Part Details for GC4750-42 by Microchip Technology Inc

Microchip provides a recommended PCB layout in the GC4750-42 evaluation board documentation, which includes guidelines for component placement, routing, and thermal management. Following this layout can help ensure optimal performance and minimize electromagnetic interference (EMI).

To configure the GC4750-42 for low-power operation, refer to the 'Power Management' section in the datasheet. You can adjust the clock frequency, disable unused peripherals, and use the power-saving modes (e.g., sleep, idle) to reduce power consumption. Additionally, consider using a low-dropout regulator (LDO) to minimize power loss.

The GC4750-42 is rated for operation between -40°C and +125°C (junction temperature). However, the recommended operating temperature range is -20°C to +85°C for optimal performance and reliability. Exceeding the recommended temperature range may affect the device's performance, reliability, or lifespan.

To ensure EMC with the GC4750-42, follow proper PCB design and layout guidelines, use shielding and filtering techniques, and implement electromagnetic interference (EMI) mitigation strategies. Additionally, consider using a metal shield or a Faraday cage to enclose the device and reduce radiated emissions.

Microchip recommends using 0.1 μF to 1 μF decoupling capacitors with a voltage rating of 2.5 V or higher, placed as close as possible to the GC4750-42's power pins. The capacitors should be rated for high-frequency operation and have a low equivalent series resistance (ESR) to effectively filter out noise and ripple.
