Table 2. MCF51JE256/128 Functional Units
Unit
Function
DAC (digital to analog converter)
Used to output voltage levels.
12-BIT SAR ADC (analog-to-digital
converter)
Measures analog voltages at up to 12 bits of resolution. The ADC has
up to 12 single-ended inputs.
PDB (Programmable Delay Block)
Precisely trigger the DAC FIFO buffer.
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 the ColdFire 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.
SCI1, SCI2 (Serial Communications
Interfaces)
Serial communications UARTs capable of supporting RS-232 and LIN
protocols.
SIM (system integration unit)
