MEC1705Q-C2-I/SZ

Application Specific Microcontrollers Overview

The MEC1705Q-C2-I/SZ is an embedded controller within the MEC170x family, designed for notebook and tablet platforms. It integrates a 32-bit ARM Cortex-M4 processor core with hardware floating-point support. The device features up to 480KB of total SRAM, including battery-backed memory, and includes cryptographic engines for AES, SHA, and public key algorithms. It supports LPC and eSPI host interfaces, providing extensive I/O capabilities such as GPIOs, PS/2 ports, UARTs, and SMBus controllers.

Application Specific Microcontrollers Feature Summary

• ARM Cortex-M4F core with hardware FPU and secure boot capabilities
• Integrated cryptographic engine supporting AES, SHA, RSA, and ECC
• Supports both LPC and eSPI host communication interfaces
• Up to 480KB internal SRAM with battery-backed options

Application Specific Microcontrollers Applications

• Notebook PC embedded controllers
• Tablet platform I/O management
• Systems requiring secure firmware execution via SPI Flash

Application Specific Microcontrollers Procurement Notes

Verify the specific package variant (144-pin WFBGA) and temperature grade (Industrial -40°C to +85°C) against system requirements. Confirm that the 480KB SRAM configuration matches the design's memory allocation needs. Ensure compatibility with the target host interface (LPC or eSPI) during integration.

Application Specific Microcontrollers Selection Notes

Select this model when both LPC and eSPI host interfaces are required alongside high-security features. The MEC1705 provides 123 GPIOs and 480KB SRAM, distinguishing it from lower-capacity variants like the MEC1701. Verify that the 144-pin WFBGA package fits the PCB layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the MEC170x series of keyboard and embedded controllers. It shares the same core architecture and security features as other members but offers specific pin counts and memory configurations tailored for mid-to-high-end mobile computing devices.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the MEC170x family include the MEC1701Q-C2-SZ, though it offers fewer GPIOs and potentially different SRAM configurations. Cross-family migration requires re-evaluation of pinout compatibility and firmware adaptation.
