Table 2. MCF51MM256/128 Functional Units
Single-pin high-priority interrupt (part of the V1 ColdFire core).
Supports standard IIC communications protocol and SMBus.
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 — The measurement engine PDB is used to
precisely trigger the DAC and the ADC modules to complete sensor
biasing and measuring.
Provides expansion capability for off-chip memory and peripherals.
Supports the USB On-the-Go dual-role controller.
Provides clocking options for the device, including a phase-locked loop
(PLL) and frequency-locked loop (FLL) for multiplying slower reference
clock sources.
Provides single pin debugging interface (part of the V1 ColdFire core).
Executes programs and interrupt handlers.
Analog comparators for comparing external analog signals against
each other, or a variety of reference levels.
Software Watchdog.
High-speed CRC calculation.
Provides debugging and emulation capabilities (part of the V1 ColdFire.
core)
Provides storage for program code, constants, and variables.
Controls and prioritizes all device interrupts.
Keyboard Interfaces 1 and 2.
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.
The Voltage Reference output is available for both on- and off-chip use.
Provides stack and variable storage.
Allows for I/O port access at CPU clock speeds. RGPIO is used to
implement GPIO functionality.
Infrared output used for the Remote Controller operation.
