SEGGER Introduces new “NAND-Flash EVAL” and Test Board

SEGGER Microcontroller has introduced a new tool for engineers to evaluate and test SEGGER’s NAND flash driver as well as the USB stack (emUSB) and the embedded file system (emFile) with various NAND flash memory to find the perfect fit for their upcoming project. The NAND-Flash EVAL board is equipped with a 48-pin TSOP socket for standard NAND flash memory and an Atmel® SAM3U ARM-based microcontroller (MCU). The MCU is preprogrammed with an application that automatically formats an unformatted NAND flash memory and runs a performance test. Afterwards the board behaves like a USB memory stick.

The engineer can use the board to test different flash memory and select the silicon he needs for his application without soldering or code creation. Of course the board also allows testing of custom code.

The SEGGER emFile NAND-driver is optimized for very high performance using minimum amount of RAM. With this hardware and the flash memory delivered with it. Write performance is 4.2 MB/s, read performance is 6.4 MB/s. The driver protects data from an unexpected reset, and uses wear-leveling to maximize the life of the NAND flash memory.

The software running on the NAND-Flash EVAL is delivered as a binary image for easy evaluation. This software is also included as a full development project for further modification and testing. The application layer of the project is left in source form and library evaluation versions of emFile, which include; the high performance NAND-driver, emUSB-Device with MSD class, and the extremely fast SEGGER embOS (RTOS). The engineer can program the NAND-Flash EVAL via USB or via JTAG/SWD debug interface. This permits the engineer to create and run their own applications on the board. The standard debug interface is accessible by a debug emulator such as the industry leading SEGGER J-Link (sold separately).

The Atmel SAM3U is based on the industry-standard ARM® Cortex™-M3 core. The MCU offers very high system-level integration, including an on-chip high-speed USB Device Controller with transceiver, PLL and NAND flash interface. The high level of integration in the Atmel SAM3U enabled SEGGER to build the NAND-Flash EVAL board as a two-chip system.

“The NAND-Flash EVAL board is a unique and efficient way to test and verify design decisions for software and hardware at very early stages of your development projects”, says Dirk Akemann, Marketing Manager at SEGGER.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
