Freescale Semiconductor

Preliminary

from the on-chip data RAM per instruction cycle. The 56F8037 also offers up to 53 General Purpose

Input/Output (GPIO) lines, depending on peripheral configuration.

The 56F8037 Digital Signal Controller includes 64KB of Program Flash and 8KB of Unified

Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages.

Program Flash page erase size is 512 Bytes (256 Words).

A full set of programmable peripherals—PWM, ADCs, QSCIs, QSPIs, I2C, PITs, Quad Timers, DACs

and analog comparators—supports various applications. Each peripheral can be independently shut down

to save power. Any pin in these peripherals can also be used as General Purpose Input/Outputs (GPIOs).

1.3 Award-Winning 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 CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,

compiling, and debugging. A complete set of evaluation modules (EVMs), demonstration board kit and

development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs

create a complete, scalable tools solution for easy, fast, and efficient development.

1.4 Architecture Block Diagram

The 56F8037’s architecture is shown in Figures 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, and 1-7. Figure 1-1 illustrates

how the 56800E system buses communicate with internal memories and the IPBus Bridge and the internal

connections between each unit of the 56800E core. Figure 1-2 shows the peripherals and control blocks

connected to the IPBus Bridge. Figures 1-3, 1-4, 1-5, 1-6 and 1-7 detail how the device’s I/O pins are

muxed. The figures do not show the on-board regulator and power and ground signals. Please see Part 2,

Signal/Connection Descriptions, for information about which signals are multiplexed with those of other

peripherals.

1.4.1

PWM, TMR and ADC Connections

Figure 1-3 shows the over- and under-voltage connections from the ADC to the PWM and the connections

to the PWM from the TMR and GPIO. These signals can control the PWM outputs in a similar manner to

the over- and under-voltage control signals. See the 56F802x and 56F803x Peripheral Reference

Manual for additional information.

The PWM_reload_sync output can be connected to Timer A’s (TMRA) Channel 3 input; TMRA’s

Channels 2 and 3 outputs are connected to the ADC sync inputs. TMRA Channel 3 output is connected to

SYNC0 and TMRA Channel 2 is connected to SYNC1. SYNC0 is the master ADC sync input that is used

to trigger ADCA and ADCB in sequence and parallel mode. SYNC1 is used to trigger ADCB in parallel

independent mode. These are controlled by bits in the SIM Control Register; see Section 6.3.1.
