STMicroelectronics' newest 32Mbit flash memory chip offers high-speed memory access over a wide operating temperature range.

Designed to specifically address the needs for powertrain and transmission-control modules in automotive applications, 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 flash memory is said to be a perfect fit for automotive systems that use the latest generation of 32bit microcontrollers. The device is manufactured in ST's 0.11-micron technology.

Automotive grade
Automotive-grade certified, and qualified to the AEC-Q100 standard (revision F) as defined by the Automotive Electronics Council, the M58BW32F uses an architecture to reduce access times to as low as 45ns over the full automotive temperature range (-40C to 125C for the packaged device, -40C to 150C in bare die form). Maximum burst frequency is 75MHz across the full temperature range.

The new automotive flash memory is offered in an LBGA80 package, which uses ST's ECOPACK RoHS-compliant lead-free technology, as well as in Certified Bare Die form.

Engineering samples are already available for evaluation, with volume production planned for Q3 2006. A 16Mbit device is planned for the second half of 2006. Pricing for the M58BW32F is $5.50 per device.
