The SBC1651 is ideal for high-performance, low-power embedded applications.  Freescale’s i.MX515 ARM Cortex-A8 CPU operates at 800MHz delivering the performance needed to run multimedia-rich applications in embedded environments.  Offering several embedded I/O features, the SBC1651 also consumes minimal power, satisfying the demanding environmental conditions in which OEMs must operate. 

A high degree of integration allows a variety of I/O functions to be included on the SBC1651.  On-board peripherals include dual Ethernet, USB On-The-Go, a real-time clock, watchdog timer, audio support, TV out, 24-bit LVDS flat panel display output, 4-wire touchscreen interface, two PWM outputs, a SATA HDD port, two SD/MMC card slots, 1-Wire interface, seven serial ports, and 24 lines of discrete I/O.  For additional expansion, the StackableUSB interface allows for rugged, reliable board-to-board communication via USB, I2C, and SPI.

All these features make the SBC1651 ideal for handheld, mobile devices or remote applications requiring rich connectivity and low power.

TECHNICAL DETAILS:

At the heart of the SBC1651 is the Freescale i.MX515 multimedia applications processor, a System on Chip (SOC) offering high- performance processing optimized for the lowest power consumption. The core of i.MX515 is an 800MHz ARM Cortex-A8 CPU. The CPU is augmented by a floating-point coprocessor, ARM’s NEON SIMD media accelerator, and OpenGL ES 2.0 and OpenVG 1.1 hardware accelerators for fast, power-efficient graphics operations.

The i.MX515 SOC integrates many peripherals, including an interrupt controller, watchdog timer, SDRAM and flash memory controllers, three High-Speed USB ports, one Full-Speed On-The-Go USB port, a 10/100 Ethernet MAC, three 16C550 UARTs, 1-Wire interface, 24-bit flat panel display output, 4-wire touchscreen interface, an audio port, and PWM and TV outputs.

In addition to the peripherals built into the i.MX515, the SBC1651 packs on a second 10/100 Ethernet port, four more 16C550 UARTs, a Controller Area Network (CAN) controller, and 24 bits of 82C55A-compatible programmable parallel I/O.

The SBC1651 offers three boot options: A dedicated 4MB SPI NOR flash memory, a partition of the NAND flash, and a bootable SD/MMC card slot.

The SBC1651 memory subsystem provides 512MB of DDR2 SDRAM for application data. The 4MB SPI NOR flash memory holds the bootloader and operating system. Up to 2GB NAND flash is also available for operating system and non-volatile user storage.

If a larger program or data storage space is required, or if portability is needed, there are two options for expansion. Plug in an SD card to the second SD/MMC card slot, or use the SATA HDD connector to attach an external hard drive.

Seven (7) 16C550-compatible RS232 serial ports allow communication with low-speed devices. COM7 is software-configurable for half-duplex RS485 communication.

The SBC1651 can be powered from an external 5 VDC source or a battery. If external power is supplied while a battery is plugged in, the battery will be recharged. Advanced power management is enabled by the new Freescale MC13892.

The SBC1651 becomes a powerful front-end processor for control applications with the standard StackableUSB expansion. This popular I/O channel accommodates multiple I/O boards on the top side and/or the bottom side of the board without use of a hub.

For true 32-bit application development, the SBC1651 supports 32-bit operating systems such as Linux, Windows CE, VxWorks, and Android. All have full tool suites available, including compilers and debuggers. 

For pre-configured sets of options, Micro/sys can provide OEMs with a single part number for ordering.  In addition, custom versions of the SBC1651 are available.  Please call Micro/sys Technical Sales for details.
