MCF51xx ColdFire+ 32-Bit Microcontrollers

NXP Semiconductors MCF51xx ColdFire+ 32-Bit Microcontrollers (MCUs) are built from the ColdFire V1 core and enabled by innovative 90nm thin-film storage (TFS) flash technology with 32KB of FlexMemory (2KB of EEPROM). The portfolio is defined by six families that scale from 32KB to 128KB of flash, featuring incredible ultra-low power capabilities in small footprint solutions. ColdFire+ MCUs offer a rich combination of additive peripherals, including USB, high-performance mixed-signal, hardware encryption, an innovative touch-sensing interface (TSI) and more. These key features make ColdFire+ MCUs ideal for portable hand-held devices, wireless nodes, peripherals that require device authentication, building control security pads and advanced remote control devices.
