GenevaSTMicroelectronics has added four new devices to its SPEAr microprocessor family, targeting embedded-control applications across market segments from computer peripherals and communication to industrial automation.
ST's SPEAr microprocessors are based on the latest ARM core technology, and manufactured in low-power 90nm and 65nm HCMOS (high-speed CMOS) process technologies. The devices combine one or two advanced ARM9 processor cores (ARM926EJ-S up to 400MHz in typical conditions, or 333MHz in worst-case conditions of temperature and voltage) with memory interfaces, and a large set of IP blocks delivering connectivity, communication, and audio/video functions for different applications.
The SPEAr microprocessors target networked devices used for communication, display and control in applications including VoIP phones, wireless access devices, printers, thin-client computers, PC docking stations, bar-code scanners/readers, home appliances, residential control and security systems, and medical lab/diagnostics equipment.
The SPEAr family members include the SPEAr300 for human-machine interface and security applications. It contains a camera interface; LCD and keyboard controller; crypto accelerator; TDM bus; USB 2.0; and Fast Ethernet.
The SPEAr310 is tailored for telecom network applications. Integrated IP blocks include five fast Ethernet ports; TDM bus; two HDLC ports; crypto accelerator; and USB 2.0.
The SPEAr320 is suitable for factory automation and consumer applications. Its function blocks include two CAN interfaces; four serial ports; standard parallel port; LCD controller; crypto accelerator; and USB 2.0.
The dual-core SPEAr600, with benchmarked performance of 733 DMIPS (Dhrystone million instructions per second), targets highly compute-intensive embedded applications across market segments. In addition to the two cores, it contains Giga Ethernet; USB 2.0; external local bus access for glueless FPGA connection; and an LCD controller.
Pricing: In mass production quantities, the single-core models (SPEAr300/310/320) cost $7 and the dual-core SPEAr600 sells below $9.
Availability: Full production.
