MEC1727N-B0-I/SZ-CHR0

Application Specific Microcontrollers Overview

The MEC1727N-B0-I/SZ-CHR0 is a low-power embedded controller from the Microchip MEC172x family, designed for notebook and storage enclosure platforms. It integrates an ARM Cortex-M4F processor operating up to 48 MHz with 416KB SRAM (352KB code/64KB data) and 128 bytes of battery-backed storage. The device features a 144-pin WFBGA package and supports Intel eSPI host interfaces including Master and Slave Attached Flash Sharing. Security is provided by hardware accelerators for AES-256, RSA, and ECDSA, alongside a secure boot loader. It operates within a -40°C to +85°C temperature range on 3.3V and 1.8V supplies.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to confirm package type and feature set. Ensure compatibility with the required SPI flash configuration and check for any silicon errata sheets relevant to the manufacturing revision before integration.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring a 144-pin form factor with integrated PROCHOT monitoring. Compare against the MEC1723 variant if EEPROM support or different pin counts are required. Confirm that the 416KB SRAM allocation meets firmware size requirements and that the 1.8V eSPI interface aligns with the platform's voltage levels.

Application Specific Microcontrollers Part Context

This component belongs to the MEC172x family of mixed-signal I/O controllers. It shares the same processor core and memory architecture as other variants in the series but differs in package options and peripheral availability. The 'SZ' suffix typically denotes the 144-pin WFBGA package configuration.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing within the MEC172x family requires verifying specific pinout and feature differences.
