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.

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.
