ST Life.augmented


Dual-core Cortex A9 embedded MPU for communications
  • Obsolete

The SPEAr1310 is a member of the SPEAr family of embedded MPUs for network devices.

It offers an unprecedented combination of processing performance and aggressive power reduction control for next-generation communication appliances.

The SPEAr1310 is based on ARM's new multi-core technology (Cortex-A9 SMP/AMP) and it is manufactured with ST's 55nm HCMOS low power silicon process.

SPEAr1310 targets cost and power sensitive networking applications for the home and small business as well as telecom infrastructure equipment, with lowest overall leakage under real operating conditions. The device integrates ARM's latest generation ARMv7 CPU cores, ST's proven C3 security coprocessor, and advanced connectivity interfaces and controllers.
