ISSI's Portfolio of Mobile DDR DRAMs

ISSI has a wide offering of mobile DDR DRAMs (also known as LPDDR) from 32Mbit to 2Gbit. The industry originally developed mobile DDR products for the hand-held consumer segment, but these DRAMs have been adopted into industrial, automotive and networking applications, have broad support from mainstream microprocessors. ISSI is sampling the following products this quarter, ramping into mass production Q3.

Visual Alarms with an ISSI HBLED Driver

For many years the dreaded, high-pitched audible alarm signal has been the primary warning of a fire. However, in many cases, a visual signal is a critical alert for those who are deaf or hard of hearing, work in a noisy environment, or those who cannot bear the high-pitched decibels. For these people and others, help is on the way. Recently, governments around the world have begun mandating that audible alarms be supplemented with a visual alarm signal. Many of these initiatives will begin implementation this year. The challenge for the alarm system engineers is to design a device that efficiently produces an intense light using minimal circuitry, while operating from a back-up battery. In addition, the complete solution must be at a minimal increase to system cost. Fortunately, ISSI has the perfect component to solve the problem. An ISSI HB LED driver, the IS31LT3360 simplifies the visual alarm design, requiring only six components, including the IC. Designs using this device will be capable of efficiently driving a single LED--or even multiple LEDs—connected in series at up to 1.2A. When used in an alarm system, the microcontroller can easily enable or disable the IS31LT3360 via a single control pin (ADJ) so it will generate the visual alarm notification when required. The microcontroller can also adjust the light brightness of the IS31LT3360 by applying a PWM control to the ADJ. Example schematics are included in the datasheet. With the new legislation in place, ISSI expects our customers to be looking for the most cost-effective and simple solution to add visual signaling. ISSI also offers audio amplifiers such as the IS31AP4990 that can address the audio portion of the alarm signaling.

 Implementing a Capacitive Swipe Switch

Switches have been around since the start of electricity and to envision a world without switches seems almost senseless. Switching on and off is simple, but remains an integral component in all electronic circuitry. Electronic switches such as capacitive touch sensors are becoming the technology of choice for modern applications. The requirement for invariable functioning of capacitive sensors is imperative. Sophisticated product specifications require better sensitivity, higher levels of safety, improved immunity against aqueous substances and ultra-low power consumption, especially for portable and battery operated devices.
With modern day capacitive sensing solutions the designer has the choice of implementing either a self- or projected capacitive sense electrode.
