STMicroelectronics announced the introduction of the M58BW032, a 32-Mbit Flash memory chip intended specifically for demanding automotive applications where other memory types cannot be used.
Maintaining high-speed access over a wide operating temperature range, the M58BW032 is suited for use in powertrain and transmission control modules, ABS controllers, and in other high-performance automotive systems.
Direct code execution from Flash memory is one of the main requirements of extreme temperature range applications. In this environment application code cannot be run from large DRAM memories used in more conventional systems. Instead, application designers demand a large, fast and reliable Flash memory space for code execution. Their requirement is close to the size limit of embedded Flash technology on the MCU chip, but standalone Flash devices such as the M58BW032 are well established in this area.
The new chip uses a state-of-the-art architecture to reduce access times to as low as 45ns over the full automotive temperature range (-40°C to +125°C packaged, -40°C to +150°C bare die), enabling it to be used for code execution as well as for storage.
The M58BW032 features a wide 32-bit data bus and maintains the high data throughput pioneered by the previous generation M58BW016 device. Compatibility with the M58BW016 is preserved including its lead-to-lead footprint, software configuration protocols, and power consumption performance. It matches the new generation of 75MHz 32-bit microcontrollers, which are supported by a burst reading protocol enabled by high-speed logic and the advanced 0.13µm technology.
The M58BW032 is supplied in LBGA80 and PQFP80 packages, with volume production expected in the third quarter of 2005. Pricing for the M58BW032 is US$6 per device.
