STR9 ARM9 boosts embedded Flash and saves part count in connected applications

ST has increased the on-chip Flash capacity of its STR91xFA ARM966E-S based MCU family by introducing 1.1 Mbyte and 2.1 Mbyte variants, delivering higher memory density than any other ARM9, or ARM7-TDMI, based standard MCU currently available. The new devices are pin- and function compatible with existing 288 Kbyte and 544 Kbyte versions in LQFP-80, LQFP-128 and BGA-144 packages, allowing engineers to scale designs easily without incurring expensive changes to their circuit boards.

MDmesh™ II and FDmesh™ II - high-efficiency power converters with high-current power MOSFETs

Fundamental in addressing the efficiency requirements of new SMPS and inverters, the new very high current 600 V MDmesh II devices address high-efficiency requests. In terms of conduction losses, they provide exceptionally low RDS(on) in TO-247 and Max247 packages and a good power handling capability. In terms of the total switching losses, particularly with the new 600 V FDmesh II fast diode version, they provide customers with a reduced trr, Irrm and an enhanced dynamic dv/dt. More

TSC101 - high-side current-sense amplifier

The TSC101 is the first device of a new standard family: high-side current-sensing amplifiers. The TSC101 measures very small voltage drops on a high-side shunt resistor, and using an internally fixed gain, amplifies the difference into a ground-referenced output voltage. The device is housed in a tiny SOT23-5 package. More

L675x – innovative power management for the latest Intel CPUs

The new L675x PWM multi-phase controllers, coupled with L674x power MOSFET drivers, allow the design of very flexible solutions for power management of the latest processors in PC, server and workstation motherboards. More

STw5210 - Enjoy music longer and better

The STw5210 is a very high performance 24-bit audio DAC (digital to analog converter) that is intended for the mobile music market. It provides 103dB signal-to-noise ratio through the whole audio path, while also embedding the company’s innovative PTETM Playback Time Extender function to reduce power consumption of the platform. Simplifying the system design, the DAC can be directly connected to the battery, and drives a headset without coupling capacitor thanks to its true-ground headset amplifier. More

STWD100 – low-power watchdog circuit with Chip-Enable pin

The new STWD100 is a low-power watchdog circuit that includes an active-low enable pin. This pin is handy for momentarily disarming the device. Two examples of when this important feature is required are in-system programming and slow booting applications. When the enable pin is left unconnected, the part is enabled. More

EMIF01-1003M3 – smallest integrated EMI filter for keypad and side keys

The EMIF01-1003M3 is housed in a 1 x 0.6 mm DFN package and provides up to -25 dB attenuation at 900 MHz together with 15 kV ESD protection. The device features 100 ohm serial resistance and 30 pF line capacitance, in a 0.6 mm² package. As a result, using the EMIF01-1003M3 to filter and protect a cellular phone keypad saves 55% board space compared to a discrete solution with R, C and ESD diodes. The EMIF01-1003M3 is ideally suited for use in mobile phones, portable MP3 players, and camera applications.More

ST1S09 - 2 A, synchronous step-down DC-DC converter with Inhibit or Power Good

The ST1S09 is a 1.5 MHz PWM, synchronous step-down DC-DC converter with soft-start and internal compensation. Although maintaining the same tiny DFN6-3x3 package and pin configuration as the ST1Sx series, it is able to provide 2 A max output current and with the power-good feature for system monitoring.

LRi2K, low cost tags - fully compliant to the RFID standards - offer high-speed capability and unrivaled secured reading range

The LRi2K family is a best- in-class, true 2048-bit EEPROM user memory tag IC at 13.56 MHz with 64-bit UID, EAS through AFI and kill command for privacy. It is fully compliant and interoperable with ISO 15693 and ISO 18000-3 mode 1 for tracking applications requiring both data storage and security. This family is particularly suited for access control, library automation, and supply-chain management, as well as for anti-counterfeiting of sensitive products, such as pharmaceuticals and high-value items.
