ALTERA Naming Rules Cyclone Series

之所以因为购买错类型的元器件而造成退货纠纷或业务损失，是因为采购或销售人员对芯片命名规则了解不够，收到的芯片类型不够齐全。相关工作人员对此并不了解。FPGA 高性能组件通常更昂贵。如果你弄错了，损失会更大。今天我们用一张表格来分析ALTERA Cyclone系列大部分芯片的命名规则。和我们将讨论为什么 Altera Cyclone 系列被中国芯片取代的可能性很高？

ALTERA CYLCONE 系列的大多数型号由以下命名的模块组成。家庭系列系列特点。这里需要注意的是，并不是所有的产品都是由系列特性、器件类型、成员代码、支持快速开机功能等组成的。请注意，此功能并非对每个人都可用。每个型号都有它、封装引脚号、温度、速度和封装信息。

EP4CE40F29C8N

我们先来看看这个模型。EP4C 是 Cyclone弘玑的第四代产品，属于家族系列。E 表示此模型的特征。E 表示增强的 logic 和 memory。（增强的 logic/memory 是指增强的 logic/memory），40 个成员的代码对应逻辑单元的数量（通常用逻辑单元数量千分之几以上的数字命名，例如，如果有 10,320 个逻辑单元，则使用 10 作为代号），F 代表封装类型 FBGA，29 代表引脚号为 780 个引脚， C 代表 0 至 85°C 的商业温度，8 代表速度等级，N 代表无铅。

EP3C25F324C7N

让我们看一下另一个模型。EP3C 表示 Cyclone 的第三代产品对应家族系列。25 是与逻辑单元数对应的成员代码。F 是包类型。这是 FBGA 软件包。324 是引脚数。C 代表工作温度。7 代表速度等级，N 代表无铅。

EP2C70AF324C7ES

Let’s take a look at the EP2C70AF324C7ES model. First of all, EP2C is the second-generation product family series of Cyclone. This model has no series features. Here, 70 is the device type, A is fast turn-on (POR time), F is package type FBGA, 324 is the number of pins, C is the operating temperature, which represents the commercial temperature 0 to 85℃, 7 is the speed grade, and ES represents the engineering sample.

Why is it said that the Altera Cyclone series has a higher chance of replacing Chinese chips?

There are two main reasons:

1: Opponents have given Chinese chips opportunities. After Altera was acquired by Intel, it prefers to make high-profit products.Gradually looking down on pure FPGA series with lower technical thresholds, coupled with the opportunity of shortages in the past two years, users urgently need other cheaper alternatives, and Chinese domestic chip products that are compatible with the Altera Cyclone series of FPGAs have begun to appear.

2: In fact, FPGA started in the 1990s and was one of the first categories of processor chips to be replaced by Chinese chips. It was not used in the past. China's FPGA is now gradually entering the industrial, communications and automotive markets.
