![]() IFC has two register pages.Till IFC version 1.4 each register page is 4KB each.But IFC ver 2.0 register page size is 64KB each.IFC regiters structure is break into two viz FCM and RUNTIME.FCM(Flash control machine) registers are defined in PAGE0 and controls IFC generic functionality. RUNTIME registers are defined in PAGE1 and controls NAND and GPCM funcinality. FCM and RUNTIME structures defination is common for IFC version 1.4 and 2.0.

Overview -------- The BSC9132 is a highly integrated device that targets the evolving Microcell, Picocell, and Enterprise-Femto base station market subsegments. The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850 core technologies with MAPLE-B2P baseband acceleration processing elements to address the need for a high performance, low cost, integrated solution that handles all required processing layers without the need for an external device except for an RF transceiver or, in a Micro base station configuration, a host device that handles the L3/L4 and handover between sectors. The BSC9132 SoC includes the following function and features: - Power Architecture subsystem including two e500 processors with 512-Kbyte shared L2 cache - Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2 cache - 32 Kbyte of shared M3 memory - The Multi Accelerator Platform Engine for Pico BaseStation Baseband Processing (MAPLE-B2P) - Two DDR3/3L memory interfaces with 32-bit data width (40 bits including ECC), up to 1333 MHz data rate - Dedicated security engine featuring trusted boot - Two DMA controllers - OCNDMA with four bidirectional channels - SysDMA with sixteen bidirectional channels - Interfaces - Four-lane SerDes PHY - PCI Express controller complies with the PEX Specification-Rev 2.0 - Two Common Public Radio Interface (CPRI) controller lanes - High-speed USB 2.0 host and device controller with ULPI interface - Enhanced secure digital (SD/MMC) host controller (eSDHC) - Antenna interface controller (AIC), supporting four industry standard JESD207/four custom ADI RF interfaces - ADI lanes support both full duplex FDD support & half duplex TDD - Universal Subscriber Identity Module (USIM) interface that facilitates communication to SIM cards or Eurochip pre-paid phone cards - Two DUART, two eSPI, and two I2C controllers - Integrated Flash memory controller (IFC) - GPIO - Sixteen 32-bit timers The SC3850 core subsystem consists of the following: - 32 KB, 8-way, level 1 instruction cache (L1 ICache) - 32 KB, 8-way, level 1 data cache (L1 DCache) - 512 KB, 8-way, level 2 unified instruction/data cache (L2 cache/M2 memory) - Memory management unit (MMU) - Global interrupt controller ( GIC) - Debug and profiling unit (DPU) - Two 32-bit quad timers BSC9132QDS board Overview ------------------------- 2Gbyte DDR3 (on board DDR), Dual Ranki 32Mbyte 16bit NOR flash 128Mbyte 2K page size NAND Flash 256 Kbit M24256 I2C EEPROM 128 Mbit SPI Flash memory SD slot USB-ULPI eTSEC1: Connected to SGMII PHY eTSEC2: Connected to SGMII PHY PCIe CPRI SerDes I2C RTC DUART interface: supports one UARTs up to 115200 bps for console display Frequency Combinations Supported -------------------------------- Core MHz/CCB MHz/DDR(MT/s) 1.
