• Six StarCore SC3850 DSP subsystems, each with an SC3850
DSP core, 32 Kbyte L1 instruction cache, 32 Kbyte L1 data cache,
unified 512 Kbyte L2 cache configurable as M2 memory in
64 Kbyte increments, memory management unit (MMU),
extended programmable interrupt controller (EPIC), two
general-purpose 32-bit timers, debug and profiling support,
low-power Wait, Stop, and power-down processing modes, and
ECC/EDC support.
• Chip-level arbitration and switching system (CLASS) that
provides full fabric non-blocking arbitration between the cores
and other initiators and the M2 memory, shared M3 memory,
DDR SRAM controllers, device configuration control and status
registers, MAPLE-B, and other targets.
• 1056 Kbyte 128-bit wide M3 memory, 1024 Kbytes of which can
be turned off to save power.
• 96 Kbyte boot ROM.
• Three input clocks (one global and two differential).
• Five PLLs (three global and two Serial RapidIO PLLs).
• Multi-Accelerator Platform Engine for Baseband (MAPLE-B)
with a programmable system interface, Turbo decoding, Viterbi
decoding, and FFT/iFFT and DFT/iDFT processing. MAPLE-B
can be disabled when not required to reduce overall power
consumption.
• Two DDR controllers with up to a 400 MHz clock (800 MHz data
rate), 64/32 bit data bus, supporting up to a total 2 Gbyte in up to
four banks (two per controller) and support for DDR2 and DDR3.
• DMA controller with 32 unidirectional channels supporting 16
memory-to-memory channels with up to 1024 buffer descriptors
per channel, and programmable priority, buffer, and multiplexing
configuration. It is optimized for DDR SDRAM.
• Up to four independent TDM modules with programmable word
size (2, 4, 8, or 16-bit), hardware-base A-law/μ-law conversion,
up to 62.5 Mbps data rate for each TDM link, and with glueless
interface to E1 or T1 framers that can interface with
H-MVIP/H.110 devices, TSI, and codecs such as AC-97.
• High-speed serial interface that supports two Serial RapidIO
interfaces, one PCI Express interface, and two SGMII interfaces
(multiplexed). The Serial RapidIO interfaces support 1x/4x
operation up to 3.125 Gbaud with a single messaging unit and two
DMA units. The PCI Express controller supports 32- and 64-bit
addressing, x4, x2, and x1 link.
• QUICC Engine technology subsystem with dual RISC
processors, 48 Kbyte multi-master RAM, 48 Kbyte instruction
RAM, supporting two communication controllers for two Gigabit
Ethernet interfaces (RGMII or SGMII), to offload scheduling
tasks from the DSP cores, and an SPI.
• I/O Interrupt Concentrator consolidates all chip maskable
interrupt and non-maskable interrupt sources and routes then to
INT_OUT, NMI_OUT, and the cores.
• UART that permits full-duplex operation with a bit rate of up to
6.25 Mbps.
• Two general-purpose 32-bit timers for RTOS support per SC3850
core, four timer modules with four 16-bit fully programmable
timers, and eight software watchdog timers (SWT).

Signal List By Ball Location
Table 1
presents the signal list sorted by ball number. When designing a board, make sure that the power rail for each signal is
appropriately considered. The specified power rail must be tied to the voltage level specified in this document if any of the
related signal functions are used (active)
Note:
The information in
Table 1
and
Table 2
distinguishes among three concepts. First, the power pins are the balls of the
device package used to supply specific power levels for different device subsystems (as opposed to signals). Second,
the power rails are the electrical lines on the board that transfer power from the voltage regulators to the device. They
are indicated here as the reference power rails for signal lines; therefore, the actual power inputs are listed as N/A
with regard to the power rails. Third, symbols used in these tables are the names for the voltage levels (absolute,
recommended, and so on) and not the power supplies themselves.
