MCF51QU32VFM

Description

MCF51QU32VFM are 32-bit microcontrollers. Freescale ColdFire+ 32-bit MCUs are built from the ColdFire V1 core and enabled by innovative 90 nm thin-film storage (TFS) flash technology with 32 KB of FlexMemory (2 KB of EEPROM). The portfolio is defined by five families that scale from 32 to 256 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 capabilities, hardware encryption, an innovative touch-sensing interface and more. These key features make ColdFire+ MCUs ideal for portable handheld devices, wireless nodes, peripherals that require device authentication, building control security pads and advanced remote control devices.
