Description
General part information
MEC1521 Series
The MEC152x is a family of low power integrated embedded controllers designed for notebook applications. The MEC152x is a highly-configurable, mixed-signal, advanced I/O controller architecture. It contains a 32-bit ARM® CortexM4 processor core with closely-coupled memory for optimal code execution and data access. An internal ROM, embedded in the design, is used to store the power on/boot sequence and APIs available during run time. When VTR\_CORE is applied to the device, the secure boot loader API is used to download the custom firmware image from the system’s shared SPI Flash device, thereby allowing system designers to customize the device’s behavior.
The MEC152x device is directly powered by a minimum of two separate suspend supply planes (VBAT and VTR) and senses a third runtime power plane (VCC) to provide "instant on" and system power management functions. The MEC152x has two banks of I/O pins that are able to operate at either 3.3 V or 1.8 V. Operating at 1.8V allows the MEC152x to interface with the latest platform controller hubs and will lower the overall power consumed by the device, whereas 3.3V allows this device to be integrated into legacy platforms that require 3.3V operation.
The MEC152x host interface is the Intel® Enhanced Serial Peripheral Interface (eSPI). The eSPI Interface is a 1.8V interface that operates in single, double and quad I/O modes. The eSPI Interface supports all four eSPI channels: Peripheral Channel, Virtual Wires Channel, OOB Message Channel, and Run-time Flash Access Channel. The eSPI hardware Flash Access Channel is used by the Boot ROM to support Master Attached Flash Sharing (MAFS). In addition, the MEC152x has specially designed hardware to support Slave Attached Flash Sharing (SAFS). The eSPI SAFS Bridge imposes Region-Based Protection and Locking security feature, which limits access to certain regions of the flash to specific masters. There may be one or more masters (e.g., BIOS, ME, etc) that will access the SAF via the eSPI interface. The ARM® Cortex-M4 processor is also considered a master, which will also have its access limited to EC only regions of SPI Flash as determined by the customer firmware application.
