Easy to program with flexible  
application development tools  
• Time of Day for applications requiring  
clock display  
• Supports multiple processor  
connections  
• Flexible 6-Channel Direct Memory  
Access (DMA) allows both internal and  
external memory transfers with almost  
no CPU interruption  
• General purpose devices  
• Automotive hands-free  
• 16-bit quad timer module (with one  
external pin) that allows  
capture/compare functionality,  
and can be cascaded  
• External memory expansion up to 2M  
words program memory or up to 8M  
words data memory increases  
capabilities of device for larger  
algorithms  
• Quad timer module can also be used for  
simple digital-to-analog conversion  
functionality  
• Enhanced synchronous serial interface  
with enhanced network and audio modes  
The 56855 offers 48 KB of on-chip program SRAM  
and 48 KB data SRAM in a 100-pin LQFP package.  
The serial peripheral interface (SPI) and the 8-bit  
host interface have been removed to provide  
flexibility with fewer features to meet customer  
price/performance expectations. This device is ideal  
for systems that require a DSP with greater on-chip  
memory in a smaller package, but do not require an  
extensive peripheral set. The 56855 includes a quad  
timer module with a signal external output.  
56855 16-BIT DIGITAL SIGNAL PROCESSORS  
• 120 MIPS at 120MHz  
• 48 KB Program SRAM  
• 48 KB Data SRAM  
• 2 KB Boot ROM  
• Two Serial Communication Interfaces  
(SCI)  
• General purpose 16-bit Quad Timer  
• JTAG/Enhanced On-Chip Emulation  
(OnCE) for unobtrusive, real-time  
debugging  
• Access up to 4 MB of program memory  
or up to 16 MB of data memory  
• Computer Operating Properly  
(COP)/Watchdog Timer  
• Chip Select Logic for glueless interface  
to ROM and SRAM  
• Time of Day (TOD)  
• 100-pin LQFP package  
• Up to 18 GPIO  
• Six independent channels of DMA  
• Enhanced Synchronous Serial Interface  
(ESSI)
