The MCF51JM family is part of the Freescale Flexis microcontroller series, the connection point on Freescale"s 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.
- Dual-role USB OTG device supports USB in either device, host or OTG configuration
- Controller area network (CAN)
- Cryptographic acceleration unit (CAU)
- ADC 12-channel, 12-bit resolution
- Random number generator accelerator (RNGA)
- Low-voltage detection and a COP module
- 2 serial communications interface (SCI)
- 2 serial peripheral interface (SPI)
- 2 I²C
- Two 16 bit timers, 2/6-channel
- Up to 16 keyboard interrupts (KBI)
- Up to 66 general-purpose input/outputs (GPIOs)
