Flash-based Blackfin DSPs target automotive apps
eeProductCenter's Marty Gold says: "With an eye on the needs of automotive market, Analog Devices has launched its ADSP-BF539 and ADSP-BF539F Blackfin digital signal processors. Both processors provide CAN and MOST bus connectivity; the BF539F is the first Blackfin processor to incorporate flash memory."
» "Flash memory is what was needed."
» "Nice product."
» "Would like to see more information about power."
» "Putting flash inside a DSP is a natural. I don't know if TI has done it already, but this is important. The Integrity RTOS is important to open other applications to this processor."
» "I would like to see comprehensive support in terms of providing free software development tools, schematics, diagram, so various hardware may be made with ease."
» "I like the supervisor-mode features mixed with a decent DSP."
» "Great features. There is a lot of potential for these devices."
» "Assembly language was very easy to understand."
» "Wish they came out earlier, just designed in coldfire processor for a significant application"
» "We use TI DSP products."
» "Personally I'm much more likely to use a FPGA than a Blackfin; this is due to low volume and flexibility requirements."
» "On-chip Flash mainly goes after the microcontroller market. It also gives AD a leg up on TI. However, my non-reliance on on-chip Flash means that TI remains my DSP vendor."
» "I prefer to spend a little extra time programming an FPGA for fully parallel operation on most of my stuff.
» "Great, about time!"
» "I do not have a current need for them, but it seems like these devices provide a lot of horse power one could throw at a variety of applications. It would be fun to use them in a solution."

ARM9-based MCU line touts upgrade path from ARM7 devices
eeProductCenter's Marty Gold says: "Targeting system designers that have outgrown the ARM7 type processors, Atmel Corp. has launched its SAM9 family of 32-bit microcontrollers based on the ARM926EJ-S core. The AT91SAM9260 is the first member of the new family that shares the same integration levels and programming models as Atmel's ARM7-based MCUs, allowing direct migration between controllers based on different ARM cores."
» "10/100 MAC is the important item."
» "An interesting approach to the portability problem, but I wonder what the reality of it is. You know the saying, "if it sounds too good to be true...."
» "With built-in Ethernet module, this one is a best match for our network application."
» "Versitile core, sounds like a good configuration."
» "Excellent product. Now, if Atmel could just keep their internal drama out of the public's eye, we might be able to convince our clients to start designs with these."

8-bit MCUs pack Ethernet MAC/PHY, flash on single chip
eeProductCenter's Marty Gold says: "ASIX Electronics Corp.'s AX110xx family of 8-bit microcontrollers embed 10/100Mbps fast Ethernet MAC/PHY, the TCP/IP accelerator, and flash memory on a single chip.
The AX11001/AX11005 and AX11015 MCUs tout a single-cycle pipelined 8051/80390 core (up to 100MIPS), 128 to 512 KBytes flash memory, and 32KBytes RAM. The embedded Ethernet PHY supports Auto-MDIX, which allows either the straight-through or crossover cables to be directly connected to the device easily. The AX110xx family supports serial communication interfaces such as I&SUP2;C, SPI bus, three UART (with one supporting 921.6Kbps), and 1-wire. The parallel interfaces supported include external memory interface, local bus, and Ethernet MII. "
» "A bigger built-in FLASH and stronger built-in IP stack will make this one a perferct low-cost solution for embedded network device."
» "Convenient, with the possibility of interesting applications."
» "There are a lot of features in these devices, but do they have the processing power to support all of the features, or do you have to trade off features?"
» "Good integration of some needed features at a low price."
» "Very cost effective device."

8051-based MCU touts integrated nonvolatile ferroelectric RAM
eeProductCenter's Marty Gold says: "Ramtron International Corp. is offering what it believes is the industry's first 8051-based microcontroller with integrated nonvolatile ferroelectric random access memory (FRAM). The new VRS51L3074 is the first in a series of planned products leading to a microcontroller based entirely on FRAM, where FRAM will be used for program, data and register memory, eliminating the need for Flash and SRAM altogether, said Irv Lustigman, General Manager of Ramtron Canada. "
» "It has the specs, now it just needs to have the price ...."
» "Number of UARTS is missing. How many are there? What is "fast" write time for the FRAM?"
» "Although it is nice to have simple way as welll as unlimited times to access the FRAM, cost may be an issue.
» "Need more memory."
» "Watching this technology."
» "I like the characteristics of FRAM, especially not having to erase an entire sector before rewriting a location."
