M2M Development Platform for CDMA
Microchip Technology released DM320017, a new Verizon Wireless Certiied Machine-
to-Machine (M2M) Development Platform for CDMA. The full-featured platform (de-
veloped by Twisthink, LLC, a Microchip Authorized Design Partner) enables custom
embedded irmware application development on the PIC32, 32-bit microcontroller,
with local-area and remote cellular connectivity. The platform is pre-certiied on the
Verizon Wireless network, with two-way communication capability...

Next-Generation Thin Wafer IGBT
Inineon’s TRENCHSTOP5 IGBTs are the next generation of thin wafer IGBT (Insulated
Gate Bipolar Transistor) that feature signiicantly lower conduction and switching
losses compared to currently leading solutions. There is no other IGBT on the market
that can match the performance of the TRENCHSTOP5. These are designed for ap-
plications where switching >10kHz. The wafer thickness has been reduced by >25%,
which enables a dramatic improvement in both switching and conduction losses,
while providing a breakthrough voltage of 650V...

LIN Transceiver for SAE J2602 Standard
The MLX80020BB device is a physical layer device for a single wire data link capable
of operating in applications using baud rates of 10.4kBd. MLX80020BB is compatible
to SAE J2602 speciications used by GM and Ford. Because of the very low power
consumption of the MLX80020 in the sleep mode, it is suitable for ECU applications
with hard standby current requirements. The implemented high resistive termination
in sleep mode as well as the driving capability of the INH pin allows a comfortable
handling of LIN short circuits to GND...

300VAC Subminiature Time-Lag TE5 Fuse
The 369 series in its compact TE5 package provide an ideal alternative over glass
cartridge fuses in electronic ballast application, especially where PCB board space is
limited. The 369 series radial leaded fuses are rated at 300VAC as compared to exist-
ing competition in the market which are rated at 250VAC. In addition, it can either
be directly soldered or used in conjunction with plug-in holder. And its Tape and
Ammo-packaging are ideal for high volume production...

CTCSS Codec with Voice Signal Circuit
The AK2345 is an IC which supports CTCSS (Continuous Tone Controlled Squelch
System), compatible with TIA/EIA-603 standard. A single CTCSS may be selected from
among 50 different frequencies within a range of from 67 to 254.1 Hz. By sending that
CTCSS simultaneously with the voice signal during transmission , and by setting the
audio circuit so that it operates only when a CTCSS of that frequency is detected, it is
possible to have multiple communication on the same radio frequency...

Microstepping DMOS Driver with Translator
The A3979 is a complete microstepping motor driver with built-in translator, de-
signed as a pin-compatible replacement for the successful A3977, with enhanced
microstepping (1/16 step) precision. It is designed to operate bipolar stepper motors
in full-, half-, quarter-, and sixteenth-step modes, with an output drive capacity of
up to 35 V and ±2.5 A. The A3979 includes a ixed off-time current regulator that has
the ability to operate in Slow, Fast, or Mixed decay modes. This current-decay con-
trol scheme results in reduced audible motor noise, increased step accuracy, and
reduced power dissipation...

3A 1ch Buck Converter
Output 3.0A and below High Eficiency Rate Step-down Switching Regulator
Power MOSFET Internal Type BD9876EFJ mainly used as secondary side Power sup-
ply, for example from ixed Power supply of 12V, 24V etc, Step-down Output of
1.2V/1.8V/3.3V/5V, etc, can be produced. This IC has external Coil/Capacitor down-
sizing through 300kHz Frequency operation, inside Nch-FET SW for 45V “withstand-
pressure” commutation and also, high speed load response through Current Mode
Control is a simple external setting phase compensation system, through a wide
range external constant, a compact...

Low-Power Mobile Stereo Codec
CS42L73 is a highly integrated, low-power smart audio codec that serves as a mobile
audio distribution network incorporating two stereo digital/analog converters (DACs)
and a stereo ADC with ground centered headphone, line and speaker ampliiers for
smartphone and portable applications. Three asynchronous bidirectional serial ports
with integrated asynchronous sample rate converters (ASRCs) that accept a wide
range of incoming audio sample rates can be used to feed the integrated digital
mixing engine, which is the heart of the CS42L73...

Compact DC Panel Mount Voltmeter
Murata announced the compact DMR20-10-DCM “nanoMeter” self-powered auto-
ranging DC voltmeter designed for mounting in an industry-standard “oiltight” 30
and 30.5 mm / 1.2 inch round panel cutout. Occupying minimal space, the round
voltmeter has a 7.6mm / 0.3 inch four-digit LED display and is self-powered. The
connection to the +6 to +75 VDC supply to be monitored is all that is required for full
operation. There is no additional components or separate power supply is required
for the DMR20, making it extremely easy to add into virtually any equipment using a
DC supply or batteries...

Power-Eficient Cortex-A9 Processor
Cortex-A9 is available as either synthesizable or hard-macro implementations. ARM
Physical IP is available to support a synthesizable low optimized for lowest power or
highest performance, as well as a choice of hard-macros reducing risk and shorten-
ing time-to-market to a minimum. Enhanced ARM Graphics IP like Mali-624 as well
as ARM System IP such as CoreLink NIC-400/301 network interconnect and CoreLink
DMC-342 dynamic memory controller allow a rapid system design...
