• Description: Multimedia Applications Processors
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

Functional Description and Application Information
The ARM1136JF-S processor core features:
2.1.1
ARM1136JF-S operating frequency in C90LP process:
2.1.2
The ARM1136JF-S complex includes 16 KB Instruction and 16 KB Data L1 caches. It connects to the
i.MX31 and i.MX31L L2 unified cache through 64-bit instruction (read-only), 64-bit data read/write
(bi-directional), and 64-bit data write interfaces.
The embedded 16K SRAM can be used for audio streaming data to avoid external memory accesses for
the Low Power Audio Playback, for Security, or for other applications. There is also a 32-KB ROM for
bootstrap code and other frequently-used code and data.
A ROM patch module provides the ability to patch the internal ROM. It can also initiate an external boot
by overriding the boot reset sequence by a jump to a configurable address.
