STMicroelectronics ST32-M Low Power Processor Chip

STMicroelectronics introduced the ST32-M low-power processor chip. The ST32-M is ideal for managing SIM data for machine-to-machine (M2M) cellular communications. ST32-M devices will sample this quareter. Mass production in the DFN8 6 x 5mm package is expected to begin in Q1 2010. The ST32-M family complements the ST32 range (targeting classical Java SIM card ICs) and the ST33 family (for the highly secure SIM card market). The extended Flash cycling capabilities of the ST32-M family, when combined with application-specific software development, will allow Mobile Network Operators to achieve multi-million data cycles in harsh environments.

The ST32-M IC family combines the advantages of advanced non-proprietary processor architecture and high-density low-power embedded-Flash memory, enabling machines to connect to cellular networks and to authenticate themselves and communicate automatically. Applications that use M2M capabilities include the European eCall road-accident alert system that allows vehicles to automatically inform rescue services of the location and details of an accident. Other M2M applications include automatic utility-meter reading; retail systems, such as replenishment monitoring for vending machines; security equipment; and asset-management systems.

To communicate with the cellular network, the ST32-M has the same capabilities and security features as the company’s existing ST32 smart-card processor, which is used in cellphone SIM cards worldwide. The ST32-M is designed explicitly for M2M applications, with a wider temperature range (-40 degrees C to 105 degrees C) allowing M2M equipment to function in harsh environments. The chip also supports many more data-writing cycles than the standard SIM controller, enabling continuous operation over an extended lifetime. It will also store data reliably for more than 10 years.

The ST32-M uses the ARM Cortex-M3 embedded-processor core. This enables developers to benefit from the latest-generation processor technology offering high performance and low power, and to re-use existing ST32 software and design tools for faster time to market. In addition, the ST32-M family offers a very high level of flexibility and improved time-to-market to card manufacturers. The ST32-M family is available in four variants having Flash density of 256 Kbytes, 320 Kbytes, 416 Kbytes, or 512 Kbytes. The integrated memory supports total data cycling of 500,000 cycles per page or 50 million cycles per sector.
