Overview
The MCF51JM128 is part of the Freescale
Flexis™ microcontroller series, the connection
point on the Freescale Controller Continuum
where 8-bit and 32-bit compatibility becomes
a reality. The Flexis series of devices includes
complementary families of 8-bit S08 and 32-bit
V1 ColdFire
®
microcontrollers that have a
common set of peripherals and development
tools to deliver the ultimate in migration flexibility.
The 32-bit MCF51JM128 device further
extends the low-end of the ColdFire
embedded USB controller family with up
to 128 KB of flash memory, a full-speed
USB 2.0 controller with host, device and
On-The-Go (OTG) support, an integrated
CAN module and a 12-channel, 12-bit
analog-to-digital converter. The ColdFire JM
family also features a hardware cryptographic
acceleration unit (CAU), a random number
generator accelerator (RNGA) and several
system protection features such as low
voltage detect and a Computer Operating
Properly (COP) module.
The JM128 devices, like the other USB
microcontrollers in the Controller Continuum,
are supported by the Freescale USB-LITE
Stack by CMX. This complimentary*** USB
stack provides support for certain HID, CDC
and mass storage classes. Source code for
the complimentary stack is available. The
MCF51JM128 is software compatible with
other devices in the Controller Continuum,
providing a direct migration path to higher
performing USB microcontrollers.
