The following table describes the functional units of the MCF51MM256/128.
Table 2. MCF51MM256/128 Functional Units
Unit
Function
Measurement Engine
DAC (digital to analog converter) — Used to output voltage levels.
16-BIT SAR ADC (analog-to-digital converter) — Measures analog
voltages at up to 16 bits of resolution. The ADC has up to four differential
and 8 single-ended inputs.
OPAMP — General purpose op amp used for signal filtering or
amplification.
TRIAMP —- Transimpedance amplifier optimized for converting small
currents into voltages.
Measurement Engine PDB — Themeasurement engine PDB is used to
precisely trigger the DAC and the ADC modules to complete sensor
biasing and measuring.
Mini-FlexBus
Provides expansion capability for off-chip memory and peripherals.
USB On-the-Go
Supports the USB On-the-Go dual-role controller.
CMT (Carrier Modulator Timer)
Infrared output used for the Remote Controller operation.
MCG (Multipurpose Clock Generator)
Provides clocking options for the device, including a phase-locked loop
(PLL) and frequency-locked loop (FLL) for multiplying slower reference
clock sources.
BDM (Background Debug Module)
Provides single pin debugging interface (part of the V1 ColdFire core).
CF1 CORE (V1 ColdFire Core)
Executes programs and interrupt handlers.
PRACMP
Analog comparators for comparing external analog signals against
each other, or a variety of reference levels.
COP (Computer Operating Properly)
Software Watchdog.
IRQ (Interrupt Request)
Single-pin high-priority interrupt (part of the V1 ColdFire core).
CRC (Cyclic Redundancy Check)
High-speed CRC calculation.
DBG (Debug)
Provides debugging and emulation capabilities (part of the V1 ColdFire.
core)
FLASH (Flash Memory)
Provides storage for program code, constants, and variables.
IIC (Inter-integrated Circuits)
Supports standard IIC communications protocol and SMBus.
INTC (Interrupt Controller)
Controls and prioritizes all device interrupts.
KBI1 & KBI2
Keyboard Interfaces 1 and 2.
LVD (Low-voltage Detect)
Provides an interrupt to theColdFire V1 CORE in the event that the
supply voltage drops below a critical value. The LVD can also be
programmed to reset the device upon a low voltage event.
VREF (Voltage Reference)
The Voltage Reference output is available for both on- and off-chip use.
RAM (Random-Access Memory)
Provides stack and variable storage.
RGPIO (Rapid General-purpose
Input/output)
Allows for I/O port access at CPU clock speeds. RGPIO is used to
implement GPIO functionality.
