MEC1418-SZ

Application Specific Microcontrollers Overview

The MEC1418-SZ is a 32-bit embedded controller from the MEC140x/1x family, designed for notebook and tablet platforms. It integrates a MIPS32 M14K core operating at programmable frequencies up to 48 MHz. The device features 192 kB of code-optimized SRAM and 32 kB of data SRAM. It supports LPC, I2C, and Intel eSPI host interfaces. Key peripherals include eight 10-bit ADC channels, two 8-bit DACs, eight PWM outputs, and two PS/2 controllers. The component operates on 3.3V main power with VBAT/VTR standby planes and is housed in a 144-pin WFBGA package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'SZ' corresponds to the 144-WFBGA package configuration. Confirm that the firmware environment supports the required host interface (LPC, I2C, or eSPI) as functionality is product dependent within this family. Ensure compatibility with the target system's ACPI 3.0 compliance requirements.

Application Specific Microcontrollers Selection Notes

Select the MEC1418-SZ when 192 kB of code memory is required alongside eSPI or LPC connectivity. Compare against MEC1416-SZ if 160 kB memory suffices, or MEC1408-SZ for lower memory needs. Verify pin multiplexing constraints for GPIOs and peripheral interfaces such as SMBus and UART before finalizing the design.

Application Specific Microcontrollers Part Context

This part belongs to the MEC140x/1x series of keyboard and embedded controllers. It shares the same 144-pin WFBGA package footprint as other -SZ variants like the MEC1416-SZ and MEC1408-SZ. Differences between these parts primarily involve internal SRAM capacity and supported host interfaces.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC140x/1x family include MEC1416-SZ and MEC1408-SZ, provided memory and interface requirements are met. Cross-package replacements require schematic redesign due to pin count differences.
