GENEVA -- STMicroelectronics today announced an expansion of its memory offering for automotive applications, including four new 16-megabit flash chips configured with 32-bit wide data buses and a 128-kilobit (by-16-bit) SRAM dedicated for automotive system designs.
The flash memories sport zero-wait-states and burst-mode features as well as 56-MHz frequencies, said STMicroelectronics. The M58BW016xx flash chips have an advanced 32-bit data bus architecture and operate over a wide temperature range for automotive applications in engine control, telematics computing in vehicles, and navigation systems, according to the European chip maker.
The flash devices contain a boot-block architecture comprising eight parameter blocks of 64 Kbits each and 31 main blocks of 512 Kbits each.
The 128-Kbit SRAM, designated M616Z08, is based on a high-performance, six-transistor memory cell. The static RAM operated on voltages of 3.6 to 2.34 volts. The SRAM has an access time as fast as 20 ns and offers separate Write Enable pins for byte control. It is fabricated with 0.35-micron CMOS and has an operating temperature range of -40 degrees to +125 degrees C. It is packaged in a 44-pin SOIC. Prices start at $9 each in quantities of 1,000.
