The ColdFire+ MCF51Qx and MCF51Jx microcontroller (MCU) families from Freescale Semiconductor are built on 90 nm thin film storage flash technology with FlexMemory.
The ColdFire+ Qx and Jx families also have configurable embedded electrically erasable programmable read-only memory (EEPROM).
The devices are suited for industrial applications like building control (HVAC and light automation) and portable medical devices, as well as portable consumer devices. Capabilities include encryption and security, USB audio, capacitive touch interfaces and display technology.
ColdFire+ MCUs also have a touch sensing module, which, when combined with Freescale’s recently introduced Xtrinsic Touch-Sensing Software, simplifies touch key configuration by allowing multiple electrode array combinations.
The Qx and Jx portfolio includes the MCF51JF, MCF51JU, MCF51QM, MCF51QF, MCF51QH and MCF51QU families which are pin- and software-compatible.
The MCUs have 10 flexible ultra-low-power modes, a 16-bit ADC and 12-bit DAC, a cryptographic acceleration unit and random number generator for secure communication.
The Jx devices have integrated USB 2.0 full-speed device/host/OTG controller, supporting connection and battery charging via USB and a serial audio interface, providing direct interface to codecs and inter-IC sound (I2S) audio device
