Description
The Atmel
®
AT24C01C/02C provides 1024/2048-bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 128/256 words of eight
bits each. Both devices include a cascading feature that allows up to eight devices to
share a common 2-wire bus. These devices are optimized for use in many industrial
and commercial applications where low power and low voltage operation are essential.
The AT24C01C/02C are available in space saving 8-lead PDIP, 8-lead JEDEC SOIC,
8-lead TSSOP, 8-lead UDFN
, 5-lead SOT23, and 8-ball VFBGA packages. In addition,
the entire family operates from 1.7V to 5.5V V

4. Pin Description
Serial Clock (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge
clock data out of each device.
Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open drain driven and may be
wire-ORed with any number of other open drain or open collector devices.
Device/Page Addresses (A
2
, A
1
, A
0
): The A
2
, A
1
, and A
0
pins are device address inputs that are hard wired for the
AT24C01C/02C. As many as eight 1-Kbit or 2-Kbit devices may be addressed on a single bus system. See Section 7.
“Device Addressing” on page 9 for more details.
Write Protect (WP): The AT24C01C/02C have a Write Protect pin that provides hardware data protection. The Write
Protect pin allows normal read/write operations when connected to ground (GND). When the Write Protect pin is
connected to V
CC
, the write protection feature is enabled and operates as shown below in Table 4-1.

      资源摘要:MATLAB代码:多微电网优化调度关键词:多微电网 优化调度参考文档:《面向配电网的多微电网协调运行与优化》基本复现仿真平台: MATLAB主要内容:代码主要做的是面向配电网的多微电网协调运行与优化，把多微电网看成一个整体参与配电网优化调度，并针对峰平谷三个时段的不同电价提出了各时段的多微电网联合协调调度策略，并根据该调度策略建立数学模型，以多微电网系统总运营成本最小胃目标函数进行优化。出图效果也非常清楚，具体可以看下图。

      资源摘要:四轮分布式驱动车辆复合制动分层控制，分布式驱动电动汽车复合制动控制策略，建立七自由度整车模型、魔术轮胎模型、电机模型、电池模型，研究上下层机电复合控制策略。不仅前轮会有再生制动力，同样后轮也会有再生制动力，因此在上一节所述的三种制动力分配基础分析可以得出结论：前、后轮均能进行再生制动的复合制动系统，应使实际制动力分配曲线接近 I 曲线，并且通过合理调整液压制动力与回馈制动力的分配关系，在保证制动稳定性的同时，实现能量回收的最大化。第一步是进行汽车前、后轮间制动力分配，为了保证制动稳定性，要使得前、后轮制动力尽可能的符合 I 曲线；第二步是在第一步的基础上进行电、液制动力分配，为了保证能量回收率，应当使电机制动占尽可能多的份额。制动力上层控制器保证前、后轮滑移率相同，从而最大程度上保证车辆的制动稳定性，即不会出现前轮或后轮提前抱死的制动失稳工况。Braking torque when ABS：紧急制动时的前后轴制动力分配Braking torque in normal：一般制动时的前后轴制动力分配ABS or normal braking judge：紧急制动和一般制动判别
