I. Analogue Evaluation Boards: Precisely Validate Analogue Device Performance, Simplify Signal Chain Development

Microchip's analogue evaluation boards are specifically designed for its range of analogue components (including power management, operational amplifiers, data converters, and sensor interfaces). Their core purpose is to enable engineers to rapidly validate device parameters and optimise analogue signal chains without constructing complex test circuits, significantly reducing development cycles. Each board undergoes factory pre-testing to ensure optimal device performance, while featuring extensive test points and configuration interfaces for flexible parameter adjustment across diverse applications.

Representative models and core features are particularly noteworthy: the MIC24097 evaluation board is specifically designed for the eponymous synchronous buck converter. It employs an adaptive on-time control architecture with an input voltage range spanning 4.5V to 20V, optimised for 1V/20A output scenarios. Supporting CCM/DCM mode switching, it offers precise output voltage regulation, thermal shutdown, short-circuit protection, and other functions, with a maximum switching frequency of 800kHz. Its compact 6mm × 7mm VQFN package makes it ideal for performance validation in high-current power solutions. The EV23P28A evaluation board centres on the MCP16701 PMIC device, integrating eight 1.5A buck DC-DC channels and four 300mA high-precision LDOs. It supports I²C interface configuration and incorporates an on-board load transient generator for rapid load step response testing. Typical applications include power system development for DSPs, MPUs, and FPGAs.

Application scenarios primarily span industrial control, consumer electronics, and automotive electronics. Whether optimising power module efficiency, mitigating analogue signal noise, or ensuring precise sensor data acquisition, this series of evaluation boards enables rapid solution validation and parameter tuning.

II. Memory Evaluation Boards: Efficiently Adapting to Memory Devices to Ensure Data Read/Write Reliability

Microchip's memory evaluation boards cover the full range of memory devices including EEPROM, Flash, and SRAM. Their core function is to assist engineers in verifying memory device read/write speeds, storage capacity, stability, and compatibility. They also provide standardised hardware interfaces and software development kits (SDKs) to support rapid integration into embedded systems. This series of evaluation boards is compatible with Microchip's mainstream MCUs and development tools. Without requiring the development of complex drivers, engineers can directly conduct core verification tasks such as read/write testing, erase testing, and stability testing.

Its core advantages lie in strong compatibility and high usability: compatibility is enhanced by supporting multiple capacities and packaging types on a single evaluation board, reducing development costs; usability is improved through an on-board debug interface that connects directly to a computer. Dedicated software enables real-time monitoring of storage operations, providing an intuitive view of data read/write status and device operating parameters. For instance, the CEC173x evaluation kit (EV42J24A) features four SPI flash sockets, including one 16-pin 256MB SPI flash for fault case demonstrations. It supports evaluation of CEC1736/CEC1734 series devices, enabling verification of SPI flash and root of trust controller interoperability to ensure secure and reliable data storage. Additionally, the SAM9X60-Curiosity evaluation board integrates 4Gb SLC NAND flash and 2Kb serial EEPROM, coupled with 1Gb integrated DDR2 memory. This enables simultaneous verification of memory device compatibility with the MPU, making it suitable for developing storage solutions in high-performance embedded systems.

Application scenarios encompass IoT terminals, industrial control, smart devices, and other domains requiring data storage. It is particularly suitable for scenarios demanding stringent storage reliability and read/write speeds, such as verifying data storage modules in industrial data loggers and IoT gateways.

III. PoE Evaluation Boards: Validating Compliant Power over Ethernet Solutions to Simplify Network Power Development

With the proliferation of Power over Ethernet (PoE) technology across IoT, security, and industrial communications, Microchip has introduced multiple PoE evaluation boards specifically designed for its PoE controllers and PoE managers.

The core features of this evaluation board series centre on standardisation, high integration, and visual monitoring: the EV99F34A evaluation board is designed around the PD77718 PoE manager and PD77010 PoE controller, supporting 8 two-pair ports and 8 four-pair ports. It is fully compliant with IEEE 802.3af/at/bt standards, featuring single-power-supply operation, port LED status indicators, manual reset, and port disable jumpers. Its compact dimensions (15cm × 3cm) enable connection to a computer via USB-C interface for parameter configuration and status monitoring using Microchip's GUI. The EV14G15A evaluation board, based on the PD39208 PoE manager and PD39210 PoE controller, supports 8 x 2-pair ports. It incorporates port status LED indicators, isolated design, and serial communication configuration. Capable of detecting legacy/pre-standard PDs, it features multiple protection mechanisms including overload, overtemperature, and short-circuit protection. It can operate independently or in conjunction with a host CPU.

Primary application scenarios encompass PoE-powered devices such as IP cameras, wireless access points, IoT gateways, and industrial switches. Engineers can rapidly validate critical parameters including power delivery, transmission distance, and compatibility using this evaluation board series, ensuring stable and reliable PoE solutions while accelerating time-to-market.
