MEC1428 is the latest member of the MEC14XX family and adds a new level of design functionality for computing engineers by adding Slave Attached Flash (SAF), which is an optimal solution for USB Type-C™ power delivery. This device is pin and register compatible with the MEC140X and MEC141X families, which allows designers to easily add eSPI and additional features and have more flexibility in their designs. It retains eSPI Master Attached Flash (MAF) capability.
The MEC14xx family is a keyboard and embedded controller
customized for notebooks and computing platforms. The MEC140X/1X/2X family is a
highly-configurable, mixed signal, advanced I/O controller architecture.
MEC1428 incorporates a 32-bit MIPS32 M14K Microcontroller core with 192 KB of
closely-coupled SRAM for code and data that loads from SPI Flash. Designers can
leverage the host SPI-flash (used for BIOS storage) for non-volatile EC
firmware storage, as a cost-effective system solution.
Microchip’s MEC14XX family also provides a flexible arrangement that allows
multiple I/O signals to be configured to support either 3.3V or 1.8V, reducing
the system bill-of-materials cost by eliminating the need for external voltage
translators. The MEC1428 communicates with the system host through the Intel
Enhanced Serial Peripheral Interface (eSPI) or through Intel's Low Pin Count
(LPC).
All members of the MEC14XX family are pin and register compatible and are
supported by Microchip’s development tools. Examples include the MPLAB® XC
Compilers, the MPLAB REAL ICE™ In-Circuit Emulator (part #
DV244005), the MPLAB ICD 3 In-Circuit Debugger (part # DV164035) and the PICkit™ 3
Starter Kit (part # DV164130).

 MPLAB® X Integrated Development Environment (IDE) is an expandable, highly configurable software program that incorporates powerful tools to help you discover, configure, develop, debug and qualify embedded designs for most of Microchip’s microcontrollers, microprocessors and digital signal controllers.
|
| When combined with our free and award-winning MPLAB X Integrated Development Environment (IDE), the fully graphical frontend provides:
Editing errors and breakpoints that match corresponding lines in the source code
Single stepping through C and C++ (C++ only available in MPLAB XC32++ compilers) source code to inspect variables and structures at critical points
Data structures with defined data types, including floating point, display in watch windows

| The MPLAB® PICkit™ 5 in-circuit debugger/programmer enables quick prototyping and portable, production-ready programming for all Microchip devices, including PIC® microcontrollers (MCUs) and dsPIC® Digital Signal Controllers (DSCs), AVR® and SAM devices and Arm® Cortex®-based microprocessors (MPUs).
|
| The MPLAB® ICD 5 In-Circuit Debugger/Programmer offers advanced connectivity and power options for developers of designs based on PIC®, AVR® and SAM devices and dsPIC® Digital Signal Controllers (DSCs).
|
| The MPLAB ICE 4 in-circuit emulator system boosts productivity with feature-rich programming and debugging for PIC®, AVR® and SAM devices and dsPIC® Digital Signal Controllers (DSCs).
|
| The MPLAB® Snap In-Circuit Debugger/Programmer allows affordable, fast and easy debugging and programming of PIC®, dsPIC® and AVR flash MCUs and MPUs, using the powerful graphical user interface of MPLAB X Integrated Development Environment (IDE). The MPLAB Snap can be connected to a design engineer's computer using a High-Speed USB 2.0 interface and can be connected to the target via an 8-pin Single In-Line (SIL) connector. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™ (ICSP™). It has all the speed and features entry-level users need to quickly debug their prototype.
