MEC1416-I/NU

Application Specific Microcontrollers Overview

The MEC1416-I/NU 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 up to 48 MHz with 160 kB of code-optimized SRAM and 32 kB of data SRAM. The device supports LPC, I2C, and eSPI host interfaces. Key peripherals include eight 10-bit ADCs, two 8-bit DACs, three SMBus controllers, two PS/2 ports, and eight PWM outputs. It operates on 3.3 V power supplies and features low standby current capabilities.

Application Specific Microcontrollers Feature Summary

• Integrated 160 kB Code SRAM and 32 kB Data SRAM
• Support for LPC, I2C, and Intel eSPI host interfaces
• Eight 10-bit ADC channels and two 8-bit DAC channels

Application Specific Microcontrollers Applications

• Notebook PC keyboard and embedded controllers
• Tablet platform system management
• Connected Standby systems requiring low-power states

Application Specific Microcontrollers Procurement Notes

Verify that the specific part number matches the required memory configuration (160 kB SRAM) and interface support (LPC/eSPI/I2C). Confirm the package type corresponds to the VTQFP-128 variant. Ensure the temperature grade aligns with the industrial specifications if applicable.

Application Specific Microcontrollers Selection Notes

Select this component when a split-architecture EC design is needed with high-performance processing. The 160 kB SRAM capacity supports complex firmware requirements. Verify compatibility with the target platform's power planes (VBAT/VTR) and interface protocols before integration.

Application Specific Microcontrollers Part Context

This model belongs to the MEC140x/1x series of advanced I/O controllers. It shares the same package and core architecture as variants like the MEC1414 and MEC1418, differing primarily in internal SRAM size and supported host interfaces.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC140x/1x family include the MEC1414-NU and MEC1418-NU. These parts share the same VTQFP-128 package and core but offer different SRAM capacities (128 kB and 192 kB respectively).
