According to a new teardown posted by Chipworks, the M7 sensor-oriented coprocessor that Apple8217;s talked up as an always-on enhancement for the iPhone 5S is, in fact, a Cortex-M3 core built by NXP, the NXP LPC18A1. This part doesn8217;t have an exact public SKU, but looking at NXP8217;s product line, we can get a feel for what the chip8217;s specs are ly to be. The chip has a three-stage pipeline, ly runs at 180MHz (though lower clock speeds are possible), can contain up to 1MB of N memory. The chip also has 136KB of on-board SRAM for program storage.
