The Kindle 3 utilizes a Freescale i. MX353 applications processor, Freescale MC13892 power management chip, Epson EINK controller and Samsung DRAM and Flash. Other hardware changes include a larger 1750 mAh lithium polymer battery, AnyDATA DTP-600W 3G GSM modem and Atheros AR6102G 802.11bg WiFi chip.

kindle 3的CPU与2代一致，是飞思卡尔i.MX35系列的i.MX353，为ARM11系列的下一代产品，该款处理器运行频率为532MHz，目标锁定基于显示屏的高性价比系统。

• Freescale i. MX353 处理器，频率532MHz（Freescale，飞思卡尔，原摩托罗拉半导体部，主要提供嵌入式处理产品）；
• Freescale MC13892 电源管理IC；
• 台北精工爱普生e ink面板控制器（Seiko Epson公司是E Ink公司的e ink面板控制器开发商）；
• 三星内存（Samsung是全球最大的内存颗粒供应商，2010年第2季DRAM市场占有率33.9 %，Kingston因其密切合作而出名）；
• 1750毫安锂聚合物电池；
• AnyDATA DTP-600W 3G卡，应该是基于WCDMA的（AnyDATA是一家美国的无线通信模块设计公司，其CDMA无线模块是目前同类型产品中体积最小，速度最快，品种最齐全的）；
• Atheros的WiFi网卡（Atheros是全球最大的无线网卡芯片供应商，强过Csico？）。

MC13892 is a Power Management and User Interface component for Freescale’s i.MX51, i.MX37, i.MX35 and i.MX27 application processors, targeting personal media players and personal navigation devices.

The MC13892 integrates many discrete functions into one IC. It incorporates, a battery charging system including USB charging and wall charging, 10 Bit ADC plus Coulomb counter for battery chargefuel gauging, 4 adjustable buck converters for powering processor core and memory, and 12 adjustable LDO’s with internal/external pass devices. It also includes 2 boost converters for LCD backlighting and RGB LED driving, serial backlighting drivers for display, and keypad and RGB LED drivers.

The MC13892 incorporates power control logic with processor interfacing and event detection, Real time clock and critical oscillator circuitry with coin cell backup and support, for external secure RTC on a companion processor IC device. It incorporates SPI and I2C interfacing. Touch Screen interface circuitry – all incorporated into a highly integrated mixed signal IC. It is intended for interfacing with Freescale i.MX processors or any other device – system needing a highly integrated, bi-directional power management, I/O, and communications device.

kindle 3为什么可以待机一个月，除了e ink本身的耗能特性外，可能最主要还是要归功于Freescale MC13892电源管理IC，这个IC配合一些Freescale’s i.MX多媒体处理器，应用于媒体播放器和导航设备。我想，市场上应该会有很多的产品采用飞思卡尔的这个方案吧。
