C8051F041-GQ Accessories and Related Part Numbers

The C8051F041-GQ is a high-performance mixed-signal microcontroller from Silicon Labs. To support its evaluation, development, and deployment, several accessories and related part numbers are available. Below is a comprehensive list organized by category:

1. Development Tools

● Evaluation Kits

• C8051F040DK – Development kit for C8051F04x series, includes evaluation board, cables, power supply, and software.
• C8051F040TB – Target board for evaluating the C8051F040/F041 devices.

● Programmers & Debuggers

• USB Debug Adapter (DEBUGADPTR1-USB) – USB-to-JTAG debug interface for in-system programming and debugging.
• EC2 Adapter (EC2) – In-system programming adapter for connecting the USB Debug Adapter to target boards.
• ToolStick Base Adapter + ToolStick Debug Adapter – Low-cost development and debug solution for Silicon Labs MCUs (not recommended for F04x series, but sometimes used with modifications).

2. Compatible Devices (Same Family / Pin-Compatible)

● Same Package (TQFP-100)

• C8051F040-GQ – Same series MCU without some analog features (e.g., fewer ADC channels).
• C8051F042-GQ / C8051F043-GQ – Variants with different memory and peripheral combinations.

● Other Form Factors

• C8051F041-GM – Same core and features in an MLF-100 package.

3. Reference Designs and Application Boards

• SLSTK2010A – While not directly for the F041, this starter kit is used for general C8051 development and can be adapted.
• Custom Evaluation Boards – Third-party or in-house boards with TQFP-100 socket for testing C8051F041-GQ.

4. Software Support

● Silicon Labs IDEs

• Simplicity Studio – Main IDE for C8051 family (includes drivers, compilers, code examples).
• Legacy IDE – Silicon Labs IDE v4.x for older project support (recommended for C8051F041 legacy users).

● Compilers and Tools

• Keil C51 Compiler – Industry-standard compiler for 8051 microcontrollers.
• SDCC (Small Device C Compiler) – Open-source C compiler for 8051 cores (with limited support).

5. Programming Adapters and Socket Options

• Universal Programmer Socket for TQFP-100 – Used in production environments for flashing the firmware.
• Production Programming Fixtures – Custom-built fixtures for mass programming using DEBUG or ISP interface.

6. Power and Connectivity Accessories

• 3.3V/5V LDO Regulators – For stable operation within MCU's voltage range.
• RS-232 Level Shifters / USB-UART Converters – For serial communication testing.
