[原创] Microsemi ProASIC3L低功耗闪存FPGA解决方案

Microsemi公司的ProASIC3L是采用Flash*Freeze技术的低功耗闪存FPGA器件,和通常等价的ProASIC3相比,动态功耗降低40%,静态功耗降低50%,核工作电压1.2V-1.5V,I/O电压低至1.2V,提供1kb可重新编程非易失性FlashROM以及基于时钟调节电路的锁相环(PLL),支持250k到3百万系统门,多达504kb真双端SRAM和620个用户I/O,支持高性能32位Cortex-M1处理器.主要用在低功耗数据传输和控制,如手持媒体,安全通信,无线电应用以及高性能手持设备,工业,测试,科学和医疗设备.本文介绍了ProASIC3L主要特性和优势,架构图,以及Cortex-M1使能ProASIC3L开发板M1A3PL-DEV-KIT主要特性,框图和电路图与PCB元件分布图.

The ProASIC3L family of Microsemi flash FPGAs dramatically reduces dynamic power consumption by40% and static power by 50% compared to the equivalent ProASIC3 device. These power savings arecoupled with performance, density, true single-chip, 1.2 V to 1.5 V core and I/O operation as low as1.2 V, reprogrammability, and advanced features.

Using Microsemi’s proven Flash*Freeze technology enables users to shut off dynamic powerinstantaneously and switch the device to static mode without the need to switch off clocks or powersupplies while retaining internal states of the device. This greatly simplifies power management on aboard done through I/Os and clocks. In addition, optimized software tools using power-driven layoutprovide instant push-button power reduction.
