MEC1723N-B0-I/LJ

Application Specific Microcontrollers Overview

The MEC1723N-B0-I/LJ is an embedded controller from the MEC172x family, designed for notebook PC keyboard and embedded control applications. It integrates an ARM Cortex-M4F processor operating up to 48 MHz with a single 4GB addressing space. The device features 416KB of code/data SRAM (352KB optimized for code, 64KB for data) and 128 bytes of battery-powered storage. It supports 1.71V to 3.465V supply voltages and operates within a temperature range of -40°C to 85°C. Key interfaces include eSPI, SPI, I2C, LPC, and UART, housed in a 176-WFBGA package.

• Storage enclosure platforms

Application Specific Microcontrollers Procurement Notes

Verify the specific package variant against the datasheet Table 1-1, as the MEC172x family includes both 144-pin and 176-pin options. Confirm that the required internal memory configurations, such as the presence of internal SPI flash or EEPROM, match the specific sub-model requirements for the target design.

Application Specific Microcontrollers Selection Notes

Select this component when an Intel eSPI interface is required for modern platform controller hubs. Ensure the design utilizes the 176-pin WFBGA package if higher pin counts are needed compared to the 144-pin alternative. Verify power domain requirements, as the device requires separate suspend supplies (VBAT and VTR) and a runtime plane (VCC).

Application Specific Microcontrollers Part Context

This part belongs to the MEC172x series of low-power integrated embedded controllers. The MEC1723N-B0-I/LJ specifically denotes the 176-pin WFBGA package variant within this family, sharing core architectural features with other members like the MEC1721N and MEC1727N while differing in peripheral availability and package size.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC172x family include MEC1721N-B0-I/LJ and MEC1727N-B0-I/LJ. These share the same 176-pin package and core processor but may differ in specific peripheral implementations such as internal SPI flash or EEPROM support.
