Cypress提供一系列无线解决方案，能满足射频控制(R/C)发烧级模型和R/C玩具的要求。下面的功能框图展示了Cypress采用WirelessUSB 2.4GHz收发器和PSoC / enCoRe MCU的解决方案。该框图还展示了解决方案各个模块/组成部分的功能。

射频控制(R/C)模型是自供电型模型汽车、卡车、飞机、轮船等。它们可以通过专用的发射器进行远距离控制。

除了一系列射频产品，Cypress还提供可编程片上系统(PSoC)器件。这些器件内置了一些模拟模块，例如模数转换器(ADC)、数模转换器(DAC)、脉宽调制器(PWM)、比较器等。它们非常适合用在 R/C模型或 R/C玩具中，用于处理电机控制、射频控制等功能。Cypress 还能提供低功耗enCoRe系列MCU，用于R/C玩具或用作远程控制器。

Cypress 的WirelessUSB射频器件、PSoC和enCoRe MCU 组成了完整的解决方案，能满足任何R/C模型或R/C玩具制造商的要求。

PRoC-LP Star:enCoRe II + WirelessUSB-LP Star

DESIGN CONSIDERATIONS

Radio-controlled (or R/C) models are self-powered model cars, trucks, planes, boats etc. that can be controlled from a distance using a specialized transmitter.R/C models are commonly grouped into grades as follows:

Hobby grade models

Have superior performance, better handling, longer life

Have accessories / upgrades available for several years after initial manufacturing

Often used in professional events

Available in easy to assemble kits or as “Ready-To-Run” (RTR) models requiring minimum to no assembly at all

Toys grade models or R/C Toys

Performance and lifespan varies with price

Pre-assembled and bought off the shelf

Cheaper and easier to operate than hobby grade models

Key design considerations for R/C models and high end R/C toys with respect to radios are as follows:

Higher range (distance between remote and model) for outdoor use

Minimizing crashes by avoiding interference from other devices

Prevention of cross talk when multiple models are operated within transmission range of each other

Avoiding multi-path interference (reflected signal fading) and polarization blind spots (signal loss when antenna is directly pointed at transmitter)

Cypress’ WirelessUSB products are built to suit these needs:

WirelessUSB-LP has a maximum TX power of +4dBm and an inbuilt Low Noise Amplifier enabling higher range (~100m).Moreover WirelessUSB-LP has a dedicated pin for easy control of external power amplifiers

Sub-1GHz bands are getting crowded and more susceptible to interference, WirelessUSB devices operate in the 2.4GHz ISM band

DSSS and channel hopping ensure best-in-class interference immunity and superior co-location capability; leading to lower chances of cross talk between models and fewer crashes

Use of multiple WirelessUSB transceivers on model or car with different antenna orientations eliminates multi-path interference and polarization blind spots

WirelessUSB-NL radio provides channel hopping based interference avoidance and ultra low power consumption, enabling low cost R/C toys manufacturers to get good performance at competitive prices.

Together with this portfolio of radios Cypress also provides Programmable System-on-Chip (PSoC) devices which have inbuilt analog blocks like Analog to Digital Convertors (ADCs), Digital to Analog Convertors (DACs), Pulse Width Modulators (PWMs), Comparators etc.These are ideal for use on the R/C model or R/C toy side to handle functionality like motor control, radio control etc.Cypress also provides the low power enCoRe series of MCUs which can be used on R/C toys or remote controller side.

Cypress’ WirelessUSB radios, PSoCs and enCoRe MCUs provide a complete solution to suit the needs of any R/C model or R/C toys manufacturer.

CYPRESS公司简介

Cypress公司是一家知名的电子芯片制造商，其中文名称为——赛普拉斯。 赛普拉斯在纽约股票交易所上市，在数据通信、消费类电子等广泛领域均提供芯片解决方案。

Cypress半导体公司生产高性能IC产品，用于数据传输、远程通讯、PC和军用系统。公司1982年成立，是一家国际化大公司。目前约有人员3000人，已经在全球建立了销售网络。公司总部设在美国加州San Jose。

公司的生产据点包括：

据点1：在加州圣约瑟市，是公司的第一个工厂和现在的研发基地。

据点2：在德克萨斯州Round Rock，1986年建立，生产SRAM产品。

据点3：Cypress Semiconductor Philippines Inc.(CSPI),是公司在菲律宾设立的组装、检测工厂，1996年投入生产，此外在印尼也有同类的工厂。

除了在加州硅谷拥有最早的设计中心之外，公司在美国的科罗拉多州、华盛顿、俄勒冈州、明尼苏达州、肯塔基、新汉普郡及英格兰、爱尔兰、菲律宾也设有设计工厂。1987年开始采用0.8微米CMOS工艺技术，1992年转移至0.65微米，不久将引入0.21微米工艺，现在70%以上的产品使用0.35微米或以下的工艺制造的。目前，Cypress半导体公司的新战略是瞄准大容量半导体市场，为此采取了一系列新步骤：将产品组装、检测转移至海外，减少产品/封装数量，改良生产设备等，以提高生产效率、缩短产品上市周期。
