HOT!!! ColdFire+ Overview

Freescale’s ColdFire+ 32-bit microcontrollers (MCUs) are enabled by innovative 90nm thin-film storage (TFS) flash technology with 32 KB of FlexMemory (2 KB of EEPROM). The portfolio is defined by six families (MCF51QU, MCF51QH, MCF51QF, MCF51QM, MCF51JU and MCF51JF) that scale from 32 KB to 160 KB 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.

Targeted Applications

· Portable hand-held devices

· Wireless nodes

· Peripherals that require device authentication

· Building control

· Security pads

· Advanced remote control devices

· MP3 player accessories

Key Features and Benefits of ColdFire+

The feature superset of the six pin- and software-compatible families includes:

· Innovative FlexMemory enabling up to 2 KB of enhanced EEPROM or additional 32 KB of flash

· 10 flexible low power modes, ideal for extending battery life: 150 μA/MHz in run mode, 500 nA/MHz in lowest power mode

· 16-bit ADC and 12-bit DAC to provide flexible and powerful mixed signal capabilities
