TIBBO TECHNOLOGY’S PLUS1 SP7021 SOC WITH LINUX-CAPABLE PROCESSING

Generally, the SoCs have complex integration processes for deployment purposes. Even if the integration is simple then there is a compromise with the performance factor of the device. Tibbo Technology’s Plus1 SP7021 SoC ensures simple integration with efficient performance comparable with Linux-capable processing. Also, the I/O ports for easy interfacing make it a good fit for IoT applications.

Plus1 SP7021 SoC comes with multi-core processors and up to 512MB of DDR3 memory with I/O ports in a single LQFP package. Also, the core includes quad-core ARM Cortex-A7 working up to 960MHz with NEON multimedia processing engine for multimedia applications. It comes with an ARM926 real-time core with an operating frequency of 202 MHz. It also features a low-power 8051 with selectable operating speeds.

GPIO ports include nine 8-bit ports (P0-8) out of which P1-8 are 5V-tolerant. All the GPIO lines of Plus1 SP7021 SoC have 3.3V logic levels along with 16mA source/sink current for all lines of port 0. It features 8 separate interrupt lines that can be configured as wake-up lines of the chip. Also, each GPIO line can be individually tri-stated to work as an input or enabled to work as outputs. There are two ways of controlling GPIO lines through the 8-bit registers or by using the bitwise access to individual lines.
