NXP Semiconductors’ i.MX 7 family of processors offers high-performance processing in applications requiring low power consumption, while providing a wide range of connectivity options. This means that they are ideal for use in the latest generation of smart handheld payment terminals.
The i.MX 7 family consists of two series of devices: the i.MX 7Solo series features an advanced implementation of a single ARM® Cortex®-A7 processor core, which operates at 800MHz, alongside an ARM Cortex-M4 co-processor.
The i.MX 7Dual has two ARM Cortex-A7 cores operating at up to 1GHz, as well as a single ARM Cortex-M4 core.
The i.MX 7 family supports multiple memory types including:
• DDR3, low-power DDR2 and low-power DDR3 DRAM
• Quad SPI Flash memory
• NAND Flash
• Embedded Multi Media Card (eMMC) Flash
• NOR Flash
Among the high-speed connectivity interfaces is support for Gigabit Ethernet with Audio-Video Bridging (AVB) capability, which is used in applications requiring real-time and deterministic responses.
Crucially for payment terminals, the i.MX 7 processors provide a complete security infrastructure, including support for secure boot, hardware acceleration for encryption, internal and external tamper detection, secure RAM, resistance to Differential Power Analysis (DPA) and a secure JTAG interface.
• 96kbytes of ROM
• 256kbytes of SRAM
• 512kbytes of L2 cache memory
• Parallel RGB and MIPI DSI display interfaces
• Parallel and MIPI CSI camera interfaces
