STMicroelectronics Introduces ST SPEAr1310 Dual Cortex Microcontroller



STMicroelectronics has introduced the ST SPEAr1310  microcontroller, a dual-core microcontroller with a DDR3 memory interface and plenty of networking peripherals.

The 32-bit ST SPEAr1310 microcontroller has two ARM Cortex-A9 cores (ARM926EJ-S) and a DDR3 (Third-generation double-data rate) memory interface. It is manufactured in STMicroelectronics' 55nm HCMOS process technology.

The ST SPEAr1310 microcontroller incorporates the ST Network-on-Chip (STNoC) technology, which internally networks the microcontroller's on-chip peripheral & IP blocks in a "spidergon" arrangement, where each on-chip peripheral & IP block is connected to adjacent blocks, rather than the traditional common bus arrangement. This results in a more efficient architecture.

On-chip configurable logic is also available, for up to 1300 Kgates.

The ST SPEAr1310 microcontroller with dual ARM Cortex-A9 processors support both fully symmetric and asymmetric operations, at speeds of 600MHz/core (industrial worst-case conditions) for 3000 DMIPS equivalent.

"ST SPEAr1310 is the first device in the recently announced SPEAr1300 family and others will follow shortly," said Loris Valenti, General Manager of STMicroelectronics' Computer Systems Division. "With its innovative architecture and powerful feature set, SPEAr1310 is at the leading edge of the embedded processor market and enables an unprecedented mix of cost competitiveness, performance and flexibility."
