1.2 56858 Description
The 56858 is a member of the 56800E core-based family of controllers. This device combines the processing power of a Digital Signal Processor (DSP) and the functionality of a microcontroller with a flexible set of peripherals on a single chip to create an extremely cost-effective solution. The low cost, flexibility, and compact program code make this device well-suited for many applications. The 56858 includes peripherals that are especially useful for teledatacom devices; Internet appliances; portable devices; TAD; voice recognition; hands-free devices; and general purpose applications. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C Compilers, enabling rapid development of optimized control applications. The 56858 supports program execution from either internal or external memories. Two data operands can be accessed from the on-chip Data RAM per instruction cycle. The 56858 also provides two external dedicated interrupt lines, and up to 47 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56858 controller includes 40K words of Program RAM, 24K words of Data RAM and 1K of Boot RAM. It also supports program execution from external memory. This controller also provides a full set of standard programmable peripherals that include an 8-bit Parallel Host Interface, two Enhanced Synchronous Serial Interfaces (ESSI), one Serial Peripheral Interface (SPI), two Serial Communications Interfaces (SCI), and one Quad Timer. The Host Interface, Quad Timer, SSI, SPI, SCI I/O and four chip selects can be used as General Purpose Input/Outputs when its primary function is not required.
1.3 State of the Art Development Environment
• • Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use component-based software application creation with an expert knowledge system. The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation, compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards will support concurrent engineering. Together, PE, Code Warrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development.

1.5 Data Sheet Conventions
This data sheet uses the following conventions:
OVERBAR “asserted” “deasserted” Examples:
This is used to indicate a signal that is active when pulled low. For example, the RESET pin is active when low. A high true (active high) signal is high or a low true (active low) signal is low. A high true (active high) signal is low or a low true (active low) signal is high. Signal/Symbol PIN PIN PIN PIN Logic State True False True False Signal State Asserted Deasserted Asserted Deasserted Voltage1 VIL/VOL VIH/VOH VIH/VOH VIL/VOL
1. Values for VIL, VOL, VIH, and VOH are defined by individual product specifications.
