BCM1122A4KEBG Description

Short technical summary and product information.

The BCM1122A4KEBG is a MIPS64-based uniprocessor system-on-chip designed by Broadcom Limited for networking and control plane applications. It features a 400 MHz CPU core with a quad-issue in-order pipeline, 32 KB L1 instruction cache, 32 KB L1 data cache, and a 128 KB L2 cache shared by the CPU and I/O bridges with ECC protection.

The SoC includes a DDR memory controller supporting DDR SDRAM, SGRAM, and FCRAM with a 64-bit data bus plus ECC, operating at 100 MHz clock and 200 Mbps data rate. For connectivity, it provides one 10/100/1000 Ethernet MAC and one 10/100 Ethernet MAC, both 802.3 compliant, plus a 32-bit PCI 2.2 interface configurable as host bridge or target device.

The device is housed in a BGA package for surface mount assembly using solder ball termination. Typical power dissipation is 4 watts at 400 MHz. The BCM1122 is software-compatible with the BCM1250 and BCM1125H processors.
