STMicroelectronics announces new 32-Mbit flash memory for automotive use
STMicroelectronics on August 30 announced a new and enhanced version of its 32-Mbit flash memory chip that is intended specifically for the automotive market. Offering high-speed memory access over a wide operating temperature range, the M58BW32F fits with automotive customers' needs for powertrain and transmission- control modules, and for other high-performance automotive systems that use the latest generation of 32-bit microcontrollers, according to the company. The new M58BW32F is manufactured with an advanced 0.11-micron technology and benefits from STMicroelectronics' experience in standalone and embedded flash memory products. Automotive-Grade certified, and qualified to the AEC- Q100 standard (revision F) as defined by the Automotive Electronics Council, the new device uses a state-of-the-art architecture to reduce access times to as low as 45ns over the full automotive temperature range (-40 degrees C to +125 degrees C for the packaged device, -40 degrees C to +150 degrees C in bare die form). Maximum burst frequency is 75MHz across the full temperature range. The M58BW32F features a wide 32-bit data bus and operates on a nominal 3.3V memory core supply. Enhanced protection techniques include flexible hardware/software protection, a secured command set for Modify operations, a Bank Erase command and a one-shot program from an internal buffer (loaded up to an 8 x Double word maximum). For security, each die embeds a unique device ID to allow the use of cryptographic algorithms to protect against illegal software modifications. The new automotive flash memory is offered in an LBGA (low-profile BGA) 80 package, which uses STMicroelectronics' ECOPACK RoHS-compliant lead-free technology, as well as in Certified Bare Die form. All devices are manufactured in STMicroelectronics' facilities qualified to ISO/TS 16949:2002, and use the company's volume-proven state-of-the-art manufacturing and testing technologies to offer reliable solutions for automotive applications. Engineering samples are available for evaluation now, with volume production planned for the third quarter of 2006. A 16-Mbit device is planned for the second half of 2006. Pricing for the M58BW32F is US$5.50 per device, according to the company.
The 32Mbit flash from STMicroelectronics will be in volume production on 0.11-micron node in 3Q 2006 |
