江苏宏云陶建平:MCU+DSP芯片架构用于无线充电

l2源yuan 来源:电子发烧友原创 作者:肖青梅 2018-05-08 16:16 次阅读

【导读】:2018年4月27日,在电子发烧友主办的无线充电研讨会上,来自江苏宏云技术有限公司董事长兼总经理陶建平,从三方面入手,分享了基于MCU+DSP芯片方案。

宏云核心竞争力

拥有8/16/32位单片机(MCU)设计技术,陶建平说宏云切入无线充电市场的时间不长,但是核心竞争力已经形成,设计有自定义指令集的数字信号处理器(DSP),是宏云在市场竞争中最大的差异化优势。

基于DSP架构的处理器可以采用单个或多MAC运算单元。比如,JMT018内核是当前世界上最小的DSP芯片,单MAC运算和除法指令等,16比特指令编码,且大多指令为单周期指令,其极低的功耗和通用的指令,非常适合智能硬件,可穿戴设备的应用。

DSP产品规划

宏云最突出的是特色是,拥有自定义指令集数字信号处理器(DSP)设计技术,公司先后建立了单核MCU和MCU+DSP双核平台,在这两个平台上推出了两个系列的MCU SOC芯片。

宏云的产品规划

陶建平介绍,宏云的产品规划主要应用于,电机的FOC正弦波矢量控制、无线充电和快速充电管理、麦克风阵列等方向。

在会上陶建平为我们重点分享了,8/16位MCU芯片JMT1808/1808R,采用8bit MCU和16bit DSP双核架构。73MHz的51+DSP,外设也非常丰富如:PWM, ADC,内部运放,比较器等,加上内部集成有DSP核,因此性能不错,有工程师评价可直接替代TI的芯片,性价比非常高。

JMT1808(MCU+DSP)芯片架构

JMT1808内核的是73MHz(运行在eFlash下)的8051 MCU,其8051性能仅次于Silicon Labs,同时还内置了DSP内核,支持四则运算及Cordic,130多条DSP指令。 而在IO方面,同样支持多种通信接口,可满足电机控制物联网及可穿戴等诸多市场,JMT1808R(MCU+DSP)芯片架构运算能力非常强,而且想要省功耗,还可以分开运行的。

而无线充电管理芯片JMT1801ED则是在1808R的基础上开发的,这是一款基于JMT018-1MAC内核的芯片,采用的是MCU+DSP架构,支持无线充电联盟(WPC)的Qi 1.2标准,其DSP内核技术的软件平台,可实现高效的 PID 控制环路,通信协议的数字解调;可用于无线充电的定频,变频,调占空比,调压控制等控制方式; 支持外来物体检测(FOD),并且具有多种保护等特征。能够为移动设备(智能手机、平板电脑) 和工业设备等充电。

在实测当中,当用12W的功率给iPhone8充电的时候,效率可达82%,并且由于DSP是宏云自己的开发环境,客户可选择使用或者不使用,方案都是可定制的。

iPhone 8定频充电,电量从23%开始

无线充电应用方案

陶建平说宏云的无线充电应用方案均是建立在8051的开发环境下的,并且提供了经济版和钻石版两种选择。

第一种经济版定频-调压相对省钱,对于预算有限的厂家来说比较合适,基本实现了调压的目的,用料上能省则省。

定频-调压之经济板方案设计

第二种钻石版定频-调压的设计豪华很多,原材料更好,有一个用来调压的MOS,相对于经济版调压也更稳定,并且芯片管脚足够的话,可以做多线圈的。

最后陶建平说,DSP是宏云自由的开发环境,客户可以选择使用,并非强制使用。

关于江苏宏云

陶建平介绍江苏宏云成立于2012年,由曾任职世界著名通信和半导体公司经验丰富的IC设计团队,从事DSP芯片的研制,设计有自定义指令集的数字信号处理器(DSP)。

陶建平本人拥有丰富的IC设计经验,曾在美国摩托罗拉、飞思卡尔半导体、中兴美国等公司从事手机基带和应用处理器SOC架构设计工作15年,现任江苏宏运技术公司董事长兼总经理。

    信息描述The THS1009 is a CMOS, low-power, 10-bit, 8 MSPS analog-to-digital converter (ADC). The speed, resolution, bandwidth, and single-supply operation are suited for applications in radar, imaging, high-speed acquisition, and communications. A multistage pipelined architecture with output error correction logic provides for no missing codes over the full operating temperature range. Internal control registers allow for programming the ADC into the desired mode. The THS1009 consists of two analog inputs, which are sampled simultaneously. These inputs can be selected individually and configured to single-ended or differential inputs. Internal reference voltages for the ADC (1.5 V and 3.5 V) are provided. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application. The THS1009C is characterized for operation from 0°C to 70°C, and the THS1009I is characterized for operation from ...

    TLV1572 10 位 1.25 MSPS ADC 单通道 DSP/(Q)SPI IF S 极低功耗自动断电功能

    信息描述The TLV1572 is a high-speed 10-bit successive-approximation analog-to-digital converter (ADC) that operates from a single 2.7-V to 5.5-V power supply and is housed in a small 8-pin SOIC package.The TLV1572 accepts an analog input range from 0 to VCC and digitizes the input at a maximum 1.25 MSPS throughput rate. The power dissipation is only 8 mW with a 3-V supply or 25 mW with a 5-V supply. The device features an auto-powerdown mode that automatically powers down to 10 uA whenever a conversion is not performed. The TLV1572 communicates with digital microprocessors via a simple 3- or 4-wire serial port that interfaces directly to the Texas Instruments TMS320 DSPs and (Q)SPI compatible microcontrollers without using additional glue logic. Very high throughput rate, simple serial interface, SO-8 package, 3-V operation, and low power consumption make the TLV1572 an ideal choice for compact or remote high-speed systems.特性F...

    TLV1578 8 通道 10 位 1.25MSPS ADC,具有 8 通道输出、DSP/SPI、硬件可配置、低功耗

    信息描述The TLV1571/1578 is a 10-bit data acquisition system that combines an 8-channel input multiplexer (MUX), a high-speed 10-bit ADC, and a parallel interface. The device contains two on-chip control registers allowing control of channel selection, software conversion start, and power down via the bidirectional parallel port. The control registers can be set to a default mode by applying a dummy RD\ signal when WR\ is tied low. This allows the TLV1571/1578 to be configured by hardware. The MUX is independently accessible. This allows the user to insert a signal conditioning circuit such as an antialiasing filter or an amplifier, if required, between the MUX and the ADC. Therefore, one signal conditioning circuit can be used for all eight channels. The TLV1571 is a single channel analog input device with all the same functions as the TLV1578. The TLV1571/TLV1578 operates from a single 2.7-V to 5.5-V power supply. It accepts an ana...

Each device has a chip select (CS\), input-output clock (I/O CLK), data input (DATA IN) and serial data output (DATA OUT) that provide a direct 4-wire synchronous serial peripheral interface (SPITM, QSPITM) port of a host microprocessor. When interfacing with a TMS320 DSP, an additional frame sync signal (FS) indicates the start of a serial data frame. The devices allow high-speed data transfers from the host. The (INV CLK)\ input provides further timing flexibility for the serial interface. In addition to a high-speed converter and versatile control capability, the device has an on-chip 11-channel multiplexer that can select any one of eight analog inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic except for the extended sampling cycle,...

    TLV1570 10 位 1.25MSPS ADC 8 通道 DSP/(Q)SPI IF 可编程内部 基准、自动或 S/W 断电、极低功耗

    信息描述The TLV1570 is a 10-bit data acquisition system that combines an 8-channel input multiplexer (MUX), a high-speed 10-bit ADC, an on-chip reference, and a high-speed serial interface. The device contains an on-chip control register allowing control of channel selection, conversion start, reference voltage levels, and power down via the serial port. The MUX is independently accessible, which allows the user to insert a signal conditioning circuit such as an antialiasing filter or an amplifier, if required, between the MUX and the ADC. Therefore one signal conditioning circuit can be used for all eight channels.The TLV1570 operates from a single 2.7-V to 5.5-V power supply. The device accepts an analog input range from 0 V to AVDD and digitizes the input at a maximum 1.25 MSPS throughput rate. Power dissipation is only 8 mW with a 2.7-V supply or 40 mW with a 5.5-V supply. The device features an autopower-down mode that automatically ...

    TLC1550 10 位,164kSPS ADC,并行输出、直接 I/F 到 DSP/uProcessor、10 通道

    信息描述The TLC1550x and TLC1551 are data acquisition analog-to-digital converters (ADCs) using a 10-bit, switched-capacitor, successive-approximation network. A high-speed, 3-state parallel port directly interfaces to a digital signal processor (DSP) or microprocessor (µP) system data bus. D0 through D9 are the digital output terminals with D0 being the least significant bit (LSB). Separate power terminals for the analog and digital portions minimize noise pickup in the supply leads. Additionally, the digital power is divided into two parts to separate the lower current logic from the higher current bus drivers. An external clock can be applied to CLKIN to override the internal system clock if desired. The TLC1550I and TLC1551I are characterized for operation from –40°C to 85°C. The TLC1550M is characterized over the full military range of –55°C to 125°C.特性Power Dissipation...40 mW Max Advanced LinEPIC™ Single-Po...

    TLC1518 10 位 400kSPS ADC,具有串行输出、SPI/DSP 兼容接口、关断状态、8 通道

    信息描述The TLC1518 and TLC1514 are a family of high-performance, 10-bit, low power, 1.4 us, CMOS SAR analog-to-digital converters (ADC) which operate from a single 5 V power supply. These devices have three digital inputs and a 3-state output [chip select (CS\), serial input-output clock (SCLK), serial data input (SDI), and serial data output (SDO)] that provide a direct 4-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a DSP, a frame sync (FS) signal is used to indicate the start of a serial data frame. In addition to a high-speed A/D converter and versatile control capability, these devices have an on-chip analog multiplexer that can select any analog inputs or one of three internal self-test voltages. The sample-and-hold function is automatically started after the fourth SCLK edge (normal sampling) or can be controlled by a special pin, CSTART\, to extend the sampl...
