MEC1633X-AUE

Application Specific Microcontrollers Overview

The MEC1633X-AUE is a low-power 32-bit mobile embedded controller manufactured by Microchip Technology. It features an ARC-625D core operating at up to 20.27 MHz with 192 KB of embedded flash and 16 KB of dual-ported SRAM. The device operates on a single 3.3V supply and supports LPC bus frequencies from 19.2MHz to 33MHz. It includes 135 general-purpose I/O pins, four SMBus controllers, PECI 3.0, and multiple timer interfaces. The component is housed in a 169-pin LFBGA package and functions within a temperature range of 0°C to +85°C.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System. The 'x' indicates extended commercial temperature range (0°C to +85°C). Confirm package availability and tape/reel options directly with Microchip sales offices or authorized distributors, as packaging identifiers may not appear on the physical device.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring split-architecture advanced I/O control via BC-Link. Ensure the design accommodates the 169-pin LFBGA footprint (11mm x 11mm x 0.8mm). Verify that the host system supports the required LPC interface speeds and that the 3.3V voltage domain aligns with the target platform's power rails.

Application Specific Microcontrollers Part Context

This component serves as the base element in Microchip's multi-device advanced I/O controller architecture. It communicates with companion components using the BC-Link protocol and manages system power states through dedicated suspend supply planes. The device integrates hardware acceleration for interrupts and DMA support for efficient data handling between peripherals and memory.

Application Specific Microcontrollers Replacement Considerations

Consult Microchip documentation for direct pin-compatible alternatives within the MEC16xx series. Verify functional equivalence regarding the ARC-625D core instruction set and peripheral configurations before substitution.
