MEC1727N-B0-I/LJ

Application Specific Microcontrollers Overview

The MEC1727N-B0-I/LJ 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 with a single 4GB addressing space. The device includes 416KB of SRAM (352KB code/64KB data), 128 bytes of battery-backed storage, and 4Kbits of OTP. Security is provided by hardware accelerators for AES-256, RSA, ECDSA, and SHA algorithms, alongside a True Random Number Generator. It supports eSPI host interface compliant with Intel specifications, offering Master and Slave Attached Flash Sharing capabilities.

Application Specific Microcontrollers Feature Summary

• Systems requiring ACPI power state management (S0-S5)

Application Specific Microcontrollers Procurement Notes

Verify package type and internal memory options against specific datasheet tables. Confirm ordering suffixes match required pin counts and flash configurations. Check for latest errata sheets regarding silicon revisions. Ensure compatibility with platform voltage requirements (1.8V/3.3V).

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring integrated Slave Attached Flash Sharing (SAFS) and Prochot monitoring. Compare with MEC1723 variants if EEPROM support or different package sizes are needed. Verify that the 176-pin WFBGA package fits the board layout constraints.

Application Specific Microcontrollers Part Context

Part of the MEC172x family of low-power mixed-signal I/O controllers. Shares the same core processor and general peripheral set as other MEC172x members but differs in specific memory configurations and package options like the 176-pin WFBGA.

Application Specific Microcontrollers Replacement Considerations

MEC1723N-B0-I/LJ offers similar functionality but lacks internal SPI flash and includes EEPROM support. MEC1727N-B0-I/SZ provides the same features in a 144-pin package.
