MEC1727N-B0-I/SZ

Application Specific Microcontrollers Overview

The MEC1727N-B0-I/SZ is a low-power embedded controller from the MEC172x family, designed for notebook and storage enclosure platforms. It features an ARM Cortex-M4F processor running at up to 48 MHz with 416 KB of SRAM (352 KB code, 64 KB data) and 128 bytes of battery-backed storage. The device integrates a secure bootloader with hardware accelerators for AES-256, RSA, and ECDSA. Key interfaces include Intel eSPI compliant host communication, SPI Master/Slave controllers, I2C/SMBus, UARTs, and GPIOs. Operating voltages are 3.3 V and 1.8 V, with a temperature range of -40°C to +85°C in a 144-pin WFBGA package.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to confirm package type and temperature grade. Ensure compatibility with existing firmware images regarding the secure boot loader requirements and cryptographic key storage configurations.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring the 144-pin WFBGA package form factor. Confirm that the system design supports the required 3.3 V and 1.8 V power planes. Verify that the internal 512 KByte SPI Flash memory requirement is met by external components if not integrated in this specific variant.

Application Specific Microcontrollers Part Context

This component belongs to the MEC172x family of mixed-signal advanced I/O controllers. It shares the same processor core and memory architecture as other variants like the MEC1723N but differs in package options and specific peripheral integration such as EEPROM support.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC172x family include the MEC1723N-B0-I/SZ. Verify pinout compatibility and feature set differences, particularly regarding EEPROM presence and internal SPI flash availability, before substitution.
