The BCM1122A4KEB is a single-core MIPS64-based System-on-Chip (SoC) from Broadcom Limited, operating at 400 MHz. It delivers 2.2 DMIPS/MHz performance with a typical power dissipation of 4 W. The memory subsystem includes 32 KB instruction and 32 KB data L1 caches, plus a 128 KB shared L2 cache with ECC protection. The on-chip bus provides 51 Gbps bandwidth, and the memory controller supports 13 Gbps over a 64-bit DDR interface with ECC.
Integrated peripherals include two Ethernet MACs (one 10/100/1000 and one 10/100), a 32-bit PCI 2.2 interface, SMBus, PCMCIA, and dual serial ports. The SoC is software-compatible with the BCM1250 and BCM1125H and supports operating systems such as VxWorks, Linux, NetBSD, QNX, and OSE.
Typical applications include networking equipment (routers and switches), control plane processing, line cards, and broadband access devices. The part is classified as a uniprocessor SoC, suitable for embedded systems requiring high integration and low power.
