MEC1723N-B0-I/SZ

Application Specific Microcontrollers Overview

The MEC1723N-B0-I/SZ is an embedded controller from the MEC172x family, designed for notebook PC applications. It features an ARM Cortex-M4F processor running at up to 48 MHz and includes 416 KB of SRAM (352 KB code/64 KB data) with 128 bytes of battery-backed storage. The device operates within a temperature range of -40°C to +85°C and supports 3.3 V and 1.8 V power rails. Key interfaces include Intel eSPI compliant host communication, multiple SPI controllers, I2C/SMBus, UARTs, and GPIOs. Security features encompass hardware accelerators for AES-256, RSA, and ECDSA, alongside a secure boot loader.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F core with 416 KB SRAM and 128-byte battery-backed storage
• Intel eSPI host interface supporting Master and Slave Attached Flash Sharing
• Hardware security accelerators for AES, RSA, ECDSA, and SHA algorithms
• Integrated thermal management including PROCHOT monitoring and Power Guard technology

Application Specific Microcontrollers Applications

• Notebook PC embedded controllers
• Storage enclosure platforms
• Low-power PC architecture designs requiring ACPI S0-S5 support

Application Specific Microcontrollers Procurement Notes

Verify package compatibility as this model uses a 144-pin WFBGA, distinct from the 176-pin variants in the same family. Confirm firmware requirements for the Secure Boot Loader and ensure the target system provides the necessary VBAT, VTR, and VCC power planes for proper operation.

Application Specific Microcontrollers Selection Notes

Select this part over other MEC172x variants based on the specific 144-pin package requirement. Note that unlike the MEC1727N or MEC1723N-LJ versions, this device does not include internal EEPROM or internal SPI flash memory. Ensure the application utilizes the PROCHOT monitor input only, as bidirectional IO is not supported in this package.

Application Specific Microcontrollers Part Context

This component belongs to the MEC172x family of low-power mixed-signal I/O controllers. It shares the same processor core and memory architecture with the MEC1727N-B0-I/SZ but differs in peripheral availability such as EEPROM and internal flash. It is functionally similar to the MEC1723N-B0-I/LJ but utilizes a smaller 144-pin footprint instead of the 176-pin WFBGA.

Application Specific Microcontrollers Replacement Considerations

Direct pin-compatible replacements within the MEC172x family are limited by package differences. The MEC1727N-B0-I/SZ is the closest sibling in the 144-pin WFBGA package, though it lacks internal EEPROM support found in some other variants.
