MCF5274VM166中文资料MCF5274 V2CORE 64KSRAM数据手册恩XP规格书

描述 Description

The MCF527x ColdFire® V2 integrated microprocessor combines high-integration and low-cost with a new level of performance on the popular ColdFire V2 core.
The combination of connection, protection and peripheral selection makes the MCF527 ideal for cost-sensitive, power-conscious applications requiring significant control processing for file management, connectivity, data buffering, user interface and signal processing. Additionally, the MCF5275 and MCF5274 are pin-to-pin compatible.
