The MCF51JM family is part of the Flexis® microcontroller series, the connection point on Our 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 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 (ADC). 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.
